Intermittent exophthalmos, right eye

This code signifies the presence of intermittent protrusion of the right eyeball, a condition where the exophthalmos is not constant but rather fluctuates. It indicates a temporary or episodic bulging of the eye, distinguishing it from persistent or fixed exophthalmos.

Apply this code when documentation explicitly states "intermittent exophthalmos" affecting the right eye. This is appropriate for conditions like thyroid eye disease where proptosis may vary, or in cases of orbital masses causing fluctuating pressure. Supporting documentation should clearly indicate the episodic nature and laterality.

• Differentiate from constant exophthalmos (H05.21-) and other orbital disorders.
• Ensure documentation specifies "intermittent" and "right eye" to support this specific code.
• Code the underlying cause of the exophthalmos first, if known, such as thyroid eye disease (E05.00).
