Stenosis of anus and rectum

This diagnosis code signifies a narrowing of the anal canal or rectum, which can impede the passage of stool and cause symptoms such as constipation, pain, and difficulty with defecation. This constriction can be congenital, inflammatory, post-surgical, or due to other pathological processes.

Assign this code when documentation clearly indicates a diagnosis of anal or rectal stenosis, stricture, or narrowing. This is appropriate for conditions like anal stricture following hemorrhoidectomy, inflammatory bowel disease-related rectal strictures, or congenital anal stenosis. Supporting documentation should specify the anatomical site (anus or rectum) and the presence of narrowing.

• Differentiate from other anorectal conditions like prolapse or fistula, which have distinct codes.
• If the stenosis is a complication of a surgical procedure, consider an additional code from the T80-T88 series for complications of medical and surgical care, if applicable and documented.
• Ensure the documentation specifies whether the stenosis is of the anus, rectum, or both, as this code covers both locations.
