2026 ICD-10-CM Diagnosis Code L98.A31 – Non-pressure chronic ulcer of right hand
What it is
This code identifies a chronic ulcer on the right hand that is not caused by pressure. Use it when the record clearly documents a persistent skin breakdown or open sore on the right hand.
Clinical signs
Typical findings include a nonhealing open lesion, loss of skin integrity, and local tissue damage on the right hand. Clinical features vary; refer to documentation.
When to use this code
Use L98.A31 when the clinician documents a chronic non-pressure ulcer specifically located on the right hand. It is appropriate for outpatient, inpatient, or wound-care records when the site and chronic nature are stated. Confirm laterality and that the lesion is not described as pressure-related.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at another hand site. Check documentation if the note describes infection, trauma, or a different anatomic location.
Coding tip
Verify the right-hand laterality and chronic ulcer wording before assigning the code.
