ICD-10 Code L97.225 – Non-pressure chronic ulcer of left calf with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.225 – Non-pressure chronic ulcer of left calf with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left calf that extends into muscle tissue but shows no necrosis. Use it when documentation specifies both the left calf location and muscle involvement.
Clinical signs
Expect an open ulcer on the left calf with depth reaching muscle, while the record states no necrotic tissue. Clinical features vary; refer to documentation.
When to use this code
Use L97.225 when the provider documents a chronic left calf ulcer and confirms muscle involvement without necrosis. It applies to non-pressure ulcers, not pressure injuries. Verify laterality, site, and depth in the note before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers without muscle involvement, or ulcers with necrosis. Check documentation if the site is not the left calf or the depth is unclear.
Coding tip
Code the deepest documented tissue level and confirm that “without necrosis” is explicitly stated.
