ICD-10 Code L02.2 – Cutaneous abscess, furuncle and carbuncle of trunk (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.2 – Cutaneous abscess, furuncle and carbuncle of trunk
What it is
This code identifies a localized bacterial skin infection on the trunk, such as an abscess, furuncle, or carbuncle. It applies when the affected area is the chest, back, abdomen, or similar trunk sites.
Clinical signs
Common findings include a painful, swollen, red, and warm lesion that may drain pus. A furuncle is usually a single infected hair follicle, while a carbuncle involves a cluster of interconnected boils; clinical features vary, refer to documentation.
When to use this code
Use L02.2 when the provider documents a cutaneous abscess, boil, or carbuncle located on the trunk. You should also use it when the record clearly identifies the trunk site, even if the note describes drainage, fluctuant swelling, or localized infection. Check documentation if the site is unclear or described only as “skin abscess.”
Do not use for
Do not use this code for abscesses on the face, limb, groin, or other non-trunk sites. Do not assign it when the documentation describes a deeper soft tissue infection or another diagnosis entirely.
Coding tip
Confirm both the lesion type and the anatomic site; L02.2 depends on trunk location being documented.
