ICD-10 Code K60 – Fissure and fistula of anal and rectal regions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60 – Fissure and fistula of anal and rectal regions
What it is
K60 covers fissures and fistulas involving the anal or rectal area. Use it when the record shows a tear, abnormal tract, or both in this region.
Clinical signs
Typical findings include anal pain, bleeding, discharge, or recurrent drainage. Clinical features vary; refer to documentation for whether the condition is a fissure, fistula, or both.
When to use this code
Use K60 when the provider documents an anal fissure, anorectal fistula, or a related condition in the anal or rectal region. It may also fit follow-up visits if the diagnosis remains active and is still being managed. Check documentation for the exact anatomic site and type.
Do not use for
Do not use this code for hemorrhoids, perianal abscess alone, or other rectal disorders without a documented fissure or fistula. If the note is nonspecific, check documentation.
Coding tip
Code to the most specific documented condition and site; if the record does not distinguish fissure from fistula, confirm the provider’s wording.
