ICD-10 Code L02.02 – Furuncle of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.02 – Furuncle of face
What it is
L02.02 identifies a boil, or localized skin abscess, on the face. It means a painful, pus-filled infection centered on a hair follicle or nearby skin.
Clinical signs
Typical findings include a tender, red, swollen nodule on the face that may drain pus or form a central point. Clinical features vary; refer to documentation.
When to use this code
Use L02.02 when the record clearly documents a furuncle on the face, such as the cheek, lip, nose, or forehead. Code it when the provider identifies the lesion as a boil or furuncle rather than a broader skin infection. If the site or diagnosis is unclear, check documentation.
Do not use for
Do not use this code for acne, cellulitis without abscess, or abscesses at other body sites. If the note describes a different facial skin disorder, choose the more specific diagnosis.
Coding tip
Confirm both the facial location and the term “furuncle” or “boil” in the assessment before assigning L02.02.
