ICD-10 Code H05.033 – Periostitis of bilateral orbits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.033 – Periostitis of bilateral orbits
What it is
H05.033 identifies inflammation of the periosteum around both orbits, the bony eye sockets. Use it when documentation specifically states periostitis affecting both sides.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include orbital pain, tenderness, swelling, or signs of local inflammation around the eyes.
When to use this code
Use this code when the provider documents periostitis of both orbits, including bilateral orbital inflammation or periosteal involvement. It is appropriate when the diagnosis is confirmed in the record and no more specific cause is documented. Check documentation if laterality is unclear.
Do not use for
Do not use this code for nonspecific eye pain, sinusitis, or orbital cellulitis unless periostitis is documented. If the record does not clearly state bilateral orbital periostitis, check documentation.
Coding tip
Verify laterality carefully; this code is specific to bilateral involvement and should not be assigned for unilateral or unspecified orbital disease.
