What’s Going On With Medicare Advantage Plans? Understanding the Changes to HMOs and PPOs
If you’ve been hearing that Medicare Advantage plans are changing, you’re not imagining it. Across the country, many beneficiaries are discovering that their plans have been discontinued, benefits have been reduced, or favorite doctors are no longer in network. So, what is happening?
A Changing Medicare Advantage Landscape
For years, Medicare Advantage plans have grown rapidly in popularity. Seniors were attracted to low or even $0 monthly premiums, prescription drug coverage, annual out-of-pocket maximums, and extra benefits such as dental, vision, hearing, fitness memberships, and over-the-counter allowances.
However, 2026 has become a turning point for the industry.
Insurance companies are facing rising healthcare costs, increased utilization of medical services, and changes in government reimbursement formulas. As a result, many carriers are reevaluating their Medicare Advantage offerings.
Why Are Plans Changing?
Several factors are driving these changes:
1. Higher Medical Costs
People are using more healthcare services than insurers anticipated. Increased hospitalizations, specialist visits, and outpatient procedures have significantly raised costs for Medicare Advantage carriers.
2. Changes in Medicare Funding
The Centers for Medicare & Medicaid Services (CMS) have adjusted payment formulas and implemented new regulations affecting Medicare Advantage plans. Many insurers say reimbursement increases have not kept pace with actual healthcare expenses. (Centers for Medicare & Medicaid Services)
3. Prescription Drug Changes
The redesign of Medicare Part D and implementation of the Inflation Reduction Act have shifted some financial responsibility to insurance companies, adding additional pressure to plan profitability.
What Does This Mean for HMO Plans?
Health Maintenance Organizations (HMOs) typically require members to use a defined network of doctors and hospitals and often require referrals to see specialists.
Because HMOs allow insurers to coordinate care more closely and manage costs, many carriers are placing greater emphasis on HMO products.
For beneficiaries, this may mean:
• More HMO options available in certain areas.
• Narrower provider networks.
• Increased emphasis on primary care coordination.
• Lower premiums compared to PPO plans.
The trade-off is less flexibility when seeking care outside the network.
What About PPO Plans?
Preferred Provider Organizations (PPOs) have traditionally been popular because they allow beneficiaries to see providers both inside and outside the network without referrals.
Unfortunately, PPO plans have been among the hardest hit by recent changes.
Many carriers have:
• Eliminated PPO plans entirely in certain counties.
• Reduced the number of $0 premium PPO offerings.
• Increased copayments and coinsurance.
• Narrowed provider networks.
• Reduced supplemental benefits.
Industry analyses show a significant decline in $0 premium PPO offerings for 2026 as insurers attempt to control costs. (Milliman)
Are People Losing Their Plans?
In some cases, yes.
Millions of Medicare beneficiaries have received notices that their plans will not renew for the following year or that service areas have changed. These individuals must choose a new Medicare Advantage plan or consider returning to Original Medicare during eligible enrollment periods. (actuary.info)
This does not mean Medicare Advantage is disappearing. It does mean consumers need to review their Annual Notice of Change (ANOC) carefully each year.
What About Prior Authorization?
One of the biggest concerns surrounding Medicare Advantage has been prior authorization.
Many beneficiaries and physicians have expressed frustration over delays in obtaining approval for certain tests, procedures, and treatments.
CMS has implemented new requirements intended to improve transparency and strengthen appeal protections. Plans must follow stricter standards regarding medical necessity determinations and appeals processes. (American Hospital Association)
Even so, beneficiaries should continue to ask questions, understand authorization requirements, and appeal denials when appropriate.
Is Medicare Advantage Still a Good Choice?
The answer depends on the individual.
Medicare Advantage remains an excellent option for many people, especially those who:
• Prefer lower monthly premiums.
• Want built-in prescription drug coverage.
• Value annual maximum out-of-pocket protection.
• Are comfortable using provider networks.
• Appreciate extra benefits like dental and vision coverage.
However, beneficiaries who prioritize unrestricted provider choice, travel frequently, or have complex medical needs may want to carefully compare Medicare Advantage plans with Original Medicare combined with a Medicare Supplement plan.
The Bottom Line
Medicare Advantage is evolving.
The days of assuming that last year’s plan will automatically be the best choice for next year are over. Annual reviews have become more important than ever.
Beneficiaries should compare plans each year, verify that their physicians remain in network, review prescription drug formularies, and evaluate whether an HMO or PPO best fits their healthcare needs and lifestyle.
The good news is that choices still exist. The key is understanding the changes and working with a knowledgeable Medicare professional who can help navigate this increasingly complex marketplace.
Medicare isn’t one-size-fits-all. The best plan is the one that meets your unique health needs, budget, and priorities.
