Description
This data item records whether there was an inpatient admission for the most definitive therapy, or in the absence of therapy, for diagnostic evaluation. This data item was first available in Volume IIVersion 12 (effective January 2010).

Rationale
Before Version 12 (through 2009 diagnosis), date fields included information in addition to dates. This data item incorporates the non-date meanings for the Date of Inpatient Adm [590] and Date of Inpatient Disch [600] in order to retain the non-date information with the transition to interoperable dates.

Codes

0	Patient was never an inpatient
1	Patient was inpatient
9	Unknown if patient was an inpatient (only used for consolidated cases)
Blank	Not collected
Comment: This is part of the initiative of the transformation from the old NAACCR date standards to interoperable dates.
