ICD-10 Code L97.314 – Non-pressure chronic ulcer of right ankle with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.314 – Non-pressure chronic ulcer of right ankle with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on the right ankle that extends to and involves bone necrosis. Use it when the record clearly documents both the ulcer location and the depth.
Clinical signs
Typical findings include a persistent open wound at the right ankle with exposed or nonviable bone, often with surrounding tissue breakdown. Clinical features vary; refer to documentation.
When to use this code
Use L97.314 when the provider documents a chronic ulcer of the right ankle and specifies necrosis of bone. The note should support that the ulcer is non-pressure in origin and not simply a superficial wound. If laterality, site, or depth is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for pressure ulcers, acute traumatic wounds, or ulcers at another site. If bone involvement is not documented, choose the code that matches the recorded depth.
Coding tip
Confirm laterality, anatomic site, and ulcer depth in the provider note before coding.
