Mapping of ICD-10-coded Diagnoses into HL7 v3

Representation of Diagnosis Confidence

Structured representations of ICD10-encoded diagnoses must support primary and secondary codes, code extensions, side localizations and confidence. 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:

Representation of Cancer Diagnosis

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.

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.

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).

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

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.

Qualifier of Tumor Formular

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.

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.

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 then 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, thisexclusion ("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".

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-Faktor (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 Classifikation after initial multi-modal Therapy

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 cliniclal (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".

FIGO Stages

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

Therefore no details are being given here.

Terminology

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.

Codes for TNM-Classification

The TNM classification according to UICC is being a codesystem as a whole. Therefore all tables share the same OID for documentation purposes. An easy way to handle this is the definition of value sets, each with the respective permitted values. Each code may only be used in some documentation if the respective UICC edition is checkmarked in our table– which states that the respective code is a part of that edition .

Tumors

This section lists known T-Categories ref. 17 (without representing possible extensions). Descriptions vary with the related entity. Codes shall be used along with tumor diagnosis, as one code may have different meanings. (e.g. T1 may refer to 23 cm or 24 cm).

Codes for Gleason Score

The Gleason Grading system helps evaluating the prognosis of men with prostate cancer, as a part of a strategy of prostate cancer staging which predicts prognosis and guides therapy. The Gleason score is based on microscopic findings.

Code	Description	German
1	Round to oval equal individual glands, lying close to each other, sharply demarcated from the surrounding area	Runde bis ovale gleich große Einzeldrüsen, dicht nebeneinander liegend, scharf gegen die Umgebung abgegrenzt
2	Slightly less uniform single glands, separated by small amounts of stroma, less sharply defined tumor margin	Etwas weniger uniforme Einzeldrüsen, getrennt durch geringe Mengen von Stroma, weniger scharf begrenzter Tumorrand
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 Epithelformationen 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
	(comedo carcinoma­like)	(komedo­karzinomähnlich)
	b) Irregularly shaped formations of an undifferentiated carcinoma, which only just discernible glandular formation or is identified vacuoles (signet ring­like) than adenocarcinoma	Unregelmäßig begrenzte Formationen eines undifferenzierten Karzinoms, das nur durch gerade noch erkennbare Drüsenbildung oder Vakuolen (siegelringähnlich) als Adenokarzinom zu identifizieren ist

Table 31: Loss of Differentiation according to Gleason Score ref. 19 (OID 1.2.276.0.76.5.402)

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.

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)

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.

Papanicolaou Coding

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.
