The Medicare Advantage Knowledge Gap

Medicare Advantage plans work extremely well for millions of Medicare beneficiaries — and poorly for others. The difference is almost never the plan itself. It’s whether the person enrolling understands how Medicare Advantage actually works.

What Medicare Advantage Is — and What It Is Not

Medicare Advantage (also called Medicare Part C) is a federally regulated Medicare program administered by private insurance companies.

When you enroll:
  • You are still in Medicare
  • Medicare pays the insurance company to manage your care
  • The plan must follow strict CMS rules
By law, Medicare Advantage plans must cover everything Original Medicare covers — at least as well. Many plans also include additional benefits.

Why Medicare Advantage Exists (Context Matters)

Medicare Advantage was created to:

  • Offer alternatives to Original Medicare
  • Control rising healthcare costs
  • Provide coordinated care models
  • Expand access to prescription drug coverage
  • Add cost protection through spending limits
It exists because Original Medicare alone has no out-of-pocket maximum and can expose beneficiaries to unlimited costs without a supplement.

Coverage

Medicare Advantage plans must cover all Medicare-approved services.

Access

Plans manage how and where those services are delivered through:

  • Copays for doctor and specialist visits
  • Daily hospital copays
  • Coinsurance for outpatient procedures
  • Out-of-network costs (if allowed)

Most dissatisfaction with Medicare Advantage comes from access expectations, not coverage gaps.

Networks: Why They Matter More Than Premiums

Medicare Advantage plans use provider networks. Depending on plan type:

  • HMO plans require in-network care and referrals
  • PPO plans allow more flexibility but still rely on preferred networks
Important realities:
  • Networks vary by region and ZIP code
  • Networks can change annually
  • Hospitals matter just as much as doctors
For people who want unrestricted provider choice, networks can feel limiting. For others, they provide structure and lower costs.

Understanding the True Cost of Medicare Advantage

Low or $0 premiums are real — but they are not the full story. Costs may include:

  • Copays for doctor and specialist visits
  • Daily hospital copays
  • Coinsurance for outpatient procedures
  • Out-of-network costs (if allowed)
The Built-In Spending Cap (A Major Advantage)
Medicare Advantage plans include an annual maximum out-of-pocket limit for medical services. Once that limit is reached: The plan pays 100% of covered medical costs for the rest of the year.

Original Medicare does not have this protection unless you add a Medicare Supplement.

Is Medicare Advantage Right for You?

Instead of asking “Is Medicare Advantage good or bad?” — ask: “How does Medicare Advantage fit the way I use healthcare?”

Plan G

Medicare Advantage may be a strong fit if you:
  • Want lower monthly premiums
  • Are comfortable with managed care
  • Prefer bundled coverage (medical + drugs)
  • Value a spending cap
  • Are open to reviewing your plan annually

May Not Be the Best Fit

It may be less ideal if you:
  • Want unrestricted provider access
  • See many specialists
  • Travel frequently across states
  • Prefer minimal administrative rules
  • Want long-term predictability above all else
This is when Medicare Supplement options are often explored.

Medicare Advantage FAQs

Straight Answers You Deserve
Yes. By law, Medicare Advantage plans must cover all medically necessary services that Original Medicare Part A and Part B cover. This requirement is written directly into their contract with Medicare. The difference is not what is covered — it’s how the coverage is accessed, such as networks, referrals, and prior authorizations.
Most complaints are about access and process, not coverage. Common frustration points include: a doctor leaving the network, referral requirements, prior authorization delays, and unexpected copays. These issues don’t mean care isn’t covered — they mean the plan has rules around how care is delivered.

No — and saying they are is misleading. Medicare Advantage plans work very well for millions of people. They work poorly when someone enrolls without understanding networks, prescription coverage, and how referrals and authorizations work. The plan isn’t the problem — the fit is.

Medicare Advantage plans are local plans. They are built around local hospitals, local doctor groups, and regional healthcare costs. That’s why a plan that works great in one county may be unavailable — or ineffective — in another. This is also why national TV ads can be misleading.

Do Medicare Advantage plans really cover everything Original Medicare covers?HMO plans usually require referrals and limit care to in-network providers (except emergencies). PPO plans allow more flexibility and may cover out-of-network care at higher cost. Neither is “better.” The right choice depends on how important provider flexibility is to you.

Most do — especially for imaging (MRI, CT scans), surgeries, infusions, and skilled nursing facility stays. This is common in managed care. Some people are comfortable with this structure; others prefer fewer administrative steps.

Yes — and this is one of their biggest advantages. Medicare Advantage plans include an annual maximum out-of-pocket limit for medical services. Once you reach it, the plan pays 100% of covered medical costs for the rest of the year. Original Medicare does not have this protection unless you add a Medicare Supplement.

Most Medicare Advantage plans include Part D prescription drug coverage. In many areas, Medicare Advantage drug coverage is as good as or better than standalone Part D plans — but this varies by plan and medication list. Prescription coverage should always be reviewed drug by drug, not assumed.

Medicare Advantage plans are renewed annually with Medicare. Each year, insurance companies may adjust doctor networks, drug formularies, copays, and out-of-pocket limits. This is why reviewing your plan every year is critical — even if nothing changed for you personally.

Yes, but when you can switch matters. Most people can change plans during the Annual Enrollment Period (fall) and the Medicare Advantage Open Enrollment Period (early in the year). Certain life events may also trigger Special Enrollment Periods.

It often is — monthly. Medicare Advantage usually has lower premiums, while Medicare Supplements typically cost more monthly but offer more predictable medical costs. The better option depends on budget, health usage, comfort with networks, and desire for predictability.

That depends on your doctors and hospitals, your prescription medications, your travel habits, your budget, and how you prefer healthcare to work. There is no universal answer — only a right fit.

Medicare Advantage Glossary

Clear Definitions for Common Medicare Terms — so you can feel confident, not confused.

Annual Enrollment Period

The time each fall (October 15 – December 7) when most Medicare beneficiaries can change Medicare Advantage or Part D plans for the following year.
