How to Check a Medicare Part D Formulary in West Virginia

Two West Virginia residents can take the exact same pill, sign up during the exact same week, and pay wildly different amounts for it. What separates them is the formulary of the plan each of them picked.

A formulary is the list of prescription drugs a Part D plan agrees to pay for, plus the rules attached to each one. Every insurance company writes its own. And in West Virginia, you may have several dozen standalone drug plans and Medicare Advantage drug plans to choose from, each with a different list.

So the single most useful thing you can do before enrolling is check your own medications against the formulary of the specific plan you are considering, in the West Virginia county where you actually live. Here is how to do that, and what to do when a drug you need is missing.

What a formulary is, and what it controls

Medicare sets the floor. Every Part D plan has to cover at least two drugs in each treatment category, and it has to cover nearly everything in six protected classes: antidepressants, antipsychotics, anticonvulsants, immunosuppressants, cancer drugs, and HIV/AIDS drugs.

Above that floor, the insurance company decides. It decides which drugs make the list, which tier each one lands on, and whether you have to jump through a hoop before the pharmacy will fill it. That is why what Part D actually covers depends so heavily on which plan you bought.

Three things on a formulary drive your cost:

• Whether the drug is on the list at all. If it is not, the plan pays $0 and the pharmacy charges you retail.
• What tier it sits on. Tier drives your copay or coinsurance.
• What restrictions apply. Prior authorization, step therapy, and quantity limits can delay a fill by days or weeks.

How drug tiers work

Most plans use 5 tiers. A few add a sixth for cheap maintenance drugs. The lower the number, the less you pay.

Two things surprise people here. First, a deductible usually applies only to the higher tiers, so your generic blood pressure pill may cost $2 in January while your brand-name inhaler costs full retail until the deductible is met. Second, a tier is an assignment the insurer makes, and it can differ plan to plan. The same medication can be Tier 3 on one plan and Tier 4 on another sold by the same company.

Once you clear the deductible you move into the initial coverage phase, and if your drug costs are high enough you land in the phase where the $2,000 out-of-pocket cap takes over and your Part D spending stops for the year.

How to check your drugs before you enroll

Do this before you sign anything. It takes about 15 minutes.

1. Write down every prescription, exactly. Name, dosage in milligrams, and how often you refill. "Metformin" is not enough. Metformin 1000 mg twice daily is.
2. Pick your pharmacy. Plans have preferred and standard pharmacies, and the price gap between them on the same drug can be significant.
3. Run the list through the plan finder at medicare.gov. Enter your zip code, add each drug with its dosage, then add your pharmacy. The tool shows estimated annual cost per plan, not just the premium.
4. Sort by total annual cost, not premium. A $0 premium plan that puts your specialty drug on Tier 5 will cost you more than a $60 plan that puts it on Tier 3.
5. Look for the restriction flags. The plan finder marks drugs that need prior authorization, step therapy, or have quantity limits. Note every flag.
6. Call the plan and confirm. Formulary files posted online sometimes lag. Get the confirmation before your enrollment window closes.

"Not having access to medications, or a preferred pharmacy, is one of the biggest pain points I see with Medicare beneficiaries every year," says Alex Adams, a licensed Medicare agent in Pevely, Missouri. "The quickest and easiest way to do the research on your own is to utilize the tools on medicare.gov by finding the plan you are considering enrolling into, and adding your prescription, dosage, refill frequency and then pharmacy. Not all plans are going to cover a medication the same, so it is important to be accurate."

The county detail matters more than people expect. Part D plan availability and pricing in West Virginia are set at the county level, so a plan your neighbor two counties over raves about may not even be sold where you live. Working through a full plan comparison with your own WV zip code is the only version of this that means anything.

The three restrictions that catch people

A drug can be on the formulary and still not get filled on the first try.

Prior authorization. Your doctor has to submit paperwork justifying the prescription before the plan pays. Standard decisions take up to 72 hours. Expedited ones take 24. Plan for the delay if you are switching plans in January.

Step therapy. The plan wants you to fail on a cheaper drug first.

"This is called step therapy, and it is common with Medicare Part D plans," says Brett Johnson, a licensed Medicare agent in Fresno, California. "It means the plan may require you to try a lower-cost or preferred medication first before it will cover the drug your doctor originally prescribed. That does not necessarily mean you have to accept the alternative. If your doctor believes the prescribed medication is medically necessary, they can request an exception from the plan."

Quantity limits. The plan covers 30 tablets a month, your doctor wrote for 60. Same fix: your doctor requests an exception with a medical reason.

What to do when your drug is not covered

You have four moves, roughly in order of how fast they work.

1. Ask about a therapeutic alternative. Your doctor may be fine with a covered drug in the same class. Fastest path, no paperwork.
2. Request a formulary exception. Your doctor writes a supporting statement saying the covered alternatives would not work for you or would harm you. The plan has 72 hours to decide, or 24 for an expedited request.
3. Appeal a denial. There are 5 levels, starting with redetermination by the plan itself. Most people who go past level one and reach an independent reviewer do better than they expect. The steps are the same ones in the Medicare appeals process.
4. Use your transition supply while you sort it out. New enrollees are entitled to at least a 30-day fill of a drug they were already taking during their first 90 days on a plan. It buys you time to file the exception.

If cost rather than coverage is the problem, check whether you qualify for Extra Help before you start switching plans. It cuts drug costs far more than a plan change usually does.

Formularies change, including mid-year

Plans can move a drug to a higher tier, add prior authorization, or drop it outright during the plan year. It happens most often when a generic becomes available or the FDA flags a safety problem. When it does, the plan owes you written notice, generally 30 to 60 days ahead, or a transition supply.

The bigger change comes every January. Your plan mails an Annual Notice of Change in late September spelling out next year's formulary, tiers, and pharmacy network. Read the drug section. A tier bump on one specialty medication can swing your annual cost by thousands, and the fall enrollment window is your chance to react to it.

If you have moved recently, that matters too. Part D plans are licensed by region, so a move into or out of West Virginia triggers a special enrollment period and, usually, a new plan search. The rules are covered in changing Medicare plans after a move.

A short checklist

• Exact drug names and dosages, written down
• Your pharmacy, checked as preferred or standard
• Estimated annual cost per plan, not the premium
• Every prior authorization, step therapy, and quantity limit flag on your drugs
• Confirmation from the plan itself before you enroll

None of this requires you to do it alone. A licensed agent in West Virginia can run your drug list against every plan sold in your county in a few minutes, and the service costs you nothing. If you would rather have someone check the formulary math for you, ask a WV agent to pull the comparison before enrollment closes.
