About H05.83

H05.83 is the ICD-10-CM diagnosis code for thyroid orbitopathy. It belongs to category H05 (disorders of orbit), block H00-H05 (disorders of eyelid, lacrimal system and orbit) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within H05.8 (other disorders of orbit), H05.83 is specifically for thyroid orbitopathy. Related codes cover cyst of orbit (H05.81), myopathy of extraocular muscles (H05.82) and other disorders of orbit (H05.89).

To report this condition, pick the subcode that matches the documentation: H05.831 (right orbit), H05.832 (left orbit), H05.833 (bilateral) and H05.839 (unspecified orbit).

It was added in FY2026, effective October 1, 2025.
