About coding rectovaginal fistula
The ICD-10-CM code for rectovaginal fistula is N82.3 (Fistula of vagina to large intestine). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N82.3.
Within N82 (fistulae involving female genital tract), N82.3 is specifically for fistula of vagina to large intestine. Related codes cover Vesicovaginal fistula (N82.0), other female urinary-genital tract fistulae (N82.1), fistula of vagina to small intestine (N82.2), other female intestinal-genital tract fistulae (N82.4), 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.
