R39.2 — Extrarenal uremia
R39.2 is a billable, specific ICD-10-CM code for extrarenal uremia. 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.
- uremia NOS (N19)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Prerenal uremia
Other codes that can never be billed with R39.2
These codes carry an Excludes1 note pointing at R39.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R39.2 alone.
- N19Unspecified kidney failure
Risk adjustment
R39.2 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
R39.2 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A53064Billing and Coding: Outpatient Occupational Therapy
- A57050Billing and Coding: Post-Void Residual Urine and/or Bladder Capacity by Ultrasound
How R39.2 is indexed
