What are you really comparing in a Medicare plan comparison?

A Medicare plan comparison weighs how each coverage path pays for medical care and prescriptions, where you can receive care, and what financial risk stays with you during the year.

Original Medicare means Part A hospital insurance and Part B medical insurance administered through the federal program. You may keep Original Medicare by itself, add a standalone Part D prescription drug plan, and potentially buy a Medicare Supplement policy. Or, you may choose a Medicare Advantage plan, also called Part C, which is offered by a private insurer and becomes the way you receive your Part A and Part B benefits.

The comparison has two main paths:

1. Original Medicare + Medigap + Part D. A Medicare Supplement, often called Medigap, is private insurance designed to help pay certain out-of-pocket costs left by Original Medicare. It does not include outpatient prescription drug coverage, so most people who want drug coverage add a separate Part D plan.
2. Medicare Advantage. A Medicare Advantage plan generally bundles Part A and Part B coverage and may include Part D coverage and extra benefits. You still pay your Part B premium, and the plan sets its own provider network, cost sharing, authorization requirements, and annual out-of-pocket maximum for covered Part A and Part B services.

Start with the coverage route before comparing plan names. A low monthly premium can be valuable, but it does not tell you whether your specialist is in network, whether a medication faces a coverage restriction, or what you could pay after a hospitalization. This sequence keeps the comparison focused on the care and financial exposure that matter most to you.

For a clear overview of the available paths, review Arizona Medicare plan options before narrowing your choices.

How should an Arizona Medicare plan comparison start with your doctors and prescriptions?

An Arizona Medicare plan comparison should begin with a written list of your doctors, facilities, medications, preferred pharmacies, and expected care—not with a television commercial or a benefit headline.

Check doctors and facilities by plan, not by insurer

A carrier can offer several plans with different networks in the same county. Confirm each primary care doctor, specialist, hospital, outpatient center, and preferred pharmacy under the specific plan name and plan year you are considering.

With an HMO Medicare Advantage plan, you usually need to use in-network providers for non-emergency care and may need a referral for specialists. PPO plans typically offer some out-of-network access, but your cost is generally higher and providers may not accept the plan. Plans also may require prior authorization, which is the plan’s advance approval before it agrees to cover certain services, equipment, tests, or treatments.

Original Medicare generally gives you broader access to providers that accept Medicare, which can matter if you see specialists in Phoenix, Tucson, Flagstaff, or another area outside your home county. A Medicare Supplement policy can make your share of approved Original Medicare costs more predictable, but it does not create prescription coverage.

Run every medication through the plan formulary

A formulary is a plan’s covered-drug list. Each drug is assigned to a cost tier, and the plan can apply rules such as prior authorization, step therapy, or quantity limits.

Use the exact drug name, dosage, frequency, and whether you take brand-name or generic medication. Then compare:

• Whether the drug is covered;
• Its tier and estimated pharmacy cost;
• Whether the plan requires approval or trying another drug first;
• Whether your pharmacy is preferred, standard, mail-order, or out of network; and
• Whether coverage changes at different stages of your Part D benefit.

A plan that covers all your prescriptions can still be a poor fit if your pharmacy is not preferred or if a high-cost medicine has a restrictive rule. Recheck prescriptions during each Annual Enrollment Period because formularies, pharmacy contracts, tiers, and premiums can change from one plan year to the next.

What is the practical difference between Medicare Advantage, Medigap, and Part D?

Medicare Advantage trades some provider flexibility for a plan-based structure, while Medigap works with Original Medicare to reduce approved medical cost sharing and Part D handles outpatient prescriptions.

| Coverage approach | Doctors and hospitals | Monthly-cost pattern | Medical cost exposure | Prescription coverage | Best fit to explore when | |---|---|---|---|---|---| | Original Medicare only | Broad access to providers that accept Medicare | Part B premium; no Medigap or Part D premium | You remain responsible for deductibles and coinsurance; no annual out-of-pocket ceiling for Original Medicare alone | None | You have other creditable drug coverage or a specific reason not to add coverage | | Original Medicare + Medigap + Part D | Broad access to Medicare-accepting providers nationwide | Part B premium plus Medigap and Part D premiums | Medigap may pay some or most approved Original Medicare cost sharing, depending on the policy | Separate Part D plan | You value provider choice, travel flexibility, and predictable medical bills | | Medicare Advantage with drug coverage | Usually network-based; rules vary by HMO or PPO | Part B premium plus any plan premium | Copays and coinsurance apply until the plan’s annual medical out-of-pocket maximum | Often included | Your doctors and medications fit the plan and you are comfortable following its network and plan rules |

No approach wins for every Arizona resident. Your decision should reflect the costs you can absorb, the care you use, and whether you want plan networks to guide where you receive non-emergency care.

Medigap policies are standardized by letter in many cases, meaning policies with the same letter provide the same core benefits regardless of carrier. Premiums, rating methods, household discounts, underwriting, service experience, and availability can still differ. You can learn more about Medicare Supplement plans in Arizona before deciding whether this route fits your needs.

One major timing issue deserves attention: your ability to buy a Medigap policy without medical underwriting is strongest during your Medigap Open Enrollment Period, which begins when you are both 65 or older and enrolled in Part B. Outside protected enrollment situations, an insurer may use health underwriting when you apply. Do not drop a current policy until you understand acceptance, effective dates, and replacement rules.

How much should a Medicare plan comparison focus on budget?

Your budget comparison should total predictable premiums and likely point-of-service costs, then test the worst reasonable medical year you could face.

For each option, list your Part B premium first. Then add any Medicare Advantage, Medigap, and Part D premiums. Next, estimate costs for the care you know you use: specialist appointments, imaging, therapy, outpatient procedures, durable medical equipment, and medications.

