Germany's Use Of Reference Pricing For Biologics: Lessons For The US

A redesign of consumer cost sharing in the United States is important to accelerate the adoption of biosimilars and price reductions for biologics. This article analyzes therapeutic reference pricing for anti-inflammatory biosimilars in Germany and its implications for the United States. The German experience demonstrates that a redesign of consumer cost sharing can achieve savings for payers without creating onerous financial barriers for patients. In contrast, the dominant coinsurance structure of cost sharing in the US creates strong incentives for patients to abandon treatment, especially for serious illnesses treated by complex biologics, and only weak incentives to compare prices among therapeutically equivalent products. The Medicare Payment Advisory Commission (MedPAC) has advocated that the Centers for Medicare and Medicaid Services adopt a variant of reference prices for biologics, their related biosimilars, and therapeutically similar branded alternatives by assigning them the same billing code or by paying a similar rate for all the products. The German experience demonstrates that the proposed MedPAC approach is technically feasible and would generate savings for payers without imposing access obstacles on patients.
