The GAO did a study:
Medicaid enrollment has grown significantly in recent years due to the economic downturn. This growth is expected to continue as the Patient Protection and Affordable Care Act potentially extends Medicaid eligibility in 2014 to millions of uninsured individuals. To better understand whether states are providing adequate access to medical care for beneficiaries, this report examines (1) states’ experiences processing Medicaid applications, (2) states’ changes to beneficiary services and provider payment rates, (3) the challenges states report to ensure sufficient provider participation, and (4) the extent to which Medicaid beneficiaries reported difficulties obtaining medical care. To examine the first three objectives, GAO administered a nationwide web-based survey to Medicaid officials on states’ experiences from 2008 through 2011 and obtained a response rate of 98 percent. To examine the last objective, GAO analyzed data from the 2008 and 2009 Medical Expenditure Panel Survey, the most current available at the time of our analysis, to assess Medicaid beneficiaries’ reported difficulties obtaining care, and the 2009 National Health Interview Survey to assess their reasons for delaying care. To provide context, we compared their experiences to those of individuals with private insurance or who were uninsured.
Basically, they looked at how states process Medicaid applications, how they have changed their programs, what barriers exist preventing full enrollment, and how often those who get Medicaid say they have trouble getting care. You know, the stuff some people like to say Medicaid is terrible at.
What did they find?
States reported making numerous changes to provider payments, provider taxes, and beneficiary services since 2008. While more states reported provider-rate and supplemental payment increases each year from 2008 through 2011, the number reporting payment reductions and increased provider taxes also grew. More states reported increasing services than limiting them.
And what about access?
In calendar years 2008 and 2009, less than 4 percent of beneficiaries who had Medicaid coverage for a full year reported difficulty obtaining medical care, which was similar to individuals with full-year private insurance; however, more Medicaid beneficiaries reported difficulty obtaining dental care than those with private insurance. Beneficiaries with less than a full year of Medicaid coverage were almost twice as likely to report difficulties obtaining medical care as those with full-year coverage. Medicaid beneficiaries reported delaying care for reasons such as long wait times and lack of transportation.
Not that I expect any of this will be reported widely. Full report here.
