The Private Insurance Death Spiral: What's Happening?

The death spiral is an economic phenomenon that occurs within the insurance industry, specifically when there is an imbalance in the number of healthy and sick individuals within an insurance risk pool. This imbalance leads to a cycle of increasing insurance premiums, causing healthy individuals to drop their coverage as they perceive it as no longer financially worthwhile. As a result, the average health of the insured population decreases, leading to even higher premiums. This cycle continues until the market collapses or nears collapse due to the inability of the sick individuals to afford the skyrocketing premiums. Ultimately, the insurer may report a steep loss, declare bankruptcy, or go out of business.

Premiums rise due to an increase in sick/high-cost people in the risk pool

A health insurance death spiral is a scenario in which premiums increase rapidly, causing healthy people to drop their coverage when they perceive that it is no longer worth the cost. This, in turn, causes premiums to increase even more, as the exit of healthy people leaves a smaller, less healthy risk pool.

The death spiral is the result of adverse selection in insurance policies, where lower-risk policyholders choose to change policies or go uninsured. This results in costs that are supposed to be covered by insurance being pushed back onto the insured.

In a death spiral, as premiums continue to increase, healthier people continue to drop their coverage. This adverse selection situation continues to spiral until it reaches a point where the market simply collapses. The collapse happens when coverage becomes too expensive for anyone to afford, and/or the insurers opt to exit the market altogether.

In a typical health insurance risk pool, the larger the risk pool, the more predictable and stable the premiums can be. However, the key factor in determining premiums is the average healthcare costs of the enrollees included in the pool. Thus, a large pool with a large share of unhealthy individuals can have higher-than-average premiums.

Adverse selection increases premiums for everyone in a health insurance plan or market as it results in a pool of enrollees with higher-than-average healthcare costs. As a result, some healthy individuals may opt out of coverage, leading to even higher premiums. This process is typically referred to as a "premium spiral".

Healthier people drop their insurance coverage

Healthier people dropping their insurance coverage is a key component of the private insurance death spiral. This phenomenon occurs when premiums increase rapidly, causing healthy individuals to drop their coverage as they perceive it as no longer financially worthwhile. This results in a smaller and less healthy risk pool, leading to further premium hikes. As premiums continue to rise, more healthy people opt out, creating an adverse selection situation that spirals out of control until the market collapses.

In a death spiral scenario, the number of healthy enrollees decreases sharply, while the total costs remain high due to the claims of the sickest enrollees. With a smaller pool of insured individuals, premiums rise, perpetuating the cycle. Ultimately, only those with the highest medical needs retain their coverage, and the market nears collapse.

The Affordable Care Act (ACA) has implemented strategies to prevent such death spirals, including premium subsidies, individual mandates, and annual open enrollment windows. These measures aim to ensure that healthy individuals continue to purchase coverage, stabilising the market.

The death spiral phenomenon is not limited to specific demographics or age groups. However, certain factors, such as age and health status, can influence an individual's decision to opt out of insurance coverage. For example, younger and healthier people may be more inclined to forego insurance if they believe the premiums are too high compared to the perceived benefits.

Additionally, the structure of insurance plans plays a crucial role in the death spiral. When a group insurance plan is closed to new subscribers, the average cost per member increases as the group size decreases over time. This dynamic incentivises healthier individuals to seek alternative insurance options, further contributing to the death spiral.

In summary, the concept of healthier people dropping their insurance coverage is a critical aspect of the private insurance death spiral. It involves a cycle of increasing premiums, decreasing healthy enrollees, and rising costs that eventually threaten the stability and viability of the insurance market.

Insurers face steep losses, bankruptcy or go out of business

Insurers face steep losses, bankruptcy, or going out of business when the structure of insurance plans leads to rapidly increasing premiums. This is caused by changes in the covered population, as lower-risk policyholders choose to change policies or go uninsured. This results in higher claims costs for the remaining group members, and so the insurer raises the rates to cover these higher costs.

