Academy’s Uccello Testifies Before Congress on Affordable Care Act’s Risk-Sharing Mechanisms

WASHINGTON—Cori Uccello, senior health fellow of the American Academy of Actuaries, provided members of the U.S. House Committee on Oversight and Government Reform’s Subcommittee on Economic Growth, Job Creation and Regulatory Affairs with an objective actuarial assessment of the three Affordable Care Act (ACA) risk-sharing mechanisms in testimony before the subcommittee today.

“Millions of Americans have obtained health insurance under the Affordable Care Act. However, the law poses some financial risks for insurers, which could limit competition and plan choice for consumers. To address these risks, the ACA includes three risk-sharing programs — risk adjustment, reinsurance, and risk corridors,” Uccello told members of Congress.

The ACA is expanding access to health insurance coverage, but it does not necessarily establish universal participation. The three mechanisms are designed to mitigate risks such as adverse selection, and insurers’ uncertainty in pricing plans accurately during the early years of the exchanges.

In her testimony, Uccello explained how each of the three mechanisms mitigates risks. “The risk adjustment and reinsurance programs reduce the incentives for insurers to avoid high-cost enrollees,” Uccello said. “And by limiting insurer losses due to pricing uncertainty, risk corridors encourage insurer participation in the market, which in turn increases competition and plan choice. And because the risk corridors are two-sided, the federal government will receive payments from insurers if their gains exceed the threshold.”
