The Power of Supplemental Health Insurance: How it Can Fill the Gaps

What is Supplemental Health Insurance?

Supplemental health insurance is designed to supplement and fill the gaps in primary health insurance plans. You can purchase these policies in addition to your primary health plan to help pay for out-of-pocket costs or medical services that your existing policy does not cover.

But remember, though many supplemental health insurance are affordable and offer great terms, they’re not intended to stand alone as your only healthcare coverage as they typically do not cover medical treatments, such as surgeries. 

Filling in the Gaps of Traditional Health Insurance

Supplemental health insurance plans come in various forms. Still, they all offer financial support by either covering your out-of-pocket costs like deductibles and copayments or helping you pay for specific care that your primary policy does not cover. While some primary health insurance plans are relatively comprehensive, you may still have to pay for some treatment costs yourself, which could quickly add up and cause financial strain. 

So, if you have a family history of diseases, such as cancer, stroke, heart disease, etc., or want extra financial protection in the event of unexpected injuries, consider looking into supplemental health insurance to fill the gaps in your existing health plan.

How Does Supplemental Health Insurance Work?

Some supplemental health insurance policies provide a lump sum of money you can use for specific healthcare services like cancer treatments, while some cover expenses not paid for by your primary health insurance, such as deductibles and copays. Every supplemental health insurance differs, so coverage and eligibility requirements can vary. 


Eligibility requirements for supplemental health plans can differ depending on the insurer and the type of plan you choose. For example, if you’re interested in Medicare Supplement Insurance Plans or Medigap plans, you must be 65 or older and be enrolled in Original Medicare.

However, if your employer offers group supplement health plans as an employee benefit, you’re typically eligible for coverage as long as you’re a full-time employee. Check with the provider for details on eligibility requirements if you’re purchasing supplemental health insurance for yourself or your household.   


The specific coverage will depend on the type of supplemental health insurance you choose. But generally, supplemental health insurance plans can cover a range of out-of-pocket costs like deductibles, copayments, coinsurance, dental and vision care, or specific illnesses.

Types of Supplemental Health Insurance

You can find various types of supplemental health insurance policies on the market, but the following are some of the most common ones available. 

Critical Illness

Critical illness provides additional coverage when the beneficiary experiences a life changing event, like a heart attack, stroke, or critical illness diagnosis. Because these types of life threatening illnesses can incur costly medical expenses, having a critical illness supplemental health insurance could potentially save you thousands of dollars when your primary health insurance falls short. 

Besides heart attacks and stroke, critical illness insurance may also cover the following:

  • Organ transplants
  • Cancer
  • Coronary bypass
  • Renal failure 
  • Paralysis
  • Loss of arms or legs
  • Traumatic head injury 
  • Multiple sclerosis
  • Parkinson’s disease
  • Alzheimer’s disease


Disability insurance provides a benefit if you become either partially or totally disabled due to an illness or injury. The government and many employers offer disability insurance as a supplemental benefit to help beneficiaries pay their bills if they’re too sick or injured to work.

This supplemental health insurance can be especially helpful for those who depend on their job for living expenses or are the family’s breadwinner. The type of injuries or illnesses covered by disability insurance may include: 

  • Back problems
  • Arthritis
  • Injuries from an accident
  • Childbirth
  • Musculoskeletal disorders
  • Nervous system disorders
  • Injuries from an accident
  • Mental health problems


Hospitalization insurance, also known as hospital insurance or hospital indemnity, is a supplemental insurance plan that helps cover the unexpected costs associated with hospital stays. You can use the payout from this supplemental health insurance for anything.

For example, deductibles, transportation costs, medications, groceries, childcare, or home care expenses. Consider looking into hospitalization insurance if you suffer from a chronic condition like diabetes that could lead to hospitalization or an upcoming surgery requiring an extended hospital stay. 

While coverage may vary depending on the insurance provider, hospitalization insurance typically provides a payout when you require the following: 

  • Hospitalization 
  • Critical care
  • Intensive care
  • Emergency room visits
  • Outpatient surgery 
  • Ambulance services


Paying for cancer treatments out-of-pocket can put a dent in your wallet. And even with the help of your primary health insurance, costs can still be high. Thankfully, supplemental cancer insurance helps cover expenses your primary health insurance may not cover.

With the payout from this supplemental insurance, you can pay for medical expenses associated with cancer treatment and everyday costs such as mortgage payments, electricity bills, or transportation. Supplemental cancer insurance can help you shoulder the costs of common medical procedures and treatments, including:

  • Radiation therapy 
  • Chemotherapy 
  • Immunotherapy or experimental chemotherapy 
  • Stem cell and bone marrow transplant 
  • Surgery 
  • Anesthesia
  • Hormonal therapy 


Accidents happen when you least expect them, and the medical bills can quickly add up if you’re not protected. By purchasing supplemental accident insurance in addition to your primary policy, you would not have to worry about incurring hefty medical debt since you’ll receive cash benefits when a covered accidental injury occurs.

While most people can benefit from supplemental accident insurance, it may be especially useful for those with a limited budget for unexpected medical expenses or who live an active lifestyle with a higher risk of injury.

Accident insurance may cover the following: 

  • Burns
  • Dislocations
  • Fractures
  • Broken limb
  • Loss of a limb
  • Dental or eye injuries
  • Concussions
  • Lacerations
  • Emergency room care 
  • Ambulance services
  • Physical therapy 

Long Term Care

Traditional health insurance typically only pays for doctor and hospital bills and would not cover long term care services such as assisted living and adult daycare. However, long term care is expensive and could cause significant financial strain if you pay for it out-of-pocket. It’s estimated that 7 out of 10 Americans over 65 will need long-term care, and 20% will need it for over five years. 

