ICD-10 Code L97.912 – Non-pressure chronic ulcer of unspecified part of right lower leg with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.912 – Non-pressure chronic ulcer of unspecified part of right lower leg with fat layer exposed
What it is
This code identifies a chronic ulcer on the right lower leg that is not caused by pressure and extends into the fat layer. Use it when documentation specifies the right lower leg but does not name a more exact site.
Clinical signs
You may see an open wound with delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation for confirmation that the ulcer is chronic, non-pressure, and has exposed fat layer.
When to use this code
Use L97.912 when the record clearly states a chronic non-pressure ulcer of the right lower leg and the depth reaches the fat layer. It is appropriate when the exact part of the lower leg is not further specified. Check documentation if the cause, laterality, or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another body site. It is also wrong if the documentation does not confirm fat layer exposure or does not specify the right lower leg.
Coding tip
Confirm chronicity, laterality, and wound depth before assigning the code.
