Coding Tips

- •Avoid using this code if the complication can be determined from clinical documentation.
Clinical Significance
Ulcerative colitis, unspecified, with unspecified complications is the least specific code in the ulcerative colitis category, lacking both anatomic extent and complication type. This code should be a last resort and always triggers provider queries for both the disease extent and the nature of complications, as more precise coding is almost always achievable.
Documentation Requirements
- ✓Confirmed ulcerative colitis diagnosis
- ✓Provider acknowledgment that complications exist
- ✓Documentation of dual provider queries: one for disease extent and one for complication type
- ✓Treatment plan addressing the colitis and complications
- ✓Plan for colonoscopy to determine disease extent if not already performed
