ICD-10 Code L02.8 – Cutaneous abscess, furuncle and carbuncle of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.8 – Cutaneous abscess, furuncle and carbuncle of other sites
What it is
This code identifies a localized skin infection with pus, including an abscess, boil, or carbuncle, when it occurs at a site not named in a more specific ICD-10 category. Use it when the record clearly shows a cutaneous lesion but the site is documented as “other.”
Clinical signs
Typical findings include a painful, swollen, red, and tender skin lump that may drain pus. Clinical features vary; refer to documentation for the exact site and whether the lesion is an abscess, furuncle, or carbuncle.
When to use this code
Use L02.8 when the provider documents a cutaneous abscess, furuncle, or carbuncle at a specified site that is not separately listed in the code set. It is appropriate when the condition is clearly skin-based and the documentation supports an “other site” location. Check documentation if the anatomic site is unclear.
Do not use for
Do not use this code for abscesses in organs, deep tissues, or other noncutaneous locations. If the note names a more specific site code or the diagnosis is uncertain, check documentation before assigning L02.8.
Coding tip
Match the coded site to the provider’s exact wording and choose a more specific code whenever one exists.
