L02.4 — Cutaneous abscess, furuncle and carbuncle of limb
L02.4 is a non-billable header ICD-10-CM code for cutaneous abscess, furuncle and carbuncle of limb. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Excludes2 inherited from the categories above L02.4
Also inherited, and the opposite of Excludes1: these conditions are not part of L02.4, but a patient can have both, so you may code both.
Risk adjustment
L02.4 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
L02.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
