Note (September 2026): An earlier version said critical illness insurance was developed in 1996 and that benefit limits ranged from a few dollars to over a hundred dollars. The first policy was launched in South Africa in 1983, and US benefit amounts typically run to thousands of dollars.
Critical illness insurance, a type of specified disease insurance, pays a fixed cash benefit, usually a lump sum, when the policyholder is diagnosed with a condition listed in the policy, such as cancer, heart attack or stroke. The money goes to the policyholder and can be spent on anything. It supplements health insurance and does not replace it.
Key Takeaways
- Critical illness insurance was first launched on 6 October 1983 in South Africa, as “dread disease” cover founded by cardiac surgeon Dr. Marius Barnard, according to Wikipedia.
- In the US, specified disease and critical illness plans are HIPAA “excepted benefits”: they are regulated mainly by the states and are not comprehensive medical coverage under the Affordable Care Act.
- Benefits are fixed amounts, not reimbursement of bills. The average new US benefit was $21,993 for individual policies and $14,766 for group/worksite policies, according to a 2020 American Association for Critical Illness Insurance report cited by Wikipedia.
- Pre-existing condition limits, waiting periods, survival periods, reduced payouts for early-stage cancers and one-time benefit rules are the terms that most often decide whether a claim pays.
Insurance is a topic that is never getting off from the global health conversation any time soon. Considering the rising cases of new infectious and critical diseases, it is certain that healthcare stakeholders and other institutions such as the government will continue championing health care plans with insurance topping the list.
Over time the insurance industry has witnessed a growth in several bands. New methods are now available, including the specified disease insurance covers to combat critical illnesses such as cancer.
Talking of catastrophic diseases, many will not understand the benefits insurance has brought towards supporting the world’s quest to eradicate such conditions as stroke and heart attacks, among others.
Ordinarily, a standard conventional insurance cover is enough for most people who take note of protecting their health and that of their loved ones. Many have no idea if such healthcare plans as critical illness insurance exist, and vigorous awareness campaigns are needed.
Traditional health insurance can pay for much of the treatment of a serious illness, but deductibles, copays, coinsurance, travel and lost income can still leave patients with large costs. For this reason, insurers developed critical illness insurance, which pays a fixed cash benefit that patients can use to cover those costs.
Specified Disease Insurance 101
Old age is admired by many Americans even as life expectancy continues to increase. However, it is not easy considering the inflation of medical care and the rise of terrible diseases, impacting the old population and even the younger generation.
As such, the insurance industry is continually coming up with ways to help people afford quality healthcare and later the privilege of getting to the much desired older age.
Critical illness insurance dates from 1983, not 1996. According to Wikipedia, the first policy was launched on 6 October 1983 in South Africa by Crusader Life Assurance under the name “dread disease insurance”, founded by cardiac surgeon Dr. Marius Barnard, and it originally covered four conditions: cancer, stroke, heart attack and coronary bypass surgery. The year 1996 matters for a different reason: the US Health Insurance Portability and Accountability Act (HIPAA) of 1996 created the “excepted benefits” category under which specified disease and critical illness plans are regulated today.
Some advisors still claim that no amount of insurance cover could completely deal with the enormous financial burden after treating a critical condition. To some extent, this is true: specified disease plans are not designed to pay the full cost of medical treatment, but the cash benefit can ease the out-of-pocket burden that remains after regular health insurance has paid.
What can a Critical Illness Insurance Do?
Unlike conventional health insurance, which pays doctors and hospitals for covered care, critical illness insurance usually pays a fixed cash benefit directly to the policyholder, who can use it for a range of expenses, including those indirectly related to treatment. For instance, the money can pay for travel between home and hospital, and some policies add a separate transportation benefit, such as the $100 per hospital round trip listed in one Aflac critical illness policy outline.
Other expenses, such as food and childcare, can also be paid from the benefit, because the insurer does not dictate how the money is spent. However, just like any insurance cover, there is a limit: the benefit is a fixed amount chosen when the policy is bought, usually thousands of dollars rather than a few dollars. The average new US benefit was $21,993 for traditional individual policies and $14,766 for group/worksite policies, according to a 2020 American Association for Critical Illness Insurance report cited by Wikipedia.
