ICD-10 Code K60.519 – Anorectal fistula, simple, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.519 – Anorectal fistula, simple, unspecified
What it is
K60.519 identifies a simple anorectal fistula that is not further specified in the record. Use it when documentation confirms a fistula involving the anorectal region but does not describe a more detailed type or location.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records note persistent drainage, perianal irritation, or a tract connecting the anal canal to nearby skin, but you should code only what is clearly documented.
When to use this code
Use this code when the provider documents an anorectal fistula and describes it as simple, with no additional qualifying detail. It also fits cases where the fistula is present but the note does not identify complexity, exact tract, or other subclassification. Check documentation if the record suggests a different fistula type.
Do not use for
Do not use this code for complex, recurrent, or otherwise specified anorectal fistulas when the documentation supports a more precise code. Do not assign it if the condition is not an anorectal fistula or if the record is unclear; check documentation.
Coding tip
If the surgeon’s note gives more detail than “simple, unspecified,” code the most specific fistula description documented.
