ICD-10 Code L98.A – Non-pressure chronic ulcer of upper limb, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A – Non-pressure chronic ulcer of upper limb, not elsewhere classified
What it is
This code identifies a chronic ulcer on the upper limb that is not caused by pressure and does not fit a more specific ulcer category. Use it when documentation clearly describes a persistent skin breakdown of the arm, forearm, wrist, or hand.
Clinical signs
Typical findings include an open skin lesion with delayed healing, drainage, or surrounding inflammation. Clinical features vary; refer to documentation for location, chronicity, and whether the ulcer is non-pressure related.
When to use this code
Use L98.A when the record states a chronic non-pressure ulcer of the upper limb and no more specific diagnosis is provided. It may appear in follow-up notes, wound care documentation, or specialist assessments. Check documentation if the cause or site is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers with a more specific documented cause. If the ulcer is in another body site, or the chart does not support chronicity, check documentation.
Coding tip
Confirm the ulcer is chronic, non-pressure, and located on the upper limb before assigning L98.A.
