If you’ve ever opened a letter from your Medicare drug plan and wondered, “Why did my prescription drug coverage change again?”, you’re not alone.
One of the biggest surprises for Medicare beneficiaries is that Medicare Part D prescription drug plans can change every year. Even if you loved your plan this year, it may not be the best—or even the same—next year.
Understanding why these changes happen can help you avoid higher costs and ensure your medications remain covered.
Why Do Medicare Drug Plans Change Every Year?
Medicare allows private insurance companies to offer Part D prescription drug plans. Each year, these companies review their plans and make changes based on several factors, including:
- Prescription drug costs
- Negotiated prices with pharmacies
- Manufacturer pricing
- Government regulations
- The medications members are using
- Competition from other plans
Because of these factors, insurance companies update their plans annually.
What Can Change?
Even if you stay in the same plan, several important things may change.
Monthly Premium
Your monthly premium may increase or decrease from one year to the next.
Annual Deductible
The amount you pay before your plan begins sharing costs may change.
Drug Formulary
Every Part D plan has a list of covered medications called a formulary. Drugs can:
- Be added
- Be removed
- Move to a different pricing tier
- Require prior authorization
- Require step therapy
- Have quantity limits added
A medication that was inexpensive this year could become much more expensive next year.
Pharmacy Network
Your preferred pharmacy may no longer be considered “preferred,” which could increase your out-of-pocket costs.
Copays and Coinsurance
The amount you pay for each prescription can change, even if you’re taking the exact same medications.
Why This Matters
Many people automatically allow their Medicare drug plan to renew each year.
While that’s certainly allowed, it isn’t always the best financial decision.
A plan that worked perfectly last year may:
- No longer cover one of your medications
- Cost significantly more
- Have higher deductibles
- Increase prescription copays
- Remove your favorite pharmacy from its preferred network
It’s not uncommon for someone to save hundreds—or even thousands—of dollars simply by reviewing their options each year.
The Annual Notice of Change (ANOC)
Every fall, your plan sends you an Annual Notice of Change (ANOC).
This document explains exactly what will change for the upcoming year, including:
- Premiums
- Deductibles
- Drug coverage
- Pharmacy network
- Copays
- Coinsurance
Unfortunately, many people throw this document away without reading it.
Taking just a few minutes to review it can prevent expensive surprises in January.
When Can You Change Your Drug Plan?
Most beneficiaries can change their Medicare drug plan during the Annual Enrollment Period, which runs from October 15 through December 7 each year.
Any changes you make become effective on January 1.
This is the ideal time to compare plans based on your current medications and pharmacy.
How to Choose the Right Drug Plan
When comparing plans, don’t focus only on the monthly premium.
Also consider:
- Whether all of your prescriptions are covered
- Your estimated annual drug costs
- Your preferred pharmacy
- Deductible amount
- Copays and coinsurance
- Mail-order options
- Overall value—not just the lowest premium
The cheapest plan isn’t always the least expensive once you factor in medication costs.
A Minnesota Tip
If you live in Minnesota, your available Medicare Part D plans can vary by county.
That’s why it’s important to compare plans available where you live rather than relying on recommendations from friends or family in another part of the state.
Bottom Line
Your Medicare prescription drug plan is not designed to stay the same forever.
Insurance companies make changes every year, and those changes can affect your medications, your pharmacy, and your costs.
Reviewing your coverage annually helps ensure you’re receiving the best value for your healthcare dollars.
A little time spent comparing plans each fall can lead to significant savings and fewer surprises throughout the coming year.
