ICD-10 Code L97.126 – Non-pressure chronic ulcer of left thigh with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.126 – Non-pressure chronic ulcer of left thigh with bone involvement without evidence of necrosis
What it is
This code identifies a chronic non-pressure ulcer on the left thigh that extends to bone, with no documented necrosis. Use it when the record clearly shows bone involvement and the ulcer is not caused by pressure.
Clinical signs
Typical findings include a persistent open wound on the left thigh with exposed or involved bone. Clinical features vary; refer to documentation, and confirm that necrosis is specifically absent.
When to use this code
Use L97.126 when the provider documents a chronic ulcer of the left thigh and states that bone is involved. The note should also support that the ulcer is non-pressure related and that there is no necrotic tissue. If laterality, depth, or tissue involvement is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with documented necrosis. If the site is not the left thigh, or the record does not confirm chronicity, choose a different code.
Coding tip
Verify three elements in the chart: left thigh location, bone involvement, and absence of necrosis.
