Another day, another way to try to save some money on Medicare.

The Obama administration announced Monday a massive pilot program to test a new method of paying primary care physicians for treating Medicare patients. It’s one of a number of initiatives the administration has launched in a broad effort to move Medicare away from the traditional fee-for-service payment model.

The five year pilot will include 20,000 doctors who voluntarily sign up to participate. Half of them will receive about $15 a month for each Medicare patient they oversee, along with a fee for every service they provide. The other half will receive a monthly payment nearly twice as large but will receive smaller fees for services.
