ICD-10 Code L98.464 – Non-pressure chronic ulcer of face with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.464 – Non-pressure chronic ulcer of face with necrosis of bone
What it is
This code identifies a chronic non-pressure ulcer on the face that extends to and involves necrosis of bone. Use it when the documentation specifically confirms both the facial location and bone necrosis.
Clinical signs
Findings may include a persistent open facial ulcer with exposed or nonviable bone, tissue breakdown, and delayed healing. Clinical features vary; refer to documentation for depth, location, and any noted necrosis.
When to use this code
Use L98.464 when the provider documents a chronic ulcer of the face and states that necrosis of bone is present. This applies to non-pressure ulcers, not acute wounds or pressure-related injuries. If the record is unclear about depth or cause, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute traumatic wounds, or facial ulcers without bone necrosis. If the ulcer site is different or necrosis is not documented, choose another code.
Coding tip
Confirm that both “face” and “necrosis of bone” are documented before assigning L98.464.
