When you spend thousands of dollars every year on health insurance, you think you’re covered when you get sick or injured. Your insurance policy should pay for the doctor, the medication, a hospital visit, or anything else that comes up. But that isn’t always the case. And if you fall victim to the gaps in your health insurance coverage, you may be on the hook for hundreds, or even thousands, of dollars. Every insurance policy has exclusions, and most people don’t discover theirs until they’re already mid-treatment or when the bill arrives in the mail. Here’s everything you need to know about hidden gaps in your health insurance and how to close those gaps to protect yourself and your wallet.
Why This Matters More Than You Think
A health insurance plan is a safety net designed to protect you when you get sick or injured. While these plans cover a wide variety of situations, there are very specific holes in the coverage where you’re responsible for some or all of the costs of care. While these coverage gaps are detailed within your policy, most people never read them.
The consequences of these gaps aren’t just financial. You could be denied care when you need it the most, or you may choose to delay the medical help you need because you fear how much it will cost. According to a recent study, 38.6% of uninsured adults put off or skipped needed care because of cost. Even if you have insurance, there is a tendency to skip or delay medical care due to financial constraints.
I encourage all of my clients to understand where the gaps are in their health insurance policies before they get sick or injured. This helps them to make informed decisions rather than scrambling for answers during an already stressful situation.
The Coverage Gaps Standard Plans Rarely Fill
Health insurance is pretty good at taking care of common situations, like catching the flu, breaking an arm, or having a baby. But there are many gaps in this coverage that often surprise people at the worst times.
Dental and Vision Care
Health insurance covers preventive medicine, illnesses and injuries throughout the body, but for some reason these policies don’t include your eyes or teeth. Instead, you’ll need to buy a separate policy for these important parts of the body. Dental and vision care policies cover the basics, like routine cleanings, fillings, and eye exams.
If you’re a senior on Medicare, some Medicare Advantage supplemental plans include dental and vision coverage.
Mental and behavioral health limits
Coverage for mental and behavioral treatment is generally limited in most healthcare plans. There are often session caps, a narrow list of in-network therapists, and limited medications covered. A plan that technically covers mental health can still leave you paying most of the bill if your provider is out of network.
For those who buy health insurance through the ACA marketplace, those plans must cover behavioral health treatment, inpatient services, and substance use disorders. However, coverage details vary by state and which plan you choose.
Fertility treatment, elective procedures, and alternative care
Fertility treatments, many elective surgeries, and therapies like acupuncture or chiropractic care are commonly excluded. While reviewing policies with clients, I’ve noticed that standard health insurance coverage typically doesn’t pay for fertility treatments, certain elective surgeries, or alternative therapies.
If your plan does cover treatments like chiropractic care or acupuncture, it usually has annual limits on the number of visits. In my experience, insurance companies exclude these treatments because they are considered optional rather than essential, regardless of your actual need.
Deductible and network surprises
Even plans that cover a service may not cover it the way you expect. Some plans require you to hit your full deductible before certain visits are paid at all, while others carve out exceptions. The details vary enough between plans that assuming “my last plan worked this way” is a mistake.
Disability and income replacement
If you get sick or injured, health insurance pays eligible medical bills. However, it doesn’t pay your mortgage, auto loan, or other bills. If an injury or illness keeps you out of work an extended period of time, your health plan won’t replace your lost income.
Approximately one in four young adults can expect to be disabled and unable to work for a year at some point before reaching retirement age. Yet, the average American lives paycheck to paycheck and can’t afford to pay an unexpected $400 expense without going into debt. While you may have excellent healthcare coverage, you need to protect your income as well with disability and life insurance.
How to Close These Gaps
While there are personal and financial risks to having gaps in your health insurance policy, you can take steps to close them. But, as I tell my clients, you don’t need to overhaul your entire insurance strategy to do so. Instead, you can make simple adjustments, buy supplemental policies, or take other actions to improve your insurance situation.
- Read your Summary of Benefits and Coverage (SBC). Most people never read these documents, yet there is a dedicated exclusions section that details what your policy won’t cover. While this is pretty boring reading, it is the fastest and most thorough way to find out what’s actually not covered before you need to find out the hard way.
- Add a rider or buy supplemental coverage. To get dental and vision coverage, you’ll need to buy a standalone policy or add a rider to your existing policy (if available). For seniors on Medicare, you may need to wait until the next Medicare window to switch Medicare Advantage policies to one that includes coverage for these treatments.
- Fund an FSA or HSA. Flexible Spending Accounts (FSAs) and Health Savings Accounts (HSAs) allow you to pay for co-pays, deductibles, and eligible medical expenses that aren’t covered by insurance with pre-tax money. To contribute to an HSA, you must be enrolled in an HSA-eligible plan. HSAs offer triple-tax benefits with tax deductions for contributions, tax-deferred growth, and tax-free withdrawals for eligible expenses.
- Look into short-term or supplemental disability insurance. While you may receive disability income through work or government benefits, these benefits rarely cover your entire salary and often have substantial exclusions. For this reason, I recommend clients buy an individual disability policy to cover the income gap that health insurance was never designed to fill.
- Call your insurer before a scheduled procedure. Ask directly whether the specific service, provider, and facility are in-network and covered. Finding low-cost providers may enable your insurance to cover more of the procedure and reduce your out-of-pocket cost. Do not wait until after the procedure is complete because that limits your options and negotiating leverage.
- Consider generic medicines. Generic prescriptions are typically a fraction of the cost of name-brand medicines. In some cases, they are free or under $10. If you’re taking the medicine regularly, I recommend subscribing to mail-order delivery with a 90-day supply to save even more. Prescription drug discount services that can reduce drug costs even further, and many are free or charge a small fee.
- Revisit your plan every renewal period. During open enrollment, review all plan options and take into consideration current ailments, ongoing prescriptions and treatments, and upcoming procedures. Carefully review policies because exclusions and network rules can change year to year even when premiums look similar.
Bottom Line
Coverage gaps aren’t a flaw in health insurance policies. They are planned exclusions of certain procedures, medicines, and treatments to reduce insurance company expenses and the premiums they charge. Every policy draws a line somewhere between what’s covered and what isn’t, so it is critical that you review policy options to determine if those exclusions affect your known health concerns and ongoing treatments and prescriptions. If you don’t take the time to review these documents, you could be in store for a surprise denial of treatment or a substantially larger piece of that medical bill.
