ICD-10 Code L03.11 – Cellulitis of other parts of limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.11 – Cellulitis of other parts of limb
What it is
This code identifies cellulitis affecting a limb area other than the hand or foot. It refers to a bacterial skin and soft tissue infection with diffuse inflammation of the deeper skin layers.
Clinical signs
Typical findings include localized redness, warmth, swelling, and tenderness of the affected limb. Clinical features vary; refer to documentation if the record does not clearly describe the site or extent.
When to use this code
Use L03.11 when the provider documents cellulitis in an arm, leg, or other limb site outside the hand or foot. Choose this code when the note supports a limb-specific infection and no more specific site code is documented.
If the record only says “cellulitis” without location, check documentation before assigning this code. You should also verify whether another code better matches the documented anatomic site.
Do not use for
Do not use this code for cellulitis of the hand or foot, which requires a different site-specific code. Do not use it when the documentation describes a different skin condition or the site is unclear.
Coding tip
Always match the code to the exact limb location documented by the provider.
