ICD-10 code for genital tract female fistula

The ICD-10-CM code for genital tract female fistula is N82.9 (Female genital tract fistula, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N82.9.

Within N82, choose N82.9 (Female genital tract fistula, unspecified) 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), other female intestinal-genital tract fistulae (N82.4), female genital tract-skin fistulae (N82.5) and other female genital tract fistulae (N82.8).

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 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
