ICD-10 Code L03.113 – Cellulitis of right upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.113 – Cellulitis of right upper limb
What it is
L03.113 identifies cellulitis affecting the right upper limb. It means a bacterial skin and soft tissue infection involving the arm, forearm, wrist, or hand on the right side.
Clinical signs
Typical findings include localized redness, warmth, swelling, tenderness, and spreading skin inflammation. Clinical features vary; refer to documentation for the exact site and laterality.
When to use this code
Use this code when the provider documents cellulitis of the right upper limb and the affected side is clearly stated. It fits infection limited to the right arm region, including hand or forearm when documented that way. If the note only says cellulitis without laterality, check documentation.
Do not use for
Do not use L03.113 for cellulitis of the left arm, unspecified limb, or noninfectious redness and swelling. Do not use it when the record describes abscess, dermatitis, or another condition instead of cellulitis.
Coding tip
Verify both the diagnosis and right-sided location in the provider note before assigning this code.