The factors that determine whether an applicant is accepted, at what premium and with which exclusions include age, sex, smoking status, past medical history, family medical history, alcohol consumption and body mass index, according to Wikipedia’s summary of critical illness underwriting.
Exceptions to Catastrophic Illness Insurance
Though this healthcare plan covers a range of critical complications, there are other types of diseases that critical illness insurance cannot cover. Not all cancers are eligible for full coverage by this type of healthcare plan: many policies pay a reduced amount, or nothing, for early-stage cancers. The Aflac policy outline, for example, pays 25% of the face amount for noninvasive cancer and $200 for nonmelanoma skin cancer.
Additionally, the insurance on many occasions does not cover costs incurred in dealing with chronic diseases. It is also essential to note that many policies pay only once for the same critical illness, for example, a second stroke, although some include a recurrence benefit. The Aflac policy outline pays 50% of the face amount for a recurrence of the same event or a different covered event, with no lifetime maximum, and for a recurring cancer it first requires 12 consecutive months free of treatment.
In some cases, the insurance plan ceases to protect a person once they have reached a given age; others, such as guaranteed-renewable policies, stay in force for life as long as the premiums are paid. It is essential to understand the terms and conditions set for such insurance covers before purchasing them.
Importance of this Insurance Plan
Today companies acknowledge the benefits of adding this insurance plan to their healthcare plans. Many employers recognize how burdensome it is to always pay for medical bills through out-of-pocket funds and have opted to introduce critical illnesses insurance to employees.
When employees pay the premiums, the employer can offer this coverage without adding to its own health plan costs. According to an American Council of Life Insurers (ACLI) presentation to the National Association of Insurance Commissioners (NAIC) in September 2021, 96% of supplemental accident, hospital indemnity and specified disease/critical illness policies are made available through employers. Some of the ways this type of insurance have proven helpful include.
- Sorting out medical bills for extensive and critical medical treatment.
- The cash can pay for transportation linked to the treatment schedule. Some patients will have to retrofit their cars and provide ease in movement. All this can be paid from the lump sum, up to the policy’s benefit amount.
- Daily living expenses can be paid from the benefit, up to its limit, to allow them to focus their strength and mind towards getting healed.
- Recuperating patients can use funds from the cover to go on a vacation with family to a restful place that would hasten their recovery.
What Is Specified Disease Insurance?
Specified disease insurance is supplemental coverage that pays a benefit when the insured person is diagnosed with a disease or condition named in the policy. According to an ACLI presentation to the NAIC in September 2021, these plans pay either a lump sum, which is more common, or a fixed dollar amount for each eligible service. Cancer-only policies are one example.
Critical illness insurance is a subcategory of specified disease insurance. It usually pays a lump sum when the insured person is diagnosed with one or more major illnesses listed in the policy at the time of sale, such as cancer, stroke or multiple sclerosis. Outside the US, similar products are also called dread disease cover, trauma insurance or living assurance.
How are these plans regulated in the US?
Specified disease and critical illness plans are HIPAA “excepted benefits”. According to the same ACLI presentation, excepted benefits are regulated differently from major medical plans, primary regulatory authority lies with the states, and they are not subject to the Affordable Care Act. Because rules differ by state, the state insurance department is the place to check what a policy sold where you live must include.
What these plans are not
- They are not comprehensive medical coverage and are not meant to be sold as such.
- They do not pay directly for medical expenses or claims and cannot pay benefits on an expense-incurred basis.
- They cannot vary their benefits based on other insurance the policyholder has.
How Does Critical Illness Insurance Work?
Critical illness insurance works in a fixed sequence, from buying the policy to receiving the cash. The exact rules are set by each policy, so the steps below describe the common pattern rather than any single contract.
- Choose a benefit amount. The face amount is fixed at purchase. Some policies pay a reduced share for family members; the Aflac outline pays 50% of the face amount for a covered spouse or dependent child.
