Coverage Requirements

For certain prescription drugs, we have additional requirements for coverage or limits on our coverage. This ensures that our members safely use their medications.

Types of additional requirements

Prior authorization (prior approval)

Medications that require prior authorization are prescription medications that require your doctor to obtain approval from us in order to be covered. If your doctor doesn't get prior authorization from us before filling your prescription, you may be financially responsible for the full cost of the medication.

Step therapy

Step Therapy allows us to help your doctor provide you with a drug treatment that is safe, effective, and affordable. Before coverage is allowed for certain costly "second-step" medications, you’re required to first try an effective and less expensive "first-step" medication. 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 doesn't work for you, then we'll cover Drug B.

Formulary quantity limit

For certain drugs, our plans limit the amount of the drug that our plans will cover. For example, our plans provide up to 30 tablets per 30 days per prescription of Simvastatin 10 mg tablets. This may be in addition to a standard one-month or three-month supply.

Non-formulary quantity limit

For certain drugs that are not covered on our formulary, our plans may limit the amount of the drug that our plans will cover if a formulary exception request is approved.
