What Is a Prior Authorization?

Memorial Hermann Advantage requires you or your provider to get prior authorization for certain drugs. This means that you will need to get approval from us before you fill your prescription(s). If you don't get approval, Memorial Hermann Advantage may not cover the drug.

What if My Drug Is Not on the Drug List?

The plan does not cover all prescription drugs. In some cases, Medicare does not allow any Medicare plan to cover certain types of drugs (for more information about this, refer to your Evidence of Coverage, in Chapter 5). In other cases, we have decided not to include a particular drug on the drug list if another comparable drug is available on our Formulary.

Why Do Some Drugs Have Restrictions?

For certain prescription drugs, special rules restrict how and when the plan covers them. A team of doctors and pharmacists developed these requirements to help our members use drugs in the most effective ways. These special rules also help control overall drug costs, which makes your drug coverage more affordable.

In general, our rules encourage you to get a drug that is safe and works for your medical condition. Whenever a safe, lower-cost drug will work medically just as well as a higher-cost drug, the plan’s rules are designed to encourage you and your doctor to use that lower-cost option. We also need to comply with Medicare’s rules and regulations for drug coverage and cost sharing.

Can the Formulary Change?

Generally, if you are taking a drug on our Formulary that was covered at the beginning of the year, we will not discontinue the drug or add new restrictions during the covered year except when a new, less-expensive generic drug becomes available, or if new information about the safety or effectiveness of a drug is released. Most of the changes in drug coverage happen at the beginning of each year (January 1). The Formulary may change during the year for the following reasons:

  • New FDA-approved drugs are added once they become available.
  • A brand-name drug is replaced with an FDA-approved generic drug.
  • A drug changes to a higher or lower cost-sharing tier.
  • Prior authorizations are added or removed for a drug.
  • Utilization management requirements are added or removed for a drug.
  • The FDA recalls a drug or finds it to be ineffective.

These changes to our Formulary are updated monthly. If your drug has these additional restrictions or limits, you can ask Memorial Hermann Advantage to make an exception to our coverage rules.

How Will I Know if a Formulary Change Impacts Me?

If a change impacts your current drug regimen, we will notify you of the Formulary change at least 30 days before the date that the change becomes effective. Your doctor will also be informed about this change, and we can work with you to find another drug for your condition. However, if the Food and Drug Administration (FDA) deems a drug on our Formulary to be unsafe, if the drug's manufacturer removes the drug from the market, or if a new generic drug replaces a brand name drug on the Drug List, we will immediately remove the drug from the Formulary and provide notice to members who take the drug. In nearly all cases, we must get Medicare approval for changes made to the Formulary.