- Pass underwriting. Individual policies are usually underwritten, so the insurer can assess each applicant’s risk. Group products sold through employers are often at least partly guaranteed issue, according to the ACLI presentation.
- Serve any waiting period. Some policies do not pay for conditions diagnosed soon after coverage starts. The Aflac outline has a 30-day waiting period for internal cancer.
- Receive a diagnosis that meets the policy definition. The contract defines when a diagnosis counts, and it may require a specialist or specific tests, according to Wikipedia.
- Survive any survival period. Some policies require the policyholder to survive a set number of days after diagnosis; Wikipedia notes that 14 days is the most typical survival period.
- File the claim and receive the cash. The benefit is usually paid directly to the insured person, who decides how to use it.
Critical Illness Insurance vs. Health Insurance vs. Hospital Indemnity
Critical illness insurance, major medical health insurance and hospital indemnity insurance answer different needs. The table summarizes the differences described in the ACLI presentation to the NAIC.
| Feature | Major medical health insurance | Critical illness / specified disease | Hospital indemnity |
|---|---|---|---|
| What triggers payment | Covered medical services | Diagnosis of a listed condition | Hospital admission or listed outpatient care |
| How it pays | Pays for covered medical expenses | Lump sum (more common) or fixed amount per service | Fixed amount, often a daily benefit per day in hospital |
| Who usually receives the money | Often the doctor or hospital | The insured person | The insured person |
| How the money can be used | Covered care only | Any purpose | Any purpose |
| Subject to the Affordable Care Act | Yes | No (HIPAA excepted benefit) | No (HIPAA excepted benefit) |
Example: What One Critical Illness Policy Pays
An Aflac individual lump-sum critical illness policy outline (form B71225, dated August 2018) shows how the terms work in practice. It is one example only; benefits, riders and limits differ by insurer, policy form and state.
- Covered events: heart attack, sudden cardiac arrest, stroke, major human organ transplant, end-stage renal failure, bone marrow transplant and internal cancer.
- Initial diagnosis benefit: 100% of the face amount for the named insured and 50% for a spouse or dependent child, once per person per lifetime.
- Subsequent event benefit: 50% of the face amount for a recurrence or a different covered event, with no lifetime maximum.
- Partial benefits: 25% for coronary artery bypass graft surgery, 25% for noninvasive cancer and $200 for nonmelanoma skin cancer.
- Pre-existing conditions: no benefit for a loss caused by a condition treated, medicated or symptomatic in the 12 months before coverage began, unless the loss begins more than 12 months after the effective date.
- Exclusions include: infections, medical errors or malpractice, hazardous activities such as skydiving and scuba diving, and losses diagnosed or treated outside the US, its possessions, Canada and Mexico.
- Renewability: guaranteed renewable for life while premiums are paid; premiums can change only for a whole class of policyholders.
How Common Is Critical Illness Insurance in the US?
Specified disease and critical illness coverage is widely held in the US, mostly through the workplace. According to an ACLI survey of its members in April 2021, there were 10,639,768 active specified disease/critical illness policies and certificates, a figure the ACLI says is undercounted because several supplemental carriers are not members. The same presentation states that 96% of supplemental policies are made available through employers and 4% are sold without employer involvement, mostly through direct mail or independent agents.
Buyers are typically in mid-career. The average age at purchase was 46.0 years for traditional individual critical illness insurance and 42.2 years for group/worksite coverage, according to 2020 American Association for Critical Illness Insurance figures cited by Wikipedia.
What to Check Before Buying Critical Illness Insurance
- The list of conditions and their definitions: a condition that is not listed, or that does not meet the policy’s definition, does not pay.
- Partial-payment rules: check how early-stage cancer, bypass surgery and skin cancer are treated.
- Pre-existing condition rules: for example, a 12-month look-back before coverage starts and a 12-month exclusion after it.
- Waiting and survival periods: both can delay or prevent a payout.
- Recurrence and second-event benefits: whether a second diagnosis pays, how much, and after what treatment-free interval.
- Renewability and age limits: guaranteed renewable for life, or ending at a set age.
- Your existing coverage: critical illness insurance is designed to supplement insurance already in force, not to replace a major medical plan.
