Questions About Z92.83Overview
Is Z92.83 (Personal history of other medical treatment) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of failed moderate sedation on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z92.83 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of failed moderate sedation describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z92.83 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 failed moderate sedation on inpatient claims.
What is the ICD-9 equivalent of Z92.83?
Under the General Equivalence Mappings, personal history of failed moderate sedation converts to ICD-9-CM V15.80 (hx failed mod sedation). The mapping is a direct match.
