The decision states face of whether to expand Medicaid to non-disabled, working-age, childless adults—the Affordable Care Act primary expansion population—involves tradeoffs. These tradeoffs include higher taxes, reduced spending on items like education, transportation, or infrastructure, or reduced spending on other Medicaid populations such as the disabled, children, or the elderly. The ACA funding formula allows states to pass a much greater share of the costs of covering non-disabled childless adults to federal taxpayers, but the tradeoffs still exist.

On Sunday, January 17—hours before the Democratic presidential debate on NBC—Vermont Senator Bernie Sanders released details of his proposal to replace the entire U.S. health care system with a universal, government-run, single-payer one. In Sanders’ eight-page campaign white paper, entitled “Medicare for All,” the self-described “democratic socialist” outlines his plan’s core principles.

Warren Gunnels, Sanders’ policy director, retained Gerald Friedman, an economist at the University of Massachusetts at Amherst, to come up with a fiscal score of the Sanders plan. Friedman estimates that the plan would require $13.8 trillion in new government spending in the decade spanning 2017 through 2016. Avik Roy of the Manhattan Institute outlines why that estimate is far too low.

While Democrats are quite eager to point out that ObamaCare has reduced the number of uninsured by 17.6 million, they have conveniently failed to point out that in 2014, American taxpayers effectively paid about $6,000 for each person who became newly covered due to ObamaCare.

Is it really worth reducing worker wages by $1,200 apiece just to cover 2.3 million young adults? And leaving aside all the chaos created by millions of cancelled policies, premium increases paid by tens of millions who received no taxpayer subsidies whatsoever to soften the blow and similar market dislocations, are ObamaCare defenders really prepared to claim that it is worth paying $6,000 apiece to reduce the ranks of the uninsured?

President Obama is proposing to boost federal funding for states that choose to expand Medicaid under ObamaCare in a new effort to entice states to make the move.

Obama will propose in his 2017 budget to have the federal government pick up the entire cost of expansion for three years, no matter when a state decides to accept the expansion.

Under current law, states only got three years of full federal funding if they accepted the expansion in 2014. If nothing changes, states newly accepting the expansion would not get full federal funding after 2016 and instead would get payments that are somewhat less, eventually dialing back to 90% of costs.

The flurry of budget deals struck by congressional Republicans with President Obama in the final months of 2015 will increase the federal debt by hundreds of billions of dollars in the coming decade. They also make it clear that the true state of U.S. fiscal policy is far worse than shown in official projections — which are based on policies that are not going to survive over the long run.

James C. Capretta of the Ethics and Public Policy Center explains how the budget deals will affect the implementation of ObamaCare and ultimately the U.S. economy.

About 1.4 million households that got financial help for health insurance under President Barack Obama’s law failed to properly account for it on their tax returns last year, putting their subsidies at risk if they want to keep coverage. The preliminary figures were released by the IRS late Friday afternoon, a time when the government often reports unfavorable developments.

The Obama administration wasn’t able to ensure that all tax-credit payments made to insurers under the health law in 2014 were on behalf of consumers who had paid their premiums, according to a federal oversight agency. The Health and Human Services’ Office of Inspector General released the report Wednesday. The findings raise questions about the oversight of tax-credit payments that went to insurers on behalf of consumers who qualified for financial assistance.

Are New Yorkers looking at a health insurance tax to pay for the more than $200 million in unpaid doctor and hospital bills remaining after the collapse of the state’s consumer-run nonprofit insurance co-op? Or could that money come from the billions in bank settlements that have flowed to state coffers in recent years?

Those are among the questions that lawmakers and Gov. Andrew Cuomo will likely be debating in the upcoming legislative session. Also unclear is the future status of the approximately 215,000 New Yorkers who had low-cost health insurance policies through the short-lived Health Republic co-op.

The Department of Health & Human Services’ Office of the Inspector General found that the Centers for Medicare & Medicaid Services (CMS):

• Did not have an effective process in place to ensure that advance premium tax credit (APTC) payments were made only for enrollees who had paid their monthly premiums; instead, CMS relied on each qualified health plan (QHP) issuer to verify that enrollees paid their monthly premiums and to attest that APTC payment information that the issuer reported on its template was accurate; and

• Had sole responsibility for ensuring that APTC payments were made only for confirmed enrollees and did not share these data for enrollees with the IRS when making payments.

The OIG determined that CMS’s processes limited its ability to ensure that APTC payments made to QHP issuers were only for enrollees who had made their premium payments.

According to the Department of Health and Human Services, half the uninsured who are eligible for subsidized coverage through the exchanges have refused to purchase it. As a result, those remaining in the insurance pool have tended to be sicker and older — and they’ve used more health services than insurers expected.

How much more? According to the consulting firm McKinsey & Co., insurers collectively swallowed $2.5 billion in unexpected medical expenses from exchange enrollees in 2014.
