This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Coding Tips

•Use additional L97 or L98 codes to identify the specific site and severity of the ulcer

Clinical Significance

E13.622 captures other skin ulcers in other specified diabetes mellitus, covering diabetic ulcerations at sites other than the foot. These may include leg ulcers, pressure areas, or other locations where diabetes-impaired healing and vascular supply contribute to chronic wound formation requiring ongoing medical management.

Documentation Requirements

✓Documentation must confirm secondary diabetes, the ulcer location (excluding foot, which uses E13.621), and the diabetic etiology.
✓Wound characteristics and an additional L97 or L98 code specifying the site and severity should be assigned.

Use Additional Code
