What is the Prevea360 Medicare Advantage Formulary?

  • A formulary is a list of covered drugs created in consultation with a team of healthcare providers, which represents the prescription therapies believed to be a necessary part of a quality treatment program.
  • The covered drugs are listed on the formulary as long as the medication is medically necessary, the prescription is filled at an in-network pharmacy, and other plan rules are followed. Please review your Evidence of Coverage for more detailed information about your formulary and how to fill your prescriptions.
  • If a drug is not listed in your drug formulary, the product is not covered under your pharmacy benefit. If you decide to fill a prescription for a product not on the formulary, you are responsible for 100% of the cost. The cost is also not counted toward deductibles or out-of-pocket maximums.

Ways to save on your prescriptions:

Generic drugs

  • Generic drugs usually cost less than brand-name drugs. They are rated by the Food and Drug Administration (FDA) to be as safe and effective as brand-name drugs.

Fill prescriptions for 100-days instead of 90-days

  • Save 1 extra fill a year by requesting your doctor write a 100-day supply for all the maintenance medications you take. 
  • $0 for a 100-day fill at a mail-order pharmacy for Tier 1 and Tier 2 drugs at Costco retail and mail-order pharmacies – no Costco membership required.

Use our preferred retail pharmacy network or mail order pharmacy 

  • Members save money by filling prescriptions in our preferred retail pharmacy network and through our mail order pharmacy.
  • Preferred pharmacies include all SSM pharmacies, Walgreens, Walmart, Costco, and Forward Pharmacy.

Vaccine savings

  • $0 vaccine at the doctor's office or the pharmacy. Vaccines typically given at your pharmacy can now be offered when you see your doctor.

Insulin savings

  • You will pay a $30 copay per prescription at a preferred pharmacy or a $35 one at a standard pharmacy. These savings apply through the deductible and copay stages and the donut hole.

If you have a question about covered drugs or would like a formulary mailed to you, call our Customer Care Center at (877) 232-7566 (TTY: 711).

Generally, if you are taking a drug on our current year formulary that was covered at the beginning of the year, we will not discontinue or reduce coverage of the drug during the coverage year except when a new, less expensive generic drug becomes available or when new adverse information about the safety or effectiveness of a drug is released. Other types of formulary changes, such as removing a drug from our formulary, will not affect members who are currently taking the drug. It will remain available at the same cost sharing for those members taking it for the remainder of the coverage year. We feel it is important that you have continued access for the remainder of the coverage year to the formulary drugs that were available when you chose our plan, except for cases in which you can save additional money or we can ensure your safety.

If we remove drugs from our formulary, or add prior authorization, quantity limits and/or step therapy restrictions on a drug or move a drug to a higher cost-sharing tier, we must notify affected members of the change at least 60 days before the change becomes effective, or at the time the member requests a refill of the drug, at which time the member will receive a 60-day supply of the drug. If a new generic becomes available in place of a brand name, you will get a 30-day notice about the change.

If the Food and Drug Administration deems a drug on our formulary to be unsafe or the drug’s manufacturer removes the drug from the market, we will immediately remove the drug from our formulary and provide notice to members who take the drug.

Some covered drugs may have additional requirements or limits on coverage. These requirements and limits may include:
Prior Authorization (PA): Prevea360 Medicare Advantage requires you (or your physician) to get prior authorization for certain drugs. This means that you will need to get approval from Prevea360 Medicare Advantage before you fill your prescriptions. If you don’t get approval, Prevea360 Medicare Advantage may not cover the drug.

Prior Authorization Restriction for Part B vs Part D Determination (PA BvD): This drug may be eligible for payment under Medicare Part B or Part D. You (or your physician) are required to get prior authorization from Prevea360 Medicare Advantage to determine that this drug is covered under Medicare Part D before you fill your prescription for this drug. Without prior approval, Prevea360 Medicare Advantage may not cover this drug.

Prior Authorization Restriction for New Starts Only (PA NSO): If you are a new member, you (or your physician) are required to get prior authorization from Prevea360 Medicare Advantage before you fill your prescription for this drug. Without prior approval, Prevea360 Medicare Advantage may not cover this drug.

Quantity Limits (QL): For certain drugs, Prevea360 Advantage limits the amount of the drug that Dean Advantage will cover. For example, Prevea360 Advantage provides nine tabs per prescription for sumatriptan tab.

Step Therapy (ST): In some cases, Prevea360 Advantage requires you to first try certain drugs to treat your medical condition before we will cover another drug for that condition. For example, if Drug A and Drug B both treat your medical condition, Prevea360 Advantage may not cover Drug B unless you try Drug A first. If Drug A does not work for you, Prevea360 Advantage will then cover Drug B

Non-Mail-Order Drug (NM): You may be able to receive greater than a one-month supply of most of the drugs on your Formulary via mail order at a reduced cost share. Drugs not available via your mail-order benefit are noted with “NM” in the notes column of your Formulary.

Limited Distribution (LD): The symbol (LD) next to a drug name indicates that the drug has been noted as being restricted to certain pharmacies by the Food and Drug Administration. These drugs can only be obtained at specialty designated pharmacies able to appropriately handle the drugs.

If your drug is not included in the formulary, you should first contact Member Services and ask if your drug is covered. If you learn that Prevea360 Medicare Advantage does not cover your drug, you have two options:

You can ask Member Services for a list of similar drugs that are covered by Prevea360 Medicare Advantage. When you receive the list, show it to your doctor and ask him or her to prescribe a similar drug that is covered by Prevea360 Medicare Advantage.

You can ask Prevea360 Medicare Advantage to make an exception and cover your drug. See below for information about how to request an exception.

Prevea360 Medicare Advantage will only approve your request for an exception if the alternative drugs included on the plan’s formulary, or additional utilization restrictions would not be as effective in treating your condition and/or would cause you to have adverse medical effects.

When you request a formulary or utilization restriction exception you should submit a statement from your prescriber or physician supporting your request.

Generally, we must make our decision within 72 hours of getting your prescriber’s supporting statement. You can request an expedited (fast) exception if you or your doctor believe that your health could be seriously harmed by waiting up to 72 hours for a decision. If your request to expedite is granted, we must give you a decision no later than 24 hours after we get a supporting statement from your doctor or other prescriber.

You can ask Prevea360 Medicare Advantage to make an exception to our coverage rules. Please visit the Part D Drug Coverage Determination, Exceptions, Appeals and Grievance page for more information. There are several types of exceptions that you can ask us to make:

  • You can ask us to cover a drug even if it is not on our formulary. If approved, this drug will be covered at a pre-determined cost-sharing level, and you would not be able to ask us to provide the drug at a lower cost-sharing level.

  • You can ask us to cover a formulary drug at a lower cost-sharing level (if this drug is not on the specialty tier). If approved this would lower the amount you must pay for your drug.

  • You can ask us to waive coverage restrictions or limits on your drug. For example, for certain drugs, we limit the amount of the drug that we will cover. If your drug has a quantity limit, you can ask us to waive the limit and cover a greater amount..

You should contact us to ask for an initial coverage decision for a formulary or utilization restriction exception.

Please review the Pharmacy Transition Process page to learn more about exceptions when you are a new member or other special situation.

As a new or continuing member in our plan, you may be taking drugs that are not on our formulary. Or, you may be taking a drug that is on our formulary but your ability to get it is limited. For example, you may need a prior authorization from us before you can fill your prescription.

You should talk to your doctor to decide if you should switch to a drug on the formulary that we cover or request a formulary exception so that we will cover the drug you take. While you talk to your doctor to determine the right course of action for you, we may cover your drug in certain cases during the first 90 days you are a new member on.
