Insurers fear young people will opt out

Persuading young, healthy adults such as Lopez to buy insurance under the Affordable Care Act is becoming a major concern for insurance companies as they scramble to comply with the law, which prohibits them from denying coverage because of pre-existing conditions and limits what they can charge to older policy holders. Experts warn a lot of these so-called "young invincibles" could opt to pay the fine instead of spending hundreds or thousands of dollars each year on insurance premiums. If enough young adults avoid the new insurance marketplace, it could throw off the entire equilibrium of the Affordable Care Act. Insurers are betting on the business of that group to offset the higher costs they will incur for older, sicker beneficiaries.
