ICD-10 Code L97.412 – Non-pressure chronic ulcer of right heel and midfoot with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.412 – Non-pressure chronic ulcer of right heel and midfoot with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the right heel or midfoot with exposed subcutaneous fat. It is used when the wound is not caused by pressure injury and the fat layer is visible.
Clinical signs
You may see an open wound at the right heel or midfoot with a chronic course and tissue loss extending through the skin into subcutaneous fat. Clinical features vary; refer to documentation.
When to use this code
Use L97.412 when the record clearly states a chronic ulcer of the right heel or midfoot and documents fat layer exposure. The ulcer must be non-pressure in origin. Choose this code only when laterality, site, and depth are all specified.
Do not use for
Do not use this code for pressure ulcers, ulcers of another foot location, or wounds without documented fat layer exposure. If the chart does not confirm chronicity or laterality, check documentation.
Coding tip
Verify the ulcer site, right-sided laterality, and depth before assigning L97.412.
