Is secondary health insurance worth it?

Editorial team Published on

Supplemental health insurance is worth it if you have a high-deductible plan, low personal savings, or a high risk of specific medical issues, but it may be a waste of money if you already have robust coverage or can easily pay out-of-pocket expenses.

How Supplemental Insurance Works

  • Cash payout: Many plans pay you a flat lump sum directly. You can use this money for anything, like groceries, rent, or medical bills.
  • Gap coverage: Other plans cover specific services your main insurance skips, like dental care, vision care, or specific hospital fees.
  • Not a replacement: It is an add-on policy. It does not replace your primary health insurance.

When It Is Worth It

  • High deductibles: You have a high-deductible health plan (HDHP) and would struggle to pay a large unexpected medical bill.
  • Family medical history: You have a high risk for specific critical illnesses like cancer or heart disease.
  • Limited savings: You do not have an emergency fund to cover missed work or high copays.
  • Medicare gaps: You use Original Medicare and want a Medigap plan to cover coinsurance and copays.

When It Is Not Worth It

  • Strong primary plan: Your main health insurance has a very low deductible and low out-of-pocket maximums.
  • Good savings: You have enough money saved in an emergency fund or a Health Savings Account (HSA) to handle medical surprises.
  • Strict limits: The policy excludes pre-existing conditions or has too many fine-print rules that make payouts unlikely.

What are the downsides of having supplemental insurance?

The main downside of supplemental insurance is that it adds an extra monthly premium on top of your primary policy while often excluding prescription drugs, vision, and dental benefits.

Financial and Cost Drawbacks

  • Extra Monthly Costs: You must pay a separate monthly premium alongside your base policy or standard Medicare, which can become expensive over time.
  • Rising Premiums: Many supplemental plans increase their rates as you get older or based on inflation, making them costly for people in good health who rarely use care.
  • Over-insurance Risk: If your primary health needs are low, the steady monthly cost of the supplement can exceed the actual out-of-pocket expenses it saves you from paying.

Coverage Limitations

  • No Prescription Drugs: Most medical supplemental insurance (like Medigap) does not cover prescription medications, requiring you to buy a separate standalone plan like Medicare Part D.
  • No Extra Perks: Standard supplemental policies do not cover routine dental, vision, or hearing care.
  • Strict Payout Rules: Specialized policies, such as critical illness or hospital indemnity insurance, only pay out for very specific diagnoses or event triggers, meaning they won't help if your specific condition isn't listed. They also cannot be used as standalone comprehensive coverage.

Enrollment and Underwriting Restrictions

  • Underwriting Hurdles: If you miss your initial open enrollment window (such as the 6-month window when turning 65 and enrolling in Medicare Part B), insurers can review your medical history.
  • Denial of Coverage: Outside of guaranteed-issue periods, companies can charge you higher rates or deny coverage entirely due to pre-existing medical conditions.

Opinions on Reddit are mixed; some users feel supplemental plans are overpriced and prefer alternatives like Medicare Advantage, while others warn that Advantage plans come with restrictive networks and strict pre-authorizations.

What is the average cost of secondary health insurance?

The average cost of secondary or supplemental health insurance typically ranges from $50 to $300 per month, depending on whether you mean a Medicare supplemental plan (Medigap) or a second major medical plan.

Medicare Supplemental Insurance (Medigap)

If you have Original Medicare and want a secondary plan to cover out-of-pocket costs like deductibles and coinsurance, average costs vary by plan type:

  • Plan G: Averages $142 to $180 per month (the most popular choice for new enrollees).
  • Plan N: Averages $112 to $140 per month (features lower premiums with small copays).
  • High-Deductible Plan G: Averages $50 to $55 per month.
  • Plan F: Averages $185 to $228 per month (only available if you were Medicare-eligible before 2020).

