ICD-10 Code L98.A114 – Non-pressure chronic ulcer of right upper arm with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A114 – Non-pressure chronic ulcer of right upper arm with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on the right upper arm with documented necrosis of bone. Use it when the wound is not caused by pressure and the bone is involved.
Clinical signs
Typical findings include a persistent open ulcer with exposed or necrotic bone in the right upper arm. Clinical features vary; refer to documentation for depth, chronicity, and any recorded tissue loss.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer of the right upper arm and specifically states necrosis of bone. The record should support both the site and the bone involvement. If laterality, chronicity, or bone necrosis is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without bone necrosis. Do not guess the site or severity if the note does not clearly document them.
Coding tip
Confirm the wound is non-pressure and that the right upper arm and bone necrosis are explicitly documented before coding.
