SilverScript’s Medicare
Part D Formulary Exceptions
and Prior Authorizations

What is a Prior Authorization?

For certain prescription drugs, additional coverage or limit requirements may be in place to ensure that our members use these drugs in a safe way, while also helping to control costs for everyone.

We require you to get SilverScript Medicare Part D Formulary Prior Authorization (prior approval) before certain drugs will be covered under the plan. To receive that approval, you and/or your doctor must complete and submit a Prior Authorization (PA) form. (Download a PA form by clicking on the Prior Authorization Form link below.)

Your prescribing doctor will need to tell us the medical reason why the plan should authorize coverage of your prescription drug. Without the necessary information on the Prior Authorization form, we may not approve coverage of the drug.

What is a Step Therapy requirement?

A Step Therapy requirement means you must first try one drug to treat your medical condition before we will cover another drug for that same condition. For example, if Drug A and Drug B both treat your medical condition, we may require your doctor to prescribe Drug A first. If Drug A does not work for you, then we will cover Drug B.

Look up your drugs and find out more

To find out if the prescription medications you take are subject to Prior Authorization or Step Therapy restrictions, type the name of the drug in the “Look-Up” box below. If your prescription does require Prior Authorization or Step Therapy, please download and have your prescribing doctor complete a Coverage Determination Request Form. The completed form may be faxed to us at 1-855-633-7673. You may also submit an electronic request for a Prior Authorization or Appeal (Redetermination) using our Drug Search Tool.

You may also find out if a drug you take is subject to additional requirements or limits by reviewing your SilverScript 2014 formulary. Or inquire by phone by calling SilverScript Customer Care toll-free at 1-866-362-6212, 24 hours a day, 7 days a week. TTY users call 1-866-552-6288.

What is a Quantity Limit?

Certain covered drugs require a Quantity Limit restriction. That means we will only cover the drug up to a designated quantity or amount. If your prescribing doctor feels it is medically necessary to exceed the set limit, he or she must get prior approval before the higher quantity can be covered. Quantity Limits are generally used as a safety precaution to prevent certain prescription drugs from being used excessively.

What are Exceptions?

As a SilverScript member, you have the right to ask us to make an Exception to our plan formulary. Examples of formulary Exception requests include asking us to:

  • Cover your Part D drug even if it is not included on our formulary (Formulary Exception Request).
  • Waive a restriction (such as a Quantity Limit) on our coverage of a drug (Quantity Exception Request).
  • Provide your drug at a lower copayment if there are drugs for your condition at a lower copayment level. For example, if your drug is included in Tier 3, you can ask us to cover it at the Tier 2 cost-sharing amount instead. Note: if we grant your request to cover a drug that is not on our formulary, you may not also request a higher level of coverage for the same drug. Also, you may not ask us to provide a higher level of coverage for any Tier 4 (Specialty Tier) drugs (Tier Exception Request).

How will I know if a Prior Authorization, Quantity Limit or Step Therapy requirement applies to a drug I take?

There are two ways to find out if these restrictions apply to a drug you take:

  • Search for the drug online using the Drug Search Tool. Search results will indicate if any Prior Authorizations, Quantity Limits or Step Therapy requirements apply.
  • If you cannot search online, call Customer Care toll-free at 1-866-235-5660, 24 hours a day, 7 days a week. TTY users call 1-866-236-1069.

How do I request an Exception?

The best way to request a drug formulary Exception is with the help of your prescribing doctor. He or she must provide a written statement that explains the medical reasons for requesting an Exception. Your doctor can submit a statement to us using a Prior Authorization form or the coverage determination request form; however, no specific form is required.

How long before I get an answer to my Exception request?


  • For standard Exception requests, we will let you know of our decision within 72 hours after the Exception request form is submitted to us with your doctor’s supporting statement.
  • You also have the option to request an expedited Exception request if your doctor believes your health could be seriously harmed by waiting up to 72 hours for a decision. If the Prior Authorization request form submitted to us with your doctor’s supporting statement is considered urgent and we agree, we will let you know of our decision no later than 24 hours.

How do I submit exceptions and prior authorization requests to SilverScript?

  • To file a request by phone or to ask for help submitting your request, call Customer Care toll-free at 1-866-235-5660, 24 hours a day, 7 days a week. TTY users call 1-866-236-1069.
  • To fax your written request, use our toll-free fax number: 1-855-633-7673.
  • To submit a standard request in writing, mail to: SilverScript Insurance Company
    Appeals and Coverage Determination
    MC109 P.O. Box 52000
    Phoenix, AZ 85072-2000
  • To submit your request electronically, use the Drug Search Tool.

If we approve your Exception request, our approval is typically valid until the end of the plan year as long as your prescribing doctor continues to prescribe the Part D drug for you and it continues to be safe and effective for treating your condition. If we deny your Exception request, you may ask for a review of our decision (called a Redetermination) by submitting an Appeal.
