Can Medicare Part D deny coverage for a brand-name drug if a generic isn't available?

Question

Brian Moore · Accepted Answer

Medicare Part D can’t deny coverage for a brand-name drug just because a generic isn’t available—plans must cover it if it’s on their formulary and medically necessary, based on your doctor’s prescription, though they might require prior authorization or step therapy to justify it over other options. Upon enrollment, I always encourage my clients to call me if their medication regimen changes during the year so we can verify coverage details with the carrier and avoid surprises. I’ve dealt with this plenty, and as long as the drug’s listed and no generic exists, your plan has to honor it under CMS rules, but check your formulary or call your provider to confirm it’s not excluded or restricted. If it’s off-formulary, you’d need an exception, which can be a hassle but doable with your doctor’s help.

Yes, insurance companies could deny coverage. However, you can request an appeal if the drug is medically necessary. You will need your physician's support and documentation of the need. The insurance company may agree to a designated amount for the drug, but it may not be in the formula or on any tier levels.

They are not allowed to deny you access to a drug just because a generic is not available. But the part D insurance company will have tiers and pricing for all of their covered prescriptions within their formulary.
If the brand name rx you need is not in their formulary then there is a formulary exception process and/or step therapy process you may have comply with.

Marianne Engengro · Answer

The drug in question would need to be listed on the plan's formulary, however if there is a generic they will prescribe that first. If you and your provider feel it is necessary to be on a brand name drug, the provider should submit a prior authorization for that particular drug. The prior authorization is not a guarantee of the brand name drug being approved.

There is a Medicare rule that states (I am paraphrasing this): Should your Part D plan no longer offer a particular drug, they are required to sell you a one-month supply while you search the web (both US & Canadian discount websites) for a supplier who does include that (usually Brand Name drug) in their drug formulary. If you wish email me at [email protected], I'd be glad to send you my "Drug Discount Websites" digital file which I developed for the Medicare classes which I voluntarily have taught for many years at the University of AZ, here in Tucson.

Plans have a Formulary of covered Medications. All plans have to cover several Medications for each therapeutic class but not necessarily the Medication's you take. Make you check the formulary of the plan you intend to enroll in before making that decision!

All Plans are not created equally. Each Plan as a formulary, which is their list of covered drugs. Depending on the drug, and any other drugs you may take, I can advise which Plans will cover your specific set of drugs, and any related copays/deductibles.

Yes, Medicare Part D plans can deny coverage for brand-name drugs even if a generic equivalent isn't available. 
However, they are required to cover prescription drugs in certain protected classes, and there are exceptions and appeals processes.
Plans may have rules about what drugs are covered and how they are covered in different categories, often favoring generics.

Wild Bill Anderson · Answer

The short answer is…yes.
Each drug will land has its own list(called a formulary. Each drug on the list is thrown out not one of 5 or 6 buckets (called tiers). The tier determines what you pay.
But, you and your doctor always have the right to make an appeal as to why you need a drug not on the list.  Usually takes 72 hours for a response with a thumbs up or not.

Karen Ansell · Answer

Yes, a Medicare part D plan can deny coverage for a brand if a generic is not available.
All plans have formularies which is a list of medications that they cover. Even though that specific medications might not be covered they must have meds that are covered for all illnesses.

Lesley Burns · Answer

Yes, Medicare Part D plans can deny coverage for brand-name prescriptions even if a generic isn't available. The plan's formulary may only cover the generic.

Andrew Kramer · Answer

That depends. If there is a similar generic medication for that illness, then Medicare can require "step-therapy" meaning the patient will need to try the generic to see if it works. If it does not work, or the patient exhibits a drug side effect to the generic, then the Dr can seek an authorization for the brand name. But if there are no other generic medications for that illness, then Medicare cannot deny the brand name.
