ICD-10 Code L02.0 – Cutaneous abscess, furuncle and carbuncle of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.0 – Cutaneous abscess, furuncle and carbuncle of face
What it is
L02.0 identifies a localized bacterial infection of the skin on the face, including a cutaneous abscess, furuncle, or carbuncle. Use it when the documentation specifies the facial site and one of these lesion types.
Clinical signs
Typical findings include a painful, swollen, red, and tender facial lesion with possible pus or drainage. A carbuncle may show multiple connected boils; if the record is unclear, check documentation.
When to use this code
Use this code when the clinician documents a facial abscess, boil, or carbuncle and the site is the face. It also fits when the note describes a localized purulent skin infection on the face without a more specific alternative code. If laterality or exact subtype is not stated, code only what is documented.
Do not use for
Do not use L02.0 for acne, cellulitis without abscess, or infections on body sites other than the face. If the documentation names a different anatomical location, select the site-specific code instead.
Coding tip
Verify both the lesion type and facial location in the record before assigning L02.0.
