ICD-10 Code L03.115 – Cellulitis of right lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.115 – Cellulitis of right lower limb
What it is
This code identifies cellulitis affecting the right lower limb. It refers to a bacterial skin and soft tissue infection involving the right leg, ankle, or foot when documentation specifies the right side.
Clinical signs
Typical findings include localized redness, warmth, swelling, and tenderness of the affected right lower limb. Clinical features vary; refer to documentation for the exact site and whether the infection is superficial or deeper.
When to use this code
Use L03.115 when the provider documents cellulitis of the right lower limb without a more specific anatomic or infectious diagnosis. It is appropriate for notes describing right leg cellulitis, right lower extremity cellulitis, or similar wording. If the record only says “cellulitis” and laterality is not stated, check documentation.
Do not use for
Do not use this code for cellulitis of the left lower limb, unspecified limb, or non-lower-extremity cellulitis. Do not use it when the diagnosis is a different skin condition or when documentation does not support cellulitis.
Coding tip
Confirm laterality in the assessment or final diagnosis before assigning L03.115.
