ICD-10 Code L02.224 – Furuncle of groin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.224 – Furuncle of groin
What it is
L02.224 identifies a furuncle, or boil, located in the groin area. It refers to a localized bacterial infection of a hair follicle that forms a painful, pus-filled nodule.
Clinical signs
Typical findings include a tender, red, swollen lump in the groin that may enlarge and drain pus. Clinical features vary; refer to documentation.
When to use this code
Use this code when documentation specifically states a furuncle in the groin region. It is appropriate for a single boil or localized abscess-like lesion centered on a hair follicle. If the record only says “skin infection” or “abscess” without location, check documentation.
Do not use for
Do not use it for cellulitis, hidradenitis suppurativa, or an unspecified skin abscess. Check documentation if the lesion is described as a carbuncle or if the groin location is not clearly stated.
Coding tip
Confirm both the diagnosis and the anatomic site; L02.224 requires groin-specific documentation.
