Medicare Part D: A Law's Evolution And Impact

Medicare Part D, also known as the Medicare prescription drug benefit, was signed into law by President George W. Bush on December 8, 2003. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 established a new optional Medicare prescription drug benefit program, augmenting the limited coverage of certain outpatient prescription drugs, biologicals, and vaccines currently covered under the original Medicare program. The new program went into effect on January 1, 2006.

Medicare Part D is an optional program

The program offers two types of prescription drug coverage: a standard coverage benefit package and an alternative prescription drug coverage. The standard coverage package includes a deductible, cost-sharing, and access to negotiated drug prices. The alternative prescription drug coverage offers at least actuarially equivalent benefits to the standard package but allows PDPs or MA plans to provide a different prescription drug benefit design.

Beneficiaries can choose to keep their current Medicare fee-for-service coverage and receive qualified prescription drug coverage through enrollment in a PDP or enroll in the MA program, giving up their current Medicare fee-for-service coverage to receive qualified prescription drug coverage under the plan along with basic and possibly enhanced medical coverage.

Medicare Part D is optional for MA enrollees as well. MA enrollees can receive qualified prescription drug coverage through enrollment in an MA-PD plan, keep their current MA plan if it does not provide qualified prescription drug coverage, or enroll in a PDP.

The program is administered by private plans approved by the federal government, with drug benefits provided by private insurance plans that receive premiums from both enrollees and the government. Part D plans typically pay most of the cost for prescriptions filled by their enrollees but are reimbursed for much of this cost through rebates paid by manufacturers and pharmacies.

It helps Medicare beneficiaries pay for self-administered prescription drugs

Medicare Part D, also known as the Medicare prescription drug benefit, is an optional federal-government program to help Medicare beneficiaries pay for self-administered prescription drugs.

Medicare Part D was enacted as part of the Medicare Modernization Act of 2003 and went into effect on January 1, 2006. Under the program, drug benefits are provided by private insurance plans that receive premiums from both enrollees and the government. Part D plans typically pay most of the cost for prescriptions filled by their enrollees. However, plans are later reimbursed for much of this cost through rebates paid by manufacturers and pharmacies.

Part D enrollees cover a portion of their own drug expenses by paying cost-sharing. The amount of cost-sharing an enrollee pays depends on the retail cost of the filled drug, the rules of their plan, and whether they are eligible for additional Federal income-based subsidies.

Prior to 2010, enrollees were required to pay 100% of their retail drug costs during the coverage gap phase, commonly referred to as the "doughnut hole.” Subsequent legislation, including the Affordable Care Act, “closed” the doughnut hole from the perspective of beneficiaries, largely through the creation of a manufacturer discount program.

In 2019, about three-quarters of Medicare enrollees obtained drug coverage through Part D. Program expenditures were $102 billion, which accounted for 12% of Medicare spending. Through the Part D program, Medicare finances more than one-third of retail prescription drug spending in the United States.

To enroll in Part D, Medicare beneficiaries must also be enrolled in either Part A or Part B. Beneficiaries can participate in Part D through a stand-alone prescription drug plan or through a Medicare Advantage plan that includes prescription drug benefits.

Medicare beneficiaries who delay enrollment into Part D may be required to pay a late-enrollment penalty. In 2019, 47 million beneficiaries were enrolled in Part D, which represents three-quarters of Medicare beneficiaries.

It was enacted as part of the Medicare Modernization Act of 2003

Medicare Part D, also known as the Medicare Prescription Drug Benefit, was enacted as part of the Medicare Modernization Act of 2003. The Act was signed into law by President George W. Bush on December 8, 2003, and the Medicare Prescription Drug Benefit went into effect on January 1, 2006.

The Medicare Modernization Act of 2003 was a significant piece of legislation that made the biggest changes to the Medicare program in 38 years. The Act expanded Medicare to include an optional prescription drug benefit, known as Part D, and introduced Medicare Advantage Plans, sometimes called "Part C" or "MA Plans".

The Act also introduced a discount card program, which was in place from 2004 until the Medicare Prescription Drug Benefit went into effect in 2006. The discount card program was designed to help Medicare beneficiaries access prescription drug discounts.

It went into effect in 2006

On July 30, 1965, President Lyndon B. Johnson signed into law the bill that led to the Medicare and Medicaid programs. The original Medicare program included Part A (Hospital Insurance) and Part B (Medical Insurance). Over the years, Congress has made changes to Medicare.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) made the biggest changes to the Medicare in the program in 38 years. Under the MMA, private health plans approved by Medicare became known as Medicare Advantage Plans. These plans are sometimes called "Part C" or "MA Plans."

The MMA also expanded Medicare to include an optional prescription drug benefit, "Part D," which went into effect in 2006.

Beneficiaries can participate in Part D through a stand-alone prescription drug plan or through a Medicare Advantage plan that includes prescription drug benefits. Beneficiaries can enroll directly through the plan's sponsor or through an intermediary. Medicare beneficiaries who delay enrollment into Part D may be required to pay a late-enrollment penalty.

Part D benefits are provided through private plans approved by the federal government. The number of offered plans varies geographically, but a typical enrollee will have dozens of options to choose from. Although plans are restricted by numerous program requirements, plans vary in many ways. Among other factors, enrollees often compare premiums, covered drugs, and cost-sharing policies when selecting a plan.

Medicare offers an interactive online tool that allows for comparison of coverage and costs for all plans in a geographic area. Plans are required to submit biweekly data updates that Medicare uses to keep this tool updated throughout the year.
