Does Medicare Part B Cover Prescription Drugs?

Medicare is a federal health insurance program designed to provide coverage for individuals aged 65 or older, as well as certain younger people with specific disabilities or conditions like permanent kidney failure or Amyotrophic Lateral Sclerosis (ALS). This program is divided into various parts, each tailored to cover distinct healthcare services. Understanding each Medicare part’s specific coverage is important for beneficiaries, especially for prescription drugs, which can be confusing.

Prescription Drug Coverage Under Medicare Part B

Medicare Part B primarily covers medically necessary doctors’ services, outpatient care, durable medical equipment, and some preventive services. While Part B does not broadly cover all prescription drugs, it provides limited coverage for certain medications administered in specific outpatient settings. These include drugs that require professional administration rather than those self-administered at home.

Part B covers medications given in a doctor’s office or hospital outpatient setting, such as infusions or injections. It also covers certain drugs used with durable medical equipment, like nebulizer medications. Additionally, Part B covers some vaccines, including those for influenza, pneumonia, and Hepatitis B for individuals at medium to high risk.

Oral anti-cancer drugs and anti-emetic drugs (for nausea and vomiting) are also covered under Part B, especially when related to chemotherapy. Immunosuppressive drugs for transplant recipients are covered, with extended coverage for kidney transplant patients. This extended coverage, called Medicare Part B Immunosuppressive Drug (Part B-ID), covers FDA-approved immunosuppressants indefinitely.

Prescription Drugs Not Covered by Medicare Part B

Medicare Part B’s coverage for prescription drugs is limited, focusing primarily on medications administered by a healthcare professional in a clinical setting. It does not cover most outpatient prescription drugs that individuals purchase at a pharmacy and administer themselves. This includes common medications such as pills, creams, and inhalers.

The absence of coverage for these self-administered retail prescriptions under Part B means beneficiaries often need alternative coverage options. This gap in the original Medicare program led to the development of a separate part of Medicare dedicated to addressing broader prescription drug needs.

Understanding Medicare Part D

Medicare Part D is a federal program designed to help beneficiaries pay for self-administered outpatient prescription drugs. These plans are offered by private insurance companies. Part D plans provide coverage for a wide range of brand-name and generic prescription drugs, which are listed on a formulary, a plan’s list of covered medications.

Drug tiers within a formulary categorize medications, with lower tiers having lower out-of-pocket costs. Part D plans involve different stages of coverage, including a deductible phase where beneficiaries pay the full cost of prescriptions. After the deductible, the initial coverage phase begins, where the plan helps cover costs, and beneficiaries pay a copayment or coinsurance. This phase continues until combined spending by the beneficiary and the plan reaches an initial coverage limit.

Historically, a “coverage gap” or “donut hole” existed, but recent legislation has largely closed this for beneficiaries, primarily through manufacturer discounts. After exiting the initial coverage phase and potentially the coverage gap, beneficiaries enter catastrophic coverage, where they pay a reduced amount for covered drugs for the remainder of the year. Premiums, deductibles, and cost-sharing amounts can vary significantly between different Part D plans, making plan comparison important.

Enrolling in Medicare Part D

To enroll in a Medicare Part D plan, individuals must have Medicare Part A or Part B and reside within the plan’s service area. The primary enrollment opportunity for Part D is during the Initial Enrollment Period (IEP), a seven-month window around their 65th birthday. Enrolling during this period helps avoid potential late enrollment penalties.

If the IEP is missed, individuals can enroll or make changes to their Part D coverage during the Annual Enrollment Period (AEP), which runs from October 15 to December 7 each year, with coverage effective on January 1 of the following year. Special Enrollment Periods (SEPs) may also be available under specific qualifying life events, such as moving, losing other creditable drug coverage, or qualifying for Extra Help. These SEPs have specific timeframes, generally two months after the qualifying event, to enroll without penalty.

When selecting a plan, beneficiaries are encouraged to use the Medicare Plan Finder tool on Medicare.gov, which allows for comparison of plans based on individual medications, preferred pharmacies, and budget. Enrollment can be completed in several ways:

• Online via Medicare.gov
• Directly through the chosen plan’s website
• By calling the plan directly
• By calling 1-800-MEDICARE

After enrollment, beneficiaries will receive plan materials detailing their coverage and effective dates.
