Part A Premiums and Deductibles
Most Florida seniors pay $0/month for Part A after working 40+ quarters with Medicare taxes. If you have 30–39 quarters, you pay $284/month. Fewer than 30 quarters: $518/month.
Part A deductible in 2026: $1,676 per benefit period. This is not per year — it's per hospital stay separated by 60+ days. You could theoretically pay this deductible multiple times per year. Plan G and Plan N both cover this deductible entirely.
Part B Premium and Deductible
The 2026 standard Part B premium: $185.00/month. This is non-negotiable for most enrollees — Medigap does not cover the Part B premium.
Part B deductible: $257/year. This is the only cost Plan G does not cover (you pay it once annually, then Plan G covers everything above it). Plan N and HDG also require you to pay this deductible before coverage applies.
After the deductible, Medicare Part B covers 80% of approved costs. The remaining 20% is where Medigap protection matters most — there is no cap on this 20% under Original Medicare alone.
IRMAA Surcharges for Higher-Income Seniors
Income-Related Monthly Adjustment Amounts (IRMAA) add surcharges to both Part B and Part D premiums for seniors whose modified adjusted gross income (MAGI) exceeds thresholds based on income from 2 years prior.
2026 Part B IRMAA (based on 2024 individual income):
- Up to $106,000: $0 surcharge (standard $185/month)
- $106,001–$133,000: +$74.00/month
- $133,001–$167,000: +$185.00/month
- $167,001–$200,000: +$295.80/month
- $200,001–$500,000: +$406.90/month
- Over $500,000: +$443.90/month
Recently retired with lower current income? You can appeal IRMAA using Form SSA-44 to request a reduction based on your current income rather than 2024 income.
How Medigap Changes the Picture
Without Medigap, Original Medicare requires you to manage multiple cost-sharing obligations: Part A deductibles per stay, 20% of all Part B services with no cap, and daily coinsurance for extended hospital stays.
With Medigap Plan G, your cost-sharing simplifies to one number: $257/year (the Part B deductible). Every other Medicare-covered cost is handled by your plan. This predictability is what Florida seniors with Plan G consistently cite as the plan's greatest value — not just the money saved, but the elimination of financial uncertainty.
