Questions About Z91.412Overview
Is Z91.412 (Personal history of adult abuse) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of adult neglect on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z91.412 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of adult neglect describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Who can Z91.412 be reported for?
The Medicare Code Editor checks personal history of adult neglect against patient demographics: this code is intended for adult patients (age 15 through 124). Claims outside these limits are flagged as inconsistent.
Is Z91.412 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 adult neglect on inpatient claims.
What is the ICD-9 equivalent of Z91.412?
Under the General Equivalence Mappings, personal history of adult neglect converts to ICD-9-CM V15.42 (hx of emotional abuse). The mapping is approximate, so confirm the match fits the documentation.
