SilverScript Medicare Part D Drug Plans Review

In this Guide...

SilverScript Medicare plans are the most popular Medicare Part D prescription drug plans in the country. Our review details how much SilverScript drug plans cost, how highly they’re rated by Medicare and what you need to do to enroll if you’re eligible.

SilverScript Medicare plans are Medicare Part D prescription drug plans sold by Aetna, a CVS Health company. Roughly 1 in 4 Medicare Part D beneficiaries were enrolled in a 2023 Part D plan from SilverScript.1

SilverScript Medicare Part D plans cover prescription drug costs, which is an area of health care not typically covered by Original Medicare (Part A and Part B).

Medicare drug coverage may be provided as a standalone Part D plan (PDP), or it may be provided as part of a Medicare Advantage plan that includes drug coverage (also called a Medicare Advantage Prescription Drug plan, or MA-PD). 

The SilverScript family includes several distinct plans. 

Aetna Medicare SilverScript Part D (PDP) plans earned an overall 3.5 out of 5 Star Rating from Medicare in 2022.2

SilverScript Medicare Plan Formulary and the Donut Hole Coverage Gap

SilverScript Medicare Part D plans use the Aetna Medicare drug formulary, which is a list of drugs covered by the plan. Drugs are separated into different tiers, with common generic drugs typically being in Tier 1, and more expensive brand name drugs being in Tier 3 or part of a higher specialty drug tier. 

Part D plans require a monthly premium, and higher income earners may be charged a higher premium. This higher monthly rate is called the Income-Related Medicare Adjusted Amount (IRMAA).

Many Part D plans have annual deductibles and copayments. Deductibles are capped at $545 for the year in 2024, and some Part D plans do not contain any deductible at all.  

Your costs in a Medicare Part D plan are staggered into different phases. The deductible phase begins at the start of the plan year and includes all of your covered Medicare drug spending up until your deductible amount. 

The initial coverage phase begins once you have reached your deductible (or begins right away for plans with no deductible). During this phase, you will make copayments for prescription drugs and refills. 

The coverage gap (often called the Medicare donut hole) begins once you and your plan have combined to spend $5,030 on covered drugs in 2024. Your coverage may be limited during the coverage gap, and you may be required to make increased copayments or coinsurance. You won’t be responsible for paying more than 25% of your plan’s cost for brand name and generic drugs while you’re in the donut hole. 

Lastly, catastrophic coverage begins once your total out-of-pocket drug spending reaches $8,000 and you leave the donut hole. Once you reach this phase, your plan will cover approximately 95% of your remaining drugs costs for the rest of the year.

How to Enroll in a SilverScript Medicare Part D Plan

Medicare has some rules about when you may and may not enroll in a Part D plan, and these will also apply to any SilverScript plan. 

There are generally 3 times at which you may enroll in a Medicare Part D plan

  1. Initial Enrollment Period (IEP)
    Your IEP begins three months before your 65th birthday, includes the month of your birthday and continues for three additional months. During this seven-month period, you can sign up for Medicare Part A and/or Part B as well as a Medicare Advantage plan with drug coverage or a standalone Part D plan.

  2. Fall Medicare Open Enrollment Period (also called the Annual Enrollment Period (AEP)
    The fall Medicare Open Enrollment Period lasts from Oct. 15 to Dec. 7 every year. During this period, you can enroll in a Part D plan, or you can switch from one Part D plan to another. You can also enroll in or switch Medicare Advantage plans, or you could drop your Medicare Advantage plan and return to Original Medicare.

  3. Special Enrollment Period (SEP)
    A Medicare Special Enrollment Period can be granted on a case-by-case basis throughout the year to individuals in specific circumstances. Your individual circumstance will affect what you can do during your Special Enrollment Period and how long the period will last.
