ICD-10 Code L98.A3 – Non-pressure chronic ulcer of hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A3 – Non-pressure chronic ulcer of hand
What it is
This code identifies a chronic, non-pressure ulcer located on the hand. Use it when documentation shows a persistent open skin lesion not caused by pressure injury.
Clinical signs
Typical findings include an open sore on the hand with delayed healing, drainage, or exposed tissue. Clinical features vary; refer to documentation.
When to use this code
Use L98.A3 when the provider documents a chronic ulcer of the hand and does not describe it as a pressure ulcer, burn, or traumatic wound. It may apply to long-standing skin breakdown requiring ongoing assessment. Check documentation for laterality, depth, and any associated infection or necrosis.
Do not use for
Do not use this code for pressure ulcers, acute lacerations, burns, or traumatic wounds of the hand. If the record does not clearly state a chronic non-pressure ulcer, check documentation.
Coding tip
Confirm the ulcer is chronic and non-pressure, and code the hand location exactly as documented.
