Questions About Z95.4Overview
Is Z95.4 (Presence of cardiac and vascular implants and grafts) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report presence of other heart-valve replacement on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does Z95.4 group to?
On inpatient claims, presence of other heart-valve replacement maps to MS-DRG 314, 315, 316, with relative weights from 0.6821 to 2.0852 depending on complications. Higher weights mean higher Medicare reimbursement.
Can Z95.4 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because presence of other heart-valve replacement describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z95.4 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 presence of other heart-valve replacement on inpatient claims.
What is the ICD-9 equivalent of Z95.4?
Under the General Equivalence Mappings, presence of other heart-valve replacement converts to ICD-9-CM V42.2 (heart valve transplant). The mapping is approximate, so confirm the match fits the documentation.
