ICD-10 Code L02.414 – Cutaneous abscess of left upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.414 – Cutaneous abscess of left upper limb
What it is
L02.414 identifies a localized skin abscess on the left upper limb. It means there is a pus-filled infection in the skin or subcutaneous tissue of the arm, forearm, wrist, or hand on the left side.
Clinical signs
Typical findings include a tender, swollen, red, warm lesion that may drain pus. Clinical features vary; refer to documentation for the exact site and whether the abscess is superficial or deeper.
When to use this code
Use this code when the record clearly documents a cutaneous abscess limited to the left upper limb. It fits cases described as abscess, furuncle-like skin infection, or localized purulent collection on the left arm or related upper-extremity skin. Confirm laterality and anatomic location in the note.
Do not use for
Do not use it for abscesses on the right upper limb, trunk, or lower extremity. Do not assign it when the documentation only states cellulitis, deep infection, or an unspecified skin abscess without left upper-limb location.
Coding tip
Code the documented side and site exactly; if the location is unclear, check documentation before assigning L02.414.
