ICD-10 Code L98.A311 – Non-pressure chronic ulcer of right hand limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A311 – Non-pressure chronic ulcer of right hand limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on the right hand that is limited to skin breakdown. Use it when documentation specifies the ulcer site and that the wound has not extended beyond the skin.
Clinical signs
Typical findings include a persistent open sore, superficial skin loss, or a nonhealing wound on the right hand. 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 right hand and the depth is limited to breakdown of skin. It is appropriate when the provider documents the site, chronicity, and superficial involvement. Check documentation if the laterality or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers of another body site. Do not assign it if documentation does not confirm right hand involvement or skin-level breakdown.
Coding tip
Verify the wound is chronic, non-pressure, and specifically documented as right hand with skin-only breakdown before assigning L98.A311.
