Will my Medicare Part D plan cover my HIV medications, and can the plan drop them from its formulary?
Answered by 8 licensed agents
Part D medications: these are medications covered on your plan's formulary. They are medications that you pick up at the pharmacy or have shipped to you at home. Commonly, these are tablets or capsules which treat HIV.
Part B medications: these are medications received in a medical office or facility and administered by a healthcare professional. These are billed differently than medications covered by Part D. Rather than a co-pay, you will be responsible for the 20% coinsurance that Medicare does not pay. If you have Traditional Medicare with a Standalone Prescription Drug Plan, you will pay 20% of the Medicare contracted rate. If you have a Medicare Advantage plan, you will pay 20% as well. If you have a Medicare supplement plan, and depending on what plan you have, such as a Plan G, a Plan F or a Plan N, your insurance company will cover the 20%. If you have a High Deductible Plan, such as HDP G or F, you will have 20% cost share until you reach your deductible. Typically preventative medications, such as PrEP, would be a Part B medication.
As for whether the plan will drop a drug from its formulary, that is something you will need to review on a yearly basis. Formularies are locked in for the year. During Annual Enrollment Period you need to review your drug plan or Medicare Advantage plan in order to ensure your prescriptions are covered on your plan for the following year. Historically, formularies do not drop coverage for a drug during the plan year.

Plans review and update their formularies annually. While they must still abide by the "substantially all" rule for HIV drugs, they may shift a drug to a different cost tier (changing your copay/coinsurance) or swap equivalent treatments for the upcoming year.
Your plan is required to send you an Annual Notice of Change (ANOC) every fall detailing any tier shifts or cost changes taking effect on January 1.

Your plan cannot simply drop your medication to save money. Limited changes are allowed, such as when a drug becomes unsafe, leaves the market, or is replaced with a generic under Medicare’s rules.
Always check your specific medications and costs before choosing a plan. If you receive a notice about a coverage change, contact your plan and HIV care provider right away to help keep your treatment on track.

However, plans can make certain formulary changes, so it's important to review your coverage each year. If a medication is affected, you may have options such as exceptions, appeals, and temporary transition supplies.
My advice: Never assume your medication will automatically remain covered. Check your plan before making a change, and never stop treatment without talking to your doctor.
