Patient EducationClinical

Dialysis

When your kidneys are healthy, they clean your blood. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, you need treatment to replace the work your kidneys used to do. Unless you have a kidney transplant, you will need a treatment called dialysis.

Questions About Z99.2Overview

Is Z99.2 a billable code?

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

Can Z99.2 be a principal diagnosis?

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

Is Z99.2 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 dependence on renal dialysis on inpatient claims.

What is the ICD-9 equivalent of Z99.2?

Under the General Equivalence Mappings, dependence on renal dialysis converts to ICD-9-CM V45.11 (renal dialysis status). The mapping is a direct match.
