ICD-10 Code L02.413 – Cutaneous abscess of right upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.413 – Cutaneous abscess of right upper limb
What it is
This code identifies a localized skin abscess on the right upper limb, such as the arm, forearm, or hand. It means there is a pus-filled infection in the skin or just beneath it.
Clinical signs
Typical findings include a tender, swollen, red, and warm area that may drain pus or fluctuate on exam. Clinical features vary; refer to documentation.
When to use this code
Use L02.413 when the provider documents a cutaneous abscess specifically on the right upper limb. You may also use it when the note clearly localizes the abscess to the right arm region and does not describe a deeper infection. If the record only says “abscess” without site or laterality, check documentation.
Do not use for
Do not use this code for abscesses on the left upper limb, trunk, or lower extremities. It is also not appropriate for deeper soft tissue infections or unspecified abscesses when the right upper limb is not documented.
Coding tip
Verify both site and laterality in the provider note before assigning L02.413.
