Medicare will pay for the screening once, when you get a referral for it during the "Welcome to Medicare" visit the first year you have Medicare. http://www.medicare.gov/navigation/manage-your-health/preventive-services/abdominal-aortic-aneurysm.aspx?AspxAutoDetectCookieSupport=1
You also must have a risk factor for an AAA to get the referral (i.e. a family history of AAA, or a male who has smoked at least 100 cigarettes in his lifetime).
If the first screening was negative for AAA there is no reason to have another unless you develop symptoms.
