Constant exophthalmos, right eye

This code describes a persistent protrusion of the right eyeball from the orbit. This condition is often associated with thyroid eye disease (Graves' ophthalmopathy) but can also result from orbital tumors, inflammation, or trauma.

Apply this code when documentation clearly indicates a sustained, outward displacement of the right eye. This is appropriate for patients presenting with unilateral exophthalmos affecting the right eye, regardless of the underlying etiology. Supporting documentation should specify the laterality and chronicity of the exophthalmos.

• Ensure documentation specifies "constant" or "persistent" exophthalmos to differentiate from intermittent or transient protrusion.
• Always code the underlying cause of the exophthalmos if known and documented (e.g., E05.00 for Graves' disease with hyperthyroidism).
• Do not confuse with H05.242 (left eye) or H05.243 (bilateral) exophthalmos.
