I switched to a new Part D plan and now half my meds require prior authorization. Why didn't anyone warn me this could happen?

Question

Yasmery Vargas · Accepted Answer

When transitioning from a prescription drug plan to a different prescription drug plan, It is extremely important to sit down and review the formulary associated with the plan to make sure your medications are covered. It is also a good practice to consult with your doctors on what insurance they take and/or support for ease of transition. Look out for your Explanation of Benefits and Annual Notice of change later in the year. These documents are made to inform you about what you have and what's to be expected and if there are any changes for the new year. While this may not answer, why there was no warning, hopefully this will help avoid this from happening again.

When your Independent Broker strategized your new Part D plan, that should have been part of the discussion. Oh... you didn't use an Independent Broker... that may be part of the problem

Daniel Brechin · Answer

Generally medicines are listed if covered by your plan should be able to look it up or call the company if there are any doubts.

Gregg Matheny · Answer

The answer to your question is unfortunate, Because no one was "obligated" to do so. The insurance carrier of the Part D plan has a set formulary for you or the broker to look at and next to each medication that is covered are a few indicators like QL (quantity limited) or PA (prior authorization), so in their mind they put the info out for you to look at and it was up to you to determine what it means as well as the implications . A good Broker would have checked your medications and let you know that there may be an issue with the PA medications. There is a silver lining to all of this: your prescribing physician should have a dedicated staff member (or themselves) to notify the insurance carrier that these PA medications are medically necessary. If it is to the point where you had to get involved then that means that somewhere in this process between the insurance, provider, and pharmacy someone is holding things up. This issue (if foreseen) could have been brought to the providers attention before the plan start date and have already had PA's ready to go.

so next time you switch part D plans look for PA's and write down that Medication, then let your provider know what plan you're going to be switching to and remember "the fortune is in the follow-up"

Good luck Medicare friends,

Kelsey Hentzen · Answer

It is always good to check your prescriptions to see if any of them require prior authorization. This should have been discussed during open enrollment when you switched Part D. I would contact the company you worked with to ask why this wasn't discussed fully when you were switched.

This information is required to be in the enrollment materials. If you enrolled yourself you're on your own. If you used an agent or a broker they are required to give you this information. This is precisely the reason why you should use a broker who's not affiliated with any carrier and who doesn't cost you anything to use their expert recommendations.

Part D plans tend to change every year. You absolutely must review your Part D plan every Annual Election Period (AEP) which is always October 15 - December 7. After that, no changes can be made until the next AEP. Your Medicare Specialist can help you with reviewing your plan for the coming year. All Part D plans are in effect from January 1 - December 31.

Derek Rogers · Answer

Part D plans are private, and each creates its own unique "formulary" (drug list) and utilization rules. When you switch plans, your new insurer may impose prior authorization (PA) requirements on drugs that were previously covered automatically. These rules manage costs, ensure safety, or verify medical necessity for expensive or specialized medications. You are often entitled to a one-time "transition refill" (typically a 30-day supply) while your doctor works to obtain the necessary authorizations.

Immediate Steps to Take

Request a Transition Fill: Contact your pharmacy or plan immediately and ask for a "transition refill." This provides a temporary supply while your provider navigates the authorization process.
Contact Your Prescriber: Your doctor’s office is responsible for submitting the prior authorization request. Contact them today to provide the plan's specific requirements, which you can find by calling the member services number on your new insurance card.
Ask About "Step Therapy" and Limits: When speaking with your plan, ask if the PA is due to "step therapy" (requiring you to try a cheaper alternative first) or "quantity limits" (caps on dosage or supply). Knowing this helps your doctor submit the correct paperwork the first time.
Appeal if Denied: If a prior authorization request is denied, you have the right to file an appeal. Start with the internal appeal process directly through your plan.

Plans rarely notify members individually about specific changes to how their current medications are covered prior to enrollment, which is why it is essential to review the "Evidence of Coverage" or use the Medicare.gov plan finder tool to check your specific drug list before switching. Keep in mind that authorizations often need to be renewed annually, so diarize this date to avoid future interruptions.

Travis Harmon · Answer

I understand how frustrating that is. Each Part D plan has its own formulary and rules, and sometimes medications require prior authorization, step therapy, or quantity limits depending on the plan. That’s why it’s so important to review your specific prescriptions during enrollment—we’ll go over those details together so there are no surprises in the future.

