Angioplasty

Angioplasty is a procedure to improve blood flow in coronary arteries that have become narrow or blocked. Your coronary arteries supply oxygen-rich blood to your heart. If you have coronary artery disease, a sticky material called plaque builds up in your coronary arteries.

Questions About Z98.61Overview

Is Z98.61 (Angioplasty status) a billable code?

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

Can Z98.61 be a principal diagnosis?

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

Is Z98.61 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 coronary angioplasty status on inpatient claims.

What is the ICD-9 equivalent of Z98.61?

Under the General Equivalence Mappings, coronary angioplasty status converts to ICD-9-CM V45.82 (status-post ptca). The mapping is approximate, so confirm the match fits the documentation.
