ICD-10 Code L98.A11 – Non-pressure chronic ulcer of right upper arm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A11 – Non-pressure chronic ulcer of right upper arm
What it is
This code identifies a chronic, non-pressure ulcer located on the right upper arm. Use it when the record documents a persistent skin breakdown in that site, not caused by pressure.
Clinical signs
Look for an open sore or ulcer with delayed healing on the right upper arm. Clinical features vary; refer to documentation for depth, drainage, pain, or surrounding skin changes.
When to use this code
Use this code when the provider clearly documents a chronic ulcer of the right upper arm and the lesion is not a pressure injury. It fits outpatient or inpatient records that specify the site and chronic nature. Check documentation if laterality or ulcer type is unclear.
Do not use for
Do not use it for pressure ulcers, acute wounds, or ulcers at another arm site. If the note does not confirm a chronic non-pressure ulcer, check documentation.
Coding tip
Confirm both laterality and the non-pressure, chronic nature of the ulcer before assigning L98.A11.
