ICD-10 Code L97.213 – Non-pressure chronic ulcer of right calf with necrosis of muscle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.213 – Non-pressure chronic ulcer of right calf with necrosis of muscle
What it is
This code identifies a chronic ulcer on the right calf that is not caused by pressure and extends to necrosis of muscle. Use it when documentation shows a persistent open wound with muscle tissue death in the right calf.
Clinical signs
Findings typically include a nonhealing ulcer with visible tissue loss, drainage, and surrounding skin changes. Clinical features vary; refer to documentation for the ulcer depth and whether muscle necrosis is specifically confirmed.
When to use this code
Use L97.213 when the record clearly states a chronic, non-pressure ulcer of the right calf and documents necrosis of muscle. It is appropriate for outpatient, inpatient, or wound-care notes when laterality and depth are both specified. If the site or tissue involvement is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another limb or site. Do not assign it if muscle necrosis is not documented or if the ulcer depth is not confirmed.
Coding tip
Verify the exact anatomic site, laterality, and depth in the provider note before assigning L97.213.
