ICD-10 Code L97.524 – Non-pressure chronic ulcer of other part of left foot with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.524 – Non-pressure chronic ulcer of other part of left foot with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on another part of the left foot with bone necrosis. Use it when documentation shows a persistent foot wound and dead bone tissue, not a pressure injury.
Clinical signs
Typical findings include an open ulcer on the left foot with exposed or necrotic bone, delayed healing, and surrounding tissue breakdown. Clinical features vary; refer to documentation.
When to use this code
Use L97.524 when the record clearly states a chronic ulcer on the left foot, located in a site other than the heel or midfoot, and documents necrosis of bone. This code fits non-pressure ulcers only. Confirm the exact foot location and laterality in the note before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers of the heel or midfoot, or ulcers without documented bone necrosis. Check documentation if the site or depth is unclear.
Coding tip
Verify both the ulcer location and the presence of bone necrosis, because those details determine whether L97.524 is correct.
