Description
This flag explains why no appropriate value is in the field, Date of Death--Canada [1755]. This data item was first available in Volume II Version 12.

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.)

10	No information whatsoever can be inferred from this exceptional value (e.g, patient is not known to be deceased)
11	No proper value is applicable in this context (e.g. patient is alive)
12	A proper value is applicable but not known (e.g., date of death is unknown)
Blank	A valid date value is provided in item Date of Death--Canada [1755], 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.
