Fissure and fistula of anal and rectal regions (K60) ICD-10-CM
The K60 code range covers fissure and fistula of anal and rectal regions with 40 ICD-10-CM diagnosis codes. 30 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K60 range.
Anorectal Fistula
A pathologic tract that connects an opening in the anal canal to the perianal skin. In the vast majority of cases there is a history of perianal abscess.
Fissure in Ano

Rectal Fistula
An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.
About the K60 Code Range
Fissures and fistulas in the anal and rectal regions fall within this group of intestinal diseases.
Anal fissures are separated into acute, chronic, and unspecified codes. Fistulas are grouped by site: K60.3 for anal, K60.4 for rectal, and K60.5 for anorectal. Each site separates simple, complex, and unspecified fistulas. The simple and complex branches then distinguish initial, persistent, recurrent, and unspecified.
