Within the same physician groups, 2-sided risk in Medicare Advantage (MA) was associated with higher quality and lower utilization for dually eligible beneficiaries compared with fee-for-service MA and traditional Medicare.

Physician groups under 2-sided risk–based Medicare Advantage provide care associated with higher quality and efficiency compared with care by these same groups under fee-for-service Medicare.

Medicare beneficiaries treated by physicians with high levels of Medicare Advantage risk exposure had higher care quality and efficiency outcomes compared with those treated by other physicians.
