In this study, data showed consumer sensitivity and price differences increased for freestanding and hospital-based facilities when patients were insured with reference-based benefits.
Researchers collected data for 3,962 patients insured by the California Public Employees Retirement System (CaiPERS) who underwent knee or shoulder arthroscopy in January 2012, which was 3 years before the reference-based benefits were implemented. They did the same for 2,505 patients also insured with CaiPERS, who underwent arthroscopy 2 years after reference-based benefits were implemented. The researchers also collected data for 57,791 control patients insured with Anthem who underwent arthroscopy, but were unaffected by reference-based benefits.
