ICD-10 Code H05.833 – Thyroid Orbitopathy, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.833 – Thyroid orbitopathy, bilateral
What it is
H05.833 identifies thyroid orbitopathy affecting both eyes. Use it when documentation states bilateral thyroid eye disease, Graves’ orbitopathy, or similar wording tied to both orbits.
Clinical signs
Clinical features may include bilateral proptosis, eyelid retraction, periorbital swelling, and eye discomfort. Findings can also include diplopia or restricted eye movement; refer to documentation if the record is unclear.
When to use this code
Use this code when the provider documents thyroid orbitopathy in both eyes, even if one side is worse. It fits outpatient, inpatient, or specialist notes that clearly identify bilateral orbital involvement. If laterality is not stated, check the record before coding.
Do not use for
Do not use H05.833 for unspecified thyroid eye disease or for unilateral disease. Do not assign it when the note describes another orbital disorder without thyroid involvement.
Coding tip
Confirm bilateral laterality in the assessment or problem list before assigning H05.833.
