[Bearbeiten] Introduction

Documentation of diagnoses is an essential part of many workflows in healthcare systems.

The ways of documenting a diagnosis may depend on the purpose such as medical, statistical, research-related, legal or administrative purposes.

This guideline focusses on the structured electronic documentation of diagnoses for the following applications:

[Bearbeiten] Flag de.svg Germany

Fields of application for diagnosis documentation in Germany are e.g.

  • Capturing a diagnosis for the purpose of billing an ICD-10-GM code under Federal German Code SGB V
    • under law §301 for in-patients
    • under law §295 for out-patients /ambulatory care
    • under law §140 for integrated care plans ("IGV-MVZ")
  • Cause-of-death statistics based on ICD-10 WHO
  • Quality assurance as of law §137 SGB V and related hospital quality reports
  • Infectious disease reporting as required under Infektionsschutz-Gesetz
  • Epidemiology and cancer registers (using ICD-O), including further classification of tumor diseases (1)
  • Expertise by payor for the purpose of retirement plans and statutory insurances (using e.g. ICF)
  • Medical documentation in healthcare such as referral letters, admission letters, sick-leave-notes, prescriptions, in-patient EHRs
  • Clinical studies (MedDRA, WHO-Art)
  • Payor Risk Compensation as of "Risikostrukturausgleich" ruling
  • Product detail information for medication, such as indications, counter-indications amd sideeffects ("UAW")

Administrative documentation of diagnoses will be required for justifying the billing of therapy such as treatment/procedures.

Since Jan 1st 2000 the classification ICD-10 GM as mandatory for diagnosis encoding in both ambulatory and in-patient care, especially for lump sum billing as ruled under G-DRG (German Diagnosis Related Groups).

Primary care data and routine care data may not just be used for billing but also for further purposes. Only standardized guidelines support multiple use of such data.

Statistical processing of diagnostic data may e.g. be used for quality assurance and for research, with diagnoses typically being encoded using classifications, like ICD-10, but also ICD-O and ICF.

For future integrated applications which process structured electronic diagnoses to support medical decision-making processes, advanced terminologies may have to be used, like e.g. the alphabetical index into ICD and medication/substance directories.

Note 1 TNM- and the UICC-System proved to be insufficient for grading tumors of the central nervous systems because of their low metastasis and the weak relationship between tumor size and its aggressiveness. [Louis 2007]. Therefore we will apply the WHO-Grading (see 6.8)

[Bearbeiten] Scope

Scope of this document is an elementary specification of how to represent diagnoses using HL7 V3 messages and documents.

Diagnoses exactly map from symptoms (diagnostic signs) to terms for diseases.

A a principle HL7 represents diagnoses as observations made by a doctor at a patient, which means that diagnostic data will be modelled using the HL7 Observation class, independent of the V3 model being used.

The goal is to have a model-independent specifiation of how to map relevant diagnostic data into the class Observation.

This document is based on using a structured diagnosis.

  • Chapter 3 explains attributes of diagnostic data
  • Chapter 4 explains the use of the Observation class
  • Chapter 5 focusses on the representation of encoded diagnoses, with section 5.1 mentioning specialties of ICD-10 encding especially in the context of German requirements
  • Chapter 6 specifies the representation of diagnoses in tumor documentation.
  • Chapter 7 includes examples representations of diagnosis from vrious fields of application.

[Bearbeiten] Diagnosis Types

[Bearbeiten] Clarification

In HL7 Version 3 the term classification of diagnoses means the type or kind of diagnosis, like e.g. "Admission Diagnosis" or "Referral Diagnosis". For clarity, we will use the term "type of diagnosis" in the following text.

[Bearbeiten] Types of Diagnoses in Ambulatory Care

[Bearbeiten] Flag de.svg Germany

The federal association (KBV) of regional statutory billing associations (KV) for out-patient/ambulatory care in Germany published the so-called KVDT data set as the mandatory format for billing. It combines billing data (ADT, not to be confused with the HL7 ADT data), the rehab billing data (KADT) and the statistical data (STDT) of a GPO reporting to its assigned (regional) KV. Part of the KVDT data set is a diagnosis specification with the following types of diagnosis

Billing Diagnosis - current diagnosis being the basis for billing Continued Diagnosis - diagnoses that are valid for more than three quarters (of a year).

Despite these billing diagnoses it is also allowed to send continued diagnoses (more than one quarter) which are related to the services billed. Using the record attribute 6001 ("ICD-10-code") for continued diagnoses is not permitted, instead the attribute 3673 ("continued diagnosis") shall store the ICD-10-code, combined with attribute 3674 ("reliability - continued diagnosis") and optionally the attributes 3675("side localization - continued diagnosis") or , attribute 3676 ("explanation - continued diagnosis") may be used. Either attributes 6001 or 3673 shall be used.

[Bearbeiten] Types of Diagnoses for Inpatient Care

[Bearbeiten] Flag de.svg Deutschland

The (Federal German Code SGB V) billing law § 301 SGB V states the diagnosis specifications which shall be sent by hospitals to payors. Based on that law, the data transfer guidance „Datenuebermittlung nach §301“ of the federal hospital association DKG has been published. This guidance defines different record types (e.g. admission record, discharge record) which also include diagnosis specifications, as given by the following table:

Record type Segment: Name Diagnosis
Admission Record EAD Admission Diagnosis
Indicator for Continuation DAU Continued Diagnosis - justiyfing sick leave
Indicator for Continuation FAB Diagnosis by specialized clinical department
Discharge Record DAU Continued Diagnosis - justiyfing sick leave
Discharge Record ETL Discharge Diagnosis
Discharge Record NDG Concurrent Diagnosis
Discharge Record FAB Diagnosis by specialized clinical department
Outpatient Procedure RZA Referral diagnosis
Outpatient Procedure BDG Treatment diagnosis

As a result this guidance distinguishes the following types of diagnoses under §301 SGB V:

  • Admission Diagnosis
  • Inpatient Admission Diagnosis
  • Special Department Diagnosis
  • Continued Diagnosis (with sick leave)
  • Discharge Diagnosis
  • Special Department Diagnosis Extension
  • Referral Diagnosis
  • Treatment Diagnosis

Main diagnoses and concurrent diagnoses (as defined by medical aspects) as well as primary and secondary diagnoses shall be represented via additional attributes.

Regarding further diagnosis types please see Annex A

[Bearbeiten] Common Diagnosis Descriptions

[Bearbeiten] Introduction

This chapter gives the attributes that are common parts of a structured diagnosis specification which are required for processing an electronic diagnosis information.

