ICD-10 Code L97.822 – Non-pressure chronic ulcer of other part of left lower leg with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.822 – Non-pressure chronic ulcer of other part of left lower leg with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg, located in a site other than the calf or ankle, with exposed subcutaneous fat. Use it when the wound is full-thickness and not caused by pressure.
Clinical signs
Look for an open sore on the left lower leg with visible fat tissue in the wound bed. Clinical features vary; refer to documentation for depth, location, and whether the ulcer is chronic and non-pressure in origin.
When to use this code
Use this code when the record clearly states a chronic ulcer on the left lower leg, in another specified part of the lower leg, and documents fat layer exposure. It is appropriate for non-pressure ulcers from causes such as vascular or other chronic skin breakdown. Check documentation if the site or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers on the ankle or calf, or wounds without exposed fat. If the chart does not confirm laterality, location, or depth, check documentation.
Coding tip
Verify the exact anatomic site and tissue depth before assigning L97.822.
