ICD-10 Code L98.A111 – Non-pressure chronic ulcer of right upper arm limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A111 – Non-pressure chronic ulcer of right upper arm limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on the right upper arm that is limited to breakdown of the skin. It is used when the lesion is not caused by pressure and does not extend beyond superficial skin loss.
Clinical signs
Expect a persistent open skin lesion on the right upper arm with superficial tissue loss. Clinical features vary; refer to documentation, but the record should support a chronic ulcer and confirm that deeper structures are not involved.
When to use this code
Use this code when documentation specifies a chronic non-pressure ulcer of the right upper arm and states the depth is limited to breakdown of skin. It fits outpatient or inpatient notes that clearly localize the ulcer to the right upper arm. If the cause, site, or depth is unclear, check documentation before assigning the code.
Do not use for
Do not use it for pressure ulcers, traumatic wounds, or ulcers at another anatomic site. Also avoid it if documentation shows deeper tissue involvement or does not confirm the right upper arm.
Coding tip
Verify both laterality and ulcer depth in the provider note before coding.
