Question 1

How much does Medicare cost per month in 2026?

Accepted Answer

For most people: Part A is free (if you worked 40+ quarters). Part B is $185/month (base premium in 2026). Part D varies by plan, averaging $40–$60/month. A Medicare supplement (Medigap Plan G) runs $120–$250/month depending on age and location. Total for typical retiree: $350–$500/month covering most medical costs. High earners pay IRMAA surcharges on top of base Part B and D premiums, potentially pushing total Medicare costs to $600–$900/month or more.

Question 2

What is IRMAA and will I owe it?

Accepted Answer

IRMAA (Income-Related Monthly Adjustment Amount) adds surcharges to your Part B and Part D premiums if your Modified Adjusted Gross Income from 2 years ago exceeded $106,000 single or $212,000 married. In 2026, IRMAA uses your 2024 income. The surcharge tiers go from +$74/month all the way to +$443.90/month for very high earners. A single retiree with 2024 income of $133,000–$167,000 pays $370/month for Part B instead of $185. If your income has dropped since 2024 (due to retirement), appeal using SSA Form SSA-44.

Question 3

Should I choose Medicare Advantage or Original Medicare with Medigap?

Accepted Answer

Medicare Advantage (Part C) offers lower premiums, often $0, but restricts you to a network and typically requires referrals and prior authorizations. Original Medicare with Medigap has higher premiums ($150–$300/month for a good supplement plan) but gives you access to any Medicare-accepting provider nationwide — critical for frequent travelers, people with complex health conditions, or anyone who values flexibility. People who are healthy and local often do well with Advantage; those with chronic conditions or specialists often prefer Original Medicare + Medigap.

Question 4

Can I delay Medicare enrollment if I'm still working?

Accepted Answer

Yes — if you're covered by employer insurance through active employment (yours or your spouse's), you can delay Part B without penalty. Once you lose that employer coverage, you have an 8-month Special Enrollment Period to sign up penalty-free. COBRA and retiree health insurance do NOT count as active employer coverage for this purpose. If you delay without qualifying employer coverage, you face a 10% permanent premium penalty for each 12-month period you were eligible but didn't enroll.

Question 5

What does Medicare actually cover — what are the gaps?

Accepted Answer

Medicare Parts A and B cover hospitalizations, doctor visits, outpatient care, and preventive services — but with significant gaps. Part A: $1,676 deductible per benefit period (2026), then $419/day for days 61–90 in hospital. Part B: 20% coinsurance after the $257 deductible with no out-of-pocket maximum. No coverage for dental, vision, or hearing (the biggest gaps). Medigap plans fill most of these cost-sharing gaps; Medicare Advantage plans often include dental, vision, and hearing with varying coverage levels.

Part	What It Covers	2026 Premium
Part A	Hospital, skilled nursing, hospice	$0 (if 40+ work quarters)
Part B	Doctors, outpatient, preventive	$185/month base
Part D	Prescription drugs	~$40–$60/month (plan varies)
Medigap G	Fills A+B cost gaps	$120–$250/month (age/location)
Medicare Advantage	Replaces A+B+D	Often $0–$100/month
