ICD-10 Code L98.A213 – Non-pressure chronic ulcer of right forearm with necrosis of muscle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A213 – Non-pressure chronic ulcer of right forearm with necrosis of muscle
What it is
This code identifies a chronic, non-pressure ulcer on the right forearm with necrosis of muscle. Use it when documentation shows a persistent skin breakdown that extends to muscle tissue.
Clinical signs
Typical findings include an open ulcer on the right forearm with tissue loss and exposed or necrotic muscle. Clinical features vary; refer to documentation for depth, chronicity, and any wound description.
When to use this code
Use this code when the record clearly states a non-pressure chronic ulcer of the right forearm and specifies necrosis of muscle. Apply it when the anatomic site and tissue depth are documented together.
If the note only says “ulcer” without laterality, chronicity, or depth, check documentation before assigning this code. You may need a different code if the lesion is pressure-related or located elsewhere.
Do not use for
Do not use it for pressure ulcers, acute wounds, or ulcers without documented muscle necrosis. Check documentation if the site is not the right forearm or if depth is unspecified.
Coding tip
Confirm both laterality and the deepest documented tissue involvement before coding.
