Instead of participating in Original Medicare Parts A and B for hospital and general health care coverage, Missouri seniors can opt to enroll in Medicare Advantage, also known as Medicare Part C. Medicare Advantage provides seniors with a wide selection of plans through private insurers, which unlike Original Medicare, can include additional benefits such as vision, hearing, dental and prescription drug coverage. Participants in Medicare Advantage pay varying costs and receive differing coverage levels depending on the particular plan they select. Unlike Original Medicare where all participants receive the same level of coverage, Medicare Advantage participants can benefit from more comprehensive coverage tailored to their needs.

According to the Kaiser Family Foundation, approximately 39% of Missouri seniors enrolled in Medicare participate in a Medicare Advantage plan. This is an equivalent rate to the national average, and a higher percentage than many of the surrounding states. The closest states with higher rates of Medicare Advantage enrollment are Minnesota and Tennessee. States directly west of Missouri, such as Kansas and Nebraska, have lower rates of enrollment at 20% and 19%, respectively.

In this guide, we provide an overview of the different types of Medicare Advantage plans offered in Missouri, which include HMOs, PPOs, PFFS, MSAs and SNPs. Plans can range significantly in cost and coverage levels, allowing seniors to shop for a plan most amenable to their unique needs. Below, we also discuss prescription drug coverage options for Medicare Advantage participants, detail enrollment information and provide a list of resources seniors can access to better understand their health care options and ensure they select a plan that works for them.

About Medicare Advantage Plans in Missouri

Types of Medicare Advantage Plans

Multiple Medicare Advantage plan types are offered throughout Missouri.  Depending on what’s available in their area and their needs, Missouri Medicare beneficiaries may be able to choose from HMOs, PPOs, PFFS and MSA plans and SNPs. 

Health Maintenance Organizations (HMOs)

Seniors enrolled in an Health Maintenance Organization, or HMO, receive their health care benefits from a preferred list of network providers. If plan participants venture outside of this network to receive services from an out-of-network provider, their medical care costs will likely not be covered. HMOs typically require participants to select a primary care physician (PCP) whom they must see for regular medical visits. Specialist referrals are also typically required. While costs depend on the individual plan selected, HMOs are frequently the most affordable type of Medicare Advantage plan.

Preferred Provider Organizations (PPOs)

While seniors pay more to enroll in a Preferred Provider Organization, or PPO, plan than an HMO, these plans offer participants a little more flexibility. PPOs have a list of in-network providers from whom participants can receive full coverage, but the plan will typically also pay some portion of the costs if participants receive services from an out-of-network provider. Additionally, PPOs do not require seniors to designate a PCP, nor do they require referrals for specialist visits. 

Private Fee-For-Service Plans (PFFS)

PFFS plans typically offer seniors even more flexibility to decide which providers they would like to see. Some PFFS plans have a network of providers, and some do not, but in both cases, participants may see any provider that agrees to the plan’s payment terms and receive full coverage. PFFS plans generally have higher monthly premiums than HMOs or PPOs, and not all providers are willing to accept the payment terms of these plans.

Medical Savings Accounts (MSAs)

Some Missouri seniors may be able to enroll in a high-deductible Medicare Advantage plan called a Medical Savings Account (MSA). These plans deposit money into a savings account, and plan participants can then use those funds to pay for any health care services they receive until they reach the plan’s yearly deductible and their coverage kicks in.

Special Needs Plans (SNPs)

Special Needs Plans, or SNPs, are plans restricted to and provide tailored benefits for certain groups of people. In Missouri, nursing home residents, seniors with certain disabilities and individuals eligible for both Medicare and Medicaid may qualify for an SNP designated for their specific groups. Like HMOs, these plans have a network of preferred providers that participants must use to receive coverage.

Enrollment and Eligibility for Medicare Advantage in Missouri

Prior to enrolling in Medicare Advantage, seniors must first be enrolled in Original Medicare. Anyone who is eligible for Medicare Parts A and B is also eligible to enroll in Medicare Advantage. However, certain Medicare Advantage plans, such as SNPs, may have additional eligibility requirements.

Medicare Advantage has specific enrollment periods. One can only join a Medicare Advantage plan during the following periods:

  • Initial Coverage Election Period: This is the 7-month period during which everyone is eligible to enroll in a Medicare Advantage plan. The period spans from 3 months before the month of one’s 65th birthday to 3 months after one’s birthday month.
  • Annual Election Period (AEP): Also referred to as the Open Enrollment Period, the AEP runs from October 15-December 7 each year. During this period, anyone can enroll in Medicare Advantage for the first time or change to a new plan.
  • Medicare Advantage Open Enrollment Period: From January 1-March 31 each year, anyone who is already enrolled in Medicare Advantage can switch to a different plan, or disenroll and switch back to Original Medicare. This period is not open to anyone who is not currently enrolled in Medicare Advantage.
  • General Enrollment Period: In some circumstances, one can join Medicare Advantage between April 1-June 30. This enrollment period only applies to those who enrolled in Medicare Part B for the first time during Medicare’s Open Enrollment Period (January 1-March 31).

Additionally, Medicare Advantage plan participants can change their plan outside of these enrollment periods under certain qualifying circumstances, such as moving to a new state.

Prescription Drug Coverage

Missouri seniors enrolled in a Medicare Advantage plan may receive prescription drug coverage directly through their plan as a bundled Medicare Advantage-Prescription Drug (MA-PD) plan. Many HMOs and PPOs include this option. SNPs are federally mandated to include prescription drug coverage, and seniors with MSAs may opt to enroll in a separate Medicare Part D plan that specifically covers prescription drugs. PFFS plans may include prescription drug coverage or allow participants to enroll separately in a Medicare Part D plan. MA-PD plans may include prescription drug coverage in their standard monthly premium, while seniors with stand-alone Part D plans would need to pay premiums for both their Medicare Advantage and Part D plans.

Numerous resources are available throughout Missouri, both at the state and local level, to help seniors better understand their Medicare Advantage options and the sign-up process.
