Questions About Z63.31Overview

Is Z63.31 (Absence of family member) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report absence of family member due to military deployment on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z63.31 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because absence of family member due to military deployment describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z63.31 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for absence of family member due to military deployment on inpatient claims.

What is the ICD-9 equivalent of Z63.31?

Under the General Equivalence Mappings, absence of family member due to military deployment converts to ICD-9-CM V61.8 (family circumstances NEC). The mapping is approximate, so confirm the match fits the documentation.
