ICD-10 Code L02.419 – Cutaneous abscess of limb, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L02.419 – Cutaneous abscess of limb, unspecified
What it is
This code identifies a localized skin abscess on an arm or leg when the chart does not specify the exact limb or side. It reflects a collection of pus in the skin or subcutaneous tissue.
Clinical signs
Typical findings include a tender, swollen, red, and warm area with possible fluctuation or drainage. Clinical features vary; refer to documentation.
When to use this code
Use L02.419 when the provider documents a cutaneous abscess of a limb but does not state whether it is upper or lower extremity, or does not identify the side. It also fits when the record confirms a skin abscess on a limb and no more specific code is supported. Check documentation if the note describes cellulitis, deeper infection, or a different site.
Do not use for
Do not use this code for abscesses of the trunk, head, face, or other non-limb sites. Do not assign it when the provider specifies a more exact limb or laterality code.
Coding tip
If the note names the limb or side, code the more specific option instead of this unspecified code.
