ICD-10 Code L97.825 – Non-pressure chronic ulcer of other part of left lower leg with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.825 – Non-pressure chronic ulcer of other part of left lower leg with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of the left lower leg that extends into muscle, with no evidence of necrosis. Use it when the documentation clearly describes depth and laterality.
Clinical signs
Typical findings include a persistent open wound on the left lower leg with exposed or involved muscle tissue. Clinical features vary; refer to documentation for ulcer chronicity, location, and absence of necrosis.
When to use this code
Use L97.825 when the record states a chronic ulcer of the left lower leg, specifies another part of the lower leg, and confirms muscle involvement. The note should also indicate there is no necrotic tissue. If the depth, location, or laterality is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers without muscle involvement, or ulcers with necrosis. If the site is not the left lower leg or the documentation is incomplete, choose a different code or check documentation.
Coding tip
Verify laterality, ulcer depth, and the phrase “without evidence of necrosis” before assigning L97.825.
