Part D

Medicare Part D

What is Medicare Part D ?


Medicare Part D is a prescription drug coverage program offered by the federal government to Medicare beneficiaries. It was introduced in 2006 as a result of the Medicare Prescription Drug, Improvement, and Modernization Act.


What is the Part D formulary ?


Medicare Part D formulary is a list of prescription drugs covered by a specific Medicare Part D prescription drug plan (PDP) or a Medicare Advantage prescription drug plan (MAPD). Each formulary is developed and maintained by private insurance companies that offer these Part D plans, and they are approved by Medicare.

Here are some key points about Medicare Part D formularies:


Drug Coverage: Formularies include a wide range of prescription drugs, including brand-name drugs and generic drugs. The list is designed to meet the needs of beneficiaries and provide coverage for essential medications.


Tiers and Cost-Sharing: Formularies often organize drugs into different tiers, with each tier having a different cost-sharing amount (e.g., copayment or coinsurance) associated with it. Typically, generic drugs are placed in lower tiers and have lower costs, while brand-name drugs are placed in higher tiers with higher costs.


Changes and Updates: Medicare Part D formularies can change from year to year, so it's important for beneficiaries to review their plan's formulary annually during the Medicare Annual Enrollment Period (AEP). During this time, beneficiaries can switch to a different Part D plan if their current plan's formulary no longer covers their medications.


Prior Authorization and Step Therapy: Some medications on the formulary may require prior authorization from the plan before they are covered. Additionally, some plans may implement step therapy, which means beneficiaries must try certain lower-cost drugs before the plan covers a higher-cost drug for a specific condition.


Exceptions and Appeals: If a drug is not on the formulary or is subject to certain restrictions, beneficiaries and their healthcare providers can request exceptions or file an appeal to get coverage for the medication if they believe it is medically necessary.


Medicare Part D late Enrollment penalty (LEP)



Medicare Part D provides prescription drug coverage for people with Medicare. It's important to enroll in a Part D plan when you're first eligible because if you go 63 days or more in a row without Medicare prescription drug coverage, you might owe a late enrollment penalty if you join a plan later.


The Part D late enrollment penalty is an amount that's added to your Part D premium. The cost of the penalty depends on how long you went without Part D or creditable prescription drug coverage.

Here's how the penalty is calculated:


Medicare calculates the penalty by multiplying 1% of the "national base beneficiary premium" by the number of full, uncovered months you were eligible but didn't join a Medicare drug plan and went without other creditable prescription drug coverage.


The national base beneficiary premium may change each year, so the penalty amount can also change each year.


You may have to pay this penalty for as long as you have Medicare prescription drug coverage.


Extra Help also called (LIS): Medicare Extra Help is a program designed to aid eligible low-income individuals in reducing their out-of-pocket costs for prescription medications, significantly easing their financial burdens related to healthcare. This can also help them pay for the entire premium of the Prescription Drug Plan, or a portion of it depending on the level of LIS assigned.


Pharmaceutical Aid to The Aged And Disabled (PAAD): The State Pharmaceutical Assistance Program (PAAD), is a state-funded initiative providing financial assistance for prescription medications to eligible senior citizens and disabled individuals. Also it helps lower the premium of the Prescription Drug Plan if any, or in some cases can cover the entire premium.


You'll be notified by your plan if you owe a penalty. The notice will tell you how much the penalty is and whether it's included in your premium bill or if you'll get a separate bill for it.


Different stages of the Part D


Medicare Part D is a prescription drug coverage program offered by the U.S. government for Medicare beneficiaries. The program is designed to help individuals with their prescription drug costs. Medicare Part D consists of different stages that determine how much beneficiaries pay for their medications throughout the year. The stages were as follows:


Deductible Stage: At the beginning of each year, beneficiaries enter the Initial Deductible Stage. During this stage, you will be responsible for paying the full cost of your prescription drugs until you reach the annual deductible amount set by Medicare. Once you meet the deductible, you move on to the next stage.


Initial Coverage Stage: After meeting your deductible, you enter the Initial Coverage Stage. During this stage, Medicare will cover a portion of your prescription drug costs, and you will be responsible for paying a copayment or coinsurance for each medication you receive. The insurance company will also pay its share of the cost.


Coverage Gap (Donut Hole): In the past, after reaching a certain spending limit in the Initial Coverage Stage, beneficiaries entered the Coverage Gap or Donut Hole. During this stage, you were required to pay a higher percentage of the drug costs until you reached the out-of-pocket threshold. However, since the introduction of the Affordable Care Act (ACA), the coverage gap has been gradually closing, and the out-of-pocket costs for beneficiaries have decreased.


Catastrophic Coverage Stage: Once you have spent a certain amount of money out-of-pocket on prescription drugs (including both your share and the drug manufacturer's discount), you enter the Catastrophic Coverage Stage. During this stage, you pay a reduced amount or coinsurance for your medications for the rest of the calendar year. This stage provides financial relief for beneficiaries with high drug expenses.




Part D formulary tiers



Medicare Part D formulary tiers are used by prescription drug plans to categorize and price medications. Each plan has its own formulary, which is a list of covered drugs, organized into different tiers based on their cost and medical necessity. The formulary tiers help determine how much you will pay out-of-pocket for your prescription medications. The following are the typical formulary tiers used in Medicare Part D plans:

Tier 1 - Preferred Generic Drugs: This tier includes the most affordable prescription drugs, mainly generic medications that have been proven to be safe and effective. These drugs tend to have the lowest copayment or coinsurance amounts, making them the most cost-effective option for beneficiaries.

Tier 2 - Generic Drugs: The second tier consists of other generic medications that may have a slightly higher cost than those in Tier 1. However, they are still more affordable than brand-name drugs. The copayments or coinsurance for Tier 2 drugs are higher than those in Tier 1 but lower than the subsequent tiers.

Tier 3 - Preferred Brand-Name Drugs: This tier includes brand-name medications that are preferred by the plan. These drugs might have a lower cost or offer some therapeutic advantages over other brand-name alternatives. The copayments or coinsurance for Tier 3 drugs are higher than those in Tiers 1 and 2 but lower than Tier 4.

Tier 4 - Non-Preferred Brand-Name Drugs: Non-preferred brand-name drugs are generally more expensive than preferred brand-name drugs. These medications may have alternatives available in lower tiers that offer similar therapeutic benefits at a lower cost. Copayments or coinsurance for Tier 4 drugs are higher compared to the previous tiers.

Tier 5 - Specialty Drugs: This tier includes high-cost specialty medications used to treat complex or chronic conditions such as certain types of cancer, autoimmune disorders, or rare diseases. Specialty drugs often require special handling, administration, or monitoring. Consequently, they come with the highest copayments or coinsurance amounts.


It's essential to review your specific Medicare Part D plan's formulary to understand which drugs are covered and which tier they fall into. Some plans may have additional tiers, offer coverage in the coverage gap (donut hole) for certain medications, or provide extra financial assistance for low-income individuals.


If your healthcare provider prescribes a medication that falls into a higher tier, you may want to discuss alternative medications that are in a lower tier to help reduce your out-of-pocket costs. You can also work with your healthcare provider and the Medicare Part D plan to request an exception if you believe a lower-tier drug would be more appropriate for your medical needs.
