ICD-10 Code H05.831 – Thyroid orbitopathy, right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.831 – Thyroid orbitopathy, right orbit
What it is
This code identifies thyroid orbitopathy affecting the right eye socket. Use it when the record specifies thyroid-related eye disease limited to the right orbit.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include eye prominence, eyelid retraction, swelling, or restricted eye movement on the right side.
When to use this code
Use H05.831 when the provider documents thyroid orbitopathy in the right orbit, including Graves-related eye disease or thyroid-associated ophthalmopathy. Code it only when laterality is clearly stated. If the note is nonspecific, check documentation for side and diagnosis wording.
Do not use for
Do not use this code for thyroid disease without orbital involvement, or for eye swelling from another cause. If the record does not specify the right orbit, choose a more general or different laterality code.
Coding tip
Confirm both the thyroid orbitopathy diagnosis and right-side laterality in the provider note before assigning H05.831.
