ICD-10 Code L02.512 – Cutaneous abscess of left hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.512 – Cutaneous abscess of left hand
What it is
L02.512 identifies a localized skin abscess on the left hand. It means a pocket of pus in the skin or superficial tissue, usually from a bacterial infection.
Clinical signs
Typical findings include a tender, swollen, red, and warm area on the left hand, sometimes with drainage or fluctuance. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a cutaneous abscess specifically on the left hand. It fits a superficial abscess of the hand skin or subcutaneous tissue, not a deeper hand infection. If the note only says “hand abscess” without laterality, check documentation.
Do not use for
Do not use L02.512 for abscesses in the fingers, nail fold, or deeper structures of the hand. Also avoid it when the record describes cellulitis, an infected wound, or another site.
Coding tip
Confirm both the anatomic site and laterality in the provider note before assigning L02.512.
