ICD-10 Code L02.32 – Furuncle of buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.32 – Furuncle of buttock
What it is
L02.32 identifies a boil, or localized skin abscess, on the buttock caused by infection of a hair follicle. Use this code when the record specifically documents a furuncle in that anatomic site.
Clinical signs
Typical findings include a tender, red, swollen nodule that may develop a central pustule or drain pus. Clinical features vary; refer to documentation.
When to use this code
Use L02.32 when the clinician documents a furuncle or boil of the buttock, including a localized abscess limited to that area. Code it from the diagnosis in the note, operative report, or discharge summary. If the site is described differently or the lesion is more extensive, check documentation.
Do not use for
Do not use this code for cellulitis, pilonidal disease, or abscesses at other body sites. If the documentation does not clearly identify a buttock furuncle, check documentation.
Coding tip
Confirm that the provider names the buttock as the source site before assigning L02.32.
