ICD-10 Code L97.426 – Non-pressure chronic ulcer of left heel and midfoot with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.426 – Non-pressure chronic ulcer of left heel and midfoot with bone 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 bone, with no documented necrosis. Use it when the record shows tissue loss from another cause, not a pressure injury.
Clinical signs
Typical findings include a persistent open wound on the left heel or midfoot, exposed or involved bone, and documentation that necrosis is absent. Clinical features vary; refer to documentation.
When to use this code
Use L97.426 when the provider documents a chronic ulcer of the left heel or midfoot with bone involvement and specifically states there is no necrosis. It also fits when the wound is described as non-pressure and chronic, with laterality clearly left. Check documentation if depth or location is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with documented necrosis. If the site is not the left heel or midfoot, choose the code that matches the documented location.
Coding tip
Confirm laterality, ulcer site, depth, and the absence of necrosis in the note before assigning L97.426.
