Z99.2 — Dependence on renal dialysis
Z99.2 is a billable, specific ICD-10-CM code for dependence on renal dialysis. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- encounter for fitting and adjustment of dialysis catheter (Z49.0-)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- noncompliance with renal dialysis (Z91.15-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Hemodialysis status
- Peritoneal dialysis status
- Presence of arteriovenous shunt for dialysis
- Renal dialysis status NOS
Other codes that can never be billed with Z99.2
These codes carry an Excludes1 note pointing at Z99.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z99.2 alone.
- I77.0Arteriovenous fistula, acquired
Risk adjustment
Z99.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
Z99.2 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How Z99.2 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Z99.2.