[Bearbeiten] Plain-Text Description

This attribute describes the diagnosis through prosaic text, hate.g. may be entered via a text entry field by the medical professional. This plain text description should be a mandatory part of medical documentation.

Example: Allergic asthma

Note that plain-text descriptions will not necessarily match the associated text of diagnosis codes, like the ones from the systematic classification ICD-10.


[Bearbeiten] Diagnosis Code

For the purposes of administrative and statistical processing, diagnoses are being encoded by encoding systems. E.g. ICD-10 is mandatory under billing according to (Federal German Code) SGB V §391 and §295.

Further systematic encoding systems are e.g. „Alpha-ID“, SNOMED CT and ID MACS.

Example: J45.0

[Bearbeiten] Diagnosis Code – Catalog Text

The catalog text is the associated text for a given diagnosis code. It does not have to match the plain text and can be rendered by an automated system - based on a given diagnosis code.

Example: Predominantly allergic asthma

[Bearbeiten] Diagnosis Type

The diagnosis type further specifies the type of a diagnosis and will be given in an encoded form. Examples may be "referral diagnosis", "admission diagnosis", "discharge diagnosis" etc.

[Bearbeiten] Diagnosis Date

This attribute describes date and time when a medical professional made the given diagnosis.

[Bearbeiten] Documentation Date

This attribute describes date and time when the diagnosis was documented.

Note that when there is no need to distinguish both dates, the diagnosis date shall be used.

[Bearbeiten] Specification of the Clinically-Relevant Time of a Diagnosis

This attribute is a time interval specified by a start time and end time information giving the time in which the patient suffered from the specified disease.

Giving only a start date documents the time since when the patient had that diagnosis.

The start date may be different from the diagnosis date.

Date information in diagnoses may be with different precision.

Examples: Diabetes since 2006 or Fracture of Femur on March 12th, 2007

[Bearbeiten] Diagnosis Reliability

This attribute describes the reliability of the specific diagnosis.

[Bearbeiten] Flag de.svg Germany

For billing under ambulatory/out-patient care (under Federal German Code SGB V) defined attributes (suffices A, G, V or Z) are compulsory while such attributes are not allowed for in-patient billing (under Federal German Code SGB V).

[Bearbeiten] Localization

The localization attribute specifies in which body site (topography) the disease was diagnosed.

Both plain text or encoded terms are allowed.

An example is the ICD-O site code for tumor documentation.

As a suffix the side may be used.

[Bearbeiten] Explanations

This attribute allows medical professionals to document detailed explanations using a plain text.

[Bearbeiten] Reasons for Exceptions

This plain-attribute may be required to justify a diagnosis e.g. in the context of billing.

[Bearbeiten] Diagnosis Model in HL7 V3

[Bearbeiten] Summary

Diagnoses represented in HL7 V3 shall useu the class Observation, which is modelled as shown in fig. 1.

Detailed descriptions of classes and data types in this model can be found in the related HL7 V3 documentation and Data Type Guidelines.

The following sections specifiy how diagnosis attributes shall be mapped into the Observation model.

[Bearbeiten] Plain Text

value.originalText diagnosis as a plain text ST[0..1]

Plain text descriptions of the specific diagnosis shall be stored in the subelement originalText of element value. If it is not necessary to specify a text or should this text not be available, the @nullFlavour attribute shall be used. This element shall explain the reason why there is no plain text. A value of "NAV" states that no coded text is available (yet). More values are described in the HL7 documentation.

The attribute @language of subelement originalText may be used to specify the language of the prosaic diagnosis text.


<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <value xsi:type="CD" nullFlavor="NAV">
      <originalText>Rektumkarzinom mit Höhenlokalisation ab Anokutanlinie/Linea dentata
      </originalText>
    </value>
  </observation>

[Bearbeiten] Diagnosis Code and Text

value Diagnosis Code CD[0..1]

Representing a diagnosis via a code and its associated text shall be done va the value element (in the model: an attribute of the Observation class).

The XML attribute @code shall store the diagnosis code and @displayname shall store the associated diagnosis text.

Such a structured representation of e.g. an ICD10 coded diagnosis looks like this:

The XML attribute @codeSystem shall store the OID for the specific ICD-10-GM version being used and the @codeSystemName attribute shall store the plain text name of the coding system and version.


  <!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
  ...
    <!-- ICD-Code of a diagnosis -->
    <value xsi:type="CD" code="I01.0"
      displayName="Akute rheumatische Perikarditis"
      codeSystem="1.2.276.0.76.5.311" codeSystemName="icd10gm2006"/>
    ...
  </observation>

[Bearbeiten] Diagnosis Type

code classification code CD CW[1..1]

The XML attribute shall specifiy the classification code using the attribute @codeSystem for storing the OID of that coding system (also see Annex <10>)

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
     <code code="DX" codeSystem="1.2.276.0.76.5.342"/>
     ...
  </observation>

[Bearbeiten] Diagnosis Date

author.time Diagnosis Date IVL<TS>[0..1]

The diagnsis date shall specify when the diagnosis was made as the time in the clinical process which is not necessarily the documentation date. The diagnosis date shall be represented using the author instance which shall be connected via Participation to the current Observation instance. Instances of author contain a model attribute time of type IVL<TS>. Detailed information regarding the person giving the diagnosis shall be modelled using an instance of assignedEntity.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <author>
      <!-- Diagnosedatum -->
      <time value="20100111"/>
      <assignedAuthor>
        ...
      </assignedAuthor>
    </author>
    ...
  </observation>

[Bearbeiten] Documentation Date

dataEnterer.time documentation date TS [1..1]

The documentation is the date when the diagnosis has been entered by e.g. a clinician. The data value is mapped to an instance dataEnterer which is related via a Particpation to the Observation instance (see fig. 1 Observation Model).

The dataEnterer class has an model attribute time of type TS, such that in XML the data value will be mapped into an element time and an XML attribute @value.

In case there is no dataEnterer instance, the participation relation with its model attribute typeCode=ENT also manages a participationRole instance representing the data entering person that would otherwise be modelled through a instance of dataEnterer.

