ICD-10 Code L97.4 – Non-pressure chronic ulcer of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.4 – Non-pressure chronic ulcer of heel and midfoot
What it is
This code identifies a chronic, non-pressure ulcer located on the heel or midfoot. It describes an open skin lesion caused by factors other than pressure, such as poor circulation or diabetes-related complications.
Clinical signs
You may see a persistent open wound with loss of skin over the heel or midfoot, sometimes with drainage, granulation tissue, or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic ulcer of the heel or midfoot and clearly states it is not a pressure ulcer. It fits outpatient or inpatient records that identify the site but do not specify a more detailed laterality or severity in the available code set. Check documentation if the ulcer depth, laterality, or stage is unclear.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or ulcers on other foot locations. If the record describes only a foot ulcer without heel or midfoot involvement, check documentation.
Coding tip
Match the ulcer site exactly to the provider’s note and confirm it is documented as non-pressure before assigning L97.4.