I can not tell you why someone did not let you know. But you do have the right to contact medicare and let them know and see if you can change your plan under certain situations.

Diana Garner · Answer

Part D plans are offered through private insurance companies and each one creates their own formulary as well as rules which includes which medications require prior authorization.

When you switched plans, the new plan imposed a prior authorization on medications that were covered without question under the old plan.

This change is not unusual and many plans available now require prior authorization on many medications including but not limited to pain medications.

You are entitled to a transition refill (30-day supply) while the plan and doctor work out the authorization.

Timothy Brown · Answer

Sometimes that can be difficult to assess but keep in mind that not all prescriptions are listed in the same tier from plan to plan and some require prior authorization based on that category.

Dana Dane · Answer

Your agent should have shown you the details of your prescription coverage at the time of enrollment, including but not limited to prior authorization, quantity limits and step therapy. Contact your doctor about prior authorization for those particular medications and they will send prior authorization to your prescription company. Please contact your agent for more information.

Hannah Skinner · Answer

If you used an agent to enroll in this new Part D drug plan, they should have informed you of the prior authorization or step therapy associated with any medications you are taking. 

If you enrolled on your own through Medicare.gov or a carrier website then prior authorization or step therapy would have been listed. This would have been your responsibility to read through before enrolling.

Mary Salmon · Answer

It is extremely important to do an annual review of your prescription drug plan with a reputable licensed agent. The agent should be asking for an updated list of all medications and your preferred pharmacy. By checking your medications against the available plans in your area and their formularies, you can choose a plan that best fits your needs and keeps the prescription drug costs to a minimum.

Betty McCarty · Answer

Prior authorization (PA) requirements have become a growing pain point for many Medicare Part D enrollees, especially in 2025. Here’s why this likely caught you off guard:
•	Each Part D plan sets its own rules: Prior authorization isn’t standardized across plans. A drug covered freely under one plan might require PA under another—even if it’s the exact same medication.
•	Cost-control measures: With the new $2,000 out-of-pocket cap and ($2,100 next year) plans are absorbing more drug costs. To manage expenses, they’re tightening PA requirements, especially for higher-tier or specialty drugs.
•	Limited transparency during enrollment: Many plan comparison tools don’t clearly flag which drugs require PA, and agents may not always dig into the fine print unless asked directly.
You have the right to appeal a PA denial. Call the number on your card, and they will help you begin the process of appeal.

Cheryl Lockhart · Answer

Switching to a new Medicare Part D plan can sometimes come with surprise like medications suddenly requiring prior authorization. Each plan has its own formulary (drug list) and coverage rules, which can include prior authorizations, step therapy, or quantity limits. Even if your medications were covered without issue before, a new plan may handle them differently.

Many plan comparisons focus on cost and whether a drug is covered, but not always how it’s covered. That’s why this can catch people off guard.

The good news is there are solutions. Your doctor can usually submit a prior authorization, and in some cases request an exception if the medication is medically necessary. Many plans will also allow a temporary supply while this is being reviewed.

The important thing to remember when reviewing Part D plans is look beyond coverage and cost so you understand any restrictions that may apply so there are fewer surprises later.

Seeing out an independent licensed agent would be you best course of action here. You should always choose to review your drug list with a licensed Insurance agent so that they can insure that your medications are covered on the drug list with the plan you are looking at. A agent would be able to advise you if they are not and if you may have to go through a drug exception. Seeking an agent advice is worth the time and there is no cost to the consumer. They are licensed, trained and deal with these situations day in and day out for clients. Their expertise is invaluable.

Unfortunately, this is something I hear all too often when meeting with new clients. That's why it's so important to review your Medicare plan and prescription drug coverage each year to make sure your medications are still covered, costs remain competitive, and to identify any drugs that may now require a prior authorization. I make it a priority to review my clients' plans annually, and they always hear from me before the Annual Enrollment Period so we can discuss any important changes and make sure their coverage still meets their needs.

Barbara Barnes, CMIP® · Answer

Did you use a licensed Medicare insurance agent to help you make this change? Did you research your plan options on Medcare.gov? In either case, disclosure should have been made of the medications that require pre-authorization. Did you read all of the plan information and disclosures? 

