What This Code Means

A long-lasting, non-pressure-related wound on the thigh with a severity level that does not fit into the standard categories.

Coding Tips

•Use this code only when the ulcer severity is documented but does not match codes L97.101-L97.106
•Document the specific severity characteristics in the medical record to justify use of this code

Clinical Significance

A non-pressure chronic ulcer of the unspecified thigh with other specified severity captures non-healing wounds where the depth is either atypical or not fully characterized. These codes should prompt providers to better document wound depth for more specific coding. Under V28, this maps to HCC 383 (Severe Skin Burn or Condition) with a RAF of 0.517, and under V24 to HCC 161 (Chronic Ulcer of Skin, Except Pressure) with a RAF of 0.426.

Documentation Requirements

✓Exact anatomical location with laterality (right, left, or bilateral thigh)
✓Etiology of the ulcer (venous insufficiency, peripheral arterial disease, neuropathic, post-traumatic)
✓Wound dimensions: length x width x depth in centimeters
✓Wound bed description and depth of tissue involvement
✓Reason severity is 'other specified' — describe the unique characteristics if applicable
✓Chronicity documentation with duration of wound
✓Current wound care plan
✓Vascular assessment results if applicable
✓Contributing comorbidities (diabetes mellitus, peripheral vascular disease)

Commonly Confused Codes

L97.118 — Non-pressure chronic ulcer of right thigh, same severity; assign when laterality is documented as right L97.128 — Non-pressure chronic ulcer of left thigh, same severity; assign when laterality is documented as left L89.894 — Pressure ulcer of other site requires pressure as the etiology, not vascular or other causes L97.9xx — Non-pressure chronic ulcer of unspecified site should not be used for thigh when thigh is documented
