ICD-10 Code L02.6 – Cutaneous abscess, furuncle and carbuncle of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.6 – Cutaneous abscess, furuncle and carbuncle of foot
What it is
L02.6 identifies a localized bacterial skin infection on the foot that forms an abscess, furuncle, or carbuncle. Use it when the documentation specifies the foot as the affected site.
Clinical signs
Typical findings include a painful, swollen, red, and warm lesion on the foot, often with pus or drainage. Clinical features vary; refer to documentation.
When to use this code
Use L02.6 when the provider documents a cutaneous abscess, furuncle, or carbuncle involving the foot. It also fits when the note clearly localizes the infection to the foot, even if the exact lesion type is not further detailed. Check documentation if the site is described more broadly.
Do not use for
Do not use this code for abscesses in other body sites, such as the toe or lower leg, unless the foot is specifically documented. Do not use it when the record only states cellulitis, because that is coded separately.
Coding tip
Confirm both the lesion type and the anatomic site in the provider note before assigning L02.6.
