The four main types
| Type | What triggers a payment | How it pays | Typical catch |
|---|---|---|---|
| Accident | An injury from a covered accident: ER visit, fracture, ambulance, imaging, hospital stay | A set amount per service on a benefit schedule | Pays nothing for illness; excludes some activities and causes |
| Critical illness | First diagnosis of a listed condition such as cancer, heart attack or stroke | One lump sum, often after a survival period of 14–30 days | Conditions must meet the policy's definitions; pre-existing conditions excluded |
| Hospital indemnity | Admission to a hospital, and each day you stay | A fixed amount per admission and per day | Pays only for covered admissions and days, up to a day limit |
| Cancer (specified disease) | Cancer diagnosis and specific treatments | Scheduled amounts per treatment, per day or a lump sum | Covers only cancer; waiting periods; skin cancer often limited |

The key feature is that these policies pay regardless of what your health insurance pays. A hospital indemnity policy that pays $300 a day for a six-day stay sends you $1,800 even if your major medical plan has already covered the hospital bill. Aflac, for example, pays cash benefits directly to you unless you choose otherwise. You can use the money for rent, groceries or your deductible.
Not health insurance, even if the brochure looks like it
Insurers must disclose that these products are not a substitute for comprehensive major medical insurance. A 2024 federal rule went further and required group fixed indemnity plans to display a notice beginning "IMPORTANT: This is a fixed indemnity policy, NOT health insurance." A federal court in Texas vacated that requirement in December 2024, and after the agencies dropped their appeal in June 2025, it is no longer in force. The warning still holds. A hospital indemnity plan paying $200 a day will not come close to a hospital bill if it is your only coverage. If you need real health coverage, start with our health insurance guide.
What these policies cost: real examples
Hospital indemnity through an employer
Many people are offered supplemental coverage at work. A MetLife hospital indemnity plan offered to University of Nevada, Las Vegas employees shows how pricing works:
| Low plan | High plan | |
|---|---|---|
| Hospital admission (non-ICU) | $500 | $1,000 |
| Daily confinement (non-ICU) | $100/day | $200/day |
| ICU admission / daily | $1,000 / $200/day | $2,000 / $400/day |
| Employee-only premium | $13.71/mo | $27.14/mo |
| Employee + spouse + children | $32.62/mo | $63.96/mo |
Source: MetLife hospital indemnity plan summary for UNLV employees (©2024). Daily benefits run up to 30 days for sickness and 31 for accidents. A pre-existing condition exclusion applies to sickness.
Run the numbers on a four-day non-ICU stay. The high plan pays $1,000 plus 4 × $200, or $1,800. Its employee-only premium costs $325.68 a year. You would come out ahead in any year with a hospital stay, and behind in every year without one.
Critical illness
Research published by NerdWallet in 2023 found the most popular critical illness policies offer $50,000 of coverage, and a healthy 30-year-old man in Iowa could then get a policy from Assurity for about $29 a month, or about $25 a month for a woman. Premiums rise with age. Aflac describes monthly critical illness premiums as ranging from $20 to $50 or more depending on age, health and benefit amount.
Accident and cancer
Aflac does not publish accident or cancer premiums online; prices come through an agent and vary by state and plan level. Ask for the full benefit schedule so you can see what a typical injury or diagnosis would actually pay.
Exclusions to read before you buy
Accident policies exclude sickness entirely. Aflac's accident disclosures also exclude injuries tied to intoxication or illegal drug use, self-inflicted injuries, military service or war, committing a felony, cosmetic or elective procedures, and dental treatment unless it results from an injury. Some versions exclude on-the-job injuries.
Cancer policies often have a waiting period. Under one Aflac policy series in Idaho, the wait is 30 days; if you are diagnosed during it, treatment benefits start on day 31 and you can cancel for a premium refund. The initial diagnosis benefit is not paid for nonmelanoma skin cancer under the state policies Aflac lists, and premalignant conditions are not covered. Cancer diagnosed or treated before the policy started may be excluded from the diagnosis benefit.
Critical illness policies exclude pre-existing conditions, and a diagnosis has to meet the policy's definition. A mild heart event may not qualify. Many require you to survive a set period after diagnosis before the benefit is paid.
Hospital indemnity policies can exclude sickness tied to pre-existing conditions and cap the number of paid days. The MetLife plan above does both, paying up to 30 days for a sickness.
