ICD-10 Code L97.816 – Non-pressure chronic ulcer of other part of right lower leg with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.816 – Non-pressure chronic ulcer of other part of right lower leg with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of the right lower leg that extends to bone. The documentation also states there is no necrosis.
Clinical signs
Expect a persistent open wound with exposed or involved bone, usually on the right lower leg outside the heel or ankle. Clinical features vary; refer to documentation.
When to use this code
Use L97.816 when the provider documents a chronic non-pressure ulcer of the right lower leg and specifically notes bone involvement without necrosis. Apply it only when the ulcer site is not better described by a more specific lower-leg location. Check documentation if laterality, depth, or necrosis status is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without bone involvement. Also avoid it if the record documents necrosis, a different leg, or a more specific site code.
Coding tip
Verify both laterality and depth in the wound note before assigning the code.
