ICD-10 Code L97.315 – Non-pressure chronic ulcer of right ankle with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.315 – Non-pressure chronic ulcer of right ankle with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right ankle that extends into muscle but does not show necrosis. Use it when documentation specifies both the anatomic site and the depth.
Clinical signs
Typical findings include a persistent open wound at the right ankle with visible or documented muscle involvement. Clinical features vary; refer to documentation for depth, laterality, and any mention of necrosis.
When to use this code
Use L97.315 when the provider documents a chronic ulcer of the right ankle and clearly states that muscle is involved. It is appropriate for non-pressure ulcers only, not pressure injuries or acute wounds. Confirm that necrosis is absent in the record.
Do not use for
Do not use this code if the ulcer is on another site, if it is a pressure ulcer, or if necrosis is documented. Check documentation when the depth is unclear or when the wound type is not specified.
Coding tip
Verify laterality, ulcer type, depth, and necrosis status before assigning L97.315.