<!-- structured representation of diagnosis -->
  <observation classCode="OBS" moodCode="EVN" negationInd="true">
  ...
  <!-- documentation date -->
    <participant typeCode="ENT">
      <time value="20060606"/>
      <participantRole>
        ...
      </participantRole>
    </participant>
    ...
  </observation>

[Bearbeiten] Diagnosis Time Interval

effectiveTime diagnosis time interval IVL<TS>[0..1]

The model attribute effectiveTime of class Observation specifies the time interval for which the specified is (or, has been) clinically relevant.

In XML, the sub-element low shall specify the begin data and sub-element high shall specifiy the end date. Dates for low or high may also be specified without the other.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <effectiveTime>
       <low value="20050127"/>
    </effectiveTime>
    ...
    </observation>

[Bearbeiten] Diagnosis Reliability

value.qualifier diagnosis reliability CR [0..1]

the diagnosis reliability shall be represented in the model attribute value using a sub-element qualifier.

   <!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <value xsi:type="CD" nullFlavor="NI">
      <originalText>......</originalText>
      <!--diagnosis reliability -->
      <qualifier>
        <name code="8" codeSystem="2.16.840.1.113883.3.7.1.0"/>
        <value code="G" codeSystem="2.16.840.1.113883.3.7.1.8"/>
      </qualifier>
    </value>
  </observation>

XML attribut @code in name shall specify the name of the diagnosis reliability qualifier, based on the table given below. XML attribut @codeSystem shall specify the OID of the system giving these qualifier names. The diagnosis reliability shall be specified using XML attribute @code in the XML element value.

[Bearbeiten] Flag de.svg Germany

For out-patient care (§ 295 SGB V, Germany) diagnosis reliability attributes are mandatory, while for in-patient care (§ 301 SGB V) they are forbidden i.e. must not be specified. (Source: DIMDI)

Code as of §295 SGB V Implementation Meaning Explanation
G certain diagnosis validated
V uncertaintyCode=UN suspicious suspicion diagnosis
Z state after an earlier diagnosis is related
A negationInd=true excluded this diagnosis has been excluded (use negationInd in Level 3)

Table 2: Vocabulary Domain for Reliability Codesystem: Sciphox (OID: 2.16.840.1.113883.3.7.1.8)

In tumor documentation the validation of diagnosis is also documented by specifying the (superior) way of diagnosis. This information shall also be specified through the qualifier:

Code Implementation Meaning Explanation
k clinically
z zytologically
h histologically
a autoptically
d DCO Death certificate only.
nullFlavor = OTH Other
nullFlavor = NI unknown

Table 3: Vocabulary Domain for Diagnosis procedure in tumor documentation Codesystem: (OID: 1.2.276.0.76.5.418)

[Bearbeiten] Localization

targetSiteCode Lokalisation CD CWE [0..1]

Localization of diagnoses shall be specified using the model attribute targetSiteCode. For localizations given as plain text the sub-element originalText of targetSiteCode shall be used. In case no localization code is available, the XML attribute @nullFlavor shall be specified.


<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <targetSiteCode nullFlavor="NI">
      <originalText>Oberhalb des rechten Knöchels</originalText>
    </targetSiteCode>
    ...
  </observation>

If a structured code is available, then model attribute targetSiteCode shall have a code sub-element with the code being specified in XML attribute @code and the coding system being specified using XML attribute @codeSystem.


Optionally the XML attribute @displayName may be used to specifiy a plain text for the code and @codeSystemName may be used for the name of the coding system.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <targetSiteCode code="299058009" codeSystem="2.16.840.1.113883.6.96"
    codeSystemName="SNOMED CT" displayName="kleiner Finger">
      <qualifier>
        <name code="78615007" codeSystem="2.16.840.1.113883.6.96"
              codeSystemName="SNOMED CT" displayName="mit Seitenlokalisation"/>
        <value code="24028007" codeSystem="2.16.840.1.113883.6.96"
               codeSystemName="SNOMED CT" displayName="rechts"/>
      </qualifier>
    </targetSiteCode>
    ...
  </observation>

Note: The localization codes suggested by the German health Ministry (BMG) shall only be used together with diagnoses encoded in ICD 10 (German).

Additional codes for the side localization may be used in out-patient care as well as in-patient care(see 4).

In tumor documentation further codes shall be use for the side localization:


Code Implementation Meaning Explanation Common Diagnoses Tumor Diagnoses
R Right side localization right X X
L Left side localization left X X
B both side diagnosed on both sides X X
M middle line middle line zone - 1 inch left or right from middle line X
nullFlavor = NA system disease in the sense of 'not applicable' X
nullFlavor = UNK unknown X X

Table 4: Vocabulary Domain for Localization Coding System: (OID: 1.2.276.0.76.5.412)

4 DIMDI 5 Literatur: Basisdokumentation für Tumorkranke 5. Auflage 1999; Dudeck et al


The side localization is used for diagnosis documentation for common and also for tumor documentation, but with differeent value sets, which are defined as follows:

Value Set Explanation OID
Common, based on ICD-10 2.16.840.1.113883.3.7.1.7
Tumor Documentation 1.2.276.0.76.11.10

Table 5: Value Sets for Localization

[Bearbeiten] Explanations

text explanation of diagnosis ST [0..1]

Any explaining text shall be represented using the XML attribute text.

A structured representation will look like this:


<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    <value xsi:type="CD" code="J45.0" codeSystem="1.2.276.0.76.5.311"
      displayName="Vorwiegend allergisches Asthma bronchiale">
      <originalText>Allergisches Asthma</originalText>
    </value>
    <text>Intermittierend, seit der Jugend</text>
  </observation>

[Bearbeiten] Reasons for Exceptions

value Reasons for Exceptions ST [0..1]

Billling-related exceptions shall be encoded using the @value attribute of an extra Observation instance being related via an ActRelation-Ship instance to the original describing instance of Observation.

A structured representation will look like this:

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <!-- reason for exception-->
      <entryRelationship typeCode="RSON">
        <observation moodCode="EVN" classCode="OBS">
          <code nullFlavor="UNK"/>
          <value xsi:type="ED">...........</value>
        </observation>
      </entryRelationship>
    ...
  </observation>

XML attribute @typeCode shall have the value RSON (= reason) specifying an exception for billing purposes.

[Bearbeiten] Using more Attributes of Observation

This section describes more model attributes of Observation that may play a role in describing diagnoses.

[Bearbeiten] Attribute 'id'

id diagnosis identificator SET <II>[0..1]

The model attribute id should be used to identify the instance of a diagnosis - which is recommended for computer-based processing of diagnoses in order to refer to the clinical specification of that diagnosis.

