Clinical Significance
Type 1 diabetes mellitus with foot ulcer is a serious complication reflecting the convergence of peripheral neuropathy, peripheral vascular disease, and impaired immune function. Diabetic foot ulcers are the leading cause of non-traumatic lower extremity amputations and represent a significant source of morbidity, hospitalization, and healthcare costs. These ulcers require multidisciplinary management including wound care, offloading, vascular assessment, and glycemic optimization.
Documentation Requirements

- ✓The provider should record the ulcer location, size, depth (using the Wagner or University of Texas classification), presence of infection, and exposed structures.
- ✓An additional code from L97 should be assigned to specify the ulcer site and severity.
- ✓Vascular status and neuropathy assessment should be documented.
