Your Medicare Advantage Plan Might Not Cover as Much as You Think
Medicare Advantage plans can seem like a great alternative to Original Medicare, offering extra benefits and sometimes lower premiums. But as you dig deeper, you may find that these plans don’t always cover as much as you expect. From strict provider networks to out-of-pocket costs, it’s important to know what you’re signing up for.
Let’s break down four key reasons why your Medicare Advantage plan might not provide the coverage you assumed—and what you can do to avoid unexpected expenses.
1. Limited Provider Networks Can Restrict Your Choices
Unlike Original Medicare, which allows you to visit any doctor or hospital that accepts Medicare, Medicare Advantage plans typically operate within a defined network of providers. If you see a doctor outside of your plan’s network, you may face higher costs or even have to pay the full bill yourself.
What This Means for You
-
You must check if your preferred doctors and hospitals are in-network. Otherwise, switching plans or finding new providers may be necessary.
-
Emergency and urgent care are usually covered, but non-emergency visits outside your network may result in higher costs.
-
Provider networks change annually, meaning the doctor you see today may not be covered next year.
-
Specialists may have even stricter network restrictions, requiring you to obtain referrals or switch to in-network alternatives.
-
Hospitals and healthcare systems can drop out of networks mid-year, leaving you scrambling to find new options.
What You Can Do About It
-
Before enrolling, review your plan’s provider directory to confirm coverage for your doctors.
-
During Medicare’s Open Enrollment Period (October 15 – December 7), check for changes in provider networks.
-
If you frequently travel or live in multiple states, consider options that provide more nationwide access.
-
Ask your doctor if they anticipate remaining in-network for the upcoming year to avoid disruptions.
2. Higher Out-of-Pocket Costs Can Add Up Quickly
Medicare Advantage plans may have lower monthly premiums than Original Medicare plus a Medigap plan, but they often come with more out-of-pocket expenses. These costs can include deductibles, copayments, and coinsurance, which vary depending on your plan.
What This Means for You
-
Annual out-of-pocket maximums apply, but they can be high. Once you hit the maximum, your plan covers 100% of covered services.
-
Certain services may have high copayments, especially for specialists or hospital stays.
-
Prescription drug coverage varies, and you could end up paying more for your medications depending on your plan’s formulary.
-
Out-of-pocket costs can change from year to year, requiring you to reevaluate your budget.
-
Some plans may require separate copayments for different services during a single visit, leading to higher expenses.
What You Can Do About It
-
Compare out-of-pocket costs before selecting a plan to avoid unexpected expenses.
-
Review the plan’s Summary of Benefits to see how much you’ll pay for common healthcare services.
-
Consider whether enrolling in a supplemental plan could help offset high medical costs.
-
Ask your provider about potential hidden costs before undergoing treatment.
3. Prior Authorization and Coverage Restrictions Can Delay Care
Medicare Advantage plans often require prior authorization for certain services, meaning you must get approval before receiving treatment. This can delay care and even result in denied claims if your request is not approved.
What This Means for You
-
Some treatments, procedures, and medications require pre-approval, which can take time.
-
Failure to get prior authorization could result in denied claims, leaving you responsible for the full cost.
-
Certain medications may have step therapy requirements, meaning you must try a lower-cost alternative before your plan covers a more expensive prescription.
-
Pre-approval rules may change yearly, making it harder to predict your coverage needs.
-
Some necessary treatments might be denied or require appeals, leading to delays in receiving critical care.
What You Can Do About It
-
Ask your doctor about prior authorization requirements before scheduling procedures.
-
If your request is denied, file an appeal or work with your doctor to provide additional documentation.
-
Review your plan’s drug formulary to check for coverage restrictions on your medications.
-
Keep records of past authorizations in case your plan changes its policies.
4. Coverage for Extra Benefits Isn’t Always Guaranteed
Medicare Advantage plans often advertise additional benefits, such as dental, vision, hearing, and wellness programs. However, these benefits vary widely by plan and may have coverage limits or restrictions.
What This Means for You
-
Dental, vision, and hearing benefits are not included in all plans, and coverage may be limited to certain procedures or exams.
-
Over-the-counter allowances and transportation benefits vary, and some plans may require you to use specific providers.
-
Supplemental benefits are not guaranteed from year to year, meaning they could change or be removed entirely.
-
Coverage limits may include caps on the number of covered visits or treatments per year.
-
Certain benefits might only be available in specific regions, restricting access based on where you live.
What You Can Do About It
-
Read the plan’s Evidence of Coverage to understand exactly what is included.
-
If you need dental, vision, or hearing coverage, consider separate insurance plans that provide more comprehensive benefits.
-
Check for updates each year, as plan benefits can change during the Annual Enrollment Period.
-
Budget for potential out-of-pocket costs if your plan reduces or removes a supplemental benefit.
Understanding Your Medicare Options to Avoid Unwanted Surprises
While Medicare Advantage plans can offer valuable benefits, they may not cover as much as you expect. To avoid unexpected costs and restrictions:
-

Compare different Medicare options each year to ensure your plan still meets your needs.
-
Monitor annual changes to provider networks, costs, and benefits so you can make informed decisions.
