ICD-10 Code L97.226 – Non-pressure chronic ulcer of left calf with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.226 – Non-pressure chronic ulcer of left calf with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left calf that extends to bone, with no documented necrosis. Use it when the record clearly links the ulcer site, depth, and laterality.
Clinical signs
Expect an open, non-healing wound on the left calf with evidence that bone is involved. Clinical features vary; refer to documentation for depth, drainage, surrounding tissue changes, and whether necrosis is absent.
When to use this code
Use this code when the provider documents a chronic ulcer of the left calf and states that bone is involved, but necrosis is not present. It fits pressure-free ulcers from vascular, diabetic, or other causes only if the note supports this exact description. Check documentation if the laterality or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers of a different leg site, or ulcers with necrosis documented. If bone involvement is not confirmed, select a less specific ulcer code.
Coding tip
Verify both laterality and depth in the note, because L97.226 requires left calf involvement and bone extension without necrosis.
