ICD-10 Code L98.A116 – Non-pressure chronic ulcer of right upper arm with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A116 – Non-pressure chronic ulcer of right upper arm with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right upper arm that extends to the bone. You use it when the record shows bone involvement and no evidence of tissue death.
Clinical signs
Findings typically include a persistent open skin lesion on the right upper arm with exposed or involved bone. Clinical features vary; refer to documentation for depth, chronicity, and absence of necrosis.
When to use this code
Use this code when the provider documents a chronic ulcer of the right upper arm with bone involvement and explicitly states there is no necrosis. It fits non-pressure ulcers only, not pressure injuries. Confirm laterality and anatomic site in the note.
Do not use for
Do not use it for pressure ulcers, ulcers without bone involvement, or ulcers with necrosis. Check documentation if the site is not the right upper arm or if the ulcer type is unclear.
Coding tip
Verify both laterality and depth before coding, because the bone involvement and “without necrosis” details drive this specific code.
