ICD-10 Code L97.125 – Non-pressure chronic ulcer of left thigh with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.125 – Non-pressure chronic ulcer of left thigh with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left thigh that extends into muscle but shows no necrosis. Use it when the documentation specifies both the site and the depth.
Clinical signs
Typical findings include a persistent open wound on the left thigh with tissue loss reaching muscle. Clinical features vary; refer to documentation for evidence of chronicity and absence of necrotic tissue.
When to use this code
Use L97.125 when the record clearly states a chronic ulcer of the left thigh with muscle involvement and no necrosis. You should also confirm that it is not a pressure injury and that the location is documented as left thigh. If depth or laterality is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without muscle involvement. It is also incorrect if necrosis is present or if the ulcer site is not the left thigh.
Coding tip
Match the ulcer site, depth, and necrosis status exactly to the provider’s note before coding.
