Which legislation required a significant prescription drug benefit improvement and faster Medicare appeal decisions?

The correct answer is C, which refers to the Benefits Improvement and Protection Act (BIPA) of 2000. This legislation was pivotal in expanding benefits under Medicare, particularly in the context of prescription drugs. It introduced measures that enhanced the prescription drug benefits available to seniors, addressing a critical gap in coverage at that time.

Moreover, BIPA established provisions for quicker appeal processes concerning Medicare decisions. This means that beneficiaries could have faster access to reconsideration of denied claims, significantly improving their overall experience with the Medicare program.

The other legislative options do not address prescription drug benefits in the same way that BIPA does. For instance, TEFRA (Tax Equity and Fiscal Responsibility Act) mainly focused on Medicare payment provisions and increasing revenue for the Medicare system but did not specifically enhance drug benefits. ARRA (American Recovery and Reinvestment Act) was primarily focused on economic stimulus and job creation, while FELA (Federal Employers Liability Act) pertains to railroad workers and their rights, unrelated to Medicare or prescription drugs. Therefore, BIPA stands out as the legislation that introduced significant improvements in prescription drug benefits and expedited the appeals process within the Medicare framework.
