An experiment to comprehensively redesign advanced primary care is showing signs of progress, the CMS said Monday in announcing the results of the second performance year of its Comprehensive Primary Care initiative.Of the 481 participating practices, 95% met quality of care requirements and four of seven regions shared in savings, according to the CMS. In 2015, the program generated $57.7 million in gross savings across Medicare Parts A and B -- slightly less than the $58 million the CMS paid out in care management fees.
