ICD-10 Code L97.206 – Non-pressure chronic ulcer of unspecified calf with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.206 – Non-pressure chronic ulcer of unspecified calf with bone involvement without evidence of necrosis
What it is
This code describes a chronic ulcer on the calf that is not caused by pressure and extends to the bone, without signs of tissue death. It applies when the calf site is unspecified and documentation confirms bone involvement.
Clinical signs
Typical findings include a persistent open wound on the calf with depth sufficient to involve bone. Clinical features vary; refer to documentation for laterality, cause, and whether necrosis is absent.
When to use this code
Use L97.206 when the record clearly states a non-pressure chronic ulcer of the calf with bone involvement and no necrosis. You should also use it when the provider documents an ulcer reaching bone but does not specify right or left calf. Check documentation if the site or 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 identifies a different leg site or laterality, code that documented location instead.
Coding tip
Confirm both “bone involvement” and “without evidence of necrosis” before assigning L97.206.
