UPDATED: This analysis was originally published on March 14, 2016. It has since been updated on May 9, 2016 to reflect updated estimates of the costs of repealing the Affordable Care Act (“Obamacare”) and a Medicaid block grant proposal from the proposed FY 2017 House Republican budget. You can view the original analysis here: http://www.crfb.org/blogs/analysis-donald-trumps-health-care-plan-archive/

Republican presidential candidate Donald Trump recently released a health care reform plan entitled “Healthcare Reform to Make America Great Again.” This plan has two major components. First, it would fully repeal the Affordable Care Act (“Obamacare”) and replace it with several new policies. Second, it would turn Medicaid into a “block grant” program.

By our estimates, Mr. Trump’s plan to repeal and replace Obamacare would cost roughly $330 billion over ten years including estimates of faster economic growth, and $550 billion under conventional scoring.

The policies would cause almost 21 million people to lose their insurance coverage, as the replacement health care policies would only cover 5 percent of the 22 million individuals who would lose coverage upon the repeal of Obamacare. This would almost double the number of Americans without health insurance.

Block granting Medicaid, meanwhile, could have a wide range of savings depending on details which have yet to be provided. Past proposals have often saved several hundred billions of dollars.

The Cost of Repealing and Replacing Obamacare

In total, we estimate Mr. Trump’s “repeal and replace” plan for Obamacare would cost nearly $550 billion over ten years under conventional scoring and about $330 billion with dynamic scoring.

The largest component of this estimate comes from the “repeal.” The campaign website proposes to “completely repeal Obamacare,” which we assume to mean repealing the Affordable Care Act’s regulations, subsidies, Medicaid expansion, Medicare savings, and tax increases. Although repealing the coverage provisions would save about $1.1 trillion, based on Congressional Budget Office (CBO) estimates (adjusted for recent legislation and changes in the budget window), repealing the legislation’s tax increases and Medicare cuts would cost a combined $1.6 trillion. In total, this means repeal would cost $480 billion – or $260 billion including the economic benefits of repeal.

Meanwhile, Mr. Trump’s plan to replace Obamacare would entail further costs. Most significantly, Mr. Trump would create a tax deduction for individuals buying their own health insurance. This would equalize the tax treatment between individually-purchased and employer-provided health insurance, but at a cost of roughly $100 billion over ten years.

The cost of these policies would partially be offset by savings from expanding prescription drug importation and re-importation and allowing people to purchase insurance across state lines. Policies to require price transparency and promote health savings accounts will likely have small effects in opposite directions, roughly canceling each other out.1 As a result, the replacement plan would cost $70 billion.

The total cost of Mr. Trump’s repeal and replace health care plan would be $330 billion over a decade under dynamic scoring and $550 billion under conventional scoring. Those numbers would be smaller (and the direction could differ) if he retained some of the Medicare cuts and/or tax increases from Obamacare

Note that this analysis does not include Mr. Trump’s call to negotiate aggressively for Medicare drugs, a policy that is not listed on his website. He has previously claimed that $300 billion a year could be saved through negotiation, a claim we rated as false because Medicare will only spend an average of $111 billion each year on prescription drugs. Based on previous estimates by CBO, actual savings would likely be small or negligible.

The Coverage Impact of Repealing and Replacing Obamacare

According to CBO, about 27 million Americans will lack health insurance coverage in 2018. Repealing Obamacare would increase that number by 22 million, whereas Mr. Trump’s replacement plan would only increase coverage by 1.1 million. In other words, the plan would increase the number of uninsured individuals by about 21 million and only cover about 5 percent of individuals that would lose coverage from Obamacare repeal.

The 1.1 million of gained coverage comes from the policies to allow insurance companies to sell across state lines, which would increase coverage by 400,000, and the deduction for individual health insurance, which would increase coverage by 700,000. (Estimates from CBO) Other elements of Mr. Trump’s replacement plan might reduce costs but would not significantly impact coverage.2

Note that these estimates do not account for Mr. Trump’s call to require insurance companies to cover individuals with pre-existing conditions – a policy not listed on his website. Doing so without penalties or subsidies to encourage individuals to purchase insurance, according to CBO, would actually further increase the number of uninsured individuals.

Block Granting Medicaid

In addition to repealing and replacing Obamacare, Mr. Trump proposes to transform Medicaid into a block grant to the states. Effectively, this means replacing the current system where the federal government pays for a portion of state Medicaid costs (based on a matching rate) with a system where the federal government gives each state a fixed allotment of dollars each year.

Not surprisingly, the amount of money this proposal would save (or cost) depends entirely on the size of that allotment, and how much it grows each year. For example, block grants could be designed to maintain current projected spending levels, or they could be designed to save hundreds of billions of dollars (this year’s FY 2017 House budget resolution assumed over $1 trillion in Medicaid savings). However, the Trump campaign has not provided any information on the size of their proposed block grants, making it impossible to score any savings.

To offer some examples, we assumed block grants would be offered at current levels (excluding the Obamacare expansion) in 2017 but then indexed to grow more slowly than current law. Indexing block grants to per person Gross Domestic Product would only save $25 billion over the next decade; freezing block grants in nominal dollars would save nearly $850 billion. Practically any combination is possible.

If Mr. Trump intends to generate aggressive savings from block granting Medicaid, it could more than pay for the cost of repealing and replacing Obamacare – though perhaps at the cost of a further reduction in coverage.

As our analysis above shows, Mr. Trump’s plan to repeal and replace Obamacare – based on the details available – would both add to the deficit and significantly reduce coverage. Meanwhile, his plan to block grant Medicaid could generate significant savings; however, insufficient details are available to estimate if there are any and how much.

These changes are for the most part in addition to Mr. Trump’s other policy proposals, which we’ve estimated would cost $12.1 trillion, driving debt to 129 percent of the economy in ten years. As the campaign proceeds, we hope that Mr. Trump will present additional policies to pay for his proposals and put debt on a more sustainable path.

Mr. Trump also has proposed to promote price transparency to allow individuals to shop for the best price for each procedure and to promote health savings accounts (HSAs). With regards to price transparency, the Congressional Budget Office found that the effect on prices would be ambiguous, and in our view savings would likely be positive but small. In terms of HSAs, it is not clear how Mr. Trump’s policies would differ from current law. His website says that his plan would “allow individuals to use health savings accounts” and that contributions should be tax-free, allowed to accumulate, and available to family members without penalty. All of these items are already true under current law, and Mr. Trump’s additional proposal to allow HSAs to be passed to heirs will likely have a very small cost. If he intends to expand these accounts so that individuals without high-deductible plans could use them or to increase the limit on contributions, the proposal could have significant costs. However, we assume only a small cost based on the ideas specifically articulated in the press and scores of previous modest HSA proposals.

Mr. Trump also says that “We must review basic options for Medicaid and work with states to ensure that those who want healthcare coverage can have it.” However, without any specific proposals, it is not clear what changes, if any, are being proposed. Although we reached out to the Trump campaign, they did not provide us with any detail on this or other policies. Thus, we did not include this in our coverage estimates.
