ICD-10 Code L02.818 – Cutaneous abscess of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.818 – Cutaneous abscess of other sites
What it is
L02.818 identifies a localized skin abscess at a site not named by a more specific ICD-10 code. It refers to a pus-filled infection in the skin or subcutaneous tissue.
Clinical signs
Typical findings include a tender, swollen, red, and warm skin lesion, sometimes with fluctuance or drainage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a cutaneous abscess on an unspecified other body site and no more specific site code applies. It is appropriate for skin abscesses outside the coded locations in the index or tabular list. Check documentation if the note only says “abscess” without confirming a cutaneous source.
Do not use for
Do not use it for abscesses with a more specific anatomic code, such as face, limb, or trunk, when documented. Do not assign it for deep organ, postoperative, or noncutaneous abscesses.
Coding tip
Verify the exact body site in the assessment and choose a more specific code whenever the record supports one.
