Other ulcerative colitis without complications

This code signifies a chronic inflammatory bowel disease affecting the colon, characterized by inflammation and ulceration, but without any specified complications. It represents a form of ulcerative colitis that does not fall into other specific categories (e.g., pancolitis, proctosigmoiditis) and has no documented acute complications such as toxic megacolon, hemorrhage, or fistula.

Use this code when the medical record clearly documents a diagnosis of ulcerative colitis that is not specified to a particular anatomical extent and no complications are noted. This applies to patients with ongoing symptoms or those in remission from ulcerative colitis where no specific complications are present or being treated. Documentation should explicitly state "ulcerative colitis, unspecified" or "other ulcerative colitis" without mention of complications.

• Do not use this code if the anatomical extent of the ulcerative colitis (e.g., pancolitis, proctosigmoiditis) is documented; instead, use a more specific K51 subcategory.
• Avoid this code if any complications (e.g., hemorrhage, toxic megacolon, fistula, abscess) are present; select the appropriate K51 code that includes the complication.
• Always review the entire medical record for any mention of complications or specific anatomical involvement before assigning this unspecified code.
