ICD-10 Code H05.013 – Cellulitis of bilateral orbits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.013 – Cellulitis of bilateral orbits
What it is
H05.013 identifies cellulitis involving both orbits, meaning an infection and inflammation of the tissues around both eyes. Use it when the documentation clearly states bilateral orbital cellulitis.
Clinical signs
Typical findings include eyelid swelling, redness, pain, and tenderness around both eyes. Clinical features may also include restricted eye movement or proptosis; refer to documentation.
When to use this code
Use this code when the provider documents cellulitis affecting both orbits or both sides of the eye sockets. It may appear in acute infectious eye conditions with orbital involvement. If laterality is not stated, check the record before assigning a bilateral code.
Do not use for
Do not use H05.013 for simple eyelid cellulitis, preseptal cellulitis, or unspecified orbital cellulitis. If the note does not clearly support bilateral orbital involvement, check documentation.
Coding tip
Verify both laterality and orbital location in the provider note before coding.
