Health status and access to care improved for Medicaid patients when the Affordable Care Act mandated a temporary rate increase for physicians serving newly insured patients covered through that law’s Medicaid expansion.

But when the mandate for increased physician payments ended and state Medicaid programs reverted to their previous, lower payments, many of those benefits were lost.

Or so reports a new study from the National Bureau of Economic Research.

According to the study, even a $10 rate increase improved access to care enough to reduce by 13 percent Medicaid recipients’ complaints about not being about to find a doctor.  Utilization also increased.  The temporary Medicaid pay increase has even been credited with improving school attendance and reducing chronic absenteeism.

Despite the benefits of the temporary increase in Medicaid payments to physicians, most states returned to lower payments when the mandated ended, most of the gains resulting from the better pay for treating Medicaid patients disappeared, and the disparities between privately insured individuals and Medicaid patients returned to their pre-Affordable Care Act levels.

Researchers estimate that increasing Medicaid payments to physicians by an average of $26 a visit would eliminate disparities in access to care.

These findings are especially relevant to private safety-net hospitals because the communities they serve have so many more Medicaid patients than the typical American community.
