The survey found that provider rate restrictions was the most frequently reported cost containment strategy, with 39 states restricting rates in 2011 and 46 reporting plans to do so in 2012. Several states also increased or imposed new provider taxes that can generate more federal matching revenue and help mitigate the effects of cuts to some providers. States focusing on benefit reductions and restrictions have eliminated, restricted, or reduced Medicaid benefits in areas such as dental care, medical supplies, durable medical equipment, and personal care services. Almost all states have been making substantial changes in Medicaid pharmacy programs, the survey found, including preferred drug lists, supplemental rebates, and prior authorization requirements, and states are now focusing on controlling costs for specialty drugs, a rising share of prescription drug spending.
