ICD-10 Code K60.0 – Acute anal fissure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K60.0 – Acute anal fissure
What it is
K60.0 identifies a recent tear in the lining of the anal canal. It usually causes pain with bowel movements and may be associated with a small amount of bright red bleeding.
Clinical signs
Typical findings include sharp pain during or after defecation, anal spasm, and visible fissure on examination. Clinical features vary; refer to documentation.
When to use this code
Use K60.0 when the provider documents an acute, recent anal fissure or a fissure with short symptom duration. Code it when the record supports a new or clearly nonchronic tear rather than a long-standing condition.
Do not use for
Do not use this code for chronic anal fissure, anal abscess, fistula, or hemorrhoids. If the note does not specify acuity, check documentation.
Coding tip
Confirm the provider’s wording for “acute” versus “chronic” before assigning K60.0.
