Medicare Plans

Medicare Advantage (Part C) in St. Louis, MO

With a Medicare Advantage plan, a private company approved by Medicare pays your claims in place of Original Medicare. You're still on Medicare. The plan just runs your hospital, doctor and usually your drug coverage under a single card.

You get a lower premium in exchange for copays and a network. In St. Louis, the network is the whole question. The metro has BJC, Mercy, SSM Health and St. Luke's, and a plan that works for a Mercy patient in Creve Coeur may not work for someone who sees doctors at Barnes-Jewish.

  • Lower or $0 monthly plan premium
  • Yearly cap on your out-of-pocket costs
  • Drug coverage usually built in
  • Extras like dental, vision and hearing

Look at the network before the premium

Not every plan contracts with every St. Louis hospital system, and contracts can change at renewal. We check your doctors, your hospital and your pharmacy against this year's directory before you sign anything.

Costs

What you pay with a Part C plan

Your Part B premium still goes to Medicare. For most people that's $202.90 a month in 2026. The Advantage plan may add its own premium, from $0 to a modest amount, and then you pay copays as you use care: a set amount to see your family doctor, a higher one for a specialist, and more for outpatient surgery or a hospital stay.

The safety net is the yearly out-of-pocket maximum. Once you reach it, the plan pays for covered in-network care for the rest of the year. Original Medicare by itself has no cap like that, which is why people who don't buy a Medigap plan often go with Advantage. To weigh the two, read Advantage vs. Medigap in St. Louis.

  • Your monthly Part B premium doesn't go away
  • Flat copays take the place of most coinsurance
  • The out-of-pocket maximum caps a rough year
  • Networks, benefits and drug lists can change every January 1

Extras

Sizing up the extra benefits

  • Dental, vision and hearing

    These allowances differ a lot. A large dollar figure in an ad may only apply to certain services, so ask what a cleaning and a crown are each worth.
  • Drug coverage included

    Most Advantage plans include Part D. Run your exact prescriptions through the plan's drug list, since the tier a drug lands on matters more than the premium. See Part D drug plans.
  • Fitness, rides and OTC cards

    Gym memberships, over-the-counter allowances and rides to appointments are common. They help if you'll really use them.

Timing

When you can join or switch

Most people sign up during their Initial Enrollment Period when they're turning 65, or during the Annual Open Enrollment Period from October 15 to December 7. If you're already in an Advantage plan, the Medicare Advantage Open Enrollment Period from January 1 to March 31 gives you one more change.

A move, the end of employer coverage or qualifying for Extra Help can open a Special Enrollment Period at other times of year. Already in a plan you don't like? Start with switching your plan.

Prior authorization

The approval step you don't have with Original Medicare

Many Advantage plans want to approve higher-cost care before they pay for it. That often includes MRI and CT scans, outpatient surgery, a skilled nursing stay after the hospital, home health, medical equipment and some specialist visits. Your doctor sends the request, the plan says yes or no, and the care waits for that answer.

Most requests get approved. Timelines differ by plan, though, and you can appeal a denial, first to the plan and then to an outside reviewer. If you get a denial, we can help you work through the appeal.

Original Medicare with a Medigap plan has very little prior authorization. If that matters more to you than a low premium, tell us at the start. It changes what we'd suggest.

Our process

How we check a St. Louis provider network

  1. 1

    You give us your list

    Your family doctor, each specialist, the hospital you'd want and your pharmacy. Names and office locations are plenty.

  2. 2

    We look at this year's directory

    We check every Advantage plan we represent against your list for the coming plan year, not last year's.

  3. 3

    We call the office if it's unclear

    Plan directories get things wrong. Sometimes a quick call to the front desk is the only way to know for sure.

  4. 4

    You get a plain answer

    Which of our plans keep all of your providers, which keep some, and what the gaps would cost.

We do not offer every plan available in your area

Our check covers the companies we represent. For details on every plan sold in the St. Louis area, contact Medicare.gov, 1-800-MEDICARE, or Missouri SHIP at 800-390-3330.

Local networks

Advantage networks around St. Louis

St. Louis Advantage networks are built around four hospital groups. BJC has Barnes-Jewish Hospital in the Central West End, Missouri Baptist Medical Center in Town and Country, Christian Hospital in North County and Barnes-Jewish St. Peters in St. Charles County. Mercy has Mercy Hospital St. Louis in Creve Coeur and Mercy Hospital South. SSM Health has Saint Louis University Hospital, DePaul in Bridgeton, St. Clare in Fenton and St. Joseph in St. Charles. St. Luke's Hospital in Chesterfield is independent. Veterans may also use the John Cochran or Jefferson Barracks VA medical centers.

The plans on sale also aren't the same everywhere. A plan offered in St. Louis County may not be sold in St. Charles County, or the reverse, so we always start with your ZIP code. See all the places we help on our service areas page, or go back to the St. Louis Medicare overview.

Fit

When Advantage works well, and when it doesn't

It usually fits if you

  • Already get your care inside one St. Louis hospital system
  • Want a low or $0 plan premium
  • Like having a firm cap on a bad year
  • Will use the dental, vision, hearing or fitness extras
  • Don't mind copays and the occasional referral

It usually doesn't fit if you

  • See doctors at more than one system, like BJC and Mercy
  • Have several specialists and want steady, flat bills
  • Are in the middle of treatment and can't risk a network change
  • Don't want approvals holding up your care
  • Spend months each year out of state

Before you sign

What to ask about any Advantage plan

Will all of my doctors be in network next year?
Ask about each one by name, and ask about your hospital as well. A plan might keep your family doctor but drop the cardiologist or surgeon you count on.
What is the yearly out-of-pocket maximum, in dollars?
That's the most you'd pay for in-network care in a bad year. Line it up across plans, because two plans in the same ZIP code can be thousands of dollars apart.
What do I pay for a specialist, an outpatient surgery and a hospital stay?
Those three copays tell you more about a real year than the premium does. Get all three before you decide.
Do any of my drugs need prior authorization or step therapy?
Find out before you join. Step therapy means the plan may make you try a lower-cost drug first, even one that didn't work for you before.
How far will the dental allowance go for the work I need?
A big dental number in an ad often covers only certain services. Ask what the plan pays toward a cleaning, a filling and a crown.
How do I get out of this plan if it doesn't work?
You can change during Annual Enrollment or the Medicare Advantage Open Enrollment Period. Going back to Medigap later may mean answering health questions. Read about switching your plan.