Dual Major Medical Coverage

If you are combining two commercial or employer-sponsored health plans (such as being covered under your own job and your spouse's job), you generally do not pay an extra "secondary" fee. Instead, you pay the standard monthly premium for each individual primary or secondary Forbes Advisor, where an individual ACA marketplace plan averages around $420 a month for a bronze tier and $549 a month for a silver tier.

What does secondary health insurance cover?

Secondary health insurance covers the remaining out-of-pocket costs left over after your primary health insurance pays its share.

What It Covers

  • Copayments and Coinsurance: The set fees or percentage of the bill you owe after meeting a deductible.
  • Deductibles: The amount you must pay out of pocket before your primary plan starts paying, which the secondary plan may help chip away at.
  • Remaining Balances: Leftover portions of a medical bill up to the secondary plan's coverage limit.
  • Specific Services: Services or prescription drugs that are covered under the secondary plan's rules, even if the primary plan covers them only partially.

What It Does Not Cover

  • Primary Denials: It generally does not pay for services that your primary insurance completely denies or excludes from its policy.
  • Double Pay: It does not give you extra cash or a double refund; total payouts from both plans combined cannot exceed 100% of the total medical charges.

Do I have to tell my primary insurance about my secondary insurance?

Yes, you must tell your primary insurance about your secondary insurance so they can coordinate your benefits correctly.

Why You Must Tell Them

  • Coordination of Benefits (COB): Insurance companies use COB rules to decide which plan pays first and to make sure total payouts never go over 100% of the medical bill.
  • Correct Billing Order: Your medical providers and insurers need the complete picture to bill the primary payer first and the secondary payer second.
  • Avoiding Delays and Denials: If your primary insurance does not know about your other coverage, or if claims are submitted out of order, your claims can be delayed or rejected.

How It Works

  • Primary Payer: Pays up to its policy limits first.
  • Secondary Payer: Steps in to cover remaining out-of-pocket costs like deductibles or copayments only after the primary insurer processes the claim.
  • Updating Records: You should inform both your healthcare providers and your insurance companies whenever you add, change, or drop coverage. You can check official guidance like the Medicare Coordination of Benefits page if government plans are involved.

Is it actually cheaper to not have health insurance?

It can be cheaper to go without health insurance for minor, routine care if you are completely healthy, but it is a massive financial risk for major medical emergencies.

When No Insurance Is Cheaper

  • Routine and Predictable Care: If you rarely see a doctor, paying cash for an occasional checkup, generic prescription drug, or lab test can cost less than paying a monthly insurance premium plus a high deductible.
  • Cash Discounts: Some doctors and hospitals offer lower self-pay or cash-only prices because they avoid the paperwork and administrative fees tied to insurance. Studies show that uninsured cash prices for some hospital services are occasionally lower than what insurers negotiate.

The Hidden Financial Dangers

  • Catastrophic Costs: Insurance acts as a safety net. A sudden accident, emergency room visit, or unexpected diagnosis like cancer can lead to hospital bills totaling tens or hundreds of thousands of dollars.
  • No Deductible Credit: Any cash payments you make out-of-pocket do not count toward an annual deductible or out-of-pocket maximum, leaving you with zero financial protection if a health crisis strikes later in the year.
  • State Penalties: Depending on where you live, some states require you to have coverage or face a state tax penalty.

For a deeper look into your options, you can check resources like Newsweek's guide on uninsured care or NBC News on paying for medical care without insurance.

Why would someone want supplemental insurance?

Someone would want supplemental insurance to cover out-of-pocket costs, deductibles, and gaps that standard health or primary insurance policies leave behind.