Unless you’ve built a large enough nest egg to cover the expenses for a nursing home, assisted living facility, in home care, etc., consider looking into long term care insurance. Long term care insurance typically covers all or part of long term care services for those with a chronic condition or disability. Each state and insurance company has its own eligibility requirements and guidelines. Check with your insurance provider to see if you’re eligible. 

Most long-term care insurance policies cover the following services: 

  • Home health care
  • Adult daycare
  • Personal care
  • Homemaker services
  • Hospice services 
  • Respite care 

Dental and Vision

Because traditional health insurance coverage typically does not provide benefits for routine dental and vision care services, purchasing supplemental insurance that covers these services can save you thousands of dollars in medical expenses.

Each dental and vision supplemental plan offers a different level of coverage, ranging from routine eye exams to insurance for root canals, crowns, and more. So, if you anticipate requiring extensive vision or dental procedures, it may be time to look into supplemental benefits to cover these expenses. Dental and vision supplemental health insurance may cover the following procedures and services: 

  • Dental
    • Orthodontics
    • Teeth whitening
    • Dental implants
    • Fillings 
    • Crowns 
    • Root canals
    • Dentures and bridges
    • Routine exams, cleanings, and X-rays
  • Vision
    • Eye exams
    • Prescription glasses or contact lenses
    • Lens coating and enhancements 
    • Laser vision correction surgery

Should You Get Supplemental Health Insurance?

Supplemental health insurance can benefit those needing more coverage for medical expenses beyond what their primary health insurance offers. So, if you’re self-employed or have limited insurance coverage through your employer, you may want to consider purchasing a supplemental plan to lower your out-of-pocket costs. But before deciding, consider the following pros and cons to determine if the additional cost is worth it.

  • Enhanced coverage
  • Financial protection
  • Customizable options
  • Cash benefits
  • Access to additional services
  • Additional cost
  • Limited coverage scope
  • Policy restrictions
  • Overlapping coverage
  • Limited availability


  • Enhanced Coverage: Supplement health insurance can fill in gaps such as deductibles, copays, etc., and lower the out-of-pocket expenses your primary policy may not fully cover.
  • Financial Protection: Supplement health insurance offer benefits for specific health events like cancer and helps alleviate your financial burden associated with hospital stays and related medical expenses. 
  • Customizable Options: Most supplemental health insurance policies allow you to customize your plan by choosing the coverage that best suits your needs. 
  • Cash Benefits: Some supplemental plans, like hospitalization insurance, provide cash benefits that are paid directly to the beneficiary, allowing them to use the funds to cover various expenses, such as accommodation, groceries, and transportation. 
  • Access to Additional Services: Some plans may also offer additional perks, such as telemedicine, prescription discounts, etc., to help improve your overall health and well-being. 


  • Additional Cost: Additional coverage typically means additional costs. If your primary health insurance plan is already expensive, adding a supplemental plan could increase your financial burden. 
  • Limited Coverage Scope: Supplemental health insurance generally only covers specific conditions or events, like critical illnesses or hospitalizations, and may not provide comprehensive coverage. 
  • Policy Restrictions: Certain supplemental plans may have waiting periods, which is the amount of time you have to wait before coverage becomes effective. Some may also exclude coverage for certain conditions. 
  • Overlapping Coverage: In some cases, supplemental health insurance coverage may overlap with the benefits already offered by your primary health insurance plan. This coverage overlap means you’re paying twice for the same thing. 
  • Limited Availability: Not all health insurance providers offer supplemental plans. And even if they do, the choices may be limited.

How to Get Supplemental Health Insurance

If you want supplemental health insurance, consider your current health needs, budget, and lifestyle. Once you know what you’re looking for, browse the internet and research each plan’s coverage, cost, limitations, exclusions, etc., to narrow down your options.

To ensure you find a plan that best suits your needs, consider chatting with an agent and getting a supplemental health insurance quote from multiple insurance providers. The application process varies depending on the insurance company, but you can typically apply online by answering some health-related questions. Once your application is submitted, the insurance companies’ underwriters will review your medical history to determine your eligibility. 

Putting It Together

The power and value of supplemental health insurance cannot be overstated. By helping you shoulder the out-of-pocket costs that most primary health insurance policies may not cover, these plans can provide much-needed relief and minimize the financial burden that comes with unexpected medical bills.

However, whether supplemental health insurance is right for you ultimately depends on your risk factors, budget, and medical needs. Speak with a licensed health insurance agent to learn more about your options. 

While you generally cannot use HSA funds to pay supplemental health insurance premiums, combining a supplemental insurance plan with a health savings account can help you manage your healthcare expenses and reduce out-of-pocket costs.

For example, imagine you suffer from a stroke and want to improve your health. You can use your HSA funds to pay for a blood pressure monitor and your critical illness insurance plan payout to cover the gym membership cost, which is typically not HSA-eligible. 

Not all alternative medical treatments are covered by a primary health insurance plan, but some supplemental health insurance policies may provide extended coverage for alternative medicine like acupuncture, chiropractic care, and massage therapy. Check with your insurance plan to see if alternative therapy is covered. 

Yes, you can generally purchase more than one supplemental health insurance policy. However, this extra coverage also means higher premiums. To avoid overpaying for health insurance coverage, carefully review each policy to ensure the coverage does not overlap with what your primary health insurance plan already provides. 

Most health insurance companies allow you to purchase a supplemental plan anytime. However, if you plan to purchase a Medicare supplement insurance plan, also known as Medigap, the best time to do so is during your Medigap Open Enrollment Period.

This period lasts six months and automatically starts once you’re enrolled in Medicare Part B and age 65 or older. Insurance companies can reject your application or charge you higher premiums based on pre-existing health conditions if you purchase Medigap outside this window.
