ICD-10 Code K60.30 – Anal fistula, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.30 – Anal fistula, unspecified
What it is
This code identifies an anal fistula when the provider documents the condition but does not specify the tract, cause, or type. It represents an abnormal connection involving the anal region.
Clinical signs
Typical findings include persistent drainage near the anus, local irritation, pain, or recurrent swelling. Clinical features vary; refer to documentation.
When to use this code
Use K60.30 when the record clearly states anal fistula and no further detail is available. It also fits cases where the provider confirms a fistula but does not document whether it is intersphincteric, transsphincteric, or another type.
If the note later specifies a more exact fistula description, code the documented detail instead. Check documentation when the diagnosis is uncertain or when another anorectal condition is recorded.
Do not use for
Do not use this code for anal fissure, abscess, or hemorrhoids. Also avoid it when the chart identifies a specific fistula type that should be coded more precisely.
Coding tip
Code from the provider’s final diagnosis and confirm whether the fistula is unspecified or more specifically described.
