ICD-10 Code L02.532 – Carbuncle of left hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.532 – Carbuncle of left hand
What it is
L02.532 identifies a carbuncle located on the left hand. A carbuncle is a deeper skin infection made up of connected boils, usually involving several hair follicles and surrounding tissue.
Clinical signs
Typical findings include a painful, swollen, red, and tender area with pus drainage or multiple openings. Clinical features vary; refer to documentation if the chart does not clearly describe the lesion as a carbuncle.
When to use this code
Use this code when the provider documents a carbuncle specifically on the left hand. It may also fit when the note clearly localizes a deep staphylococcal-type skin abscess to that site. If the record says only “abscess” or “boil,” check documentation before assigning L02.532.
Do not use for
Do not use this code for cellulitis, simple abscess without carbuncle documentation, or infections on another hand site. If laterality is missing or the lesion is elsewhere, choose the documented diagnosis instead.
Coding tip
Verify both the lesion type and the left-hand location in the provider note before coding.
