ICD-10 Code L03.114 – Cellulitis of left upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.114 – Cellulitis of left upper limb
What it is
L03.114 identifies cellulitis affecting the left upper limb. It describes an acute bacterial skin and subcutaneous tissue infection of the left arm, forearm, wrist, or hand, depending on documentation.
Clinical signs
Common findings include localized redness, warmth, swelling, tenderness, and skin pain in the left upper limb. Clinical features vary; refer to documentation for the exact site and whether the infection is diffuse or spreading.
When to use this code
Use this code when the provider documents cellulitis of the left upper limb without a more specific site code. It is appropriate for infection involving the left arm or adjacent upper-extremity tissues when laterality is clearly stated. If the record specifies a different anatomic location or a different diagnosis, choose the documented condition instead.
Do not use for
Do not use this code for abscess, open wound infection, dermatitis, or other non-cellulitic skin conditions. Check documentation if the note does not clearly identify cellulitis of the left upper limb.
Coding tip
Verify laterality and the exact upper-extremity site in the note before assigning L03.114.
