ICD-10 Code L97.515 – Non-pressure chronic ulcer of other part of right foot with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.515 – Non-pressure chronic ulcer of other part of right foot with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of the right foot that extends into muscle but shows no necrosis. Use it when the documentation specifies the right foot location and muscle involvement.
Clinical signs
Typical findings include a persistent open wound with tissue loss, exposed or involved muscle, and delayed healing. Clinical features vary; refer to documentation for depth, location, and any mention of necrosis.
When to use this code
Use L97.515 when the provider documents a chronic ulcer on the other part of the right foot, and the depth reaches muscle without necrotic tissue. You should confirm the ulcer is non-pressure and not a different foot site.
This code fits wound notes, podiatry assessments, or specialist records that clearly identify the anatomic site and tissue depth. If the chart only says “foot ulcer” or does not confirm muscle involvement, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers on the heel or other specified foot locations, or ulcers with necrosis. Do not assign it when the record does not support muscle involvement.
Coding tip
Verify the exact right-foot subsite and the deepest documented tissue level before coding.
