ICD-10 Code L97.115 – Non-pressure chronic ulcer of right thigh with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.115 – Non-pressure chronic ulcer of right thigh with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right thigh that extends into muscle but shows no necrosis. Use it when the documentation specifies both the anatomic site and the depth of tissue involvement.
Clinical signs
Look for a persistent open wound on the right thigh with exposed or involved muscle tissue and no documented dead tissue. Clinical features vary; refer to documentation.
When to use this code
Use L97.115 when the provider documents a chronic ulcer of the right thigh with muscle involvement and explicitly states there is no necrosis. It is appropriate for non-pressure ulcers only, not pressure injuries. If the note does not confirm laterality, depth, or absence of necrosis, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers on another site, or ulcers limited to skin or subcutaneous tissue. Do not assign it if necrosis is documented instead of, or in addition to, the stated finding.
Coding tip
Verify three elements in the note: right thigh, muscle involvement, and no necrosis.
