ICD-10 Code H05.83 – Thyroid Orbitopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.83 – Thyroid orbitopathy
What it is
H05.83 identifies thyroid orbitopathy, an eye and orbital disorder associated with thyroid disease. It refers to inflammatory changes around the eyes that can affect appearance and function.
Clinical signs
Common findings include bulging eyes, eyelid retraction, redness, swelling, and eye discomfort. Clinical features vary; refer to documentation for laterality and severity.
When to use this code
Use this code when the record documents thyroid orbitopathy, Graves orbitopathy, or thyroid eye disease affecting the orbit. Code it when the provider links the orbital findings to thyroid disease. If the note only says eye redness or proptosis without that diagnosis, check documentation.
Do not use for
Do not use it for nonspecific orbital swelling, conjunctivitis, or other eye disorders without thyroid orbitopathy documented. Check documentation if the diagnosis is uncertain or if another orbital condition is named.
Coding tip
Look for provider wording that connects the orbital findings to thyroid disease before assigning H05.83.
