Level/ Type	Code	Kurzbezeichnung	Beschreibung
0-S	NI	(en-US) NoInformation	Description:The value is exceptional (missing, omitted, incomplete, improper). No information as to the reason for being an exceptional value is provided. This is the most general exceptional value. It is also the default exceptional value.
1-S	INV	(en-US) invalid	Description:The value as represented in the instance is not a member of the set of permitted data values in the constrained value domain of a variable.
2-L	DER	(en-US) derived	Description:An actual value may exist, but it must be derived from the provided information (usually an EXPR generic data type extension will be used to convey the derivation expressionexpression .
2-S	OTH	(en-US) other	Description:The actual value is not a member of the set of permitted data values in the constrained value domain of a variable. (e.g., concept not provided by required code system).
3-L	NINF	(en-US) negative infinity	Negative infinity of numbers.
3-L	PINF	(en-US) positive infinity	Positive infinity of numbers.
2-L	UNC	(en-US) un-encoded	Definition: The actual value has not yet been encoded within the approved valueset for the domain. Example: Original text or a local code has been specified but translation or encoding to the approved valueset has not yet occurred. Usage Notes: If it is known that it is not possible to encode the concept, OTH should be used instead.
1-L	MSK	(en-US) masked	There is information on this item available but it has not been provided by the sender due to security, privacy or other reasons. There may be an alternate mechanism for gaining access to this information. Note: using this null flavor does provide information that may be a breach of confidentiality, even though no detail data is provided. Its primary purpose is for those circumstances where it is necessary to inform the receiver that the information does exist without providing any detail.
1-L	NA	(en-US) not applicable	Known to have no proper value (e.g., last menstrual period for a male).
1-S	UNK	(en-US) unknown	A proper value is applicable, but not known.
2-S	ASKU	(en-US) asked but unknown	Information was sought but not found (e.g., patient was asked but didn't know)
3-L	NAV	(en-US) temporarily unavailable	Information is not available at this time but it is expected that it will be available later.
2-L	NASK	(en-US) not asked	This information has not been sought (e.g., patient was not asked)
2-L	QS	(en-US) Sufficient Quantity	Description:The specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material. e.g. 'Add 10mg of ingredient X, 50mg of ingredient Y, and sufficient quantity of water to 100mL.' The null flavor would be used to express the quantity of water.
2-L	TRC	(en-US) trace	The content is greater than zero, but too small to be quantified.
