Questions About Z46.2Overview
Is Z46.2 (Encounter for fitting and adjustment of other devices) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report encounter for fitting and adjustment of other devices related to nervous system and special senses on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is Z46.2 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 encounter for fitting and adjustment of other devices related to nervous system and special senses on inpatient claims.
What is the ICD-9 equivalent of Z46.2?
Under the General Equivalence Mappings, encounter for fitting and adjustment of other devices related to nervous system and special senses converts to ICD-9-CM V53.09 (adj nerv syst device NEC). The mapping is approximate, so confirm the match fits the documentation.
