ICD-10 Code L97.525 – Non-pressure chronic ulcer of other part of left foot with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.525 – Non-pressure chronic ulcer of other part of left foot with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of the left foot that extends to muscle, with no necrosis documented. It is used when the wound is not caused by pressure and the left foot location is specified.
Clinical signs
Typical findings include an open, non-healing wound of the left foot with documented muscle involvement. Clinical features vary; refer to documentation for depth, location, and whether necrosis is absent.
When to use this code
Use this code when the record clearly states a chronic ulcer on the left foot, involves muscle, and does not show necrosis. You should also confirm that the site is “other part of left foot,” not heel, midfoot, or toe. If the note is vague, check documentation.
Do not use for
Do not use this code if the ulcer is pressure-related, if necrosis is present, or if the documentation does not confirm muscle involvement. It is also wrong for ulcers on a different left-foot site.
Coding tip
Verify laterality, exact foot location, depth, and absence of necrosis before assigning L97.525.
