ICD-10 Code L97.812 – Non-pressure chronic ulcer of other part of right lower leg with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.812 – Non-pressure chronic ulcer of other part of right lower leg with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the right lower leg, in a location other than the ankle or calf, with fat layer exposure. Use it when the wound is not caused by pressure and reaches subcutaneous tissue.
Clinical signs
Typical findings include a persistent open sore on the right lower leg with visible subcutaneous fat or documentation that the fat layer is exposed. Clinical features vary; refer to documentation.
When to use this code
Use L97.812 when the record clearly states a chronic ulcer on the right lower leg at another specified site and the ulcer extends to the fat layer. You should also confirm that the ulcer is non-pressure and right-sided. If the site or depth is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers of the ankle or calf, or ulcers on the left lower leg. If the depth is not documented as fat layer exposed, choose the more appropriate code based on the record.
Coding tip
Verify laterality, exact lower-leg location, ulcer type, and depth before assigning L97.812.
