From Health Affairs:
For 2013 and 2014, the federal government raised payment rates to Medicaid primary care providers. Only some states plan to extend the rate increase.
Section 1202 of the Affordable Care Act (ACA) required states to raise
Medicaid primary care payment rates to Medicare levels in 2013 and 2014,
with the federal government paying 100 percent of the increase. This
provision–often referred to as “Medicaid primary care parity” or the
“Medicaid primary care fee bump”–was intended to encourage primary care
physicians to participate in Medicaid, particularly in the face of an
expected increase in enrollment as a result of the ACA’s expansion of
Federal lawmakers failed to reauthorize the fee bump during the 113th
Congress, ending in December 2014. As a result, states must decide
whether to revert to previous primary care payment levels or continue
at a higher level but without the benefit of the enhanced federal match.
