Ulcerative (chronic) pancolitis with unsp complications

This code signifies a chronic inflammatory bowel disease affecting the entire colon, characterized by ulceration, without further specification of any associated complications. It represents a widespread and persistent inflammation of the large intestine.

Apply this code when documentation confirms ulcerative colitis involving the entire colon (pancolitis) and there is no mention of specific complications such as toxic megacolon, fistula, or stricture. This is appropriate for initial diagnoses or follow-up when complications are absent or not yet identified.

• Only use this code when the documentation explicitly states "pancolitis" and "unspecified complications" or no complications are noted.
• Avoid using this code if any specific complication (e.g., hemorrhage, abscess, fistula) is documented; instead, code the specific complication.
• Ensure the physician's documentation clearly supports the chronic nature and the extent of the disease (pancolitis).
