Description
This flag explains why no appropriate value is in the field, Date of Birth [240]. This data item was first available in Volume IIVersion 12 (effective January 2010).

Rationale
Before Version 12 (through 2009 diagnosis), date fields included codes that provided information other than dates. As part of an initiative to standardize date fields, new fields were introduced to accommodate non-date information that had previously been transmitted in date fields.

Codes (See Appendix H for the complete Flavors of Null table, which includes the NAACCR codes, HL7 codes and definitions.Use code 12 when date of birth is unknown.)

12	A proper value is applicable but not known (i.e., birth date is unknown)
Blank	A valid date value is provided in item Date of Birth [240], or the date was not expected to have been transmitted
Comment: This is part of the initiative of the transformation from the old NAACCR date standards to interoperable dates.
