ICD-10 Code L03.2 – Cellulitis and acute lymphangitis of face and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.2 – Cellulitis and acute lymphangitis of face and neck
What it is
L03.2 identifies an acute bacterial infection of the skin and subcutaneous tissue on the face or neck, including lymphatic involvement. Use it when the documentation specifies cellulitis or acute lymphangitis in these locations.
Clinical signs
Typical findings include localized redness, warmth, swelling, tenderness, and spreading inflammation of the face or neck. Clinical features vary; refer to documentation for the exact site and whether lymphangitis is noted.
When to use this code
Use L03.2 when the provider documents cellulitis, acute lymphangitis, or both affecting the face or neck. It also fits cases described as facial or neck soft tissue infection when the record clearly supports these anatomic sites.
Do not use for
Do not use this code for abscess, erysipelas, or infections outside the face and neck. Check documentation if the record only says skin infection without a precise diagnosis or location.
Coding tip
Confirm both the diagnosis and anatomic site in the note, because laterality is not the key issue here.
