ICD-10 Code L97.915 – Non-pressure chronic ulcer of unspecified part of right lower leg with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.915 – Non-pressure chronic ulcer of unspecified part of right lower leg with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right lower leg when the wound extends to muscle but there is no necrosis. Use it for a documented ulcer that is not caused by pressure.
Clinical signs
Typical findings include an open wound on the right lower leg with chronic tissue loss and depth to muscle. Clinical features vary; refer to documentation for laterality, location, depth, and whether necrosis is absent.
When to use this code
Use L97.915 when the record clearly states a non-pressure chronic ulcer of the right lower leg with muscle involvement and no evidence of necrosis. It fits outpatient, inpatient, and wound-care documentation when the site is unspecified within the lower leg. Check documentation if the note does not confirm depth or laterality.
Do not use for
Do not use this code for pressure ulcers, ulcers on another limb, or ulcers with necrosis documented. If the provider describes only skin breakdown or a different depth, select the more accurate code.
Coding tip
Verify that “right lower leg,” “muscle involvement,” and “without necrosis” are all documented before assigning L97.915.