In XML representations the XML attribute @extension shall store the diagnosis identifier while the XML attribute @root should specify the OID of the diagnosis database.

In case changes or deletions have to be communicated for this diagnosis instance, this id will provide reference.

[Bearbeiten] Attribute 'classCode'

@classCode classCode <= OBS

XML attribute shall be 'OBS' - specifiying Observation as the main type of the Act instance used for documenting the diagnosis.

In XML an attribute @classCode of the element Observation represents the model attribute 'classCode' of class Observation.

[Bearbeiten] Attribute 'moodCode'

@moodCode Mood Code <= EVN

Attribute @moodCode specifies how to interpret the containing Act instance.

When using an Observation to specify a diagnosis, the @moodCode shall have the value EVN, indicating that the Observation documents an earlier action.

[Bearbeiten] Attribute 'negationInd'

@negationInd Negation Indicator BL [0..1]

The optional attribute @negationInd is of data type BL with values 'true' or 'false'.

Specifying a 'true' value states that the specified diagnosis has been excluded.

@negationInd is optional, the default is 'false'. If not specified, the receiving system will interpret the diagnosis as specified.

[Bearbeiten] Attribute 'statusCode'

statusCode Statuscode <= completed

This attribute can be use to represent the state of the containing Act, which can be in states like e.g. "new", "active" or "cancelled". As diagnoses are considered the documentation of an action already completed, the fixed value "completed" shall be used in XML attribute @code of sub-element statusCode.


[Bearbeiten] An Example

A small example shows all of the above attributes:

  <observation classCode="OBS" moodCode="EVN" negationInd="true"><statusCode code="completed"/></observation>

[Bearbeiten] Representation of Diagnosis in specific Codesystems

[Bearbeiten] ICD-10-GM-coded Diagnoses

The „International Statistical Classification of Diseases” (ICD) is a classification system for diseases and related health issues. It has a hierarchical structure. As the german localized version ICD-10-GM is a varient of the ICD-10 released by WHO.

Diseases are specified through alphanumeric codes. Each disease has a unique code and vice versa. The majority of codes are so-called primary diagnosis keys, i.e.they contain all information to encode a given diagnosis.

[Bearbeiten] Flag de.svg Germany

ICD also provides the ability to specify secondary keys for additional information. Such secondary keys must only be used together with a primary diagnosis and are marked through asterisk (*) or exclamation (!) as additional codes .

Primary diagnosis codes either have no prefix or a cross (+).

Example.: E14.30+, H28.0* ICD-10 Code for “Diabetes mellitus with cataract“

[Bearbeiten] Terms of ICD-10 Codes

ICD-10-GM will be used for encoding diagnoses in both in-patient and ambulatory care. In-patient diagnosis encoding additionally has to adhere to the German coding guidelines (§ 301, Deutsche Codierrichtlinien) and the extensions authorized by the Health Ministry (BMG).

For ambulatory care, the WHO-Table with BMG-extension is to be used.

[Bearbeiten] Secondary Codes

ICD-10 GM distinguishes between primary codes and secundary codes.

Primary codes are codes without suffix or with a cross(+).

Secondary codes are those codes with an asterisk (*) or an exclam (!).

In oorder to explain their meaning we will translate some quotes of „Basiswissen Kodieren“ [Basic Encoding Knowledge by DIMDI,www.dimdi.de]

"The code for etiology (cause, origin) of a disease shall be marked with a cross (+) and its manifestation with an asterisk (*) - with the cross-code being the primary code and the asterisk-code never being used alone."

Another translated quote:

„ Asterisk codes shall only be those that are marked as explicitly permitted in ICD-10 for the asterisk-suffix."


„ Provided that the secondary code is permitted for asterisk, any other code describing the underlying disease may be used as primary code with the cross-suffix."

„... Some Codes are being marked with an exclam (!) indicating that therse are further descriptions or definitions of the severity. Such codes must not be used alone“ (without primary code).

As a result, each diagnosis must at least have a primary code and optionally secondary codes.

Each primary/secondary code is the alphanumeric string given by ICD-10 code followed by the suffix, either (†, *, !)

[Bearbeiten] Side Localization

Regarding the encoding of side localizations, we translated a section from „ICD-10- Bekanntmachung des BMGS“ ("ICD-10 Communications of the German Health Ministry", 2004)

„..for the application of ICD-10-GM the following holds: When encoding the side localization, the following suffices may be used: – right: R – left: L – both sides: B ...“ [BMGS, 2004]

As a result, for each ICD-10 code, an independent side localization suffix can be appended. Note: primary code and secondary code can have different side localizations.

Example: C50.4 R Mamma Ca - right J91* L Pleural effusion in conditions classified elsewhere - left

For tumor documentation the extended table is valid.

[Bearbeiten] Reliability of Diagnoses

„... When using ICD-10-GM according to § 295 SGB V (ambulatory sector) additionally the following holds: For encoding the diagnosis reliability one of the follwing suffices must be used: – for an excluded diagnosis: A – for a suspected diagnosis: V – for state (without symptoms) after the given diagnosis: Z – for a validated diagnosis: G“ [BMGS, 2004, translated by author]

As a result, ambulatory diagnoses used in the context of „Abrechnung ärztlicher Leistungen“ (billing of medical services, fixed term in the German statutory GP system acc. to german federal regulation §295 SGB V) the specification of diagnosis reliability is mandatory.

For in-patient care these suffices MUST NOT be used.

[Bearbeiten] Mapping of ICD-10-coded Diagnoses into HL7 v3

Structured representations of ICD10-encoded diagnoses must support primary and secondary codes, code extensions, side localizations and reliability . The primary code represents the main disease. The secondary code extends the primary code and is either used to describe manifestations in organs ("asterisk") or the cause (etiology, e.g. which bacteria) of the main disease ("exclamation") In order to represent this dependency, an additional oberservation instance will be connected via the ActRelationship to that Observation instance containing the primary code.

So we have the following basic structure for ICD10-encoded diagnoses:

27px

Figure 2: Class Diagram of ICD-10 Diagnoses in HL7 v3

The attribute typeCode in the ActRelationship shall represent the code extension

The related Observation instance (connected via the ActRelationship) has MFST (Manifestation) as its typeCode in order to represent 'asterisk"-codes.

Exclamation-Code extensions are being represented as Observation instances connected via ActRelationships with typeCode CAUS (Cause).

