📚 2026 US Medicare IRMAA Brackets & Medigap Plan G vs Medicare Advantage Guide
Medicare beneficiaries whose Modified Adjusted Gross Income (MAGI) from two years prior exceeds statutory thresholds ($106,000 Single / $212,000 Married Filing Jointly) pay an Income-Related Monthly Adjustment Amount (IRMAA) on both Medicare Part B and Part D prescription drug plans. Furthermore, choosing between Medigap Plan G (which covers 100% of Medicare Part A and Part B coinsurance after a small $257 annual deductible) and Medicare Advantage (Part C) determines your maximum out-of-pocket exposure during hospitalization or cancer treatment.
