Questions About Z87.731Overview

Is Z87.731 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report personal history of (corrected) tracheoesophageal fistula or atresia on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z87.731 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of (corrected) tracheoesophageal fistula or atresia describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z87.731 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 (corrected) tracheoesophageal fistula or atresia on inpatient claims.
