What This Code Means

L03.111 is the ICD-10-CM diagnosis code for cellulitis of right axilla. A bacterial skin infection (cellulitis) affecting the right armpit area, causing redness, swelling, warmth, and tenderness. L03.111 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering infections of the skin and subcutaneous tissue (l00-l08).

L03.111 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
