Final answer:
MediGAP plans do not cover the gaps in Part D drug benefits; they are designed for costs not covered by Medicare parts A and B. Medicare Part D, introduced by the Medicare Prescription Drug and Modernization Act of 2003, addresses some prescription drug costs.
Step-by-step explanation:
False: MediGAP plans do not cover the "gaps" in Part D drug benefits. Instead, MediGAP policies are designed to cover costs not covered by Medicare Parts A and B, such as copayments, deductibles, and coinsurance.
Medicare has been criticized for not covering certain expenses, including prescription drugs. This led to the Medicare Prescription Drug and Modernization Act of 2003, which introduced assistance programs, including one where the federal government pays 75 percent of prescription drug costs up to $2,250, after individuals pay an annual premium and deductible. However, this is not part of the MediGAP plans.
