Ulcerative (chronic) proctitis with other complication

This code signifies chronic inflammation of the rectum (proctitis) due to ulcerative colitis, specifically when an additional complication beyond simple bleeding or stricture is present. This form of inflammatory bowel disease affects only the rectum and is characterized by continuous mucosal inflammation. The "other complication" indicates a specific adverse event or condition arising from the proctitis that is not otherwise specified by more granular codes.

Apply this code when documentation clearly states ulcerative proctitis with a complication such as toxic megacolon, fistula, abscess, or perforation, and a more specific complication code (e.g., K51.211 for toxic megacolon) is not available or appropriate. Ensure the physician's notes explicitly link the complication to the ulcerative proctitis. This code is appropriate when the complication is not bleeding (K51.212) or stricture (K51.213).

• Always review the medical record for specific details regarding the "other complication" to ensure no more precise code exists.
• Do not use this code if the complication is explicitly documented as hemorrhage or stricture, as dedicated codes exist for those scenarios.
• Sequence this code as the primary diagnosis when the ulcerative proctitis with its complication is the reason for the encounter.
