Colleen, I did this exam in a private office with a complete TCD, monotoring and with BH. I only have access to a TCD nonimaging system. I did studies in the past with maneuvering so added it to the exam. So the end result is I cannot bill for the exam since we charged for all the exams that I mentioned.
Thank you and great to hear from an expert.
My best to you and staff at Swedish.

Charges depend on your protocol.  A limited carotid to assess the extracranial vertebral arteries bilaterally should be performed since patients who are positive frequently only have one functional vertebral, the other either occluded/severely stenosed or congenitally small.  A limited TCD is also performed to assess the intracranial vertebral and basilar arteries. TCD Imaging of the posterior cerebral arteries will help rule out fetal origin PCA’s which, if present will preclude doing the study at all (unless you try to monitor the extracranial verterbral arteries during head positioning).  The bilateral PCA’s are then monitoring using a head band with provocative head positioning.  This is a tedious test indeed but for the few patients who have this syndrome can definitely direct their management and if done correctly rule out extrinsic compression.  We charge a limited carotid and a limited TCD.  Below is a good reference article; I tried to attach it but the Flownet rejected the email because of the attachment.
