Thyroid orbitopathy, bilateral

This code signifies an inflammatory disorder affecting the tissues around both eyes, specifically linked to thyroid dysfunction. It is characterized by symptoms such as proptosis (bulging eyes), periorbital edema, diplopia, and restricted eye movement, impacting both orbits.

Apply this code when documentation clearly indicates thyroid-related eye disease affecting both eyes. This diagnosis is typically made by an ophthalmologist or endocrinologist based on clinical examination, imaging (e.g., MRI or CT scans of the orbits), and laboratory findings confirming thyroid disease.

• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code or unspecified code may be more appropriate.
• Always code the underlying thyroid condition (e.g., Graves' disease, E05.00) first, as thyroid orbitopathy is a manifestation of the endocrine disorder.
• Distinguish from other causes of proptosis or orbital inflammation that are not thyroid-related.
