Intermittent exophthalmos, left eye

This code describes the episodic protrusion of the left eyeball from the orbit, which may be spontaneous or induced by factors like changes in intraocular pressure or head position. It indicates that the exophthalmos is not constant but occurs intermittently.

Use this code when documentation specifies intermittent proptosis affecting the left eye. This diagnosis is typically supported by physician notes detailing recurrent, non-sustained bulging of the left eye, often observed during specific activities or examinations.

• Ensure the documentation clearly specifies "intermittent" and laterality (left eye).
• Distinguish from constant exophthalmos (H05.21-) or other orbital disorders.
• Code any underlying cause of the intermittent exophthalmos, such as thyroid eye disease, if documented and applicable.
