The Biggest Health Insurance Mistakes People Make Before Age 65

People are constantly searching for health insurance help and often don’t realize the mistakes they’re making until it’s too late. After working with hundreds of clients over nearly a decade, I’ve seen the same preventable errors repeated over and over. The good news? These mistakes are entirely avoidable if you know what to look for.

In this guide, I’ll walk you through the five biggest health insurance mistakes I see people make before reaching retirement age, and more importantly, how to avoid them.

1. Choosing Plans Based Only on Premium

One of the most common mistakes I see is people selecting a health insurance plan simply because it has the lowest monthly premium. While cost matters, this approach often costs you far more in the long run.

The Real Cost of Cheap Premiums

When you focus solely on premium prices, you often overlook:

• Higher deductibles: A plan with a $100/month lower premium might have a $5,000 higher deductible
• Narrower networks: Cheaper plans sometimes limit your choice of doctors and hospitals
• Higher out-of-pocket maximums: Your total exposure to costs could be significantly higher
• Lower coverage levels: You might face higher copayments or coinsurance percentages

What You Should Do Instead

Look at the total cost of ownership, not just the monthly premium. Calculate:

• Your estimated monthly premium
• Your likely deductible based on your health needs
• Average copayments for services you use regularly
• The out-of-pocket maximum (your maximum total exposure in a year)

A plan with a slightly higher premium but lower deductible might actually save you thousands if you see doctors regularly or have any chronic conditions.

2. Ignoring Provider Networks

Many people sign up for a plan without checking if their preferred doctors, specialists, and hospitals are included in the network. This is a critical oversight that can leave you scrambling once you’ve already committed to the plan.

Why Networks Matter

Health insurance plans define which doctors and hospitals are “in-network” versus “out-of-network.” Here’s the difference:

• In-network providers: Negotiated rates, lower costs for you, counts toward your deductible
• Out-of-network providers: No negotiated rates, much higher out-of-pocket costs, may not count toward your deductible

Using an out-of-network provider can easily cost you 2-3 times more than an in-network provider for the same service.

What You Should Do Instead

Before enrolling in any plan:

1. Make a list of your current doctors and specialists
2. Check the insurance company’s provider directory online
3. Call your doctor’s office directly to confirm they accept that plan
4. Verify that your preferred hospital is in-network
5. If you’re considering changing doctors, confirm the new doctor is in-network before making the switch

Don’t assume that just because you’ve seen a doctor before that they’ll be in your new plan’s network. Networks change, and doctors move.

3. Not Understanding Deductibles

Deductibles are one of the most misunderstood aspects of health insurance, and confusion about them leads to major budget surprises. Many people think they have insurance coverage immediately, but that’s not how deductibles work.

How Deductibles Work

Your deductible is the amount of money you have to pay out of your own pocket for healthcare services before your insurance company starts sharing the cost with you.

Here’s an example:

• You have a plan with a $2,000 individual deductible
• You go to the doctor and pay $150 for the visit—this counts toward your deductible
• You have lab work done for $300—this also counts toward your deductible
• You’re now at $450 of your $2,000 deductible
• Once you reach $2,000, your insurance starts to help pay for covered services

Key point: Preventive services (like annual checkups, cancer screenings, and vaccinations) are typically covered at 100% even before you meet your deductible. Don’t skip these!

What You Should Do Instead

• Understand your plan’s deductible before you enroll
• Budget for the deductible as part of your healthcare expenses
• If you anticipate needing medical care, choose a plan with a deductible you can actually afford to pay
• Take advantage of preventive care that’s covered at no cost—you’re literally throwing money away if you skip it

4. Missing Enrollment Windows

One of the worst mistakes you can make is letting health insurance enrollment deadlines pass without taking action. Missing these windows can leave you uninsured, facing penalties, or locked into poor coverage for an entire year.

The Different Enrollment Periods

• Open Enrollment: Typically November 15 - December 15 each year. This is when most people can enroll in or change plans.
• Special Enrollment Periods: If you have a qualifying life event (got married, had a baby, lost job-based coverage), you get a limited window to enroll.
• Medicare Enrollment: Turning 65? Medicare enrollment happens around your birthday month.

Why Missing These Windows Is Expensive

• No coverage: If you miss open enrollment and don’t have a qualifying event, you’ll be uninsured until next year’s enrollment period
• Penalties: The IRS may charge penalties if you don’t have coverage
• Limited options: You can’t change plans mid-year without a qualifying event

What You Should Do Instead

• Mark these dates on your calendar well in advance
• Don’t wait until the last day—these periods get busy
• If you think you might have a qualifying life event coming up, understand what qualifies and how to document it
• Set phone reminders for yourself 2-3 weeks before any deadline

5. Waiting Until They’re Sick to Shop

This is perhaps the most expensive mistake: waiting until you have a health problem before shopping for new insurance. While open enrollment is technically open to everyone, waiting until you’re facing medical issues can result in significantly higher premiums or coverage limitations.

Pre-Existing Condition Protections (and Their Limits)

The Affordable Care Act (ACA) prohibits insurance companies from denying coverage or charging more based on pre-existing conditions. However, this protection has important limitations:

• It applies to plans purchased during open enrollment, not outside these windows
• If you don’t have continuous coverage, you may still face waiting periods or exclusions
• The protection is for eligibility and premium, not for what the plan covers

More importantly, if you wait until you’re sick, you’re evaluating plans while in crisis mode rather than logically comparing options.

What You Should Do Instead

• Shop for insurance during open enrollment every year, even if you think your current plan is fine
• During open enrollment, proactively evaluate whether your current plan still meets your needs
• If you’re anticipating a health issue, get covered during open enrollment before the problem develops
• Review your plan annually and plan for changes you know are coming (like starting a new medication or scheduling planned surgery)

The Bottom Line

Choosing health insurance doesn’t have to be overwhelming. By avoiding these five common mistakes, you’ll ensure that you have coverage that actually meets your needs at a price you can afford.

The best approach is to think holistically about your health insurance coverage:

• Look beyond the premium to total cost
• Verify your providers are included
• Understand what your deductible means
• Mark enrollment deadlines on your calendar
• Shop proactively, not reactively
