Why 'Rate Shock' Is An Essential Part Of Health Care Reform

Once Obamacare is implemented, America's health insurance system will be a thicket of subsidies and transfers that benefit some people and harm others.

Critics of the law have seized on this observation, noting the existence of "rate shock": some people (especially young and healthy ones with moderate and high incomes who buy insurance in the individual market) will pay more than they used to, so others can pay less.

But here's the thing: Before Obamacare, our health insurance system was already a thicket of subsidies and transfers. The law doesn't simplify the system, but it does make the thicket of subsidies and transfers more sensible: directed more at people who have low incomes or high health needs, and greatly shrinking the share of the population that doesn't have health coverage at all.

Making the thicket more sensible will mean that some people's costs go up, producing "rate shock."

Take a look, for example, at Sen. Ted Cruz (R-Texas). Cruz has frequently noted that he declines the health plan that is offered to him as a member of Congress. Instead, he is covered through insurance that his wife gets as a Managing Director at Goldman Sachs.

Health care economist Austin Frakt ran the numbers on that Goldman plan. As of 2009, Goldman's health insurance coverage for employees at the managing director level and higher cost a stunning $40,000 per family. (The typical cost for a family health insurance plan in the United States is around $16,000).

Health insurance benefits are not taxable income, so Cruz and his wife get a big tax break on that plan. The break cut their tax bill by about $15,000 as of 2009, the last year for which we know the plan's value. The Cruzes aren't alone; every American who gets health insurance coverage through work gets this tax break, but the Cruzes enjoy an especially large one because their plan is so expensive and their tax rate is high.

For comparison, Medicaid coverage for two adults and two children cost about $11,000 in 2010, meaning (unless Goldman has radically changed its health benefits since 2009) Cruz is getting a tax break worth more than the benefits a family on Medicaid gets — even though he is a Senator and his wife is a highly paid investment banker and they have no need for subsidies to obtain health coverage.

This is insane health policy, and the Affordable Care Act changes it.

Starting in 2018, the law will impose a "Cadillac Tax" on high-cost health plans of the sort the Cruz family enjoys. The 40% tax on the portion of family plan premiums exceeding $27,500 will serve partly to raise revenue by offsetting the income tax exclusion for insurance. It will also encourage firms like Goldman to offer less-generous plans (which will reduce upward pressure on health care prices) and pay more of their employees' compensation as taxable salaries (producing additional new revenue).
