ICD-10 Code K60.513 – Anorectal fistula, simple, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.513 – Anorectal fistula, simple, recurrent
What it is
This code identifies a recurrent, simple fistula involving the anus or rectum. It indicates an abnormal tract between the anorectal area and nearby skin or tissue that has come back after prior treatment.
Clinical signs
Common findings include persistent or recurring drainage, local irritation, pain, or a small opening near the anus. Clinical features vary; refer to documentation for whether the fistula is simple and recurrent.
When to use this code
Use this code when the provider documents a simple anorectal fistula that has recurred after prior resolution or treatment. It fits cases where the anatomy is uncomplicated and no complex branching is described. If the record does not clearly state recurrence, check documentation.
Do not use for
Do not use it for complex, unspecified, or nonrecurrent anorectal fistulas. Also avoid it when the documentation describes a different anal condition, such as abscess without a fistula.
Coding tip
Confirm both “simple” and “recurrent” in the provider note before assigning K60.513.
