ICD-10 Code L97.513 – Non-pressure chronic ulcer of other part of right foot with necrosis of muscle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.513 – Non-pressure chronic ulcer of other part of right foot with necrosis of muscle
What it is
This code identifies a chronic, non-pressure ulcer on another part of the right foot with muscle necrosis. Use it when the wound is not caused by pressure and documentation specifies muscle involvement.
Clinical signs
Findings may include a persistent open wound on the right foot with exposed or necrotic muscle tissue. Clinical features vary; refer to documentation for ulcer location, chronicity, and depth.
When to use this code
Use L97.513 when the record clearly states a chronic non-pressure ulcer on the right foot, in a site other than heel or midfoot, and notes necrosis of muscle. It is appropriate when the provider documents ulcer depth and laterality. Check documentation if the anatomic site is unclear.
Do not use for
Do not use this code for pressure ulcers, diabetic ulcers without this specific description, or ulcers on the heel or midfoot. If muscle necrosis is not documented, choose the code that matches the recorded depth.
Coding tip
Confirm the exact right-foot location and tissue depth before assigning this code.
