ICD-10 Code L98.463 – Non-pressure chronic ulcer of face with necrosis of muscle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.463 – Non-pressure chronic ulcer of face with necrosis of muscle
What it is
This code identifies a chronic ulcer on the face that is not caused by pressure and extends to necrosis of muscle. Use it when documentation clearly states facial tissue loss with muscle involvement.
Clinical signs
Typical documentation may note a persistent open facial wound, tissue breakdown, and exposed or necrotic muscle. Clinical features vary; refer to documentation.
When to use this code
Use L98.463 when the provider documents a non-pressure chronic ulcer specifically on the face and states necrosis of muscle. It may apply to long-standing wounds, nonhealing lesions, or ulcers with deeper tissue involvement. Check documentation for site and depth.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or facial ulcers without muscle necrosis. If the site or depth is unclear, check documentation.
Coding tip
Verify both the anatomic location and the documented depth before assigning L98.463.
