Ulcerative (chronic) proctitis without complications

This code signifies a chronic inflammatory condition affecting the rectum, characterized by ulcerations, without any associated complications such as strictures, fistulas, or abscesses. It represents a localized form of ulcerative colitis confined to the rectum.

Apply this code when documentation explicitly states "ulcerative proctitis" or "chronic proctitis" and there is no mention of complications. This diagnosis is typically made via colonoscopy with biopsy confirming chronic inflammation and ulceration limited to the rectal mucosa.

• Ensure documentation specifically excludes complications; otherwise, a more specific code for ulcerative proctitis with complications should be used.
• Distinguish from proctitis due to other causes (e.g., infectious, radiation-induced) which have different codes.
• Do not use if the inflammation extends beyond the rectum into the sigmoid colon; this would indicate ulcerative colitis of a different extent.
