N82.1 — Other female urinary-genital tract fistulae
N82.1 is a billable, specific ICD-10-CM code for other female urinary-genital tract fistulae. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Cervicovesical fistula
- Ureterovaginal fistula
- Urethrovaginal fistula
- Uteroureteric fistula
- Uterovesical fistula
Other codes that can never be billed with N82.1
These codes carry an Excludes1 note pointing at N82.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N82.1 alone.
Risk adjustment
N82.1 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
N82.1 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

- A56802Billing and Coding: Urodynamics
