0.000What This Code Means
A form of ulcerative colitis affecting areas of the colon other than the left side, with bleeding from the rectum.
Coding Tips
- •Document the presence of rectal bleeding in addition to the ulcerative colitis diagnosis
- •Distinguish from other causes of rectal bleeding to ensure accurate coding
Clinical Significance
Other ulcerative colitis with rectal bleeding captures atypical forms of ulcerative colitis accompanied by hemorrhagic symptoms. The rectal bleeding indicates active disease requiring treatment optimization and monitoring for anemia, while the 'other' classification suggests the anatomic extent does not fit standard subcategories.
Documentation Requirements
- ✓Confirmed ulcerative colitis diagnosis with documented extent that does not fit standard subcategories
- ✓Documentation of rectal bleeding including frequency and severity
- ✓Provider attribution of bleeding to the ulcerative colitis
- ✓Laboratory values if clinically significant bleeding
- ✓Treatment plan for active disease
- ✓Disease activity assessment
