Even if you retire before age 65, Medicare becomes the foundation of healthcare coverage at age 65. It’s not perfect—it has gaps and limitations—but it’s what we have, and we need to understand it.
I view Medicare as part of God’s common grace provision for our society. It ensures that seniors have access to basic healthcare regardless of their financial situation. Is it a perfect system? No, absolutely not; improvements and reforms are needed. But it’s available to virtually everyone who reaches age 65 and has worked reasonably well for many decades.
Let’s break down the basics.
Medicare Part A: hospital insurance
What it covers:
- Inpatient hospital stays
- Skilled nursing facility care (limited—only after a 3-day hospital stay, and only for up to 100 days)
- Hospice care
- Some home health care
What it costs (2026):
- $0 monthly premium for most people (if you or your spouse paid Medicare taxes for at least 10 years)
- $285 monthly premium if you have 30-39 quarters of coverage
- $518 monthly premium if you have fewer than 30 quarters
Important limitations:
- Does NOT cover long-term care in nursing homes
- Skilled nursing coverage is very limited
- Hospital deductible is $1,676 per benefit period in 2026
- After 60 days in hospital: $419/day co-insurance (days 61-90)
- After 90 days: $838/day for lifetime reserve days
Most people qualify for premium-free Part A and should enroll when they’re eligible at age 65, even if they’re still working and have employer coverage.
Medicare Part B: medical insurance
What it covers:
- Doctor visits
- Outpatient care
- Preventive services
- Medical equipment (wheelchairs, walkers, etc.)
- Some home health care
- Many diagnostic tests
What it costs (in 2026):
- Standard premium: $185.00/month (deducted from Social Security if receiving benefits)
- Annual deductible: $257
- Then you typically pay 20% of Medicare-approved amounts
IRMAA (Income-Related Monthly Adjustment Amount):
This is critical to understand. If your income (Modified Adjusted Gross Income from 2 years prior) exceeds certain thresholds, you pay MORE for Part B:
2026 IRMAA Brackets (Individual / Married Filing Jointly):
- ≤212,000: Standard $185.00/month
- 133,000 / 266,000: $259.00/month
- 167,000 / 334,000: $369.90/month
- 200,000 / 400,000: $480.80/month
- 500,000 / 750,000: $591.70/month
- 750,000: $628.90/month
Notice how this works: IRMAA is based on your tax return from two years ago. When you enroll in Medicare in 2026, they look at your 2024 tax return. This creates IRMAA-mitigating planning opportunities—such as Roth conversions, income timing, and the use of Donor-Advised Funds for giving—that can save thousands on Medicare premiums.
Part B Enrollment:
Unlike Part A, Part B requires active enrollment and has penalties if you delay without creditable coverage:
- Initial Enrollment Period (IEP): 7 months (3 months before your 65th birthday month, your birthday month, and 3 months after)
- Late enrollment penalty: 10% increase for each 12-month period you were eligible but didn’t enroll (permanent penalty)
- Special Enrollment Period: If you (or your spouse) are working with employer coverage of 20+ employees, you can delay Part B without penalty
When my wife turned 65, I was still working with employer coverage. We enrolled her in Part A (no cost, no downside), but delayed Part B because my employer plan was primary coverage. When I retired two years later, we both enrolled in Part B through the Special Enrollment Period with no penalty.
Medicare Part D: prescription drug coverage
Part D is provided by private insurance companies approved by Medicare. It’s optional but highly recommended, and there’s a penalty for late enrollment.
What it costs (2026):
- Average premium: $40-60/month (varies by plan and location)
- Annual deductible: Up to $590 (many plans have $0 deductible)
- IRMAA surcharges apply (same income brackets as Part B, adding $13.70 to $86.90/month)
The “donut hole” (coverage gap):
After you and your plan spend $5,030 in 2026, you enter the coverage gap where you pay 25% of drug costs until you reach $8,000 in out-of-pocket spending. Then catastrophic coverage kicks in (5% or small co-pays).
Late enrollment penalty:
1% of the national base beneficiary premium ($34.70 in 2026) for each month you were eligible but didn’t enroll. This penalty is permanent.
My recommendation: Enroll in Part D when you first become eligible, even if you don’t take many prescriptions now. The penalty compounds over time, and healthcare needs typically increase with age.
