ICD-10 Code L97.926 – Non-pressure chronic ulcer of unspecified part of left lower leg with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.926 – Non-pressure chronic ulcer of unspecified part of left lower leg with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg with bone involvement and no necrosis. Use it when the documentation shows the ulcer reaches bone but does not describe dead tissue.
Clinical signs
Typical findings include a persistent open wound on the left lower leg with exposed or involved bone. Clinical features vary; refer to documentation for depth, location, and whether necrosis is absent.
When to use this code
Use L97.926 when the record clearly documents a chronic ulcer of the unspecified part of the left lower leg and states bone involvement without necrosis. It is appropriate when the provider specifies the laterality, chronicity, and depth. Check documentation if the anatomic site is more precise or if necrosis is mentioned.
Do not use for
Do not use this code for pressure ulcers, ulcers on another limb, or ulcers without bone involvement. If the note describes necrosis or does not confirm the left lower leg site, check documentation.
Coding tip
Match laterality, site, depth, and necrosis status exactly to the provider’s wording before assigning L97.926.
