Code Description

ICD-10 N82.2 is a billable code used to indicate a diagnosis of fistula of vagina to small intestine.

Key Diagnostic Point:

A fistula of the vagina to the small intestine is an abnormal connection that forms between the vaginal canal and the small intestine. This condition can arise from various underlying issues, including severe pelvic inflammatory disease, endometriosis, or complications from surgical procedures. In women with endometriosis, the presence of ectopic endometrial tissue can lead to inflammation and scarring, which may contribute to the formation of a fistula. Additionally, female genital prolapse can create pressure and structural changes that predispose to fistula formation. Ovarian disorders, such as cysts or tumors, may also play a role in the development of fistulas by causing adjacent tissue damage. Polyps in the female genital tract can lead to obstruction and subsequent fistula formation if they cause significant tissue changes. Symptoms of a vaginal fistula may include abnormal vaginal discharge, fecal incontinence, and recurrent urinary tract infections. Diagnosis typically involves a thorough clinical examination, imaging studies, and sometimes endoscopic evaluation to assess the extent of the fistula and any associated complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between types of fistulas (e.g., vaginal vs. rectovaginal)
  • Understanding the underlying causes such as endometriosis and pelvic inflammatory disease
  • Documentation of associated conditions like ovarian disorders or polyps
  • Need for detailed surgical history and previous treatments

Audit Risk Factors

  • Inadequate documentation of the fistula's origin
  • Failure to document associated conditions like endometriosis or pelvic inflammatory disease
  • Misclassification of the type of fistula
  • Lack of imaging studies to support the diagnosis
