ICD-10 Code L97.8 – Non-pressure chronic ulcer of other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.8 – Non-pressure chronic ulcer of other part of lower leg
What it is
This code identifies a chronic, non-pressure ulcer on a part of the lower leg other than the ankle, heel, or foot. Use it when the record documents a persistent open sore in that location.
Clinical signs
Typical findings include a visible skin break with delayed healing, drainage, or surrounding tissue changes. Clinical features vary; refer to documentation for the exact site and whether the ulcer is chronic.
When to use this code
Use L97.8 when the provider documents a chronic ulcer of the lower leg and the site is not more specifically classified by another L97 code. It fits wound notes that describe location on the calf or lower leg without pressure-related cause. If the record later specifies a more exact site or depth, code that documented detail instead.
Do not use for
Do not use this code for pressure ulcers, diabetic foot ulcers, or ulcers of the ankle, heel, or foot. Check documentation if the cause or anatomic site is unclear.
Coding tip
Verify laterality, exact location, and whether the ulcer is pressure-related before assigning L97.8.
