ICD-10 Code L02.61 – Cutaneous abscess of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.61 – Cutaneous abscess of foot
What it is
L02.61 identifies a localized collection of pus in the skin or subcutaneous tissue of the foot. Use it when documentation shows a cutaneous abscess rather than a deeper infection.
Clinical signs
Typical findings include a painful, swollen, red, and warm area on the foot, sometimes with fluctuance or drainage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a cutaneous abscess on the foot, including a localized skin abscess or boil in that site. It may also fit when the note clearly describes an abscess limited to the skin and subcutaneous tissue. Check documentation if the infection involves deeper structures.
Do not use for
Do not use L02.61 for cellulitis, deep soft tissue infection, or osteomyelitis of the foot. If the record only says “foot infection” without abscess detail, check documentation.
Coding tip
Code the abscess site exactly as documented, and verify whether the infection is cutaneous or deeper before assigning L02.61.
