ICD-10 Code L02.5 – Cutaneous abscess, furuncle and carbuncle of hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.5 – Cutaneous abscess, furuncle and carbuncle of hand
What it is
L02.5 identifies a localized bacterial skin infection of the hand, including a cutaneous abscess, furuncle, or carbuncle. Use it when the infection is specifically documented as involving the hand.
Clinical signs
Typical findings include a painful, swollen, red, and warm lesion with pus or drainage. Clinical features vary; refer to documentation for whether it is an abscess, furuncle, or carbuncle.
When to use this code
Use L02.5 when the provider documents a cutaneous abscess, boil, or carbuncle on the hand. It is appropriate when the site is clearly the hand and the condition is not described as deeper tissue infection or another diagnosis.
If the record only says “skin infection” or the location is unclear, check documentation before coding. You should also confirm whether the lesion is on the hand rather than the wrist, finger, or another site.
Do not use for
Do not use this code for abscesses on other body sites or for infections limited to deeper structures of the hand. Check documentation if the diagnosis is cellulitis, tenosynovitis, or an unspecified soft tissue infection.
Coding tip
Match the code to the exact anatomic site and documented lesion type; when the hand is not clearly stated, query the provider.
