ICD-10 Code H05.023 – Osteomyelitis of bilateral orbits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.023 – Osteomyelitis of bilateral orbits
What it is
This code identifies osteomyelitis affecting both orbits, meaning infection and inflammation involve the bony eye sockets on both sides. Use it when documentation clearly states bilateral orbital bone infection.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include orbital pain, swelling, redness, tenderness, or impaired eye movement, but you should code only when the record supports bilateral orbital osteomyelitis.
When to use this code
Use H05.023 when the provider documents osteomyelitis of both orbits, or when imaging, operative notes, or specialist assessment confirms bilateral orbital bone infection. If the record only says “orbital infection” or “cellulitis,” check documentation before assigning this code.
Do not use for
Do not use this code for preseptal or orbital cellulitis, soft-tissue orbital abscess, or unspecified eye infection. If laterality is not bilateral, or the diagnosis is uncertain, check documentation.
Coding tip
Verify both the anatomic site and laterality in the provider note before coding; “orbit” alone is not enough for H05.023.
