This paper examines how health care providers respond to a reference pricing insurance program that increases consumer cost sharing when consumers choose high-priced surgical providers. We use geographic variation in the population covered by the program to estimate supply-side responses. We find limited evidence of market segmentation and price reductions for providers with baseline prices above the reference price. Finally, approximately 75% of the reduction in provider prices is in the form of a positive externality that benefits a population not subject to the program.
