Questions About Z91.82Overview

Is Z91.82 a billable code?

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

Can Z91.82 be a principal diagnosis?

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

Who can Z91.82 be reported for?

The Medicare Code Editor checks personal history of military deployment against patient demographics: this code is intended for adult patients (age 15 through 124). Claims outside these limits are flagged as inconsistent.

Is Z91.82 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 personal history of military deployment on inpatient claims.

What is the ICD-9 equivalent of Z91.82?

Under the General Equivalence Mappings, personal history of military deployment converts to ICD-9-CM V15.89 (hx-health hazards NEC). The mapping is approximate, so confirm the match fits the documentation.
