About The Study: Among patients with commercial insurance, manufacturer-sponsored coupon use declined substantially between 2017 and 2024, whereas per-claim coupon amounts increased. These patterns may reflect several mechanisms. Manufacturers may be concentrating coupon programs on fewer products or for fewer patients while offering larger incentives in response to formulary pressures or expanded copay accumulator programs. Greater coupon amounts may also reflect higher underlying patient cost-sharing requirements.
