adverse selection

What is adverse selection?

healthinsurance.org health insurance glossary

Adverse selection refers to a situation in which the buyers and sellers of an insurance product do not have the same information available. A common example with health insurance occurs when a person waits until he knows he is sick and in need of health care before applying for a health insurance policy.

This wasn’t an option in the medically underwritten model of individual health insurance (ie, pre-2014 in most states), because pre-existing conditions were a factor in determining eligibility and price.

But since 2014, individual health insurance policies have been guaranteed issue. There was concern that this would lead to adverse selection, with healthy people opting to not purchase health insurance and simply waiting until they needed coverage before enrolling. This would result in adverse selection, which could sharply increase premiums.

Indeed, premiums did increase significantly in the individual market in 2017 and 2018, due in large part to premiums being too low in the early years of ACA implementation, uncertainty about the future of the ACA and enforcement of the individual mandate under the Trump administration, and the Trump administration’s decision to cut off CSR funding. But premiums have stabilized significantly since then, with decreases or very small increases in most places from 2019 through 2022, and fairly modest increases in 2023.

The ACA’s approach to avoiding adverse selection in a guaranteed-issue market is three-fold:

Even still, adverse selection remains a concern, especially in states where regulations and plan availability allow healthy people to buy short-term health insurance with a total duration of up to three years, Farm Bureau health plans, or health care sharing ministry coverage.

Some insurers also worry that people are “gaming the system” and qualifying for special enrollment periods when they shouldn’t. There was no widespread evidence of SEP fraud, but eligibility verification was stepped up, starting in 2106. The exchanges, including HealthCare.gov have since walked back some of this increased enforcement, although people who plan to enroll during a special enrollment period should still be prepared to provide proof of their qualifying life event.

Enrollment in off-exchange (ACA-compliant) individual/family health insurance has declined over the last several years (off-exchange enrollees have to pay full price for their coverage, as no subsidies are available outside the exchange). But on-exchange enrollment reached a record high in 2022 and again in 2023, illustrating the power of premium subsidies in keeping adverse selection at bay.
