Why the Plan Type Matters
Two Medicare Advantage plans in the same county can operate very differently depending on their type. One might require you to pick a primary care doctor and get referrals for every specialist. Another might let you see any provider in the country who accepts the plan's terms. Understanding plan types is the foundation of choosing wisely.
According to Medicare & You 2026, HMO Plans are the most common type of Medicare Advantage plan. You must generally use doctors, hospitals, and other providers in the plan's network and service area, except in an emergency. You typically need to choose a primary care doctor (PCP) who coordinates your care and provides referrals to see in-network specialists. HMO plans usually have the lowest premiums of any Advantage plan type — and the most restrictions.
According to Medicare & You 2026, PPO Plans give you more flexibility. You can use providers both in and out of the plan's network — but you'll pay less if you use in-network providers. You generally don't need a referral to see a specialist. PPO plans are particularly well-suited for people who travel frequently, have established relationships with multiple specialists, or don't want to be locked into a single network. Premiums are typically higher than HMO plans.
According to Medicare & You 2026, Private Fee-for-Service Plans are a less common type of Medicare Advantage. The plan sets its own rates for what it pays providers and what you pay. You can see any Medicare-approved provider who agrees to the plan's payment terms and agrees to treat you — but providers are not obligated to do so. If you have a PFFS plan, you should confirm that your doctor accepts the plan's terms before each visit, as this can change. PFFS plans may or may not have a network of providers who have agreed in advance to treat plan members.
According to Medicare & You 2026, Medical Savings Account Plans combine a high-deductible Medicare Advantage Plan with a bank account. Medicare deposits money into your account each year, and you use those funds to pay for your health care costs. Once you've spent the money in your account, you pay out of pocket until you meet the plan's high deductible — after which the plan pays 100% for covered services. MSA plans do not include drug coverage (Part D), so you'd need to join a separate drug plan. These plans are most appropriate for people who are generally healthy and want a Medicare-funded savings component.
An MSA Plan is similar to a Health Savings Account — the key difference is that Medicare deposits money into your MSA, and you can use it for qualified medical expenses. However, once you have Medicare, you cannot make your own contributions to an HSA. MSA Plan deposits come from Medicare, not from you.
Special Needs Plans (SNPs)
Within the HMO and PPO structures, Medicare offers a distinct category called Special Needs Plans. According to Medicare & You 2026, these are tailored for people with specific diseases, conditions, or characteristics. They limit membership to people in those special categories and tailor their benefits, provider networks, and drug formularies to best serve those members.
There are three types of Special Needs Plans:
Chronic Condition SNP (C-SNP)
For people with specific chronic conditions like diabetes, heart failure, dementia, or end-stage renal disease. Benefits are designed around managing that condition.
Dual Eligible SNP (D-SNP)
For people who qualify for both Medicare and Medicaid. These plans coordinate between both programs and may eliminate most cost-sharing.
Institutional SNP (I-SNP)
For people living in an institution like a nursing home or long-term care facility, or who need nursing-home-level care at home.
Which plan types exist in your area depends entirely on which insurance companies operate in your county. Some rural counties may have only one or two Medicare Advantage options. Urban counties may have dozens. The best way to see what's available is at Medicare.gov/plan-compare, or to call Betsy — she knows the local landscape in MA, KY, and FL.
"For most of my clients, the choice really comes down to HMO vs. PPO — and the answer depends heavily on whether you snowbird or travel. If you're in Florida in the winter and Massachusetts in the summer, an HMO with a local network is going to leave you without non-emergency coverage for half the year. A PPO or Original Medicare with Medigap is a much better fit. I work through all of this with every client before we ever look at a specific plan."
