Pulsating exophthalmos, bilateral

This code signifies the presence of pulsating exophthalmos affecting both eyes. Pulsating exophthalmos is characterized by a rhythmic, palpable, and often visible protrusion of the eyeball, typically synchronous with the patient's pulse. This condition often indicates an underlying vascular abnormality, such as an arteriovenous fistula.

Use this code when documentation clearly indicates bilateral pulsating exophthalmos. This is commonly seen in cases of carotid-cavernous fistula or other orbital vascular malformations affecting both orbits. Supporting documentation should describe the pulsatile nature of the proptosis and confirm bilateral involvement.

• Ensure documentation specifies "pulsating" and "bilateral" to support this specific code.
• Investigate and code the underlying cause of the pulsating exophthalmos, if known, as a primary or secondary diagnosis.
• Differentiate from non-pulsating exophthalmos (H05.20-H05.25-) and unilateral presentations.
