“Despite the president’s assurance that “if you like your health plan, you can keep your health plan,” Obamacare caused significant disruption to people’s coverage as the health insurance exchanges prepared for their first open enrollment. Beginning October 1, 2013, insurers knew they would struggle to price policies in the exchanges accurately.
The Affordable Care Act (ACA) included three mechanisms to backstop insurers’ risks: risk adjustment, reinsurance and risk corridors. The first, risk adjustment, consists of perpetual transfers of money from unexpectedly profitable insurers to unexpectedly loss-making insurers and is — at least conceptually — necessary to mitigate risk in a market where insurers are forbidden to charge beneficiaries actuarially accurate premiums.
The other two mechanisms, reinsurance and risk corridors, were designed to protect insurers from unforeseen losses in Obamacare’s first three years, when insurers would not have enough experience to know how much risk they faced. These financial protections are critical to insurers’ ability to survive in the exchanges through the end of 2016. Both schemes persist only through the first three years of Obamacare, by the end of which its architects believed actuarial risks in the exchanges will have stabilized.”