As the premiums increase, healthier people drop their coverage, causing premiums to increase even more as the pool of insured people becomes smaller and less healthy. This is known as adverse selection and can lead to a "death spiral" for insurers. As this cycle continues, premiums become unaffordable for many, and the market collapses. Insurers then face steep losses and may even go out of business.

In the case of the Affordable Care Act in the US, the situation was exacerbated by the removal of the "individual mandate" that penalized individuals who did not purchase insurance. With no penalty for being uninsured, many healthy people chose to go without insurance, further increasing premiums for those remaining in the market.

Insurers can attempt to prevent this by creating incentives for healthy people to purchase insurance, such as offering low-deductible catastrophic plans. Additionally, government intervention in the form of premium subsidies and individual mandates can help stabilize the market and prevent a "death spiral."

The market collapses

The death spiral in private health insurance is a rare but ominous phenomenon. It occurs when there is an adverse selection of policyholders, resulting in a rapid increase in premiums. This happens when there are more sick or high-cost people insured than healthy members in the risk pool. As premiums rise, healthier people may choose to drop their coverage, further increasing premiums for the remaining policyholders. This creates a vicious cycle that can lead to a collapse of the insurance market.

The collapse occurs when insurance becomes unaffordable for most people, and insurers may exit the market. This situation is unsustainable, as insurers require a stable market with a majority of healthy enrollees to offset the costs of caring for the sickest members. When healthy enrollees decline sharply, the total costs remain high due to the high claims from the sickest enrollees. As these costs are spread over a smaller pool of insured individuals, premiums rise even higher, intensifying the death spiral cycle.

The Affordable Care Act (ACA) in the United States aimed to prevent death spirals by including premium subsidies for low-income individuals and an individual mandate requiring most Americans to have health insurance or pay a penalty. However, the removal of the individual mandate penalty in 2019 caused premiums to increase, contributing to the spiral.

The death spiral in private health insurance can have severe consequences, leading to insurers reporting steep losses, declaring bankruptcy, or going out of business. It is crucial for policymakers to address this issue and make informed decisions regarding taxpayer subsidies and the role of private health insurance in the overall healthcare system.

Government intervention and subsidies

To mitigate this, governments have implemented various measures:

Premium Subsidies:

One key intervention is offering premium subsidies to individuals, especially those with lower incomes. For instance, the Affordable Care Act (ACA) in the United States included premium subsidies for people earning up to 400% of the poverty level. Some states, like New York, also offered state-funded premium subsidies to support residents. These subsidies help make insurance more affordable, encouraging healthier individuals to maintain their coverage, thus stabilising the risk pool.

Individual Mandate:

Another strategy is an individual mandate, which requires individuals to obtain health insurance or pay a penalty. This approach, initially included in the ACA, aimed to ensure that healthy people continue to purchase coverage. While the federal penalty for non-compliance was eliminated in 2019, some states like California and New Jersey have maintained their own individual mandates.

Limited Enrollment Windows:

Governments have also implemented limited enrollment windows for purchasing individual health coverage. This makes it more challenging for people to go without coverage and then enrol only when they need medical care.

State-Level Interventions:

At the state level, governments can impose their own individual mandates, offer state-funded premium subsidies, and enact regulations to restrict access to alternative plans that could draw healthy individuals away from the ACA-compliant market. Additionally, states can seek waivers to receive federal funding for reinsurance programs or innovative approaches to control premiums.

Addressing Root Causes:

Beyond these immediate interventions, governments also need to address the root causes of the death spiral. This includes clearly defining the role of private health insurance in relation to public health care systems, such as Medicare in Australia. By establishing whether private insurance should complement or substitute public care, governments can determine the appropriate level and form of taxpayer subsidies.

In summary, government intervention and subsidies are vital tools to prevent and manage the private insurance death spiral. By providing premium subsidies, implementing individual mandates, and making regulatory adjustments, governments can stabilise insurance markets and ensure access to affordable health care for their citizens.
