Date of Initial RX Flag
1261 2 NAACCR 2010 12 1444 - 1445
Description
This flag explains why no appropriate value is in the field, Date Initial RX SEER [1260].
 
Formerly Date of Initial RX Flag.
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, unknown if therapy was administered)
11 No proper value is applicable in this context (e.g., therapy was not administered)
12 A proper value is applicable but not known (e.g., therapy was administered and date is unknown)
Blank A valid date value is provided in item Date Initial RX SEER [1260], 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.
