Pulsating exophthalmos, unspecified eye

This code describes the outward protrusion of the eyeball that visibly pulsates, indicating a vascular abnormality behind the globe. This pulsation is often synchronous with the patient's heartbeat and suggests a direct connection between arterial and venous systems within the orbit.

Use this code when documentation specifies pulsating exophthalmos without further detail regarding the affected eye. This typically occurs in cases of orbital vascular malformations, such as carotid-cavernous fistulas, where the pulsatile nature is a key diagnostic feature. Ensure the medical record clearly states the presence of pulsation.

• Do not use this code if the laterality (right or left eye) is documented; instead, select the more specific code.
• This code is for the symptom of pulsating exophthalmos; additional codes for the underlying cause (e.g., carotid-cavernous fistula) should also be reported.
• Distinguish from non-pulsating exophthalmos, which would be coded differently.
