ICD-10 Code L02 – Cutaneous abscess, furuncle and carbuncle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02 – Cutaneous abscess, furuncle and carbuncle
What it is
L02 identifies localized skin and subcutaneous infections that form pus, including abscesses, furuncles, and carbuncles. Use it when the record describes a cutaneous collection of infection rather than a deeper or systemic process.
Clinical signs
Typical findings include a painful, swollen, red, and tender skin lesion, sometimes with warmth or visible drainage. Clinical features vary; refer to documentation.
When to use this code
Use L02 when the provider documents a cutaneous abscess, furuncle, or carbuncle without a more specific site code. It also fits when the note clearly describes a skin-level purulent infection. If the location is specified, select the most specific ICD-10-CM code available.
Do not use for
Do not use L02 for acne, cellulitis without abscess, or deeper soft tissue infections unless the record supports a cutaneous abscess. Check documentation if the site or depth is unclear.
Coding tip
Confirm the anatomic site and whether the lesion is an abscess, furuncle, or carbuncle before assigning the final code.
