ICD-10 Code L98.A118 – Non-pressure chronic ulcer of right upper arm with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A118 – Non-pressure chronic ulcer of right upper arm with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the right upper arm with a documented severity that is not captured by a more specific ulcer category. Use it for a persistent skin breakdown that is not caused by pressure.
Clinical signs
Typical findings include an open wound with delayed healing, surrounding skin changes, and possible drainage or pain. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states a chronic ulcer on the right upper arm and the provider documents “other specified severity.” It fits cases where the ulcer is non-pressure in origin and laterality is right-sided. Check documentation if the cause, depth, or severity is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another site. If the chart does not specify the right upper arm or the documented severity, check documentation.
Coding tip
Match the ulcer site, laterality, and severity wording exactly as documented before assigning L98.A118.
