ICD-10 Code K60.413 – Rectal fistula, simple, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.413 – Rectal fistula, simple, recurrent
What it is
This code identifies a recurrent, simple fistula involving the rectum. It indicates an abnormal tract that has returned after prior healing or treatment and is documented as simple rather than complex.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include persistent or recurrent drainage, local irritation, and evidence of a fistulous opening on examination or imaging.
When to use this code
Use K60.413 when the provider documents a rectal fistula that is recurrent and specifically described as simple. Code it when the record supports a return of the same condition after prior resolution. If the note does not clearly identify recurrence or simplicity, check documentation.
Do not use for
Do not use this code for an initial rectal fistula without recurrence, or for a complex fistula. If the documentation describes a different anorectal or perianal fistula, select the more specific code.
Coding tip
Confirm both “simple” and “recurrent” in the provider’s wording before assigning K60.413.
