Optimizing utilization of sacubitril/valsartan for treatment of heart failure could improve provider performance in the Bundled Payments for Care Improvement initiative and the Medicare Shared Savings Program.

Formulary restrictions on brand name noninsulin antihyperglycemic drugs have little impact on treatment intensification patterns among low-income patients with diabetes in Medicare Part D.
