01
Six-month open enrollment
This is the strongest time to shop for Medigap because medical underwriting cannot be used to deny the policy during the protected window.
Start with the structure
These are two different ways to build Medicare coverage
Medicare Advantage changes who administers your Part A and Part B benefits. Medicare Supplement insurance stays with Original Medicare and helps pay specified Medicare cost-sharing.
| Question | Medicare Advantage | Medicare Supplement |
|---|---|---|
| How do you receive Part A and Part B benefits? | Through a Medicare-approved private plan. | Through Original Medicare. The Medigap policy pays according to its standardized benefits after Medicare processes the claim. |
| Provider access | Often uses a plan network. HMO and PPO rules differ. | Standard Medigap follows Original Medicare provider access. Medicare Select policies can use network requirements for some care. |
| Prescription drugs | Most plans include Part D. | Medigap policies sold today do not include Part D. If you need drug coverage with Original Medicare, you can join a separate Medicare drug plan. |
| Medical out-of-pocket structure | The plan has a yearly maximum for covered Part A and Part B services. | The policy pays specified Original Medicare cost-sharing based on the standardized plan letter you own. |
| Extra benefits | Plans may include dental, vision, hearing, fitness, and other extras. | Medigap is focused on supplementing Original Medicare cost-sharing. Extra services are not its core purpose. |
Direct answer
No, Medigap does not work with Medicare Advantage
A Medigap policy cannot be used to pay Medicare Advantage copays, deductibles, or premiums. A company cannot sell you a Medigap policy while you are enrolled in Medicare Advantage unless you are switching back to Original Medicare.
Do not cancel Medigap until you understand your right to get it back
If you drop a Medigap policy to join Medicare Advantage, do not assume you can buy the same coverage later. Federal and Texas guaranteed-issue rights apply in specific situations, including certain first-time Medicare Advantage trial rights. Outside a protected enrollment right, an insurer may use medical underwriting.
Texas Medigap timing
Your Medigap enrollment window can change the decision
For Texans age 65 or older, the one-time Medigap Open Enrollment Period lasts six months and begins when Part B starts. During that period, companies selling Medigap in Texas must offer coverage without denying you because of your health history.
02
Guaranteed-issue events
Loss of certain coverage, plan termination, moving out of some plan service areas, and specific trial rights can create another protected opportunity. The exact right and deadline depend on the event.
03
Outside protected rights
After your protected window ends, your ability to buy or switch Medigap can be limited. Do not leave existing coverage until you know what you can obtain next.
What to compare
Compare the delivery system, not the marketing headline
The best comparison is built around your providers, travel pattern, prescriptions, budget, and tolerance for plan rules.
Medicare Advantage may fit when
You are comfortable with the plan's network and authorization rules, the plan includes your prescriptions, the expected costs fit your budget, and you value having medical and drug coverage combined in one plan.
Original Medicare plus Medigap may fit when
You place a high value on broad Medicare provider access, you are comfortable paying a separate Medigap premium, and you want the standardized Medigap benefit structure rather than a Medicare Advantage network.
There is no universal winner
The right choice can be different for two spouses living in the same house. Medicare coverage is individual, and each person should compare the option against their own doctors, medications, travel, health needs, and budget.
