ICD-10 Code L97.801 – Non-pressure chronic ulcer of other part of unspecified lower leg limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.801 – Non-pressure chronic ulcer of other part of unspecified lower leg limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on another part of an unspecified lower leg, with skin breakdown only. It means the wound is limited to the skin layer and is not described as involving deeper tissue.
Clinical signs
Expect an open sore or skin loss on the lower leg that persists over time and is not caused by pressure. Clinical features vary; refer to documentation for laterality, exact site, and whether deeper structures are involved.
When to use this code
Use this code when the record documents a chronic ulcer on the lower leg, specifies a non-pressure cause, and states breakdown of skin only. Choose it when the location is “other part” and the lower leg is not further specified. Check documentation if laterality or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers extending beyond skin breakdown. If the chart identifies a more specific lower-leg site, laterality, or deeper tissue involvement, code that documentation instead.
Coding tip
Confirm the ulcer’s cause, exact location, and depth before assigning L97.801.
