0.000What This Code Means
A long-lasting open sore on the left thigh that is not caused by pressure, but the severity level is not specified in the documentation.
Coding Tips
- •This is a default code when severity cannot be determined; query the provider for more specific wound assessment details
- •Avoid using this code if any severity information is documented; select the most specific code available
Clinical Significance
Non-pressure chronic ulcers of the lower extremity are significant indicators of underlying vascular disease, diabetes, or other systemic conditions that impair wound healing. While the severity is unspecified, the presence of any chronic non-pressure ulcer at this site is clinically meaningful and should prompt query for specificity to ensure accurate severity capture.
Documentation Requirements
- ✓Ulcer site documented as left thigh with clear laterality (left side)
- ✓Confirmation that the ulcer is chronic (present for extended duration, not acute)
- ✓Etiology documented as non-pressure (e.g., venous stasis, arterial insufficiency, diabetic, or other non-pressure cause)
- ✓Clinical assessment of wound depth and tissue involvement
- ✓Query provider for specific depth and tissue involvement to improve code specificity
- ✓Document why severity could not be determined if assessment was limited
Commonly Confused Codes
L97.121 — limited to breakdown of skin; skin breakdown only — no deeper tissue involvementL97.128 — other specified severity; severity documented but not fitting standard categoriesL97.229 — right thigh; verify laterality before selecting codeL89.- — Pressure ulcer codes; use only when ulcer is caused by sustained pressure, not vascular or other non-pressure etiology
