ICD-10 Code L03.011 – Cellulitis of right finger (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.011 – Cellulitis of right finger
What it is
L03.011 identifies cellulitis affecting the right finger. It means a bacterial skin and soft tissue infection with inflammation of the finger’s skin and subcutaneous tissue.
Clinical signs
Typical findings include localized redness, warmth, swelling, tenderness, and sometimes reduced finger motion. Clinical features vary; refer to documentation if the record is unclear.
When to use this code
Use this code when the provider documents cellulitis limited to the right finger. It is appropriate for infections described as finger cellulitis, infected finger skin, or similar right-sided localization. Ensure the note supports laterality and site.
Do not use for
Do not use it for cellulitis of another finger, the hand, or the entire upper limb. If the documentation only says “finger infection” without cellulitis, check documentation.
Coding tip
Verify the right-sided laterality in the chart before assigning L03.011.
