ICD-10 Code H05.011 – Cellulitis of right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.011 – Cellulitis of right orbit
What it is
H05.011 identifies cellulitis involving the right orbit, meaning an acute bacterial infection of the tissues behind or around the eye. Use it when documentation specifically states the right orbital side.
Clinical signs
Typical findings include painful eye movement, eyelid swelling, redness, and orbital tenderness. Clinical features vary; refer to documentation for laterality and whether the infection is orbital rather than superficial eyelid cellulitis.
When to use this code
Use H05.011 when the provider documents cellulitis of the right orbit, orbital cellulitis, or infection of right orbital soft tissues. Code it from specialist notes, imaging reports, or discharge summaries that clearly support the diagnosis. Verify laterality before assigning the code.
Do not use for
Do not use this code for preseptal or eyelid cellulitis, unspecified orbital cellulitis, or left-sided disease. Check documentation if the note only says “eye infection” or “orbital inflammation.”
Coding tip
Always confirm the word “right” in the record, because laterality is built into this code.
