Choosing Medicare coverage can feel overwhelming when you first start looking at your options. You may find several plans with different costs, provider networks, drug coverage, and benefits. Knowing what to compare can make the process easier.

If you live in the St. Louis area, medicare advantage st louis options can vary based on where you live and the plans available in your service area. Your doctor, prescriptions, budget, and healthcare needs should all factor into your decision.

Before you enroll, take some time to compare the details instead of choosing a plan based on one feature. Here are six things you should check.

A Guide to Comparing Medicare Advantage Plans in St. Louis

1. Start With Your Doctors and Hospitals

Your doctors and hospitals should be among the first things you check. List your primary doctor, specialists, and preferred hospitals, then confirm they are in each plan’s network. 

Medicare Advantage plans have different networks and may have rules for out-of-network care. Don’t assume a doctor who accepts Medicare is part of every Medicare Advantage plan. Always check the specific plan before enrolling. 

2. Review Your Prescription Drugs

Your prescriptions can affect the plan you choose.

Start by writing down all the medicines you take. Include the name, dosage, and how often you take each one. Then check the plan's drug coverage to see whether it includes your prescriptions.

You should also look at the pharmacies that work with the plan. If you already use a pharmacy you like, check whether it is included.

Don't just ask whether your medicine is covered. Look at the cost you may have to pay and any rules that apply to getting the prescription.

Medicare's plan comparison tool lets you enter your drugs and pharmacies to compare plan information and estimated costs.

3. Compare the Full Cost of Each Plan

The monthly premium is only part of your healthcare costs. When comparing plans, check:

  • Premium and deductible

  • Doctor and specialist copays

  • Hospital and prescription costs

  • Out-of-pocket limit

  • Out-of-network costs, if applicable

A low premium does not always mean lower overall costs. To estimate your yearly expenses, consider how often you see a doctor, take prescriptions, or need specialist care.

4. Check the Extra Benefits and Their Limits

Some Medicare Advantage plans offer benefits beyond what Original Medicare covers. Depending on the plan, these may include dental, vision, hearing, fitness, or other services. The benefits and limits can vary by plan and location.

Look at the details instead of choosing a plan based on one extra benefit.

For example, if dental coverage matters to you, check what services are covered, whether there are limits, and which dentists you can use. Do the same for vision and hearing benefits.

An extra benefit may sound useful, but it may not help much if it doesn't match your needs or comes with rules you didn't expect.

5. Understand the Plan Type and Its Rules

Medicare Advantage plans can work in different ways. Common types include HMOs, PPOs, PFFS plans, and Special Needs Plans. Each type can have different rules for providers, referrals, and out-of-network care.

Before choosing a plan, ask yourself:

  1. Do I need to choose a primary care doctor?

  2. Do I need a referral to see a specialist?

  3. Can I visit an out-of-network provider?

  4. What will I pay if I use an out-of-network provider?

  5. Are certain services subject to prior authorization?

These questions can help you understand how the plan works when you actually need care.

6. Check the Plan Before You Enroll

Once you narrow down your options, review the plan’s doctors, hospitals, prescriptions, costs, benefits, and network rules. Make sure it is available in your area and that you understand the enrollment requirements.

If you already have Medicare Advantage, review your plan each year, as costs, benefits, and networks can change. The Annual Open Enrollment Period runs from October 15 to December 7, while other enrollment periods may apply based on your situation.

Summary

Choosing a Medicare Advantage plan is about more than finding a low monthly premium. Consider your doctors, prescriptions, healthcare costs, network, benefits, and the rules that come with the plan.

Take your time and compare the details before you enroll. If you live in the St. Louis Metro and want help understanding your choices, Show Me 65 can help you review Medicare Advantage options and compare them based on your needs.
