ICD-10 Code L98.A221 – Non-pressure chronic ulcer of left forearm limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A221 – Non-pressure chronic ulcer of left forearm limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on the left forearm that is limited to skin breakdown. Use it when the documentation specifies the left forearm and the ulcer has not extended into deeper tissue.
Clinical signs
Typical findings include an open skin lesion with superficial loss of the epidermis, localized drainage, or surrounding irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states a chronic non-pressure ulcer of the left forearm and the depth is limited to breakdown of skin. It is appropriate when the provider documents a superficial ulcer without exposed fat, muscle, or bone. Check documentation if laterality or depth is unclear.
Do not use for
Do not use it for pressure ulcers, traumatic wounds, or ulcers on another body site. Also avoid this code if the ulcer extends beyond skin breakdown or the documentation does not confirm the left forearm.
Coding tip
Match laterality and ulcer depth exactly to the provider note before assigning L98.A221.
