0.000What This Code Means
A long-lasting open sore on the right heel or middle part of the foot that is not caused by pressure, with damage limited to the outer layer of skin.
Coding Tips
- •This represents the least severe stage of non-pressure ulcers; confirm the ulcer has not progressed to deeper tissue involvement
- •Document the laterality (right side) clearly in the medical record to support this specific code selection
Clinical Significance
This represents the earliest stage of non-pressure chronic ulceration, limited to epidermal/dermal disruption. While the least severe classification, it still indicates a chronic wound requiring ongoing management and signals potential for progression to deeper tissue involvement. Accurate laterality documentation (right heel and midfoot) is essential for proper code assignment and tracking wound progression over time.
Documentation Requirements
- ✓Specific anatomic location documented as right heel and midfoot
- ✓Confirmation that the ulcer is non-pressure in etiology (not caused by pressure/immobility)
- ✓Chronicity established — ulcer present for extended duration or described as chronic
- ✓Current wound assessment including size (length x width x depth in centimeters)
- ✓Documentation that ulcer is limited to skin breakdown without deeper tissue involvement
- ✓Wound bed description confirming no exposed subcutaneous tissue, muscle, or bone
- ✓Underlying etiology or contributing factors (diabetes, peripheral vascular disease, venous insufficiency)
- ✓Current treatment plan including wound care regimen
Commonly Confused Codes
L97.412 — Fat layer exposed at same location; use when ulcer has progressed beyond skin to expose subcutaneous fatL97.419 — Unspecified severity at same location; skin breakdown is more specific and preferred when documentedL89.0xx (Pressure ulcer of elbow) / L89.6xx (Pressure ulcer of heel) — Pressure ulcers use the L89 category; L97 is specifically for NON-pressure chronic ulcersL97.421 — Same severity but LEFT side; verify laterality matches documentationE11.621 (Type 2 diabetes mellitus with foot ulcer) — If ulcer is due to diabetes, code the diabetic complication first and the L97 code as an additional code to specify site and severity
