Adverse Selection: What Is It & How It Works

There has long been a problem in health insurance known as adverse selection, which leads to an uneven distribution of costs between the healthy and unhealthy. Here’s how it works.
Adverse Selection: What Is It & How It Works

Adverse selection in health insurance can be a daunting concept to understand, but it’s one that’s essential for anyone looking to get the best health coverage possible. Adverse selection is an economic concept where individuals select certain products or services based on information that they have which others don’t. In the case of health insurance, it occurs when consumers with pre-existing conditions know they will need medical care and are more likely to purchase coverage than healthier individuals. This can lead to higher premiums due to the increased risk pool, as well as limited options in terms of coverage and providers, which are further compounded by limited enrollment periods throughout the year. Additionally, a lack of transparency and knowledge of their current medical state may cause individuals to wait until close to or after these enrollment periods before signing up for coverage. This leads to the insurer bearing a larger risk pool in terms of both those covered and the potential costs associated with them.

Knowing how it works and its potential ramifications will help individuals to make informed decisions when purchasing health insurance, ensure they are getting the best deal for their money, and ultimately protect their financial security. Therefore, individuals should become familiar with this phenomenon and learn about how it affects them and their family.

What Is Adverse Selection?

Adverse selection is the phenomenon where individuals with higher risk of requiring medical care are more likely to purchase health insurance, leading to higher premiums for everyone due to a higher risk pool. This can lead to increased costs for individuals, as well as make healthcare unaffordable for many. It also results in insurance companies being less likely to accept certain individuals or charging them more due to their increased risk. Additionally, it can lead to an increase in the cost of health care services and a decrease in overall quality of care.

Adverse selection can also be seen in the case of high deductible health plans. In this type of plan, individuals are required to pay a large deductible up front before their coverage begins. Individuals in poor health may be more likely to sign up for a plan with a higher deductible since they expect to have greater medical expenses and thus receive a better overall value from the plan. Those with better health, however, would opt for lower deductible plans as they expect to have fewer healthcare needs and don’t need to incur the expense of a larger upfront cost. Ultimately, this results in a pool of people with higher expected costs and premiums that rise accordingly, making it difficult for those with lower expected costs to get coverage.

Another example of adverse selection can be seen in plans with various riders and other add-ons. Individuals who are expecting a high level of medical care may opt for plans that offer additional coverage for services such as doctor visits, hospital stays, medications, or even dental care. This serves to drive up the cost of insurance for all involved as the pool of insured individuals becomes biased towards those expecting higher medical costs. As a result, premiums rise across the board making it difficult for others to obtain quality coverage at an affordable price.

Making health insurance enrollment easier can lead to higher premiums due to adverse selection. A study published by the Commonwealth Fund found that making the process easier could cause an increase in adverse selection, and therefore higher premiums for those with pre-existing conditions. Another study published in Health Economics Review concluded that pre-existing or chronic health conditions can increase the likelihood of adverse selection in rural insurance markets. Additionally, research from the American Economic Review showed that between 2008 and 2010, more than half of the increase in premiums was due to adverse selection.

How Does The Affordable Care Act Reduce Adverse Selection?

The Affordable Care Act (ACA) was designed to reduce the effects of adverse selection in the guaranteed-issue market by including certain provisions within the law. Specifically, the ACA required insurers to issue insurance to everyone who applied regardless of any pre-existing conditions they may have. Additionally, it barred insurers from charging higher premiums to those with pre-existing conditions or other high-risk factors. These provisions helped reduce the impact of adverse selection that can occur when an individual knows more about their personal health status than an insurer does. In addition, it also encouraged individuals to purchase insurance earlier rather than waiting until they need care since they would not be subject to higher premiums or denied coverage due to a pre-existing condition.

Here are some of the features included in ACA that were designed to prevent adverse selection in the marketplace:

  • Individual Mandate: The individual mandate requires all individuals to have insurance coverage or face a penalty. This encourages healthy individuals to purchase insurance and helps to balance out the risk pool by discouraging those with pre-existing conditions from waiting until they need care before purchasing insurance.
  • Enrollment Periods: The ACA also provides for limited enrollment periods throughout the year during which insurers can accept new customers. This helps prevent adverse selection by providing a window of time in which potential customers are required to purchase coverage before any pre-existing conditions develop.
  • Premium Subsidies: The ACA also offers subsidies on premiums for low-income individuals, making health insurance more affordable and encouraging them to purchase coverage rather than opting out due to cost concerns. This helps reduce the effect of adverse selection as it reduces the incentive for individuals to wait until they become ill before signing up for a health plan.

How Does Moral Hazard Lead to Adverse Selection in Health Insurance?

Moral hazard is a term used to describe the behavior of individuals when their actions are no longer constrained by the risk of personal consequences. In regard to health insurance, this can result in individuals taking risks or using more healthcare services than necessary due to the knowledge that their costs are covered by insurance. This can lead to adverse selection, as healthy individuals may opt out of coverage because of this increased cost and those with pre-existing conditions may be more likely to purchase coverage due to an increase in utilization. Thus, moral hazard can lead to an unbalanced risk pool, resulting in higher premiums for those with pre-existing conditions and driving up the cost of care for everyone.

Strategies that can be done to mitigate both adverse selection and moral hazard in health insurance plans include:

  • Increasing transparency in terms of pricing, coverage, and any restrictions or limitations placed on the policy.
  • Establishing open enrollment periods throughout the year, instead of just one annual window, so that consumers can sign up for coverage if they need it at any time.
  • Offering incentives for healthy behavior, such as discounts on premiums or rewards for maintaining a healthy lifestyle.
  • Setting premiums based on age or health status of individual policyholders, instead of basing them on larger risk pools.
  • Encouraging preventive care by providing incentives such as lower co-pays or no co-pays for preventive services like vaccines or checkups.
  • Providing educational materials and resources to help people make informed decisions about their coverage options and to better understand how health insurance works.v
