ICD-10 Code L98.A115 – Non-pressure chronic ulcer of right upper arm with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A115 – Non-pressure chronic ulcer of right upper arm with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right upper arm that extends into muscle, but there is no documented necrosis. Use it when the record clearly specifies the site and depth.
Clinical signs
Typical documentation includes a persistent open lesion of the right upper arm with exposed or involved muscle tissue. Clinical features vary; refer to documentation for ulcer depth, chronicity, and absence of necrotic tissue.
When to use this code
Use this code when the provider documents a chronic ulcer of the right upper arm with muscle involvement and states that necrosis is not present. It also fits when the note clearly supports a non-pressure ulcer at this site with that depth. Check documentation if laterality or tissue involvement is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers without muscle involvement, or ulcers with documented necrosis. If the site is not the right upper arm, or the record is vague, check documentation.
Coding tip
Verify laterality, depth, and the phrase “without evidence of necrosis” before assigning L98.A115.
