Americans pay an average of approximately <\/span>$1,200 a year<\/span><\/a> for prescriptions\u2014and that figure represents out-of-pocket costs alone.<\/span><\/p>\n

The rest of the prescription price tag falls to employers and to insurance providers, including federal and state programs such as <\/span>Medicaid<\/span><\/a>, which cover more than 70 million people. Some insist that Medicaid administrators must <\/span>negotiate with drug manufacturers<\/span><\/a>, using their purchasing power to drive down prices. Put simply, Medicaid spending on prescription drugs is both controversial and complicated. We set out to study the data behind the debate.<\/span><\/p>\n

We analyzed Medicaid\u2019s <\/span>State Drug Utilization Data<\/span><\/a>, a comprehensive record of how Medicaid beneficiaries across the country purchase prescriptions. Our findings show which states\u2019 programs are spending the most and which drugs are used most often. To truly understand America\u2019s use of expensive prescriptions, keep reading.\u00a0<\/span><\/p>\n

Medicaid prescription prices and popularity<\/b><\/h2>\n

A small number of medications account for a sizable percentage of Medicaid reimbursements, including prescriptions associated with the treatment of common ailments. Between 2009 and 2018, Medicaid covered 212,663,453 prescriptions for <\/span>amoxicillin<\/span><\/a>, an antibiotic used to treat conditions ranging from pneumonia to urinary tract infections. <\/span>Ibuprofen prescriptions<\/span><\/a> were similarly common, although this medication is also available over the counter. Hydrocodone, a medication used to treat pain, was prescribed 191,159,584 times during the period studied.<\/span><\/p>\n

\"total-scatterplot\"<\/p>\n

In terms of total reimbursement costs, however, Medicaid\u2019s largest bills came from relatively expensive medications designed to treat chronic illnesses. Truvada, which suppresses the symptoms of HIV and prevents transmission of the virus, cost Medicaid $5.8 billion (critics claim the drug\u2019s manufacturer charges <\/span>an exploitative price<\/span><\/a> for its product). Similarly, Suboxone cost Medicaid $6.7 billion between 2009 and 2018, although that sum paid for fewer than 30 million prescriptions. The drug, designed to treat opioid dependence, remains heavily regulated.<\/span><\/p>\n

A Medicaid enrollment explosion<\/b><\/h2>\n

In the years following the passage of the Affordable Care Act, 37 states elected to adopt <\/span>\u201cMedicaid Expansion\u201d plans<\/span><\/a>, extending coverage to millions of Americans who did not qualify previously. As a result, Medicaid participation increased substantially between 2013 and 2017, from 56,533,472 people to 74,775,710. During that period, the program\u2019s prescription reimbursement costs rose by $17 billion as well. Yet, both measures fell slightly in 2018, a development that some <\/span>experts attribute<\/span><\/a> to the robust economy. As workers earn more, they exceed income thresholds for Medicaid coverage, reducing the program\u2019s rolls. Another cause of reduced participation may be new work requirements, which the Trump administration has urged states to implement in recent years.<\/span><\/p>\n

\"enrollment-reimbursement\"<\/p>\n

Many of the nation\u2019s <\/span>most populous states<\/span><\/a> had the largest prescription reimbursement totals. In fact, state-by-state cost differentials were enormous: New York, California, and Texas spent significantly more than the other 47 states combined during the period studied. But with regard to Medicaid spending per capita, New York and California had some of the nation\u2019s lowest costs\u2014less than 15 cents per enrollee. By contrast, a few New England states seemed exceedingly generous: Vermont, Maine, and New Hampshire paid over $3 per enrollee in prescription reimbursements.<\/span><\/p>\n

A surge in scripts for Medicaid participants<\/b><\/h2>\n

As Medicaid enrollment grew between 2013 and 2017, the number of prescriptions obtained through Medicaid also increased significantly. To some extent, these findings are intuitive: As more people participate in the program, the need for medication grows accordingly. Yet, state data adds a layer of complexity to this simple correlation. Some of the nation\u2019s most populous places, including California, New York, Texas, and Florida, averaged less than 0.3 prescriptions for every 1,000 enrollees. At the other end of the spectrum, Vermont\u2019s Medicaid program covered nearly six prescriptions for every 1,000 participants. What might explain these vast geographical differences in medical need?<\/span><\/p>\n

