Ostomy

An ostomy is surgery to create an opening (stoma) from an area inside the body to the outside. It treats certain diseases of the digestive or urinary systems. It can be permanent, when an organ must be removed. It can be temporary, when the organ needs time to heal. The organ could be the small intestine, colon, rectum, or bladder.

Questions About Z93.8Overview

Is Z93.8 (Artificial opening status) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other artificial opening status on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z93.8 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because other artificial opening status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z93.8 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 other artificial opening status on inpatient claims.

What is the ICD-9 equivalent of Z93.8?

Under the General Equivalence Mappings, other artificial opening status converts to ICD-9-CM V44.7 (artificial vagina status) and V44.8 (artif open status NEC). The mapping is approximate, so confirm the match fits the documentation.