A cancer insurance guide that Louisiana's Division of Administration publishes for state employees suggests asking how pre-existing conditions are handled, whether there is a waiting period, what limits apply to chemotherapy, and whether benefits are paid per treatment, per day or as a lump sum. Those questions work for every supplemental policy.
Supplemental insurance vs. an emergency fund or HSA
A supplemental policy is a bet on a specific event. Savings cover any event. Compare what each gives you:
- An HSA paired with a high-deductible plan lets you save pre-tax for medical costs. For 2026 the IRS allows $4,400 for self-only coverage and $8,750 for family coverage. High-deductible plans can have out-of-pocket maximums as high as $8,500 for self-only coverage, so an HSA balance can cover the whole gap over time.
- An emergency fund covers medical bills, lost wages and anything else. Our emergency fund guide covers how much to keep.
- A supplemental policy protects you right away, even before savings have built up, but only for the listed events.
Supplemental coverage tends to fit when your deductible is high, your savings are thin, and the premium is small relative to your budget. NerdWallet's research also points to people who cannot get disability insurance, such as stay-at-home parents, freelancers and part-time workers, and people with a family history of serious illness. It tends to be a poor fit when you can already cover your out-of-pocket maximum from savings. If your real worry is losing income for months, disability insurance addresses that more directly. If you want to protect your family after your death, life insurance comes first.
Employer plans vs. buying on your own
- Payroll deduction. Workplace plans are usually paid through payroll. The MetLife example above costs $13.71 to $27.14 a month for an employee.
- Taxes. According to HUB International's summary of a 2023 IRS memo, if you pay fixed indemnity premiums with pre-tax dollars, the benefits can be taxable to the extent they exceed your unreimbursed medical expenses. Paying premiums with after-tax dollars generally keeps benefits tax-free. Ask your benefits office how premiums are deducted.
- Leaving your job. Ask whether the policy is portable. Some group accident policies let you keep coverage when you change jobs; others end with employment.
- Critical illness riders. Some term life policies offer a critical illness rider instead of a separate policy. A payout reduces the death benefit: a $50,000 claim on a $500,000 policy leaves $450,000.
Named carriers to know
Aflac sells accident, cancer, critical illness and hospital indemnity policies and pays benefits directly to the policyholder. MetLife sells group hospital indemnity and critical illness coverage through employers, as in the UNLV example. Aflac, Colonial Life, National Teachers Associates Life and Washington National were listed by Louisiana's Division of Administration as selling cancer policies to state employees, and Assurity was the critical illness insurer in NerdWallet's pricing research. Product availability and terms vary by state, so compare the outline of coverage rather than the brand.
Checklist before you buy
- Write down your health plan's deductible and out-of-pocket maximum, and how much cash you could pay today.
- Price the supplemental policy for a year and compare it with what a likely claim would pay.
- Read the benefit schedule, exclusions, waiting period and pre-existing condition rules.
- Check whether premiums are pre-tax or after-tax and whether the policy is portable.
- Avoid buying several policies that overlap. A cancer policy and a critical illness policy that both pay for cancer may be more than you need.
Frequently asked questions
Does supplemental insurance replace health insurance?
No. Supplemental policies pay fixed cash amounts for specific events, such as a hospital stay or a cancer diagnosis. They are not comprehensive medical coverage and will not pay most of a large medical bill on their own.
Who gets the money from a supplemental policy?
Usually you do. Aflac, for example, pays cash benefits directly to the policyholder unless you choose to assign them. You can spend the money on medical bills or everyday expenses.
Are supplemental insurance benefits taxable?
It depends on how you pay the premium. HUB International's summary of a 2023 IRS memo says that when fixed indemnity premiums are paid pre-tax, benefits can be taxable to the extent they exceed unreimbursed medical expenses. Benefits are generally tax-free when premiums are paid after tax.
Is critical illness insurance worth it?
It can be if you have a high deductible and little savings, or no access to disability insurance. If you can already cover your out-of-pocket maximum from savings or an HSA, the premium may be better spent building those.
Does cancer insurance cover a cancer I already have?
Generally not. Policies commonly exclude cancer diagnosed or treated before coverage starts and may have a waiting period, such as 30 days under one Aflac policy series.
What is the difference between hospital indemnity and critical illness insurance?
Hospital indemnity pays a fixed amount per covered admission and per day in the hospital, subject to the policy's exclusions. Critical illness pays one lump sum when you are diagnosed with a listed condition, whether or not you are hospitalized.