\"enrollment-filled\"<\/p>\n

One explanation for these prescribing patterns may relate to age: Maine, New Hampshire, and Vermont have among the <\/span>oldest state populations<\/span><\/a> by percentage of total population, so average residents may need more medications as a result. But in states on both ends of the per-capita prescription spectrum, local legislators have recognized the impact of pharmaceutical prices on their Medicaid programs. In 2018, Vermont <\/span>became the first state<\/span><\/a> to legalize the importation of prescription drugs from Canada, capitalizing on cheaper prices across the border. In California, Gov. Gavin Newsom directed Medicaid to <\/span>negotiate prescription pricing<\/span><\/a> directly with drug manufacturers in a bid for better terms.<\/span><\/p>\n

Medicaid drug coverage<\/b><\/h2>\n

Many of the drugs most frequently prescribed to Medicaid enrollees did not drive reimbursement costs. But Ventolin HFA (albuterol), a rescue inhaler used to treat asthma, bucked this trend: As the most commonly prescribed medication, it accounted for $10.5 billion in reimbursements. Several less popular asthma medications also proved costly to Medicaid, including Fluticasone and Symbicort. <\/span>Some research<\/span><\/a> indicates that asthma is far more common among children and adults living in lower-income households\u2014and Medicaid is explicitly designed to serve these groups.<\/span><\/p>\n

\"common-costly\"<\/p>\n

Three diabetes medications also cost Medicaid programs more than $4 billion apiece in reimbursements. This finding may also reflect health conditions of lower-income Americans, who have <\/span>far higher rates of diabetes<\/span><\/a> than other socioeconomic groups. Harvoni, a medication proven to treat hepatitis C, accounted for more than $5 billion in reimbursements. Medicaid administrators are deeply concerned that reimbursements for the drug may prove unsustainable. The <\/span>average 12 week course of Harvoni costs $94,500<\/span><\/a>, a rate that would financially burden state Medicaid programs if every enrollee with hepatitis C received this treatment.<\/span><\/p>\n

Highest Medicaid reimbursement costs<\/b><\/h2>\n

For six medications, Medicaid reimbursements exceeded $1,000 per dose on average. The most expensive overall was Synagis, which can help prevent <\/span>respiratory syncytial<\/span><\/a>, a common condition in infants and older adults. Epogen, an anemia treatment, costs $1,857 per dose\u2014a particularly steep price considering that anemia is <\/span>often a side effect<\/span><\/a> of other expensive medical treatments, such as chemotherapy. Two antipsychotic medications, Invega and Risperdal, also proved exceptionally expensive per dose.<\/span><\/p>\n

\"hi-dose\"<\/p>\n

As discussed above, Harvoni was among the most expensive medications per dose, as were three other hepatitis C treatments. Two immunosuppressants, Humira and Remicade, also made this list (Humira can also be self-injected, potentially lowering costs). Meanwhile, Mirena, an intrauterine device designed to prevent pregnancy, cost $758 on average\u2014although this price may actually be lower than the cumulative expense of birth control pills over time. Medicaid prescription coverage for birth control <\/span>remains controversial<\/span><\/a> in some states, but advocates say it reduces program costs in the long run by preventing unplanned pregnancies.<\/span><\/p>\n

Mapping medication<\/b><\/h2>\n

In nearly every state, specific medications were covered exceedingly often by Medicaid. Often, the disproportionate use of a particular pharmaceutical resulted from state health initiatives. In Vermont, for example, prescriptions for Suboxone were 805% higher than the national average: The drug has become an essential part of its <\/span>\u201chub and spoke\u201d<\/span><\/a> model for treating opioid dependence. New Jersey, which has <\/span>emphasized combating diabetes<\/span><\/a> through Medicaid, covered alogliptin prescriptions nearly nine times more often than the national rate. In other cases, state policies seemed to privilege a specific form of a common medication. Oklahoma, for example, covered 562% more Tamiflu prescriptions than the national average. Indiana, meanwhile, was 738% more likely to cover <\/span>oseltamivir<\/span><\/a>, the generic equivalent.<\/span><\/p>\n\n\n