The resulting XML structure of an ICD-10 encodeded diagnosis looks like this:

<!-- Structured Representation of Diagnosis-->
   <observation moodCode="EVN" classCode="OBS"><!-- Primary Code-->
      <value xsi:type="CD" code=" E14.30" codeSystem=" 1.2.276.0.76.5.311"/>
      <entryRelationship typeCode="MFST">
         <observation moodCode="EVN" classCode="OBS"><!-- Secondary Code-->
            <value xsi:type="CD" code=" H28.0" codeSystem=" 1.2.276.0.76.5.311"/>
         </observation>
      </entryRelationship>
   </observation>

In this case the containing ActRelationship instance is of class entryRelationship- repesented by an element of that name.

Attribute @typeCode has MFST as a fixed value for representing an asterisk code.

value.@code ICD-Code ST [1..1] XML-Attribute @code shall store the specific ICD-10 Code.

value.@codeSystem OID of ICD-Codeset UID [1..1] XML-Attribute @codeSystem shall keep the OID of the ICD-10 Version being used. The appendix gives hints towards versions being used in practice.

value.@codeSystemName Name of ICD-10 Version ST [0..1] XML-Attribute @codeSystemName may store the Name of the used ICD-10 Version.

value.@displayName ICD-Code Text ST [0..1] XML-Attribute @displayName may store the verbose text of the ICD-Code.

OIDs and names of ICD-10 versions may be obtained from DIMDI (www.dimdi.de)

[Bearbeiten] Representation of Side Localisation

value.qualifier Side Localisation CR [0..1]

The side localisation code shall be represented using the child element qualifier of the value element, as it refines the specification of that diagnosis code (as decided by HL7 DE TC meeting on 2005-09-01, minutes item 1.3.2).

An example representation looks like this:

<!-- Structured Representation of a Diagnosis -->
   <observation moodCode="EVN" classCode="OBS">
      <code code="DX" codeSystem=""/>
      <!-- Primary code-->
      <value xsi:type="CD" code="E14.30" codeSystem="1.2.276.0.76.5.311">
         <qualifier>
            <name code="7" codeSystem="2.16.840.1.113883.3.7.1.0"/>
            <value code="L" codeSystem="2.16.840.1.113883.3.7.1.7"/>
         </qualifier>
      </value>

[Bearbeiten] Specifying a Diagnosis using a Thesaurus Index

One more way of specifying a diagnosis is by using an index referring to an entry in a medical thesaurus.


[Bearbeiten] Example: Mapping an Alpha-ID-coded Diagnosis

[Bearbeiten] Flag de.svg Germany

As an example, the diagnostic thesaurus „Alphabetische Verzeichnis zur ICD-10 GM“ (alphabetic directory of ICD-10 GM) is being used in Germany.

This directory allows to locate a verbose description of ICD-10 terms and to find the corresponding ICD-10 GM code.

The so-called Alpha-ID has been developed to process entries of that alphabetic directory.

It is an identification number for each textual entry in the "alphabetic directory".

In order to find this alpha-ID, a mapping file has been provided by DIMDI (www.dimdi.de).

The Alpha-ID is needed because in medical documentation, the descriptions of diagnoses need to be more differentiated than what ICD-10 codes actually can express.

Using the alpha-ID allows for a much finer granularity of diagnosis descriptions.[DIMDI,Alpha_Id].

As an example the ICD-10 Code “A01.0 Typhus caused by Salmonella typhi“ encodes multiple diagnoses such as „liver typhus“, „lung typhus“ and many more.

By using the Alpha-Id it is possible to specify the specific type of typhus, like e.g. „liver typhus“ as„I18721“ and „lung typhus“ as „I21312“.

Figure 4 shows an excerpt of the metafile which defines the fields of the mapping file for the Alpha-Id.

Each record consists of six fields, each being separated by a semicolon.

The fields in each record contain the following data:

  Field 1: Validity (0-not valid, 1-valid)
  Field 2: Stable Identification with prefix I or T ("Alpha-Identifikationsnummer")
  Field 3: Primary key (with cross)
  Field 4: Asterisk key (with asterisk)
  Field 5: Additional key (with exclamation)
  Field 6: Related text

Figure 4: Excerpt from Alpha-ID metafile „icd10gm_alphaid_edv_ascii_liesmich.txt“


A structured representation of a thesaurus uses the @value attribute of class Observation and an example instance lloks like this:

   <observation moodCode="EVN" classCode="OBS"><value xsi:type="CD" code="I2173" codeSystem="1.2.276.0.76.5.309" codeSystemName="alphaid2006"/>
   ...
   </observation>

value.@code Alpha-Id ST [1..1] XML-Attribute @code stores the index referring to an enty in the „Alphabetisches Verzeichnis“

value.@codeSystem OID ofAlpha-ID UID [1..1] XML-Attribute @codeSystem stores the OID of the Alpha-ID Version being used.

value.@displayName Alpha-Id Text ST [0..1] XML-Attribute @displayName may be used to display a text related to the current Alpha-Id

value.@codeSystemName Name of Alpha-ID Version ST [0..1] XML-Attribut @codeSystemName represents the Name of the coding system, in our case alphaid2006.

OID and name of ICD-10 Version can be obtained from DIMDI (www.dimdi.de)

[Bearbeiten] Diagnosis Specification using Identifiers in a Nomenclature

One way of specififying a diagnosis is to use the code representing a diagnostic term in some medical nomenclature.

A well-known nomenclature in medicine is SNOMED-CT ("systematic nomenclature of medicine - clinical terms")

Compared to ICD-10 it has more concepts for diagnoses and mostly does not classify.

In general using a term of a nomenclature often preserves more information than using a term of a classification.

Classification is selecting a common representation for a set of concepts that are (under some aspect) considered similar.

As a result, classification reduces information, which is demonstrated by the following examples

I.e. as a part of clinical documentation of diagnosis the encoding using alpha-id or some identifier in a nomenclature would be preferred over using a classification like e.g. ICD-10.

The example shows concepts all being represented through the same ICD-10 code Q92.8 for 'Other specified trisomies and partial trisomies of autosomes'.

A simple comparison of codes from nomenclatures gives an example of missing clarity and precision of the ICD-10 classification.

