Ulcerative (chronic) pancolitis with abscess

This code describes a severe form of ulcerative colitis affecting the entire colon (pancolitis) that has progressed to include the formation of an abscess. An abscess is a localized collection of pus, indicating a significant inflammatory and infectious complication of the underlying chronic inflammatory bowel disease.

Use this code when documentation explicitly states ulcerative pancolitis with an associated abscess. This typically occurs in patients with a known history of ulcerative colitis experiencing an acute exacerbation or complication. Supporting documentation should include physician notes detailing the diagnosis of ulcerative pancolitis and the presence of an abscess, often confirmed by imaging studies or endoscopic findings.

• Ensure documentation clearly specifies "pancolitis" and not just "colitis" or "proctitis" to accurately capture the extent of the disease.
• Verify the abscess is a complication of the ulcerative colitis; if it's unrelated, a separate code for the abscess may be more appropriate.
• Do not confuse with Crohn's disease, which has its own distinct codes for abscess formation.
