ICD-10 Code L02.519 – Cutaneous abscess of unspecified hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.519 – Cutaneous abscess of unspecified hand
What it is
This code identifies a localized skin abscess on the hand when the site is not further specified. It refers to a pus-filled infection in the skin and subcutaneous tissue of the hand.
Clinical signs
Typical findings include a tender, swollen, red, and warm area on the hand, sometimes with fluctuance or drainage. Clinical features vary; refer to documentation.
When to use this code
Use L02.519 when the record documents a cutaneous abscess of the hand but does not state whether it is right or left, or provide a more specific hand location. It is appropriate for outpatient, emergency, or inpatient documentation when the diagnosis is clearly a skin abscess. If the note identifies a more specific site, code that instead.
Do not use for
Do not use this code for abscesses of the finger, thumb, or nail unit when a more specific code is documented. Do not use it for deeper hand infections, osteomyelitis, or cellulitis without an abscess; check documentation.
Coding tip
Confirm laterality and exact anatomic site before assigning the unspecified code.
