What Types of Medicare Advantage Plans Are Available?

You can choose among several types of MA plans. Most plans use a network of physicians and healthcare facilities that have contracted with the insurance company. Your options may include:

  • Health maintenance organizations (HMOs): With this plan type, you are typically required to seek treatment from in-network providers unless it’s an emergency. If you visit an out-of-network provider, you may be responsible for the costs. Usually, you need a referral from your primary care physician to see a specialist. This is the most common type of MA plan. 
  • Preferred provider organizations (PPOs): With these plans, you pay less if you seek care from an in-network provider, but you can visit out-of-network providers as well. You typically don’t need a referral to see a specialist. 
  • Special needs plans (SNPs): These plans serve Medicare members with specific healthcare needs. There are three types of SNPs: 
    • Chronic condition special need plans (C-SNPs): This type of plan is for Medicare beneficiaries who have chronic health conditions, including diabetes, end-stage renal disease (ESRD) and cancer. 
    • Dual eligible special need plans (D-SNPs): This option is for people who are eligible for both Medicare and Medicaid. 
    • Institutional special need plans (I-SNPs): These plans are for nursing home residents and people who need nursing care at home. 
  • Private fee-for-service (PFFS) plans: With this plan option, you can see any healthcare provider who accepts the terms of your plan. Some PFFS plans have a provider network, and you pay less if you see someone in-network. 
  • Medical savings accounts (MSAs): This plan pairs a medical savings account with a high-deductible MA plan. Your deductible is the amount you pay for Medicare-covered services before your plan starts to pay. The plan adds funds to your MSA, and you can use those funds to pay for out-of-pocket costs. If you run out of funds in your MSA before you reach your deductible, you’re responsible for out-of-pocket costs until you reach your deductible.2

Thousands Enrolled

More than a third of eligible Missouri residents, or about 500,000, have signed up for a Medicare Advantage plan.

What Are Prescription Drug Options with Medicare Advantage?

Most MA plans include Medicare Part D (prescription drug coverage). If you choose an MSA plan and certain PFFS plans without Part D coverage, you can buy a separate Part D prescription drug plan. If you opt for an HMO or PPO without prescription benefits, you can’t buy a separate plan.3

Important: If you don’t buy Part D coverage when you’re first eligible, you may be required to pay an ongoing late enrollment penalty if you purchase Part D later.4 

How Do You Choose a Medicare Advantage Plan?

To choose a Missouri MA plan, consider the following:

  • Premiums: This is the monthly amount you pay for a plan. Plan premiums vary; some have a $0 premium, while others cost more. 
  • Other costs: Plans also have other out-of-pocket costs. Your deductible is the amount you pay for Medicare-covered services before your plan starts paying. Coinsurance is a percentage you pay for covered services and medical items after you’ve met your deductible. Copayments are a set dollar amount you pay for healthcare services and supplies and may apply before and/or after you’ve met your deductible.5 Finally, the out-of-pocket maximum is the most you’ll pay out of pocket for covered care each year.6 
  • Plan benefits: While all plans cover Medicare Parts A and B, and many include Part D, they vary when it comes to extra benefits. Plans may offer vision, dental and hearing care. Almost all offer telehealth, and some offer other perks like fitness programs and transportation to medical appointments.7 

Check the Costs

If you are considering a Medicare Advantage plan, be sure to look carefully at the costs, including deductibles, coinsurance, copayments and the out-of-pocket maximum, as well as the benefits.

When and How Do You Enroll in a Medicare Advantage Plan?

You can only enroll in MA plans at specific times, which are referred to as enrollment periods. They are: 

  • Initial enrollment: This period lasts for seven months, starting three months before the month you turn 65 and ending three months after that month. 
  • Open enrollment: Also referred to as an annual election period, it lasts from October 15 to December 7. During this period you can enroll in, switch or drop an MA plan. 
  • Medicare Advantage open enrollment: From January 1 to March 31 you can switch MA plans or drop your MA plan and go back to Original Medicare. 
  • General enrollment: If you start Medicare Part B between January 1 and March 31, you also can enroll in an MA plan. The coverage typically starts on July 1.8
  • Special enrollment: Certain life events and changes to your insurance entitle you to a special enrollment period. These include, but aren’t limited to:
    • Moving out of your plan’s service area
    • Losing or gaining coverage from Medicaid or an employer or union
    • Medicare terminating its contract with your MA plan
    • Being diagnosed with a health condition better served by an SNP9

To enroll in a plan, contact the insurance company you’re interested in or use the Medicare Plan Finder to compare plans and sign up.
