ICD-10 Code K60.319 – Anal fistula, simple, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.319 – Anal fistula, simple, unspecified
What it is
This code identifies a simple anal fistula when the record does not specify a more exact location or type. It describes an abnormal tract between the anal canal and nearby skin, without added complexity in documentation.
Clinical signs
Typical findings include persistent drainage near the anus, local irritation, pain, or recurrent swelling. Clinical features vary; refer to documentation for the exact fistula description and whether it is simple.
When to use this code
Use K60.319 when the clinician documents an anal fistula as simple and does not provide a more specific site or subtype. It may also fit when the note confirms a fistula but leaves laterality, complexity, or exact anatomy unspecified. Check documentation if another anorectal condition is also recorded.
Do not use for
Do not use this code for abscess without a documented fistula, or for complex, Crohn’s-related, or other specifically described fistulas. If the record names a more specific anal fistula code, report that code instead.
Coding tip
Code from the provider’s wording; if “simple” is not documented, do not assume it.