I’ll be honest—Part D is confusing. Every plan has different formularies (lists of covered drugs), different costs for different tiers, and different pharmacy networks. My wife and I spend an hour each fall during open enrollment (October 15-December 7) using Medicare.gov’s plan finder tool to see if our current plans are still the best options.
Original Medicare vs. Medicare Advantage
Once you understand Parts A, B, and D, you face a critical decision: Original Medicare with supplemental coverage, or Medicare Advantage.
This isn’t just about monthly premiums. It’s about tradeoffs between flexibility, predictability, and cost. Let me walk you through both options.
Path #1: Original Medicare + Medigap + Part D
This is the traditional approach, and it’s what my wife and I chose.
How it works:
- You have Medicare Parts A & B (Original Medicare)
- You purchase a Medigap (Medicare Supplement) policy from a private insurer to cover the gaps
- You purchase a standalone Part D plan for prescriptions
The Medigap plans:
There are 10 standardized Medigap plans (A, B, C, D, F, G, K, L, M, N). The benefits are identical for each plan letter, regardless of which insurance company sells it—Plan G from Blue Cross covers exactly the same things as Plan G from Humana. The only differences are price and customer service.
Most popular plan in 2026: Plan G
Plan F used to be the most popular, but it’s no longer available to new Medicare beneficiaries (those who became eligible after January 1, 2020). Plan G is now the gold standard:
- Covers: Part B excess charges, Part A coinsurance and hospital costs, first 3 pints of blood, Part A hospice coinsurance, skilled nursing facility coinsurance, Part A deductible, foreign travel emergency
- Doesn’t cover: Part B deductible ($257 in 2026)
Typical Plan G costs (2026):
- Age 65: $125-180/month
- Age 75: $155-220/month
- Age 85: $190-270/month
(Rates vary significantly by state, zip code, gender, tobacco use, and whether it’s “attained age,” “issue age,” or “community-rated” pricing.)
Other coverage needed:
- Part D prescription plan: $40-60/month average
- Dental insurance (optional): $25-50/month
- Vision insurance (optional): $15-30/month
Total monthly cost example for a couple (both age 70):
- Part B premium: $185 x 2 = $370
- Medigap Plan G: $175 x 2 = $350
- Part D: $50 x 2 = $100
- Total: $820/month or $9,840/year
(This doesn’t include deductibles, co-pays for prescriptions, or dental/vision care)
Advantages:
- Complete freedom: See any doctor or specialist who accepts Medicare (about 93% of doctors nationwide)
- No networks: No need for referrals, no in-network vs. out-of-network concerns
- Predictable costs: After premiums and Part B deductible, most costs are covered
- Travel flexibility: Coverage works anywhere in the U.S.
- Stability: Medigap plans rarely change benefits
Disadvantages:
- Higher monthly premiums: You’re paying for that flexibility and predictability
- Three separate plans: Part B, Medigap, and Part D require coordination
- No extras: Doesn’t include dental, vision, hearing, or gym memberships
- Medigap underwriting: If you don’t enroll during your Medigap Open Enrollment Period (6 months starting when you turn 65 and enroll in Part B), you may be denied coverage or charged higher rates due to health conditions
Path #2: Medicare Advantage (Part C)
Medicare Advantage plans are an all-in-one alternative offered by private insurance companies.
How it works:
Medicare pays the insurance company a set amount to manage your care. The company must provide at least the same coverage as Original Medicare (Parts A & B), but can add extra benefits and set its own rules about networks, referrals, and cost-sharing.
