ICD-10 Code H05.029 – Osteomyelitis of unspecified orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.029 – Osteomyelitis of unspecified orbit
What it is
H05.029 identifies osteomyelitis involving the orbit when the site is not further specified. Use it for documented bone infection of the orbital region without laterality or more precise location.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include orbital pain, swelling, redness, tenderness, and imaging evidence of bony infection. Confirm that the diagnosis is specifically osteomyelitis of the orbit.
When to use this code
Use this code when the provider documents osteomyelitis of the orbit and does not identify the affected side or a more specific orbital site. It is appropriate for confirmed orbital bone infection in the absence of additional detail. If the record names a more specific orbital location, code that instead.
Do not use for
Do not use it for nonspecific orbital cellulitis, sinusitis, or soft tissue infection without bone involvement. Check documentation if the record does not clearly state osteomyelitis.
Coding tip
Code the highest level of specificity available; if laterality or a more exact orbital site is documented, do not default to unspecified.
