Choosing Wisely: Cost Breakdown of Medicare Advantage vs. Original Medicare + Medigap


Based on readers’ interest, huutri.org has decided to provide a detailed cost breakdown to help retirees clearly understand the potential financial differences between Medicare Advantage and Original Medicare with Medigap. By comparing a typical “normal year” and a “high-cost year,” this breakdown aims to guide retirees in choosing the plan that best fits their medical needs, budget, and long-term peace of mind.

Appendix: Cost Comparison Tables (Numerical)
This is an illustrative example of costs in a normal year and a high-cost medical year, helping retirees visualize the difference between Medicare Advantage and Original Medicare with Medigap.

Note: These are only average estimates. Actual costs may vary by region, plan choice, age, and health status.

Scenario 1: Normal Year (Moderate Medical Use)
Assumptions:

  • Several doctor visits, routine lab tests
  • One short hospitalization
  • Some prescriptions
Cost Component Alice (Medicare Advantage) Bob (Original Medicare + Medigap)
Part B Premium (monthly) $185 × 12 = $2,220 $2,220
MA Plan Premium $25/month → $300/year
Medigap Premium ~$150/month → $1,800/year
Deductibles / Copays ~$500–$2,000/year Very low (most covered by Medigap)
Drug Costs Within 2025 Part D $2,000 cap Also within $2,000 cap

Estimated Total:

  • Alice (MA): $2,220 + $300 + ~$1,000 = ~$3,520
  • Bob (Medigap): $2,220 + $1,800 + ~$300 = ~$4,320

In a low-use year, Medicare Advantage may cost less due to lower monthly premiums.

Scenario 2: High-Cost Year (Cancer Treatment, Multiple Hospital Stays, Surgeries)
Assumptions:

  • Multiple hospital admissions
  • Cancer treatment (radiation, chemo, surgery)
  • Expensive medications
  • Bob chooses to receive care at an out-of-state hospital (e.g., MD Anderson in Texas)
Cost Component Alice (Medicare Advantage) Bob (Original Medicare + Medigap)
Part B Premium $2,220 $2,220
MA / Medigap Premium $300 $1,800
Deductibles & Cost Sharing May hit the annual out-of-pocket maximum of $9,350 (for in-network services) Medigap covers nearly all cost sharing, keeping expenses low
Drug Costs $2,000 (2025 cap) $2,000
Out-of-Network Care (e.g. MD Anderson) May be denied → full out-of-pocket cost (can be tens of thousands) Covered if the facility accepts Medicare

Estimated Total:

  • Alice (MA): $2,220 + $300 + $9,350 + $2,000 = ~$13,870 (not counting any fully out-of-pocket costs for denied out-of-network care)
  • Bob (Medigap): $2,220 + $1,800 + ~$2,000 = ~$8,020 (while still having freedom to choose where to receive treatment)

In a high-cost year, Medigap helps minimize financial risk and preserves provider choice.

Conclusion from the Cost Tables

  • Medicare Advantage can save money in years with low medical usage, but carries greater financial risk if you need expensive or out-of-state care.
  • Original Medicare + Medigap requires higher monthly premiums but provides predictability, stability, and nationwide choice for hospitals and specialists.
