Medicare Advantage: The “Pay-as-You-Go” Model
Medicare Advantage plans are popular for their low upfront costs. In 2026, the average monthly premium is estimated at just $14, with many plans offering a $0 premium option.
Where You Save:
- Monthly Premiums: You keep more of your monthly income since premiums are minimal (though you still pay the standard $202.90 Part B premium).
- Bundled Benefits: Most plans include dental, vision, hearing, and prescription drug coverage (Part D) at no extra cost.
- Out-of-Pocket Cap: Your total annual medical spending is capped. For 2026, the maximum out-of-pocket (MOOP) limit is $9,350 for in-network services.
The Financial Catch:
You pay copays or coinsurance for almost every service (e.g., $40 for a specialist, 20% for outpatient surgery). If you have a year with major health issues, those “small” copays can quickly climb toward that $9,350 limit.
Medicare Supplement: The “Pre-Paid” Model
Medigap plans (like Plan G) act as a secondary insurance to Original Medicare. They don’t replace it; they “fill the gaps.”
Where You Save:
- Predictability: After you pay the annual $283 Part B deductible (2026 rate), a plan like Medigap Plan G typically covers 100% of your remaining Medicare-approved medical bills.
- No Network Restrictions: You can see any doctor in the U.S. that accepts Medicare, avoiding the “out-of-network” surcharges common in Advantage plans.
- Serious Illness Protection: If you require frequent specialist visits, dialysis, or chemotherapy, Medigap almost always saves you more than Advantage plans because there are virtually no copays.
The Financial Catch:
Medigap has higher monthly premiums, often ranging from $100 to $300+. You also have to buy a separate Part D prescription plan and usually pay out-of-pocket for dental and vision.