Types of Medicare Advantage plans:
- HMO (Health Maintenance Organization): Must use network doctors, need referrals for specialists
- PPO (Preferred Provider Organization): Can see out-of-network doctors at a higher cost, usually no referrals needed
- PFFS (Private Fee-for-Service): Can see any provider who accepts the plan’s terms
- SNP (Special Needs Plan): For specific diseases or circumstances
What’s typically included:
- Parts A, B, and D (medical and prescription coverage)
- Often: Dental, vision, hearing
- Sometimes: Gym memberships, over-the-counter allowances, meal delivery
- Maximum out-of-pocket limit (federal cap is $8,850 in 2026 for in-network, though plans can set lower limits)
Typical costs (2026):
- Plan premium: $0-75/month (many plans have a $0 premium)
- Still pay Part B premium: $185/month
- Deductibles: Varies by plan (500 typical)
- Co-pays: $10-50 per doctor visit, $350-500 per hospital stay
- Maximum out-of-pocket: $3,000-8,850/year
Total monthly cost example for a couple (both age 70):
- Part B premium: $185 x 2 = $370
- Plan premium: $25 x 2 = $50
- Total: $420/month or $5,040/year
(Plus co-pays, co-insurance, and potential out-of-pocket costs up to the annual maximum)
Advantages:
- Lower monthly premiums: Sometimes a $0 plan premium (though you still pay Part B)
- All-in-one: Medical, hospital, and prescriptions in one plan
- Extra benefits: Dental, vision, and hearing are often included
- Out-of-pocket maximum: Protects against catastrophic costs
- Predictable co-pays: A $20 doctor visit is easier to budget than 20% of unknown costs
Disadvantages:
- Networks: Must use in-network providers (or pay much more out-of-network)
- Referrals: Some plans require referrals to see specialists
- Pre-authorization: May need approval before procedures
- Annual changes: Plans can change networks, costs, and benefits each year
- Travel limitations: Coverage may be limited outside your service area
- Hard to switch: If you try Medicare Advantage and want to switch back to Original Medicare + Medigap later, you may be denied Medigap coverage due to health conditions
Medicare Health Insurance Options (Updated 2026) is a more comprehensive guide to Medicare, updated from its original 2016 publication. It draws on nearly ten years of my actual Medicare experience to explain the four parts of Medicare (Part A hospital coverage, Part B medical insurance at $202.90/month standard premium in 2026, Part C Medicare Advantage plans, and Part D prescription drug coverage), the critical decision between Original Medicare plus Medigap versus Medicare Advantage, and the income-related surcharges (IRMAA) that can add $81.20 to $487/month per person to Part B premiums for those with incomes exceeding $109,000 individual/$218,000 joint based on tax returns from two years prior. The article provides detailed 2026 cost data (Part A deductible $1,736, Part B deductible $283, typical Medigap Plan G premiums $125-$260/month depending on age), explains enrollment periods (Initial Enrollment Period starting 3 months before your 65th birthday, Special Enrollment Period for those with employer coverage from companies with 20+ employees, and Annual Enrollment Period October 15-December 7), and emphasizes critical timing decisions to avoid permanent late-enrollment penalties (10% per year for Part B, compounding annually for Part D). I discuss our personal experience choosing Original Medicare with Plan F Medigap coverage and successfully navigating the Special Enrollment Period when transitioning from employer coverage. I conclude that while Medicare is complex, the system is navigable with proper planning and annual review, making healthcare cost management an essential component of faithful retirement stewardship.
Medicare Commercials – Be Wise as Serpents and Innocent as Doves (Updated 2025) deconstructs the misleading Medicare Advantage television commercials that flood the airwaves every October-December Annual Enrollment Period by examining their specific claims and revealing what they conveniently omit—including that the “give-back benefit” of up to $202.90/month (2026 Part B premium) isn’t free money but rather a partial rebate of premiums you’re already paying the government, that “$0 premium” Advantage plans still carry out-of-pocket maximums up to $9,250 per person annually ($18,500 for a couple), that “free” dental/vision/hearing/transportation benefits come with network restrictions and prior authorization requirements that Original Medicare + Medigap don’t impose, and that the urgent “today is one of the only days” language creates artificial scarcity when the enrollment period actually runs 61 consecutive days from October 15-December 7. The article emphasizes the critical trap the commercials never mention: while Medicare Advantage plans are excellent for healthy people with minimal medical needs who don’t travel and are comfortable with networks, switching from Advantage to Medigap after developing serious health conditions (cancer, heart disease, COPD, diabetes) becomes extremely difficult or impossible because insurance companies can deny coverage or charge prohibitively high premiums based on pre-existing conditions except during the one-time six-month Medigap Open Enrollment Period when first enrolling in Part B. Drawing on Matthew 10:16’s call to be “wise as serpents and innocent as doves,” after nearly nine years on Medicare with a Medigap plan—I urge readers to use official government resources (Medicare.gov Plan Compare, state SHIP programs offering free unbiased counseling) rather than calling the 1-800 numbers in commercials that connect to commissioned insurance brokers, to understand that Medicare Advantage plans are for-profit insurance products (not government programs) designed to make money when you use less care, and to make Medicare decisions based on realistic assessment of long-term health trajectory and trade-offs (provider freedom and predictable costs versus lower premiums and bundled benefits) rather than FOMO manufactured by marketing departments targeting cognitively vulnerable seniors.
