ICD-10 Code K60.512 – Anorectal fistula, simple, persistent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.512 – Anorectal fistula, simple, persistent
What it is
This code identifies a simple anorectal fistula that remains present over time. It refers to an abnormal tract between the anal canal and nearby skin or tissue, documented as persistent.
Clinical signs
Typical findings include ongoing drainage, local irritation, and a visible or palpable fistulous opening. Clinical features vary; refer to documentation if the record does not clearly describe persistence or simplicity.
When to use this code
Use this code when the provider documents a simple anorectal fistula that is chronic or persistent. It fits cases with continued symptoms or an unchanged fistulous tract over time. You should confirm the note supports both the anorectal location and the persistent nature.
Do not use for
Do not use this code for fistulas that are not anorectal, or when the record describes a complex, recurrent, or postoperative fistula instead. Check documentation if the type or chronicity is unclear.
Coding tip
Code only when the chart explicitly supports both “simple” and “persistent”; otherwise, check documentation.
