Questions About Z97.4Overview

Is Z97.4 (Presence of other devices) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report presence of external hearing-aid on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z97.4 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because presence of external hearing-aid describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z97.4 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 presence of external hearing-aid on inpatient claims.

What is the ICD-9 equivalent of Z97.4?

Under the General Equivalence Mappings, presence of external hearing-aid converts to ICD-9-CM V45.89 (post-proc states NEC). The mapping is approximate, so confirm the match fits the documentation.
