Mitt Romney’s/Paul Ryan’s premium support/voucher plan was heavily derided during the dark days of Campaign 2012, but the devil was always more in the details than the theory. While the re-election of President Obama left premium support dead on the Medicare level, health insurers are increasingly turning to the ideas that drove it – choice, competition, and the power of a (carefully regulated) market – to address high costs on the procedural level. Call it the micro-voucherization of health insurance.
This is known by wonks as reference pricing, and its recent results in California are promising: the costs of hip and knee replacements fell by 19%, with no attendant decrease in quality. Using reference pricing is an assault on the status quo that holds the promise of “bending the curve” in a meaningful way, but it faces technical and political concerns that may consign it to the graveyard of promising-but-unfulfilled ideas.
Broadly-speaking, reference pricing is the act of offering a set amount of money for the purchase of a good, where the reference is an amount that can reasonably said to offer meaningful coverage for that good. Sometimes, reference pricing is focused on a given procedure – what I’ll refer to as “inputs-oriented reference pricing”; other times, a given outcome, or “outputs-based reference pricing.”
That’s pretty vague, so let’s use the colonoscopy procedure (which has recently received a lot of attention thanks to an informative New York Times article) to help color this in. The inputs-oriented approach would see the payer asking: given the choice to have a colonoscopy – a procedure which varies wildly in cost without varying wildly in quality – what’s a reasonable price to pay? It would decide this based on some combination of price, quality, and geography, and would inform consumers of its spending cap.
Say it finds that most of its insured population can reasonably access a high-quality colonoscopy for $10,000; if a consumer choose provider that charges $15,000, he or she would pay the $5,000 difference out of pocket. Choice is preserved, but at a cost. The simple chart above shows how this may work.
But, if you read the colonoscopy article, you may be asking a separate question: why pay for a colonoscopy at all?
