ICD-10 Code L02.217 – Cutaneous abscess of flank (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.217 – Cutaneous abscess of flank
What it is
L02.217 identifies a localized skin abscess on the flank, meaning a pocket of pus in the soft tissue on the side of the trunk. Use it when the documentation specifically states a cutaneous abscess in that area.
Clinical signs
Typical findings include a tender, swollen, red, and warm lesion that may drain pus. Clinical features vary; refer to documentation for whether the abscess is superficial and located on the flank.
When to use this code
Use this code when the provider documents a cutaneous abscess of the flank, including a localized skin infection with pus collection at that site. It may also fit if the note clearly identifies a flank skin abscess without deeper tissue involvement. Check documentation if the site is described ambiguously or if the process is deeper than skin.
Do not use for
Do not use this code for cellulitis without abscess, deep soft tissue infection, or abscesses at another body site. If the record does not clearly support a cutaneous flank abscess, check documentation.
Coding tip
Confirm the anatomic site and that the abscess is cutaneous before assigning L02.217.