Diagnosis ICD-10 Code Alpha-ID Snomed CT ID MACS
Imbalanced Insertion Q92.8 I87548 254262003 M002405-D62839-58
Trisomy 22 Q92.8 I81282 205655003 M001897-D55549-58
Trisomy 20 Q92.8 I81283 53346000 M002406-D55530-58
Partial Trisomy a.n.k. Q92.8 I81284 133849008 M001D1C-C78409-58

Table 6: Diagnoses in different coding systems


[Bearbeiten] Precoordinated and Postcoordinated Concepts of a Nomenclature

For specifiying a diagnosis using a terminology there are two fundamental approaches:

The pre-coordinated approach selects a fixed term among a comprehensive list with representations for all possible concepts.

The list of all pre-coordinated terms limits the set of concepts which can be represented.

The post-coordinated approach constructs each term out of (more or less independently) encoded aspects of the concept to be represented.

The resulting term is the combination of the encoded aspects of the given concept.

ICD-10 is a good example of a pre-coordinated terminology, as it lists all the terms for the concepts it can represent.

The cross-asterisk extension to ICD-10 is an example of post-coordination.

More info can be found under the Terminfo project [Terminfo] of HL7 International.

[Bearbeiten] Diagnosis by Thesaurus Index or Term within a Nomenclature

A term in a nomenclature is specified through the @value attribute of class Observation.

An example (SNOMED CT) of the structured representation looks like this:

   <observation moodCode="EVN" classCode="OBS">
   ...
   <value 
      xsi:type="CD" code="314888007" 
      codeSystem="2.16.840.1.113883.6.96"
      codeSystemName="SNOMED CT"
      displayName="Typ-II-Diabetes with diabetic cataract"/>
   ...
   </observation>
[Bearbeiten] Attribute value.@code Index or Term in Nomenclature

CD CWE [1..1] The XML attribute @code keeps the index referring to an entry in a thesaurus or nomenclature.

[Bearbeiten] Attribute value.@codeSystem OID of Nomenclature

UID [1..1] The XML attribute @codeSystem stores the OID of the thesaurus or nomenclature.

[Bearbeiten] Attribute value.@displayName Text

ST [0..1] Through the XML attribute @displayName a plain text related to the index can be given.

[Bearbeiten] Attribute value.@codeSystemName Name of Nomenclature

[0..1] The XML attribut @codeSystemName describes the name of the thesausrus or nomenclature.

[Bearbeiten] Representation of Cancer Diagnosis

[Bearbeiten] Introduction

In this chapter, diagnostic aspects of documentation of tumor diseases will be described. Different aspects of diagnostical descriptions of tumor diseases are described by ICD-O (Oncology) and by further classifications to document the expansion (tumor spread) or diseases stage, respectively, the latter one mostly being classified by the TNM-System.

Especially for hemato oncological diseases (Leukemias and Lymphomas), other systems (e.g. Ann-Arbor-Classification) are used. TNM-System discribes:

  • Expansion of primary tumor (extent or, spread in distant organs repectively)
  • Affection of lymph nodes in lymph flow area
  • Existence of distant metastases.

For non-TNM–-classifiable diseases or in addition to the TNM-System there are a number of further classification systems:

  • Ann Arbor
  • Rai
  • Binet
  • CML-Phasen
  • FAB
  • Durie and Salmon
  • Gleason-Score

Discriptions can be found here: http://www.med.uni-giessen.de/akkk/gtds/grafisch/doku/bd5f.htm http://www.tumorzentren.de/tl_files/dokumente/adt_basis.pdf

This list probably will be always incomplete because of the medical progress.

[Bearbeiten] ICD-O

Third Edition of ICD-O [DIMDI, WHO] is the topical one. ICD-O consists of two axes, Topography- and Morphology-Axis. In ICD-O, tumor can be classified by

  • Site
  • Tissue Structure (Histology)
  • Biological behaviour (Dignity)
  • Tissue grading (mostly in two or four stages)

In this case, tissue structure and tissue grading is redundant. Precisely: The first four digits of morphology-code describe tissue-type. The fifth one describes biological behaviour (dignity-code):

  • /0 = benign
  • /1 = neoplasm with uncertain or unknown behaviour
  • /2 = Cancer in situ
  • /3 = malignant, primary tumor
  • /6 = malignant, metastasis (not used in tumor documentation)
  • /9 = malignant, uncertain wether primary tumor or a metastatic

The sixth digit describes grading, differentiation or phenotype (Histology/Pathology):

  • 1 = Grade I, well differentiated (Low grade)
  • 2 = Grade II, moderately differentiated (Intermediate grade)
  • 3 = Grade III, poorly differentiated (High grade)
  • 4 = Grade IV, undifferentiated (High grade)
  • 9 = Grade IX, grade cannot be assessed

For Leukemias and Lymphomas, the sixth digit signifies the immunophenotype

  • 5 = T-Cell
  • 6 = B-Cell, Pre-B-Cell, B-Ancestor-Cell
  • 7 = Null-Cell, Not-T-Cell-Not-B-Cell
  • 8 = NK-Cell, Natural Killer Cell
  • 9 = Determination of Cell Type was not accomplished, not specified or not applicable

TNM System describes

  • Expansion of primary tumor (extent repectivly spread in distant organs)
  • Affection of lymph nodes in lymph flow area
  • Exisistence of distant metastasis

For the topography axis, there exists an (hierarchical) enlargement, the ‘localisation key’ (Wagner, G. (HRSG.): Tumorlokalisationsschlüssel, 5. Auflage, Springer Verlag, Berlin, Heidelberg, New York, Tokyo 1993), which can supply at some positions clinical relevant differentiation. The morphology axis is composed of a four-digit code for tissue basic structure, a characteristic number for dignity and an additional grading item. The key itself does not contain all possible combinations of histology and dignity, but points out those ones, for whome exist special discriptions. Vice versa not all combinations of basic structure and dignity are possible (so there is no ‘benign leukemia’). Not either there is a grading system available for all kinds of tumor. For some ones, additional information (for Example ‘Cell-line’) is used at the corresponding position.

[Bearbeiten] Tumor Localization

For Tumor-Coding first of all, the site is important. It will be classified by the Topography -Axis of ICD-O. Topographical -Codes of ICD-10 are based on chapter II (Neoplasm –C 00 – C 97) of ICD-10. However, some of the topographical Codes of ICD-10 (Codes) are not used, because their content is discribed by histology- and digit-Codes of ICD-O. (e.g. Differentiation in situ/ infiltrated, melanoma vs. scin cancer).

