Health Insurance - Navigating the Complex World of Medical Coverage

Health insurance is likely the most confusing and most significant kind of insurance you’ll ever have to contend with. Between HMOs PPOs, HSAs and all these acronyms it would seem like you require a medical degree just to comprehend your coverage. Let me simplify it all for you in a manner that actually makes sense.

The Different Types of Health Insurance Plans

HMO (Health Maintenance Organization) plans are the health insurance equivalent of strict parents. You must select a primary care doctor who serves as your gatekeeper. Need to visit a specialist? You must get a referral first. The plus is that these plans typically have lower premiums and copays. The minus is less flexibility.

PPO (Preferred Provider Organization) plans are more liberating. You can visit any doctor or specialist without a referral but staying in the network saves money. These plans cost more but many individuals like having the flexibility.

EPO (Exclusive Provider Organization) plans are a compromise. You don’t require referrals but you have to remain within the network unless it’s an emergency. Go out of network and you’re paying full price yourself.

POS (Point of Service) plans are a mix of HMO and PPO plans. You require a primary care physician and referrals but you can go out of network if you pay more.

HDHP (High Deductible Health Plan) with HSA is getting very popular. HDHPs come with big deductibles (typically $1,500-$3,000 for an individual) but low premiums. The huge benefit is they’re accompanied by a Health Savings Account where you save tax-free money for medical bills.

Getting to Know Your Health Insurance Costs

The thing about health insurance is that there are more costs involved than just your premium every month. You’ve got to consider the big picture.

Suppose you’re comparing two policies. Policy A costs $200 per month with a $500 deductible. Policy B costs $350 per month with a $100 deductible. Which is better?

Well it just depends on how much you use healthcare. If you hardly ever see the doctor Plan A could end up costing you less in the year. But if you have ongoing prescriptions or doctor’s visits Plan B may end up costing you less even though the premium is higher.

I learned the hard way when I opted for the cheapest plan option. It seemed like a smart thing to do at the time. Then I required physical therapy due to a sports injury and paid significantly more out of pocket than I would have with a somewhat higher-cost plan. Do the math according to your actual health care needs rather than the price tag.

What Does Health Insurance Actually Cover

The majority of health insurance policies must provide ten basic health benefits due to the Affordable Care Act. They are:

But it gets complicated here. Just because something is “covered” doesn’t necessarily mean it’s free. You’ll still have copays, coinsurance and your deductible to contend with.

Also not everything is covered. Cosmetic procedures, most alternative treatments, and experimental procedures typically aren’t covered. Always read the fine print or call your insurance company before having a procedure done.

The Open Enrollment Period and Special Enrollment

You can’t simply purchase health insurance on whim. There is normally an open enrollment time of once a year (normally November to December) during which you can enroll in or modify your health insurance policy.

Miss that and you’re locked into what you have for the remainder of the year. Unless you are eligible for a special enrollment period which occurs when you experience certain life events such as:

These situations provide you with a limited timeframe (typically 60 days) to join a new plan outside of the regular enrollment period.

How to Select the Right Health Insurance Policy

Selecting a health insurance policy is not about getting the lowest-cost plan. You must think about your true healthcare needs.

Begin by examining your health history. Do you have regular medications? Ongoing illnesses? Regular specialists? If so you likely would prefer a plan with a lower deductible and more coverage even if it costs more.

Next examine the network. Ensure that your present physicians and the hospitals you want are in-network. Having to change doctors due to insurance is annoying and sometimes medically challenging.

Check out the coverage of prescription drugs. If you have high-cost medications this can save you a ton of money on your out-of-pocket expenses. Some plans offer more pharmacy benefits than others.

Take out an HSA if you qualify. These accounts allow you to contribute pre-tax dollars towards medical bills and the funds carry over from year to year unlike FSAs. Its essentially a healthcare-related retirement account.

Handling Medical Bills and Insurance Claims

Even with insurance, medical bills can be baffling and even error-ridden. Here’s what you should know about handling them.

First always request an itemized bill. You’d be surprised how frequently there are mistakes or billing for services you didn’t have. I once picked up on an $800 charge for a drug I never received just by going over the itemized statement.

Second understand the Explanation of Benefits (EOB) you receive from your insurance company. This is not a bill - it’s a statement explaining what was billed, what the insurance paid and what you pay. Don’t freak out when you receive it.

If you receive a large medical bill that you cannot pay don’t overlook it. Contact the billing department and ask for payment plans or financial aid. A lot of hospitals offer things that can lower or waive bills depending on your income.

Also don’t hesitate to negotiate. Medical billing is more negotiable than you might believe. Sometimes you can receive huge discounts just by asking particularly if you are paying in cash.

Medicare and Medicaid - Government Health Insurance Programs

Medicare is national health insurance for individuals 65 and older as well as some younger individuals with disabilities. It comes in several parts:

Medicaid is a federal and state program for individuals with low income. It differs from state to state but typically covers low-income families, pregnant women and the disabled.

They’re lifesavers for millions of Americans but they can be complicated. If you or a family member are eligible take time to learn the choices and sign up for the coverage that is right for you.

The Future of Health Insurance

Healthcare and insurance are constantly changing. Telemedicine has taken off in popularity particularly after 2020. Most insurance policies now cover virtual doctor consultations which is really handy.

There is also an increasing trend towards value-based care where insurance companies and healthcare organizations more emphasis on keeping you healthy than treating you when you’re unwell. This may translate to increased coverage for preventive care and wellness programs.

High-deductible plans combined with HSAs are increasingly popular as employers seek cost-control strategies while providing employees with more control over healthcare expenses.

No matter what changes are ahead, understanding your health insurance choices and selecting the appropriate coverage is one of the most significant financial decisions you’ll ever make. Your health and your pocketbook are at stake.
