Z808 – Progressive carotid occlusion by Selverstone clamp

OHIP Psychiatric Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits

Progressive carotid occlusion by Selverstone clamp is a surgical procedure listed in the Neurological Surgical Procedures section of the Schedule. It involves the gradual closure of the carotid artery. This service includes all common and specific elements applicable to a surgical procedure, including pre-operative and post-operative care as defined in the Schedule of Benefits on pages to .

When to Use

Use Z808 specifically for the surgical placement of a Selverstone clamp to facilitate gradual carotid artery occlusion, distinct from the definitive repair or endarterectomy procedures like R792.
Apply this code when the clinical intent is a staged, controlled reduction of blood flow rather than an acute surgical bypass or vessel reconstruction.

Common Pitfalls

Billing Z808 in conjunction with R792 for the same vessel is a common audit trigger, as these procedures represent different surgical approaches to carotid pathology.
Attempting to bill a hospital admission assessment as a separate service is prohibited; only the major pre-operative decision-making visit is eligible alongside this surgical fee.

Billing Tips

Ensure that the operative report explicitly details the use of the Selverstone clamp to justify the use of Z808 over other vascular surgical codes.
Verify that all relevant surgical assistant and anaesthesiologist premiums are applied, as Z808 is a complex neurological procedure eligible for standard surgical add-ons.
