The Committee for a Responsible Federal Budget estimates that Medicare Advantage will be overpaid by $1.2 trillion by the USG between 2025 and 2034. Medicare Advantage plans are private, for-profit health insurance plans that Washington pays to manage Medicare. They are being aggressively being pushed on senior citizens as an alternative to traditional Medicare. These plans cover more than half of the 68.5 million people currently enrolled in Medicare. Former Cigna executive Wendell Potter describes Medicare Advantage as "one of the biggest scams that we've seen in this country."
