ICD-10 Code L97.526 – Non-pressure chronic ulcer of other part of left foot with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.526 – Non-pressure chronic ulcer of other part of left foot with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of the left foot that extends to bone. It applies when documentation states there is bone involvement and no evidence of necrosis.
Clinical signs
Typical findings include a persistent open wound on the left foot with exposed or affected bone, often confirmed in the record by imaging or clinical assessment. Clinical features vary; refer to documentation.
When to use this code
Use L97.526 when the provider documents a chronic ulcer on the left foot, specifies a location other than heel or midfoot, and notes bone involvement without necrosis. This code fits long-standing diabetic or vascular-related ulcers only when the ulcer type and extent are clearly documented. Check documentation if the site or tissue depth is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with necrosis. If the chart does not confirm the left-foot site or bone involvement, choose a more specific documented code.
Coding tip
Verify the exact foot location and whether bone is involved before assigning the code.