Then ask the harder question: “What happens if I have a serious diagnosis, surgery, or extended outpatient treatment?” Medicare Advantage plans have an annual limit on your covered Part A and Part B out-of-pocket costs, but that limit does not generally include Part D drug costs or monthly premiums. Original Medicare by itself does not have a comparable annual cap. A Medigap policy can reduce eligible Original Medicare cost sharing, but you pay a separate premium for that protection.

Do not compare only copays. Compare the plan’s evidence of coverage for deductibles, inpatient stays, skilled nursing care, ambulance services, diagnostic testing, chemotherapy or infusion treatment, rehabilitation, and prior authorization rules. A licensed agent can help you organize these details in a straightforward worksheet rather than relying on a generic Medicare plan comparison calculator.

How do travel and Arizona county availability affect your choice?

Travel needs can change which Medicare plan is practical, especially if you split time between Arizona and another state or regularly seek specialty care outside your county.

Medicare Advantage plans are county-based. A plan available in Maricopa County may not be offered in Yavapai, Pima, Mohave, or Yuma County, and provider networks can differ even when a carrier operates statewide. Emergency and urgently needed care have protections, but routine care away from home may be limited by the plan’s network and service area.

Original Medicare with a Medicare Supplement is often worth comparing if you want the ability to see Medicare-accepting providers across the country without relying on a local plan network. Foreign travel coverage is limited under Original Medicare; some Medigap policies may include a limited foreign travel emergency benefit. Read the policy details rather than assuming any plan covers routine care abroad.

If you move permanently outside a plan’s service area, you may qualify for a Special Enrollment Period. A Special Enrollment Period is an opportunity to change coverage outside the normal enrollment window after certain life events, such as a move, loss of other coverage, or a qualifying change in eligibility. The event, notice requirements, and timing matter, so address a move before your coverage gap becomes a problem.

When can you compare and change Medicare plans in Arizona?

You can compare plans year-round, but the date you enroll or change coverage determines which choices are available and when they take effect. In practical terms, research can happen at any time, while enrollment changes must follow the window that applies to your situation.

Your Initial Enrollment Period is generally a seven-month window around the month you become eligible for Medicare at age 65. Enrollment timing can affect Part B and Part D late-enrollment penalties if you do not have qualifying coverage from active employment.

For plan changes, the Annual Enrollment Period runs from October 15 through December 7 each year. Since it is October 10, 2026, Arizona residents preparing for 2027 coverage should gather doctor and prescription information now and be ready to review plan materials when the enrollment period opens. Changes made during that window generally take effect January 1.

The Medicare Advantage Open Enrollment Period runs from January 1 through March 31. If you are already enrolled in a Medicare Advantage plan, you may make one change to another Medicare Advantage plan or return to Original Medicare and add a Part D plan during that period. It is not a general enrollment period for every Medicare choice.

Plan benefits, premiums, drug formularies, and networks can change annually. A yearly review is especially wise if you received an Annual Notice of Change, started a new medication, lost a doctor from your network, moved, or expect different care next year. Our Medicare coverage review guidance explains why a plan that worked last year may not be your best option now.

Frequently asked questions

What are the four types of Medicare plans?

The four parts of Medicare are Part A for hospital insurance, Part B for medical insurance, Part C for Medicare Advantage plans offered by private insurers, and Part D for outpatient prescription drug coverage. Medicare Supplement policies are separate private policies that work with Original Medicare and are not a Medicare “part.”

Is GoodRx better than Medicare Part D?

GoodRx-style discount pricing is not better or worse than Part D because it is not insurance and does not provide the same protection. You can compare cash-discount prices with your Part D price, but you generally cannot use both for the same prescription claim, and purchases made outside Part D usually do not count toward your plan’s drug spending protections.

Why do some people stay away from Medicare Advantage plans?

Some people avoid Medicare Advantage because provider networks, referrals, prior authorization, and annual plan changes can limit flexibility for non-emergency care. Medicare Advantage can still be a strong fit when your doctors and prescriptions are covered, you understand the plan rules, and its cost structure matches your budget.

What are six things Medicare does not cover?

Original Medicare generally does not cover routine dental care, routine eye exams and most eyeglasses, hearing aids and routine hearing exams, custodial long-term care, most care outside the United States, and cosmetic surgery that is not medically necessary. Medicare Advantage plans or separate policies may offer some additional benefits, but coverage limits and rules vary by plan.

Can I have Medicare Advantage and a Medigap policy at the same time?

No. It is generally not useful or permitted to sell a Medigap policy to someone enrolled in Medicare Advantage because Medigap pays after Original Medicare, not after a Medicare Advantage plan. You must return to Original Medicare before a Medigap policy can provide its intended benefits.

How do I compare Medicare Part D plans for 2027?

Compare 2027 Part D plans by entering every medication, dosage, and pharmacy into the plan comparison tool once 2027 information is available, then reviewing total estimated annual drug costs, formulary tiers, pharmacy status, deductibles, and drug restrictions. Do not choose based only on the monthly premium.

Can I change my Medicare Supplement policy during Annual Enrollment?

You can apply to change a Medicare Supplement policy at other times, but the Annual Enrollment Period does not automatically give you a right to switch Medigap policies without underwriting. Ask about eligibility, medical underwriting, premium changes, and whether you have a guaranteed-issue right before canceling existing coverage.

Do Medicare plans work the same way everywhere in Arizona?

No. Medicare Advantage and Part D plan availability, provider networks, pharmacy pricing, and premiums can vary by Arizona county. Original Medicare rules are national, while Medigap policy availability and pricing also depend on the insurer and your application circumstances.
