ICD-10 Code L98.A292 – Non-pressure chronic ulcer of unspecified forearm with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A292 – Non-pressure chronic ulcer of unspecified forearm with fat layer exposed
What it is
This code identifies a chronic non-pressure ulcer on the forearm, with the fatty tissue beneath the skin exposed. Use it when the record shows the ulcer site is the forearm but does not specify left or right.
Clinical signs
Typical findings include a persistent open wound, visible subcutaneous fat, and delayed healing. Clinical features vary; refer to documentation for laterality, depth, and whether infection or other complications are present.
When to use this code
Use this code when the provider documents a chronic ulcer of the forearm and specifies fat layer exposure, but does not identify the side. It is appropriate for non-pressure ulcers only, such as chronic skin breakdown not caused by pressure.
If the note describes a different anatomic site, a pressure injury, or a more specific forearm location and laterality, choose the documented code instead. Check documentation when the depth or chronicity is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without exposed fat layer. It is also wrong when the record identifies a more specific forearm code or laterality.
Coding tip
Confirm that the ulcer is chronic, non-pressure, and located on the unspecified forearm before assigning L98.A292.
