Prior Authorization is a program that requires members to meet certain criteria prior to a drug being covered. It may be used to encourage the appropriate use of prescribed drugs based on the U.S. Food and Drug Administration (FDA) approved labeling and other medical literature.

Quantity limits are restrictions our plan puts on the amount of drug we will cover per prescription. These limits are designed to identify the excessive use of drugs which may be harmful in large quantities, to highlight the potential need for a different type of treatment, and to match dosing recommendations / requirements set by the manufacturer and the FDA.

Our Medicare prescription drug coverage has rules to ensure the quality of members' care.

• Certain drugs have quantity limits.
• Certain drugs require prior authorization.
• Certain drugs require step therapy.
• Compounded medications require an exception request to be approved.
• Drug benefits or services not described in the plan formulary or the Evidence of Coverage, or not required by law or regulations, are not covered.
• Drugs covered by Medicare Part B are not payable as Part D benefits. (Refer to your Medicare Part B coverage documents for Part B drug coverage.)
• If a Medicare beneficiary is eligible for Part D and does not sign up in the initial enrollment period, a Medicare late enrollment penalty may apply.
• Generally, coverage is not available to refill medications before 75% of the medication on-hand has been used. For example, if the prescription is written for a 30-day supply, you may refill once there is 7 or less days supply of the medication on-hand.
• Members must use network pharmacies to receive full benefits.
• Plan benefits and premium are subject to change annually.
• Prescriptions filled by pharmacies outside the United States or its territories, even for a medical emergency, are not covered.
• Prescriptions filled prior to effective date of coverage or after disenrollment date are not covered.
• Replacement of lost or stolen prescriptions are not covered.
• The plan's contract may be canceled by either the plan or the Centers for Medicare & Medicaid Services.
• All claims must be received within 3 years of the fill date. For example, if a drug is purchased on January 31, 2026, the claim must be received no later than January 31, 2029. Claims received after this time frame will not be eligible for coverage.
