To navigate Medicare, know Parts A (hospital) and B (medical): Part A is usually $0; Part B averages ~$185/month and covers 80% of approved costs. Choose between Medicare Advantage (private, networks, copays, possible $0 premiums) and Medigap (keeps Original Medicare, nationwide access, ~$150–$200/month). Factor IRMAA if you’re a higher earner. Time enrollment to avoid penalties; employer coverage can delay Part B. Compare providers, drugs, travel needs, and discounts. The next sections unpack choices, costs, and timing.
Important Facts
- Original Medicare includes Part A (hospital) and Part B (medical); Medicare pays ~80%, you pay ~20% unless supplemented.
- Part B averages about $185/month; higher earners may owe IRMAA based on IRS-reported income.
- Medigap keeps Original Medicare and adds predictable coverage; nationwide access, no networks, typical premiums $150–$200/month.
- Medicare Advantage replaces Original Medicare; low or $0 premiums but networks, referrals, authorizations, and per-service costs apply.
- Enroll during the 7‑month Initial Enrollment Period; delays need credible employer coverage or risk penalties and limited windows.
Understanding Original Medicare: Parts A and B
Foundation first: Original Medicare is the federal program made up of Part A (hospital) and Part B (medical/outpatient).
You enroll as an individual, even if you’re married. Part A generally costs $0 if you’ve worked enough quarters and helps cover inpatient hospital, skilled nursing, and some home health.
Part B covers doctor visits, preventive care, outpatient services, and durable medical equipment.
You’ll typically pay about $185/month for Part B, more if IRMAA applies. Medicare covers roughly 80% of approved costs; you’re responsible for the rest.
You must enroll in Parts A and B before adding other coverage. Employer coverage may delay enrollment without penalties.
Comparing Medicare Advantage and Medigap
While both routes build on Parts A and B, Medicare Advantage and Medigap work very differently.
With Advantage (Part C), you join a private plan that replaces Original Medicare, often bundling drugs and extras like dental or vision. You’ll follow the plan’s network, referrals, and prior authorizations, and costs vary by service.
With Medigap, you keep Original Medicare and add a standardized supplement (like Plan G or N) to cover gaps. You can see any Medicare-accepting provider nationwide without referrals.
Enrollment timing matters: you get guaranteed issue for six months after Part B starts. You and your spouse choose separately.
Cost Breakdown: Premiums, Co-pays, and IRMAA
Costs with Medicare fall into three buckets you should tally: fixed premiums, pay-as-you-go charges, and possible income-based surcharges.
Part A is usually $0 if you’ve paid enough into Social Security. Part B averages about $185/month, before income adjustments. If you choose Medigap, expect roughly $150–$200 more monthly (often around $150), producing an estimated $365 total for Part B plus Medigap.
With Medicare Advantage, premiums can be $0, but you’ll pay co-pays and deductibles when you use care.
IRMAA can raise Part B (and Part D, if applicable) costs for higher earners, significantly increasing monthly outlays based on your IRS-reported income.
Enrollment Timing and Eligibility Rules
After tallying premiums and potential IRMAA, you need to know when you can sign up and who must enroll. Your Initial Enrollment Period is seven months: three before, the month of, and three after your 65th birthday.
If you’ve got credible coverage from a large employer (20+ employees), you can delay Part B without penalty; otherwise, enroll to avoid lifetime surcharges. You must have Parts A and B before adding Medigap or Advantage.
- Sign up during your IEP; missing it can trigger penalties.
- Use the Special Enrollment Period when leaving large employer coverage.
- General Enrollment runs Jan 1–Mar 31 if you missed earlier windows.
Evaluating Employer Coverage vs. Medicare
Before you switch, stack your employer plan’s total annual cost against Medicare’s. Add premiums, deductible, co-pays, coinsurance, and your max out-of-pocket. Many employer plans cost around $600 monthly plus cost sharing; Medicare with Part B (~$185) and a typical supplemental plan (~$150) runs about $365, while Advantage plans can be $0 premium but pay-as-you-go.
Confirm employer size. If 20+ employees, you can delay Part B without penalty.
Compare provider networks and referral rules. Check drug coverage; Advantage often includes it, Medigap doesn’t.
Consider IRMAA if your income is high. Weigh predictable premiums versus variable costs based on expected medical use.
Tips for Choosing Plans and Leveraging Discounts
While options can feel overwhelming, you can narrow choices fast by focusing on needs, budget, and timing.
Start by listing your providers, prescriptions, and travel habits. Compare predictable-cost Medigap (G or N) to pay‑as‑you‑go Advantage plans. Check total monthly cost estimates: around $365 for Original Medicare with a supplement vs. $0 premiums on many Advantage plans but added copays.
- Verify networks, drug formularies, and annual max out‑of‑pocket; confirm Part D needs.
- Use your six‑month Medigap Open Enrollment to skip underwriting.
- Ask about household or spouse discounts with the same carrier; savings often run $20–$50 monthly.
Frequently Asked Questions
How Do Medicare and HSA Accounts Interact After Age 65?
You can’t contribute to an HSA once any part of Medicare starts, often retroactive up to six months. You can still spend existing HSA funds tax-free on qualified medical expenses, premiums for Part B, Part D, and Medicare Advantage.
Does Medicare Cover Care When Traveling Internationally?
Yes, Medicare generally doesn’t cover international care. You’ll get limited emergency coverage on some Medigap plans (G/N via foreign travel benefit) and certain Medicare Advantage plans. Consider travel insurance for broader coverage, evacuations, and high-cost emergencies abroad.
Are Dental, Vision, and Hearing Benefits Included in Medicare?
No. Original Medicare excludes routine dental, vision, and hearing. You’ll get limited medically necessary coverage only. You can add Part D for drugs and choose Medigap or a Medicare Advantage plan that includes these extras. Compare networks and costs.
How Do Prescription Drug Formularies Change Year to Year?
They change wildly: tiers shift, preferred pharmacies flip, prior authorizations explode, and copays swing. You’ll review the Annual Notice of Change, compare formularies each fall, verify your drugs, check utilization rules, and switch plans if savings scream.
Can I Use Telehealth Services Under Medicare, and What’s Covered?
Yes. You can use telehealth under Medicare. Part B covers many services: primary/specialist visits, mental health, PT/OT/ST, some preventive care, and limited home visits. You’ll owe Part B cost-sharing; Advantage plans may add benefits and different copays.
