ICD-10 Code L98.A128 – Non-pressure chronic ulcer of left upper arm with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A128 – Non-pressure chronic ulcer of left upper arm with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left upper arm with a severity not otherwise specified. Use it when documentation confirms the ulcer site and indicates an “other specified” level of severity.
Clinical signs
Typical findings include a persistent open skin lesion on the left upper arm with tissue loss and delayed healing. Clinical features vary; refer to documentation for depth, drainage, and any surrounding skin changes.
When to use this code
Use this code when the record clearly states a chronic non-pressure ulcer of the left upper arm and the provider documents other specified severity. It applies when the ulcer is not described as pressure-related and no more specific severity code is documented. Check documentation if laterality or severity is unclear.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or acute skin breaks. If the chart does not specify left upper arm or the severity category, check documentation before coding.
Coding tip
Match the code to both laterality and the exact severity wording in the note.
