ICD-10 Code L98.466 – Non-pressure chronic ulcer of face with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.466 – Non-pressure chronic ulcer of face with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the face that extends to the bone but shows no necrosis. Use it when documentation states the facial ulcer is longstanding and bone is involved.
Clinical signs
Findings may include an open facial wound with exposed or affected bone, persistent drainage, and delayed healing. Clinical features vary; refer to documentation for confirmation of bone involvement and absence of necrotic tissue.
When to use this code
Use L98.466 when the record clearly documents a chronic ulcer on the face with bone involvement and specifically notes no necrosis. It fits outpatient, inpatient, or wound-care documentation when the provider describes depth and location. Check documentation if the ulcer site or tissue status is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without bone involvement. It also should not be used if necrosis is present or if the facial location is not documented.
Coding tip
Confirm both the anatomic site and the phrase “without evidence of necrosis” before assigning L98.466.
