ICD-10 Code L02.233 – Carbuncle of chest wall (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.233 – Carbuncle of chest wall
What it is
This code identifies a carbuncle located on the chest wall. A carbuncle is a deeper skin infection made up of connected boils, usually involving several hair follicles.
Clinical signs
Typical findings include a painful, swollen, red area with pus drainage or multiple openings. Clinical features vary; refer to documentation if the record does not clearly describe a carbuncle on the chest wall.
When to use this code
Use L02.233 when the provider documents a carbuncle specifically on the chest wall. It is appropriate when the location is clear and the lesion is described as a carbuncle rather than a simple abscess or furuncle. If the site is unclear, check documentation.
Do not use for
Do not use this code for abscesses, furuncles, or other skin infections unless the record specifically states carbuncle. Do not assume chest wall involvement without explicit documentation.
Coding tip
Always confirm both the lesion type and the exact anatomic site before assigning L02.233.
