ICD-10 Code L98.A2 – Non-pressure chronic ulcer of forearm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A2 – Non-pressure chronic ulcer of forearm
What it is
L98.A2 identifies a chronic skin ulcer on the forearm that is not caused by pressure. Use it when the record documents a persistent open lesion with tissue loss in that location.
Clinical signs
Typical findings include an open, nonhealing wound on the forearm with drainage, granulation tissue, or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer specifically on the forearm. It fits ongoing ulcers that are not described as pressure injuries, traumatic wounds, or acute abrasions. If the note only says “wound” or “lesion,” check documentation for ulcer terminology.
Do not use for
Do not use it for pressure ulcers, acute traumatic wounds, or simple skin breaks without ulceration. If the site is not the forearm, or the documentation is unclear, check documentation.
Coding tip
Verify both the chronic ulcer wording and the forearm location before assigning L98.A2.
