Anal fissure

This code represents an anal fissure, which is a small tear or cut in the thin, moist tissue (mucosa) lining the anus. These tears typically occur in the posterior midline and can cause significant pain, especially during and after bowel movements, and may be accompanied by bleeding.

Use this code when documentation clearly indicates a diagnosis of an anal fissure. This diagnosis is typically made based on patient symptoms (pain, bleeding) and physical examination findings. It applies to both acute and chronic presentations of an anal fissure.

• Differentiate from other perianal conditions like hemorrhoids or fistulas, which have distinct codes.
• Ensure documentation specifies "anal fissure" and not just generic "rectal pain" or "anal bleeding."
• Consider sequencing if an underlying condition, such as Crohn's disease, is the cause of the fissure.
