Health Insurance Exchanges Still Face Legislative, Economic Challenges
Confirmation of the Affordable Care Act's constitutionality by the Supreme Court was just the beginning for health insurance exchanges. As timelines grow closer, major barriers to implementation still exist.
Despite confirmation of the Affordable Care Act’s (ACA) constitutionality by the Supreme Court, health insurance exchanges (HIX) still face many legislative and economic barriers.
Another concern that has been discussed in recent weeks is the size of certain HIX. Dana P. Goldman, Director of the Leonard D. Schaeffer Center for Health Policy and Economics at the University of Southern California; Michael Chernew, Co-Editor in Chief of The American Journal of Managed Care; and Anupam Jena, Professors of Healthcare Policy at Harvard University
Economic theory is clear about its indispensable benefits. But not all health care markets are composed of rational, well-informed buyers and sellers engaged in commerce…So the question is: What effect does insurer competition have in a marketplace with so many imperfections?
The evidence is mixed, but some of it points to a counterintuitive result: more competition among insurers may lead to higher reimbursements and health care spending, particularly when the provider market — physicians, hospitals, pharmaceuticals and medical device suppliers – is not very competitive.
The researchers went on to provide concrete examples that speak to the instability of a market with so many unpredictable variables. For instance, despite having two insurers control more than 90% of the market in 2001, Hawaii’s average premium rose only 72% over the next decade. Conversely, Virginia, a state rampant with competition in the health insurance market (the top two providers only controlled 25% of the market in 2001), saw premiums increase 140% on average over the same time span. As Goldman, Chernew, and Jena mentioned, “In financial markets, we ask if banks are too big to fail. When it comes to healthcare, perhaps we should ask if insurers are too small to succeed.”
