Questions About Z86.39Overview

Is Z86.39 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report personal history of other endocrine, nutritional and metabolic disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z86.39 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of other endocrine, nutritional and metabolic disease describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z86.39 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 other endocrine, nutritional and metabolic disease on inpatient claims.

What is the ICD-9 equivalent of Z86.39?

Under the General Equivalence Mappings, personal history of other endocrine, nutritional and metabolic disease converts to ICD-9-CM V12.1 (hx-nutrition deficiency) and V12.29 (hx-endocr/meta/immun dis). The mapping is approximate, so confirm the match fits the documentation.