[Bearbeiten] Tumor Histology and Dignity

Furthermore, in ICD-O, tumor morphology i.e. tissue structure (histology) and biological behavior (dignity) is discribed by special Codes. Tumor histology is coded by a four-digit number, which is assumed of the morphology-axis of Standardized Nomenclature of Patholoy (SNOP). Dignity-Code is attendant on morphology-Code, seperated by /. Examples:

  • 8060/0 squamous epithelium - papillomatose
  • 8070/2 squamous epithelium – cancer in situ undifferentiated
  • 8070/3 squamous epithelium – cancer undifferentiated
  • 8070/6 squamous epithelium – cancer metastasis undifferentiated

[Bearbeiten] Tumor Grading

Grading is derived from the comparison of primary tissue with the neoplasm of this tissue. There are five grading-degrees (s.o.) and further three degrees for Malignant Lymphoma. Registration of tumor grading is also provided in TNM.

[Bearbeiten] Qualifier of Tumor Formula

ICD-O –Codes can be specified by the following qualifier:

Here ICD-O provides additionally the following codes for Lymphoma, which specify the Cell line: B-Cell, T-Cell, Null-Cell Lymphoma. ICD-O uses the Codes 1 – 9. A detailled System is discribed in Chapter 9 under 9.5.2 and 9.53.

[Bearbeiten] Example

GRAPHIC IS MISSING

DisplayName is only available in correlation to qualifiers. According to ICD-O-3 formation rule there are much more discriptions possible as ICD-Catalog proposes.


[Bearbeiten] TNM Classification

The TNM classification describes the expansion (spread) of the tumor , i.e. stadium and prognosis of the disease.

As a special feature, the TNM classification uses the same notation for all tumors but supports different interpretations for different entities.

As an example, a T3 for mamma carcinoma has a different interpretation than the stomach carcinoma.

The current edition is 7th which is valid since January 2010, which is a reason why many TNM-6- codes may still be in use. Therefore all TNM-codes should have a version identifier, because non translatable differences are in the different editions.

A simple overview can be found in http://de.wikipedia.org/wiki/TNM.


The T category will be used for the expansion of the primary tumor, where the stages T0, Tis, T1-T4 und TX are being used, the "higher" the number, the more progress is being diagnosed and the more adverse the prognosis.

T0 stands for "no primary tumor found" (e.g. because being eradicated by therapy) Tis stands for a very early (non-infiltrating) stage tumor (Tumor in situ) and TX stands for a diagnosis which can not judge the stage because of missing data

For some tumors subcategories like e.g. T2a, T2b have been defined.


The N-category classifies the affection of lymphatic nodes - usingN0, N1-N3, NX, where N0 means "no lymphatic node affected".

For some tumors, this exclusion ("N0") requires the examination of a minimum amount of nodes.

The higher the N category the more severe is the lymphatic node affection.

If no sufficient data is available NX is being diagnosed.


The M category describes the existence of distant metastases, with the vallues of M0 (no metastases detectable), M1 (metastases detectable) and MX (insufficient data).


The TNM can be used according to clinical criteria (preoperative, cTNM) and according to the pathology findings (pTNM).

For many patients one single diagnoss will be made, either a cTNM or a pTNM, such that this type of finding must be distinguished.

This preoperative ("c" or no prefix) / pathology ("p") attribute can be captured independently for each of the T N M categories.

Therefore the typically used pTNM often meanes pTpNcM, because the spread of a timur can best be diagnosed through surgery while lymphatic spread only by pathology.

The prefix "r" describes remaining tumors (after non-disease intervals) and a prefix "y" if the classification was assessed after systemic or radiation treatment (ycTNM, ypTNM etc.).

For multiple Primary tumors the suffix "m" (or the number of tumors) will be put after the T-category value(T2(m), T2(5)).


Therefore a complete TNM formula looks like this:

There are voluntary components e.g. the certainty-Faktor (C-Factor)

Other components require pathology lab examination (L-, V- or Pn-Category)

  • y-Symbol (y or empty, disgnosis after systematic or xray treatment)
  • r-Symbol (r or empty, remainder)
  • p/c/a-Symbol for pT-category (clinical or pathological)
  • T-Category
  • (m) for multiple localizations or number of tumors
  • C-Factor for T-Category (certainty)
  • L-Category
  • V-Category
  • Pn-Category
  • p/c/a-Symbol for pN-Category (clinical or pathological)
  • N-Category
  • C-Factor for N-Category (certainty)
  • p/c/a-Symbol für pM-Category
  • M-Category
  • C-Factor for M-Category (certainty)
  • S-Kategorie (serological values, only for testicle tumors)
  • UICC-Stadium (Grading via UICC 0 and I-IV together with

letter A, B and C for further classification).

For some tumors further modifiers are being documented as a suffix (mostly in parenthenses) like e.g. (sn), (mol-),(mol+).

In addition, the TNM supplement introduces innovative or "under test" extensions, which raises doubts whether ta full control of TNM entries.

Typical T-Categories (without pre-/suffices) are being listed in chapter "Sites"

Typical N-Categories (without pre-/suffices) are being listed in chapter "Nodes".

Typical M-Categories (without pre-/suffices) are being listed in chapter "Metastases".

[Bearbeiten] Qualifiers of the Tumor Formula

Despite values for T,N and M the TNM formula may also contain various qualifiers. The following table gives an overview which qualifiers can be used for which information and where they are being used. This is case-sensitive!

  • a Autoptical
  • c Clinical
  • C C-Factor (certainty)
  • G histopathological Grading
  • L Lymphatic vessel invasion
  • m multiple Tumors
  • M distant metastases
  • N Regional lymphatic node metastases
  • p pathological
  • Pn perineural Invasion
  • r Rezidiv tumor
  • R Residual tumor after treatment
  • sn Sentinel-Lymphatic nodes
  • Stage Anatomic Stage-Grouping
  • T Expansion (spreading) of Primary tumor
  • V Venous invasion
  • y Classification after initial multi-modal Therapy

[Bearbeiten] Ann Arbor Classification

For lymphoma the TNM-classification does not make sense and therefore theso-called Ann-Arbor classification will be applied.

In this system, the stages I-IV are being distinguished, with an additional suffix letter

  • A meaning "no general symptoms"
  • B "with general symptoms"
  • E "extra-lymphatic organ affected"
  • S "spleen affected"

As with TNM, the Ann-Arbor classification distinguishes between clinical (cS) and pathological (pS) grading.

According to Durie & Salmon tere are gradings from I to III or the grades according to SWOG from 1-4 for the "Multiple Myeloma".

[Bearbeiten] FIGO Stages

FIGO stages ignificantly overlap with the TNM classification, especially on the T-axis.

