Medicare Advantage Growth Highlights Cost-Benefit Tradeoffs
Enrollment in Medicare Advantage plans has surged from 8 million to 33 million since 2007, driven by lower premiums and expanded benefits. Private insurers achieve these cost savings through restricted provider networks and prior authorization requirements—tools that limit physician choice for enrollees.
While Advantage plans cover services like vision and dental care absent in traditional Medicare, KFF research reveals enrollees access just 48% of available physicians compared to traditional Medicare. The tradeoff between affordability and provider access defines this market shift.
