ICD-10 Code L03.119 – Cellulitis of unspecified part of limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.119 – Cellulitis of unspecified part of limb
What it is
L03.119 identifies cellulitis affecting a limb when the record does not specify the exact arm or leg location. It is used for a bacterial skin and soft tissue infection with diffuse inflammation.
Clinical signs
Typical findings include localized redness, warmth, swelling, and tenderness of the affected limb. Clinical features vary; refer to documentation for any associated drainage, fever, or spreading erythema.
When to use this code
Use this code when the provider documents cellulitis of an unspecified limb and does not name a more precise site. It is appropriate when the chart confirms limb involvement but not whether the infection is in the upper or lower extremity. If documentation later specifies the exact limb, code to that level instead.
Do not use for
Do not use it for cellulitis of a clearly identified arm, leg, hand, or foot when a more specific code is documented. Check documentation if the condition is abscess, dermatitis, or another skin disorder rather than cellulitis.
Coding tip
Query for laterality and exact limb site whenever the note says only “cellulitis” or “limb infection.”
