Patient EducationClinical

Pacemakers and Implantable Defibrillators

An arrhythmia is any disorder of your heart rate or rhythm. It means that your heart beats too quickly, too slowly, or with an irregular pattern. Most arrhythmias result from problems in the electrical system of the heart. If your arrhythmia is serious, you may need a cardiac pacemaker or an implantable cardioverter defibrillator (ICD).

Questions About Z95.810Overview

Is Z95.810 (Presence of other cardiac implants and grafts) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report presence of automatic (implantable) cardiac defibrillator on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z95.810 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because presence of automatic (implantable) cardiac defibrillator describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z95.810 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 automatic (implantable) cardiac defibrillator on inpatient claims.

What is the ICD-9 equivalent of Z95.810?

Under the General Equivalence Mappings, presence of automatic (implantable) cardiac defibrillator converts to ICD-9-CM V45.02 (status autm crd dfbrltr). The mapping is a direct match.
