ICD-10 Code H05.351 – Exostosis of right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.351 – Exostosis of right orbit
What it is
H05.351 identifies a bony outgrowth, or exostosis, located in the right orbit. Use it when documentation specifically states an exostosis affecting the right eye socket.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a palpable or imaging-confirmed bony mass in the right orbital area, sometimes with local prominence or pressure effects.
When to use this code
Use this code when the provider documents exostosis of the right orbit, including radiology or specialist notes that clearly localize the lesion to the right side. It is appropriate for confirmed orbital bony overgrowth, not for vague facial bone findings. Check documentation if laterality is unclear.
Do not use for
Do not use H05.351 for exostosis of the left orbit, unspecified orbit, or non-orbital bony growths. Do not assign it when the record only mentions a suspected mass without confirmation.
Coding tip
Verify laterality and anatomic site in the final diagnostic statement before coding H05.351.
