ICD-10 Code L02.212 – Cutaneous abscess of back [any part, except buttock and flank] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.212 – Cutaneous abscess of back [any part, except buttock and flank]
What it is
L02.212 identifies a localized skin abscess on the back, excluding the buttock and flank. It means a collection of pus in the skin or subcutaneous tissue of the back.
Clinical signs
Typical findings include a tender, swollen, red, and warm lump on the back, sometimes with fluctuance or drainage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents a cutaneous abscess on any part of the back, and the site is not the buttock or flank. It also fits when the provider describes a skin abscess, boil, or localized purulent infection of the back. Check documentation if the location is unclear.
Do not use for
Do not use this code for abscesses on the buttock or flank, or for deeper infections that are not cutaneous. If the chart does not specify the back as the site, choose a more accurate code.
Coding tip
Confirm the exact anatomic site in the note before assigning L02.212.
