2026 ICD-10-CM Diagnosis Code L97.815 – Non-pressure chronic ulcer of other part of right 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 right lower leg that extends to muscle, with no necrosis. Use it when the documentation specifies both the right-sided location and muscle involvement.
Clinical signs
Typical findings include an open, non-healing wound on the right lower leg with visible depth to muscle tissue. Clinical features vary; refer to documentation for ulcer chronicity, location, and whether necrosis is absent.
When to use this code
Use this code when the provider documents a chronic ulcer of the right lower leg outside the ankle or foot, and states that muscle is involved. It also requires documentation that there is no evidence of necrosis. If the record does not clearly identify depth or site, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers of the ankle or foot, or ulcers with necrosis. If the wound depth is limited to skin or fat only, select the more specific code supported by the record.
Coding tip
Verify the exact anatomic site and tissue depth before assigning L97.815.
