Ulcerative (chronic) proctitis

This code represents chronic inflammation of the rectum, specifically the innermost lining, characterized by ulcerations. It is a form of inflammatory bowel disease (IBD) affecting only the rectum, without involvement of other parts of the colon.

Use this code for patients diagnosed with long-standing or recurrent inflammation of the rectal mucosa with ulcer formation. Documentation should clearly state "chronic proctitis" or "ulcerative proctitis" and specify that the inflammation is confined to the rectum.

• Differentiate from acute proctitis, which has a separate code.
• Ensure documentation specifies "ulcerative" to distinguish from non-ulcerative forms of proctitis.
• Do not use if the inflammation extends beyond the rectum into the colon; consider codes for ulcerative colitis.
