Patient EducationClinical

Fistulas

A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Questions About N82Overview

What is the ICD-10 code for fistulae involving female genital tract?

N82 is the ICD-10-CM category for fistulae involving female genital tract, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N82 (Fistulae involving female genital tract) a billable code?

No. This is a category header that groups the codes for fistulae involving female genital tract, and headers cannot be submitted on claims. Claims for fistulae involving female genital tract need a more specific code from this category, such as N82.0, N82.1, and N82.2.

Can N82 be reported with N32.1?

Not as a rule. The Excludes1 note on N82 lists "vesicointestinal fistulae (N32.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
