ICD-10 Code L97.425 – Non-pressure chronic ulcer of left heel and midfoot with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.425 – Non-pressure chronic ulcer of left heel and midfoot with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left heel or midfoot that extends to muscle but shows no necrosis. Use it when documentation specifies both the anatomic site and the depth.
Clinical signs
Typical findings include an open ulcer on the left heel or midfoot with visible or documented muscle involvement. Clinical features vary; refer to documentation for signs of infection, drainage, or surrounding tissue changes.
When to use this code
Use L97.425 when the provider documents a chronic ulcer of the left heel or midfoot with muscle involvement and no evidence of necrosis. It may appear in wound care notes, podiatry records, or problem lists when depth and laterality are clear. If the record does not specify muscle involvement, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers on other left foot sites, or ulcers with necrosis. If the depth is only skin breakdown or fat layer involvement, choose the more specific documented code.
Coding tip
Verify laterality, site, depth, and absence of necrosis before assigning the code.
