N82 — Fistulae involving female genital tract

Non-billable headerICD-10-CM

N82 is a non-billable header ICD-10-CM code for fistulae involving female genital tract. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

vesicointestinal fistulae (N32.1)

Other codes that can never be billed with N82

These codes carry an Excludes1 note pointing at N82. 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 alone.

N32.2Vesical fistula, not elsewhere classified
N36.0Urethral fistula
K60.4Rectal fistula

Risk adjustment

N82 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.

Code to one of these instead N82

8 child codes. Green means billable.
