ICD-10 Code L97.826 – Non-pressure chronic ulcer of other part of left lower leg with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.826 – Non-pressure chronic ulcer of other 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, in a location other than the specific ankle or calf sites named elsewhere, with bone involvement and no documented necrosis.
Clinical signs
Typical findings include a persistent open wound on the left lower leg that extends to or exposes bone. 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 other part of the left lower leg and documents bone involvement. The ulcer must be non-pressure and not described as having necrotic tissue. Confirm laterality and site before assigning the code.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers on a different lower-leg site. Check documentation if necrosis, laterality, or ulcer depth is unclear.
Coding tip
Verify the exact anatomic site and the phrase “without evidence of necrosis” in the provider note before coding.