Therefore no details are being given here.

[Bearbeiten] Gleason Score

The so-called Gleason-Score serves to classify the prostate carcinoma. The total numeric value is the sum of two indicators for • loss of differentiation (1-5) • growth pattern (1-5)

Resulting values range from 2 to 10 (also see Scores & Assessment DSTU).

Furthermore there is a more recent Gleason classification (according to Dhom, Müller and Helpap [Helpap 2002, Helpap2007]), which also requires to specify the procedure (esp. the two degrees) being used.

[Bearbeiten] Papanikolaou

The so-called Pap-Test [Pap] is based on colored cell samples from the cervix and is used as an early indocator for cervical cancers.

[Bearbeiten] WHO Grading

The so-called WHO Grading serves as an individual progonosis on the one hand and also is an indicator towards further treatment on the other hand.

Tumors of WHO Grade I and II in most cases can be treated by surgery alone, while tumors with WHO Grading III and IV normally need additional treatment by radiation or chemotherapie after surgery.

The grading looks like this:

Code Codename Meaning
I benign,slow growth of tumor, very good prognosis
II still benign, slow growth of tumor,tendency to recur
III malignant,actively producing abnormal cells,tends to recur
IV very malignant,fast growth,needs systemic therapy, bad prognosis

Table 9: WHO Grading (OID 1.2.276.0.76.5.394)

The fourth edition of the "World Health Organization (WHO) Classification of tumours of the central nervous system" (2007) lists all relevant tumor entities.

Also see "Brain Tumor Basics" (http://www.abta.org/sitefiles/sitepages/524309b806778d4f7b79044d97f324ea.pdf)

The Implementation Guideline „Arztbrief“ (www.hl7.de) as well as related documents lists various examples of how to represent diagnoses via HL7 V3/CDA Release 2 (see [CDAr2Arztbrief]).

[Bearbeiten] Terminology

[Bearbeiten] Introduction

This chapter separates codes in use from normative specifications, in order to allow updates to such codes without having to rewrite the normative part. Therefore this chapter is just informative. Current codes have to be requested.

Due to pending third-party copy rights regarding some of the the following tables, the textual descriptions may not be given here such that the respective fields remain empty.

[Bearbeiten] Dignity

Dignity refers to a tumor property related to their biological behavior in the body. 13

Meaning Code
0 benign
1 Neoplasm with uncertain or unknown behaviour
2 Carcinoma in situ
3 malign, Primary Tumor
6 malign, Metastasis
9 malign, not differentiated between Primary Tumor or Metastasis

Table 15: Dignity Codes (OID 1.2.276.0.76.5.335)

12 In this case, a cause has to be documented along with the diagnosis – but that is not covered in this implementation guide. It also has to be clarified whether such diagnosis is equal to “suspicious for”. 13 DIMDI www.dimdi.de ICD10GM, ICDO3

3 a) Irregularly large and irregularly shaped glands, usually with abundant stroma, sometimes also stored tightly irregular and indistinct tumor border Unregelmäßig große und unregelmäßig gestaltete Drüsen mit gewöhnlich reichlicherem Stroma, gelegentlich auch dicht gelagert, unregelmäßige und unscharfe Tumorgrenze
b) Papillary or cribriform structures, sometimes in large gang­like formations Papilläre oder kribriforme Strukturen, z.T. in großen gangähnlichen Bildungen
4 "a) Large irregular epithel formations by glandular fusion (""fused glands"") and branched glands with irregular infiltration into the surrounding area " Große unregelmäßige Epithelformationen durch Drüsenverschmelzung („fused glands“) sowie verzweigte Drüsen mit unregelmäßiger Infiltration in die Umgebung
b) Adenocarcinoma with prominent clear cytoplasm similar to clear cell adenocarcinomas of the kidney Adenokarzinom mit ausgeprägt klarem Zytoplasma ähnlich hellzelligen Adenokarzinomen der Niere
5 a) Circumscribed round epithelial clusters with mostly solid and cribriform construction, usually with central necrosis Scharf begrenzte runde Epithelhaufen mit meist solidem und kribriformem Bau, gewöhnlich mit zentraler Nekrose

Documentation by the GleasonSum (Gleason¬Score) as the sum of the two most dominating findings: Uniformly structured tumors: two times the points of above table. Non-uniformly structured tumors: points for the dominating share of findings (so-called primary grading) + points for second-largest share (secondary grading), if punch biopsy show more than two grades, the second component will be based on the most adverse component found.

[Bearbeiten] Ann Arbor Codes

The tumor staging system for lymphomas.

Principal Stages

Code Description
I cancer is located in a single region, usually one lymph node and the surrounding area
II cancer is located in two separate regions, an affected lymph node or organ and a second affected area, and that both affected areas are confined to one side of the diaphragm
III cancer has spread to both sides of the diaphragm, including one organ or area near the lymph nodes or the spleen
IV diffuse or disseminated involvement of one or more extralymphatic organs

Table 33: Ann Arbor (OID 1.2.276.0.76.5.405)

Modifiers for Constitutional Symptoms

Code Description
A absence of constitutional symptoms is denoted by adding an ""A""
B presence of constitutional (B-type) symptoms is denoted by adding a ""B""

Table 34: Ann Arbor constitutional symptoms (OID 1.2.276.0.76.5.416 Attention icon.svg Falsche OID: 1.2.276.0.76.5.416 ist atcgm2013))

Modifiers for Spread of Tumor

Code Description
E disease is ""extranodal"" (not in the lymph nodes) or has spread from lymph nodes to adjacent tissue.
S the disease has spread to the spleen.
X the largest deposit is >10 cm large (""bulky disease""), or the mediastinum is wider than 1/3 of the chest on a chest X-ray.

Results of the so-called Pap-Test

Code Meaning
Pap0 non representative sample
PapI normal cell findings
PapII atypical, benign disorder, infection, metaplasia, atrrophy, bacteria, viruses,
PapIIw insufficient samples
PapIII cell proliferation and atypic cells
PapIIID dysplastic , mostly with HPV infection
PapIIIG moderate/severe dyskaryosis and/or dysplasia
PapIV biopsy sample and histological clarification required
PapIVa carcinoma in situ
PapIVb single certain tumour cells, carcinoma very certain
PapV many certain tumour cells, carcinoma certain, cellular changes suggestive of invasive squamous carcinoma, and cellular changes indicative of adenocarcinoma of the uterine cervix and other invasive cancer.
