ICD-10 Code L97.212 – Non-pressure chronic ulcer of right calf with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.212 – Non-pressure chronic ulcer of right calf with fat layer exposed
What it is
This code describes a chronic ulcer on the right calf caused by factors other than pressure, with the fat layer visible. Use it when the wound is full-thickness and documented on the right lower leg below the knee.
Clinical signs
Typical findings include a persistent open wound with tissue loss, drainage, and visible subcutaneous fat. Clinical features vary; refer to documentation for laterality, depth, and whether the ulcer is truly non-pressure.
When to use this code
Use L97.212 when the record clearly states a chronic ulcer on the right calf and specifies exposure of fat layer. It is appropriate when the ulcer is non-pressure and not described as limited to skin breakdown only. If the note does not confirm depth or location, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, venous stasis ulcers without the required documentation, or wounds on another right leg site. Do not assign it if the ulcer depth is not documented as fat layer exposed.
Coding tip
Confirm both the exact site and the ulcer depth in the provider note before assigning L97.212.
