Covered medications

The formulary below lists prescription drugs that are covered by NaviCare. We generally cover the drugs listed in our formulary as long as the drug is medically necessary and the prescription is filled at a network pharmacy. Some covered prescription drugs have additional requirements and limits such as prior authorization, step therapy, limited access (only available at certain pharmacies) and quantity limits. The formulary is subject to change at any time. For more information on the most recent list of drugs, see our online Part D drug formulary, or call NaviCare Enrollee Services at 1-877-700-6996 (TRS 711), 8 a.m.–8 p.m., Monday–Friday (7 days a week, Oct. 1–March 31). If you'd like a formulary and over-the-counter drug list mailed to you, please complete our online form.

Request an exception to the formulary

You can ask Fallon Health to make an exception to our coverage rules. There are several types of exceptions that you can ask us to make. You can ask us to: 

• Cover your drug even if it's not on our formulary ("formulary exception").
• Waive coverage restrictions or limits on your drug ("utilization restriction exception"). For example, for certain drugs, we may limit the amount of the drug we'll cover. If your drug has a quantity limit, you can ask us to waive the limit and cover more.

Generally, Fallon Health will only approve your request for an exception if the alternative drugs included on the plan’s formulary would not be as effective in treating your condition and/or would cause you to have adverse medical effects (side effects).

You should contact us to ask for an initial coverage decision for a formulary or utilization restriction exception. When you're requesting a formulary or utilization restriction exception, you should submit a statement from your physician supporting your request. Generally, we must make our decision within 72 hours of getting your prescribing physician’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 your prescribing physician’s supporting statement.

Are there any restrictions on prescription drug coverage?

Some covered drugs may have requirements or limits on coverage. These requirements and limits may include:

• Prior Authorization - Part B versus Part D (B/D): This prescription drug has a Part B versus Part D administrative prior authorization requirement. This drug may be covered under Medicare Part B or Part D depending upon the circumstances. Information may need to be submitted describing the use and setting of the drug to make the determination.
• Home Infusion (HI): This prescription drug is covered under our medical benefit. For more information, call us at 1-877-700-6996 (TRS 711), 8 a.m.–8 p.m., Monday–Friday (7 days a week, Oct. 1–March 31).
• Limited Access (LA): This prescription may be available only at certain pharmacies. For more information, call us at 1-877-700-6996 (TRS 711), 8 a.m.–8 p.m., Monday–Friday (7 days a week, Oct. 1–March 31).
• Mail-Order Drug (MO): This prescription drug is available through our mail-order service.
• Non-Extended Day Supply (NEDS): This prescription cannot be filled for more than a 30-day supply.
• Prior Authorization (PA): Fallon Health requires your physician to get prior authorization for certain drugs. This means that you will need to get approval from Fallon Health before you fill your prescriptions. If you don’t get approval, Fallon Health may not cover the drug.
• Prior Authorization for New Starts only (PA NS): Fallon Health requires a prior authorization for certain drugs for new prescriptions only. This means that if you are newly starting on this drug, you need to get approval from Fallon Health before you fill your prescriptions. If you don’t get approval, Fallon Health may not cover the drug. Prior authorization is not required if you have been previously filling this drug with Fallon Health.
• Quantity Limit (QL): For certain drugs, Fallon Health limits the amount of the drug that we will cover. For example, only 4 capsules per each 28-day period.
• Step Therapy (ST): In some cases, Fallon Health 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, your plan may not cover Drug B unless you try Drug A first. If Drug A does not work for you, your plan will then cover Drug B.

You can find out if your drug has any requirements or limits by looking in the “Notes & Restrictions” column of the drug search results. You may ask Fallon Health to make an exception to these restrictions or limits. Click here for information on how to request an exception to the formulary.

All of the drugs in our formularies are available with an extended-day supply except specialty drugs, opioid drugs and certain narcotics, which are prohibited under Massachusetts State Law from being dispensed in quantities greater than a 30-day supply. These drugs are noted on the formulary as "Non-Extended Day Supply (NEDS)."

Part B step therapy

In some cases, Fallon Health requires you to first try certain drugs to treat your medical condition before we'll cover another drug for that condition. For example, if Drug A and Drug B both treat your medical condition, your plan may not cover Drug B unless you try Drug A first. If Drug A doesn't work for you, your plan will then cover Drug B. Step Therapy may be required for the medications listed in the table below. Choose "Medical benefit formulary" from the dropdown above to search for your drug and any restrictions that may apply.
