ICD-10 Code H05.261 – Pulsating exophthalmos, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.261 – Pulsating exophthalmos, right eye
What it is
This code identifies pulsating protrusion of the right eyeball. It usually reflects an abnormal vascular connection or transmitted pulsation behind the eye, so you should document the eye side and underlying cause when known.
Clinical signs
Typical findings include visible forward bulging of the right eye with rhythmic pulsation. Clinical features vary; refer to documentation, and note any associated bruit, orbital mass, trauma history, or vascular abnormality if recorded.
When to use this code
Use H05.261 when the record specifically documents pulsating exophthalmos of the right eye. It is appropriate for outpatient, inpatient, or consult notes when the laterality is clear and the condition is confirmed.
Code it when the provider links the finding to the right eye, even if the exact cause is still under evaluation. Check documentation if the note only says exophthalmos, proptosis, or eye pulsation without laterality.
Do not use for
Do not use this code for unspecified or bilateral exophthalmos, or for simple eye prominence without pulsation. Do not assign it when the chart describes a different orbital disorder; check documentation.
Coding tip
Always verify laterality and whether the record truly says “pulsating” before assigning H05.261.
