ICD-10 code for Rectouterine fistula

The ICD-10-CM code for Rectouterine fistula is N82.4 (Other female intestinal-genital tract fistulae). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N82.4.

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.