Medicare Commercials: The Hilarious But Confusing Comeback Tour You Didn’t Ask For (Updated 2026) is a lighthearted yet substantive consumer-protection article, updated for 2026 from its original 2023 publication, uses the characters from actual Medicare Advantage television commercials—particularly the perpetually skeptical “Martha” who adamantly refuses to call the 1-800 number and “Karen” who just wants the commercials to stop—to illustrate the manipulative FOMO (fear of missing out) tactics employed by Medicare Advantage marketing campaigns that promise “free” benefits, “zero-dollar premiums,” and “extra coverage” while conveniently omitting critical information like the $9,250 per person annual out-of-pocket maximum in 2026, network restrictions that limit which doctors you can see, prior authorization requirements that delay care, and most importantly the trap that makes switching from Medicare Advantage to Medigap extremely difficult or impossible if you develop serious health conditions (cancer, heart disease, COPD, diabetes) due to medical underwriting that allows insurance companies to deny coverage or charge prohibitively high premiums for pre-existing conditions. The article provides a detailed comparison showing that while Medicare Advantage plans with $0 premiums beyond the required Part B payment ($202.90/month in 2026) can save healthy people thousands annually, Original Medicare plus Medigap costs $905-1,265/month for a couple but provides complete provider freedom nationwide, predictable costs with minimal out-of-pocket expenses, and no network restrictions or prior authorization hassles—making it the better choice for those who travel, have chronic conditions, or value flexibility over lower monthly premiums.
How to choose
I can’t tell you which path is right for you. Here’s an article that goes into detail on this all-important decision.
Choosing a Medicare Plan (Updated 2026), explains in detail the fundamental choice every Medicare beneficiary must make between Original Medicare plus Medigap supplemental insurance (which offers complete provider freedom nationwide, predictable costs, and comprehensive coverage but costs $905-1,265/month for a couple including Part B premiums, Medigap Plan G at $350-520/month for two, Part D prescriptions, and vision/dental) versus Medicare Advantage plans (which bundle Parts A, B, and usually D with often-included dental, vision, and fitness benefits, charge $0-80/month premiums beyond the required Part B premium of $405.80/month for a couple, but impose network restrictions, require prior authorization for some procedures, and carry out-of-pocket maximums up to $9,250 per person annually in 2026). The article emphasizes the critical but often-overlooked trap: while you can switch from Medigap to Medicare Advantage relatively easily, switching back from Advantage to Medigap after developing serious health conditions (cancer, COPD, diabetes, heart disease, stroke) is extremely difficult or impossible due to medical underwriting—insurance companies can deny coverage or charge prohibitively high premiums for pre-existing conditions except during the six-month Medigap Open Enrollment Period that begins when you first enroll in Part B, making that initial decision crucial and potentially irreversible. I stress that while neither choice is inherently wrong—healthy people who don’t travel can save thousands with $0-premium Advantage plans—the decision must be made intentionally based on individual circumstances, risk tolerance, provider flexibility preferences, and realistic assessment of future health trajectory, applying the “regret minimization” framework of imagining yourself 10-20 years out with serious health conditions and asking whether you’d regret having chosen network restrictions and potential difficulty switching to comprehensive coverage when you most need it.
Here is a “quickie” decision framework that you may find helpful:
Choose Original Medicare + Medigap if:
- You want complete freedom to see any doctor without referrals or network restrictions
- You value predictable costs over lower monthly premiums
- You travel frequently or spend time in multiple states
- You have ongoing health issues requiring access to specialists
- You prefer a “set it and forget it” approach (fewer annual changes)
- You can afford the higher monthly premiums
Choose Medicare Advantage if:
- You want the lowest possible monthly premiums
- You’re comfortable with network restrictions and referrals
- You stay primarily in one geographic area
- You want extra benefits (dental, vision, gym) without separate policies
- You want an annual out-of-pocket maximum for budget protection
- You’re willing to reevaluate your plan annually during open enrollment
- You’re healthy and don’t anticipate frequent specialist visits
The “right” answer depends on your health, finances, preferences, and peace of mind. There’s no one-size-fits-all solution.
