ICD-10 Code L97.222 – Non-pressure chronic ulcer of left calf with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.222 – Non-pressure chronic ulcer of left calf with fat layer exposed
What it is
This code identifies a chronic ulcer on the left calf that is not caused by pressure and extends through the skin into the fat layer. Use it when documentation specifies the left calf and exposed subcutaneous tissue.
Clinical signs
Typical findings include an open, non-healing wound on the left calf with visible fat tissue. Clinical features vary; refer to documentation for laterality, depth, and whether pressure injury is excluded.
When to use this code
Use L97.222 when the record clearly states a chronic non-pressure ulcer of the left calf with fat layer exposed. It is appropriate when the provider documents ulcer depth and location, and the wound is not described as a pressure ulcer. Check documentation if the site is ambiguous or the depth is not specified.
Do not use for
Do not use this code for pressure ulcers, superficial ulcers, or ulcers with bone, muscle, or tendon exposure. If the chart does not confirm left calf involvement or chronicity, check documentation.
Coding tip
Verify both laterality and ulcer depth before assigning this code.
