2026 Medicare Costs: What You Will Actually Pay
The standard Part B premium in 2026 is $202.90/month — up from $185 in 2025. Higher-income beneficiaries pay IRMAA surcharges starting at $109,000 single income. The annual Part B deductible is $283. Part A has no premium for most seniors but carries a $1,676 deductible per benefit period. The historic 2026 change is the $2,100 Part D drug cap — once you hit this, Medicare pays 100% for the rest of the year.
Medicare Enrollment Deadlines and Penalties
Your 7-month Initial Enrollment Period (IEP) spans 3 months before your 65th birthday month, your birthday month, and 3 months after. Missing it without qualifying employer coverage triggers a permanent 10% Part B penalty for every 12 months of delay. The General Enrollment Period (January 1 to March 31 each year) is your fallback if you missed IEP. Employees at companies with 20+ employees can delay Medicare while on active employer coverage and use an 8-month Special Enrollment Period afterward.
Medicare Advantage vs. Original Medicare: Which Is Right for You?
Medicare Advantage (Part C) plans are sold by private insurers. They bundle hospital, medical, and usually drug coverage with average premiums of $14/month in 2026 — but require you to use in-network providers and often require prior authorization. Original Medicare (Parts A+B) lets you see any Medicare-accepting provider nationwide with no referrals needed, but has no out-of-pocket maximum unless you add a Medigap plan. The right choice depends on your health status, medications, preferred doctors, and financial situation.
Medigap: Filling Medicare’s Gaps
Medigap (Medicare Supplement) plans pay costs Original Medicare doesn’t cover. Plan G is the most comprehensive for new enrollees — it covers the Part A deductible, Part B coinsurance, hospital costs, foreign travel emergencies, and skilled nursing coinsurance, for about $130–$200/month. Plan N costs $100–$160/month with small copays. Your guaranteed-issue window is the 6 months starting the month you turn 65 and enroll in Part B — after this window, insurers can medically underwrite you.
Part D Drug Coverage 2026
Every Medicare beneficiary needs Part D coverage unless they have equivalent drug coverage elsewhere. In 2026, the $2,100 annual out-of-pocket cap eliminates catastrophic drug costs for seniors on expensive specialty medications. Insulin is capped at $35/month. The Medicare Prescription Payment Plan (MPPP) lets you spread costs across monthly payments. If your income is below $22,590 single or $30,660 couple, you may qualify for Extra Help — worth up to $5,900/year in drug savings.
Frequently Asked Questions About Medicare
What is the Medicare Part B premium in 2026?
The standard Part B premium is $202.90/month in 2026. Higher-income beneficiaries pay IRMAA surcharges ranging from $244.60 to $614.90/month depending on their income two years prior (2024 income determines 2026 IRMAA).
When should I sign up for Medicare?
Sign up during your 7-month Initial Enrollment Period starting 3 months before your 65th birthday. Delaying without qualifying employer coverage creates permanent monthly penalties on your Part B premium for life.
Is Medicare Advantage or Original Medicare better?
Neither is universally better. Medicare Advantage suits healthier seniors who want low premiums and bundled benefits. Original Medicare + Medigap suits those with chronic conditions who want maximum provider choice and predictable costs.
How does the $2,100 Part D drug cap work?
Once your total out-of-pocket drug costs reach $2,100 in 2026, your Part D plan covers 100% of covered prescription costs for the rest of the calendar year. This replaces the old catastrophic coverage threshold and eliminates the coverage gap (donut hole).
