ICD-10 Code L98.A224 – Non-pressure chronic ulcer of left forearm with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A224 – Non-pressure chronic ulcer of left forearm with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on the left forearm with bone necrosis. Use it when documentation shows a persistent skin breakdown in that location and the bone beneath is dead or devitalized.
Clinical signs
Typical findings include an open ulcer on the left forearm that does not heal normally and evidence of exposed, infected, or necrotic bone. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents a chronic non-pressure ulcer of the left forearm and states necrosis of bone. It may appear in wound care, surgical, or specialty notes when the ulcer depth reaches bone involvement. Check documentation if the laterality or bone status is unclear.
Do not use for
Do not use it for pressure ulcers, acute wounds, or ulcers on another site. Do not assume bone necrosis unless the provider documents it clearly.
Coding tip
Verify both laterality and the “necrosis of bone” detail in the note before assigning L98.A224.
