Other members may comment on whether their carotid ultrasound or other Non-Invasive Vascular tests were covered by Medicare, but, as with everything related to Medicare, it must be medically necessary, and that will vary by individual.

I think the best source of information would be Medicare itself. Call the phone number on your insurance card and ask.

Has you provider recommended/ordered the test? If ordered, the health care facility's billing department may be able to give you an estimate, but the final decision is still with Medicare.
