About N82.4

N82.4 is the ICD-10-CM diagnosis code for other female intestinal-genital tract fistulae. It belongs to category N82 (fistulae involving female genital tract), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N82, choose N82.4 (Other female intestinal-genital tract fistulae) only when documentation doesn't support a more specific option: Vesicovaginal fistula (N82.0), other female urinary-genital tract fistulae (N82.1), fistula of vagina to small intestine (N82.2), fistula of vagina to large intestine (N82.3), female genital tract-skin fistulae (N82.5), other female genital tract fistulae (N82.8) and female genital tract fistula, unspecified (N82.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228), DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 06 (Diseases and Disorders of the Digestive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 619.1 (Digestive-genital tract fistula, female).
