ICD-10 Code L98.462 – Non-pressure chronic ulcer of face with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.462 – Non-pressure chronic ulcer of face with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the face that extends through the skin into the fat layer. It is used when documentation confirms exposed subcutaneous tissue and the ulcer is not caused by pressure.
Clinical signs
Typical findings include an open facial wound with visible fat, delayed healing, and surrounding skin breakdown. Clinical features vary; refer to documentation for depth, location, and chronicity.
When to use this code
Use L98.462 when the record clearly states a chronic ulcer of the face with fat layer exposed and no pressure etiology. You should code it when the provider documents the ulcer depth and facial location. If the site or depth is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or facial lesions without ulceration. It is also inappropriate if the record does not confirm exposed fat layer.
Coding tip
Verify both the anatomic site and ulcer depth in the provider note before assigning L98.462.