Key Reasons to Get Supplemental Insurance

  • Cover out-of-pocket gaps: Standard plans often require high copays, coinsurance, and deductibles. Supplemental insurance helps pay for these leftover expenses.
  • Receive direct cash payments: Many supplemental policies (like critical illness or accident insurance) pay a lump-sum directly to you rather than the doctor. You can use this cash for daily living costs like groceries, rent, or utilities if you cannot work.
  • Fill Medicare gaps: Original Medicare leaves out certain costs, such as the 20% Part B coinsurance and hospital deductibles. A Medicare Supplement (Medigap) plan helps cover these un-reimbursed amounts.
  • Pay for excluded care: Standard health policies often exclude specific items like dental, vision, or hearing care. Supplemental plans add targeted coverage for these needs.
  • Gain financial predictability: Extra coverage limits unexpected medical debt and provides peace of mind during a major health crisis.

Is it worth it to get secondary health insurance?

Getting secondary health insurance is usually worth it only if you expect high medical costs or can get the second plan for little to no cost.

For most healthy people who rarely see a doctor, paying two monthly premiums and managing two deductibles costs more than it saves. However, dual coverage can be a smart financial safety net in specific situations.

When Secondary Insurance Is Worth It

  • High Expected Medical Care: If you plan to have surgery, manage a chronic condition, or expand your family, a second plan can help pay for leftover copays, coinsurance, and deductibles.
  • Low-Cost or Free Coverage: If you can be added to a spouse's or parent's employer plan at little to no extra cost, the added safety net often makes financial sense.
  • Medicare Supplementation: Original Medicare does not cover everything (like dental, vision, or long-term hospital stays), making a Medigap or secondary plan very valuable during retirement.
  • Network Gaps: If an important doctor is out-of-network on your primary plan but in-network on your secondary plan, the second policy can unlock affordable care.

The Drawbacks to Consider

  • Double Fixed Costs: You must pay two separate monthly premiums and work to satisfy two separate deductibles before full coverage kicks in.
  • No Double Payouts: Insurance companies use a rule called Coordination of Benefits. This means they work together so you never make a profit or get reimbursed twice for the same bill; the secondary plan only covers what the first plan leaves behind.
  • Administrative Hassle: Juggling two provider networks, different rules, and extra paperwork can lead to delayed claims or billing confusion.

As Forbes Advisor notes, you should weigh the cost of the extra premium against what you realistically expect to spend on medical care.

Is $400 a month a lot for health insurance?

Whether $400 a month is a lot for health insurance depends entirely on whether it is an employer-sponsored plan or an individual marketplace plan.

Employer-Sponsored vs. Marketplace Costs

  • If it is through a job: Paying $400 a month for single coverage is on the high side. On average, workers with employer-sponsored single coverage pay about $120 a month, while the total premium averages $777 (with the employer paying the rest). An employer plan costing $400 is nearly triple the national average for employee contributions.
  • If it is from the ACA Marketplace: Paying $400 a month is reasonable or even cheap for an individual. The national average cost for an ACA marketplace benchmark plan before subsidies is around $625 a month. If you receive a subsidy (tax credit) based on your income, $400 a month falls right into standard individual market rates.

When $400 Is a Good Deal vs. A Bad Deal

  • Good deal: If the $400 plan has a low deductible, low copays, and a small out-of-pocket maximum, it can save you money if you need regular medical care.
  • Bad deal: If the $400 plan has a high deductible and requires you to pay for most of your care before the insurance kicks in, you may be overpaying—especially if it's through an employer. Under Affordable Care Act (ACA) standards, if an employer-sponsored self-only plan costs more than a specific percentage of your household income, it is considered "unaffordable", meaning you might qualify for subsidies on the public marketplace.

Opinions on Facebook are mixed regarding monthly healthcare costs, with some individuals paying under $150 through employers while others pay over $1,000 for comprehensive or family coverage.

What is the best secondary health insurance?

The best secondary health insurance, usually called a Medicare Supplement (Medigap) plan for people on Original Medicare, depends on your budget and coverage needs, with State Farm and AARP/UnitedHealthcare ranked as top overall providers.

Top Secondary Insurance Companies

  • Plan N: Offers lower monthly premiums in exchange for small, predictable copayments for certain doctor and emergency room visits.
