SilverScript Medicare Part D Drug Plans Review
The SilverScript Choice Medicare plan is one of the most popular Medicare Part D prescription drug plans in the country. Our review details SilverScript Choice drug plan premiums, copays, deductibles and more.
SilverScript Medicare plans are Medicare Part D prescription drug plans sold by Aetna, a CVS Health company. Roughly 1 in 5 Medicare Part D beneficiaries are enrolled in a 2025 Part D plan from SilverScript.
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.
SilverScript Choice (PDP)
In 2025, the SilverScript Choice plan offers average premiums of $45 per month and copayments of $5 or less for Tier 1 medications at network pharmacies.
The SilverScript Choice plan accounted for the second-highest share of 2025 enrollment among Part D plans offered nationwide. Nearly 3.5 million Part D beneficiaries in the country are enrolled in the SilverScript Choice plan for 2025.
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 $590 for the year in 2025, 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.
2025 Medicare Part D coverage includes an annual $2,000 out-of-pocket spending limit for what you'll pay for prescription drugs that are covered by your plan. After you spend this amount on covered drugs, you won't pay any additional copays for your covered drugs for the remainder of the year.
SilverScript Medicare Part D plans must be used within a network of participating pharmacies. Because SilverScript is part of the CVS family, these plans may be used at thousands of CVS locations all over the U.S., in addition to other participating pharmacy chains.
You can search for pharmacies near you that accept SilverScript Part D plans from Aetna.
CVS Specialty Pharmacy
SilverScript Part D plans may be used with the CVS Specialty Pharmacy. This online pharmacy focuses on medications that might not typically available at brick-and-mortar retail pharmacies.
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.
- 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. - 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. - 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.
