ICD-10 Code L97.401 – Non-pressure chronic ulcer of unspecified heel and midfoot limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.401 – Non-pressure chronic ulcer of unspecified heel and midfoot limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on the heel or midfoot when laterality is not specified and the skin breakdown is limited to the skin surface. Use it for a wound that is not caused by pressure injury.
Clinical signs
Typical findings include an open sore on the heel or midfoot with superficial skin loss and delayed healing. Clinical features vary; refer to documentation for depth, location, and whether the ulcer is truly non-pressure.
When to use this code
Use L97.401 when the record documents a chronic ulcer of the heel or midfoot, laterality is not stated, and the wound is limited to breakdown of skin. Choose this code only when the provider describes a non-pressure ulcer and does not specify a more detailed site or laterality. Check documentation if the note is unclear about depth or cause.
Do not use for
Do not use this code for pressure ulcers, arterial or diabetic foot ulcers unless the provider documents them as non-pressure chronic ulcers. It is also wrong when the ulcer extends beyond skin breakdown or a more specific heel or midfoot code is available.
Coding tip
Verify both the ulcer type and the documented depth before assigning L97.401.