When you switch insurance companies for your Medicare Advantage or Medicare Part D plan, it is important to acknowledge that you are leaving one company where you perhaps had prior-authorizations already in place or where prior-authorizations were not required, to move to a completely different insurance company with entirely different requirements. The new company will have a different medication formulary and may require different prior-authorizations with entirely different requirements for those authorizations. Step therapy May now be required, or they may require you try different medications or procedures before they will authorize what you want. You cannot make these changes lightly if you are in treatment for a chronic condition. This is another reason to use a licensed and experienced Medicare insurance agent to help you with these potentially treatment-delaying decisions. If you’re going to do this on your own, you need to read and understand everything about the new plan before you make any changes because once you are locked-in to a plan, you likely cannot move again until the next enrollment period.

It will depend on how you switched. If you spoke with an agent or broker or the new PDP plan carrier before you switched, they should have went through your medication list with you and verified what tier they are on and if they were going to need prior authorization. If you did it yourself, then you would have had to do the research with the carriers information they provide in the formulary either online, over the phone or by having them mail you the formulary previous to you enrolling.

Yes that’s correct any time when part d plan changed the new one would have different formulary requirements and rules needs to look at your medications how they are covered.

Tonya Mowan · Answer

When you switched to a new Medicare Part D plan, the new plan has different rules for your medications. That’s why some of your drugs now need prior authorization—which means the plan wants your doctor to explain why you need the medication before they’ll pay for it.

No one may have warned you because:

Each plan has its own list of covered drugs and rules, and

These details aren't always clear unless someone checks your exact medications before you switch.

What you can do now:
Ask your doctor to send in the prior authorization.

Call your plan to see if there’s a similar drug that doesn’t need approval.

Next time you switch plans during an enrollment period, have someone review your full medication list first.

Daniel Keane · Answer

Not all plans indicate whether prior authorization is required. You should talk to the Dr prescribing the medication and they may be able to challenge the requirement.

Anthony Scott · Answer

Unfortunately I have to answer this question with a question. How did you switch your part D plan? Did you do it on your own, without checking the formulary and/or EOC for your new plan first, or did you go to a broker who also didn’t do their due diligence on the new plan with regards to your list of prescriptions?

If you did the switch on your own, you are solely responsible for your situation because you failed to do your due diligence.

If you used a broker and they didn’t point this out to you as well as reviewed multiple plans to see which is the best fit for you, or if that plan was the best fit but the broker didn’t inform you of that prior authorizations would be needed then that was not a good broker and the they are the one responsible.

Heather Johnson · Answer

Whomever you spoke with did not do their due diligence. There are certain plans that do require prior authorization but that was the case with your employer plan as well. The authorization requirements do vary plan to plan and when you made the switch, you should have been informed.

Amanda Holder · Answer

That's a great question.  I'm sorry that you weren't informed about how a plan change works for your Part D prescription drug coverage.  

First, your insurance agent should have properly completed a needs assessment, discuss your medications, deductibles (if any), drug tier levels including if there is a need for a prior authorization, cost, and Maximum Out of Pocket for the year.  This important step is key to gaining knowledge about your Part D plan.  

 Secondly, you should have received an enrollment guide for the plan. This document can provide you with additional information about your medications and authorization requirements.  

Finally, you should have received contact information for the insurance carrier. The carrier can provide you additional information and provide you with the Evidence of Coverage. This document is the contract agreement for your plan.  Hopefully, in the future, you'll be equipped to ask better questions upfront BEFORE you change plans again.

That is why I ask up front for a list of all your prescriptions first, before switching anyone. I provide a print out of your prescriptions and explain it to you. Early in my career, I had a young lady on disability that qualified for Medicare and prescription drug plans. She had a liver transplant. I wanted a list of her prescriptions, but she was hesitant to provide them. She said she just wanted the cheapest drug plan and for me to do that one. I insisted on a list of her prescriptions. She gave them. I found that her most expensive prescription, which was her anti-rejection medication was NOT COVERED on our cheapest plan. Obviously, we went with the other plan. But a deadline for OPEN Enrollment was just days away. She would have been stuck with paying out of pocket for that expensive drug all year. Use a knowledgeable agent!!!
