0.000What This Code Means
A form of ulcerative colitis (inflammation of the colon and rectum) with complications that are not specifically identified.
Coding Tips
- •Use this code only when the specific complication is documented but doesn't fit other K51.81x subcategories; query the provider if the complication type is unclear.
- •This code requires documentation of 'other ulcerative colitis' - ensure the extent of disease (left-sided, pancolitis, etc.) is also coded separately if applicable.
Clinical Significance
Other ulcerative colitis with unspecified complications indicates an atypical form of ulcerative colitis with complications whose nature is not documented. This combination of imprecise classifications should trigger queries to the provider for both the disease extent and the complication type to improve coding accuracy.
Documentation Requirements
- ✓Confirmed ulcerative colitis diagnosis
- ✓Documentation explaining why standard anatomic classifications do not apply
- ✓Provider acknowledgment that complications exist
- ✓Provider query for complication specification
- ✓Treatment plan addressing colitis and complications
