In 2013, 69% of primary care physicians were accepting new Medicaid patients, as compared to 84% for new Medicare patients and 85% for new privately insured patients. Physicians accept privately insured patients and Medicare patients at higher rates than Medicaid patients, because Medicaid payment rates to doctors are much lower. However, Obamacare temporarily increased Medicaid payment rates to Medicare levels in 2013 and 2014.
