ICD-10 Code L02.62 – Furuncle of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.62 – Furuncle of foot
What it is
L02.62 identifies a furuncle, or boil, located on the foot. It refers to a localized bacterial infection of a hair follicle with surrounding skin involvement.
Clinical signs
Typical findings include a tender, red, swollen nodule on the foot that may develop a central pus point or drainage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents a furuncle on the foot, such as a boil or abscessed follicular infection in that location. Code it from provider documentation, not from a nonspecific skin infection note. If the site is elsewhere or not specified, check documentation.
Do not use for
Do not use this code for cellulitis, carbuncle, or a generalized skin abscess without foot involvement. If the documentation does not confirm a furuncle, check documentation.
Coding tip
Confirm both the lesion type and the anatomic site in the note before assigning L02.62.
