Optimal facility in-network selection for healthcare payers under reference pricing

My working paper with Victoire Denoyel and Laurent Alfandari of ESSEC Business School is online! Read it here.

Abstract: "Healthcare payers are exploring cost-containing policies to steer patients, through qualified information and financial incentives, towards providers offering the best value proposition. With Reference Pricing (RP), a payer or insurer determines a maximum amount paid for a procedure, and patients who select a provider charging more pay the difference. In a Tiered Network (TN), providers are stratified according to a set of criteria (such as quality, cost and sometimes location) and patients pay a different out-of-pocket price depending on the tier of their chosen provider. Motivated by a recent CalPERS program, we design two original MIP optimization models for payers that combine both RP and TN, filling the gap of quantitative research on these novel payment policies. Carefully designed constraints provide the decision maker with levers for a trade-off between cost reduction and patients' satisfaction. Numerical experiments provide valuable insights in that respect, displaying also how the tiers are scattered on a cost/quality plane. We argue that this system has strong potential in terms of costs reduction for public or private payers, quality increase for patients and visibility for high-value providers."

To the best of our knowledge, our paper presents the first quantitative model about tiered-networks design for a healthcare procedure under reference pricing, a model the CalPERS pilot study will certainly popularize.

Our paper is here. (Comments welcome!) We're now working on extensions that we hope to share and discuss soon.

If you're interested in learning more in reference pricing for healthcare procedures, I recommend the work of James C. Robinson of UC Berkeley, who led the analysis of the CalPERS pilot, for instance "Payers test reference pricing and Centers of Excellence to steer patients to low-price and high-quality providers" (Health Affairs, subscription required).
