Medigap or Medicare Advantage? How Tucson retirees decide
Premiums are only part of the story. Here is how networks, travel, health and budget shape the choice in southern Arizona.

It is the question we hear most at seminars: should I get a Medicare Supplement or a Medicare Advantage plan? There is no single right answer, but there is a right answer for you, and it usually becomes clear after looking at four things: where you get care, how you travel, your health outlook and your monthly budget.
How the two paths work
A Medigap plan sits on top of Original Medicare. Medicare pays its share of a covered bill, and your supplement pays most or all of the rest. You can see any doctor in the country who accepts Medicare, with no referrals and no networks. You will also need a separate Part D plan for prescriptions.
A Medicare Advantage plan replaces the way Original Medicare pays claims. A private insurer handles everything, usually including prescriptions, with copays for services and a yearly out-of-pocket maximum. Most plans use HMO or PPO networks and many include dental, vision, hearing and fitness benefits.
Where you get care
In Tucson, hospital loyalty runs deep. Some people have seen the same Banner cardiologist for a decade, while others would only ever go to TMC. Advantage networks differ from plan to plan, so the first step is always to confirm that your doctors and hospital are in network. If they are not, Medigap may be the simpler path.
How you travel
Many of our clients spend summers in Flagstaff, Colorado or the Midwest. Advantage plans cover emergencies anywhere, but routine care outside the service area is limited, especially on HMO plans. If you spend months away each year, a Medigap plan or a national PPO is usually more comfortable.
- Home year-round in Pima County: Advantage plans are often a strong value.
- Two to four months away: consider a PPO with national travel benefits.
- Half the year in another state: Medigap plus Part D is usually the cleanest choice.
Your health outlook
No one can predict the future, but some things are known. If you have a planned knee replacement, ongoing cancer care or regular specialist visits, the predictable costs of Medigap Plan G can be reassuring. If you are healthy and mostly need preventive care, an Advantage plan's low premium and extras can make more sense.
One timing detail matters here. In Arizona, once your six-month Medigap Open Enrollment Period ends, most insurers can ask health questions if you want to switch into a supplement later. That makes the first decision more important than it looks.
Pick the plan for the year you are worried about, not only the year you expect.
Your budget
Compare total yearly cost, not just premiums. For Medigap, add the supplement premium, the Part D premium and your expected drug costs. For Advantage, add any plan premium, typical copays and drug costs, and look at the out-of-pocket maximum as your worst case.
- Sample Medigap path: Plan G around $140 per month plus a Part D plan around $30, with very few bills after the Part B deductible.
- Sample Advantage path: $0 premium plan with $10 to $45 copays and a maximum out-of-pocket around $5,900.
- These are sample figures for illustration. Your quote depends on age, ZIP code and plan.
Making the call
When clients sit down with us, we build both paths side by side using their own doctors, drugs and travel plans. Usually one clearly fits better. If you would like that comparison, it is free, and there is never any obligation to enroll.
