ICD-10 Code H05.02 – Osteomyelitis of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.02 – Osteomyelitis of orbit
What it is
H05.02 identifies osteomyelitis affecting the bony orbit. Use it when the record documents infection and inflammation of the orbital bone, not just surrounding soft tissue.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include orbital pain, swelling, redness, tenderness, and impaired eye movement when the infection involves the orbit.
When to use this code
Use H05.02 when the clinician specifically diagnoses osteomyelitis of the orbit. It is appropriate when imaging, operative findings, or specialist notes support bone infection in the orbital area. If the chart only says orbital cellulitis or abscess, check documentation before assigning this code.
Do not use for
Do not use this code for superficial eye infections, conjunctivitis, or nonspecific orbital inflammation. If the record does not confirm bony involvement, check documentation.
Coding tip
Look for explicit mention of orbital bone infection or osteomyelitis in the provider note before coding H05.02.
