- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Chronic Condition
N82.1 is a billable ICD-10-CM diagnosis code for other female urinary-genital tract fistulae. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 742 through 743, 760 through 761. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 8 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified female genital disorders.

Fistulas
A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Questions About N82.1Overview
What is the ICD-10 code for other female urinary-genital tract fistulae?
The ICD-10-CM code for other female urinary-genital tract fistulae is N82.1 (sometimes written as N821). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is N82.1 (Fistulae involving female genital tract) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other female urinary-genital tract fistulae on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does N82.1 group to?
When other female urinary-genital tract fistulae is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 760, 761, with relative weights from 0.7039 to 1.8448 depending on complications. Higher weights mean higher Medicare reimbursement.
Is N82.1 a CC or MCC?
CMS lists N82.1 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 8 closely related codes in its exclusion list.
Can N82.1 be reported with N32.1?
Not as a rule. The Excludes1 note at N82, which applies to N82.1, lists "vesicointestinal fistulae (N32.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
