ICD-10 Code L97.925 – Non-pressure chronic ulcer of unspecified part of left lower leg with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.925 – Non-pressure chronic ulcer of unspecified part of left lower leg with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg with muscle involvement and no evidence of necrosis. It is used when the documentation specifies the left lower leg but not a more exact site.
Clinical signs
Typical findings include an open ulcer in the left lower leg with depth extending to muscle. Clinical features vary; refer to documentation for evidence that necrosis is absent and that the ulcer is chronic.
When to use this code
Use this code when the record clearly states a non-pressure chronic ulcer of the left lower leg and notes muscle involvement without necrosis. It fits wound descriptions that identify laterality and depth but do not specify a more precise lower-leg location. Check documentation if the site is unclear.
Do not use for
Do not use it for pressure ulcers, acute wounds, or ulcers with documented necrosis. Do not assign it if the chart identifies a more specific lower-leg site or does not confirm muscle involvement.
Coding tip
Confirm laterality, chronicity, depth, and absence of necrosis in the provider note before assigning L97.925.
