Other ulcerative colitis with rectal bleeding

This code signifies a form of ulcerative colitis, not specified as pancolitis, left-sided, or proctitis, that is currently manifesting with rectal bleeding. Ulcerative colitis is a chronic inflammatory bowel disease affecting the large intestine, characterized by inflammation and ulcers. The "other" designation indicates the extent of the disease is not precisely defined by the more specific K51 subcategories but is known to involve bleeding.

Use this code when documentation clearly indicates a diagnosis of ulcerative colitis, the extent of which is not specified as proctitis, left-sided, or pancolitis, and the patient is actively experiencing rectal bleeding. This applies to both initial and subsequent encounters where rectal bleeding is a current symptom of the underlying ulcerative colitis. Supporting documentation would include physician notes detailing the diagnosis of ulcerative colitis and the presence of rectal bleeding.

• Ensure the documentation specifies "other" ulcerative colitis and explicitly mentions current rectal bleeding.
• Do not use this code if the extent of ulcerative colitis (e.g., proctitis, left-sided, pancolitis) is clearly documented; use the more specific K51 subcategories with the .11, .21, or .31 extensions.
• This code is for active bleeding; if the patient has a history of bleeding but is not currently bleeding, a different subclassification (e.g., K51.819 for "other ulcerative colitis with unspecified complications") would be more appropriate.
