Final answer:
It is true that an eligible individual must enroll within a specified eligibility period to obtain group health insurance without evidence of insurability. This practice helps mitigate the adverse selection problem and allows for more reasonable health plans.
Step-by-step explanation:
An eligible individual who would like to obtain group health insurance without providing evidence of insurability must enroll within a specified eligibility period is True. In the context of the U.S. health insurance market, particularly under The Patient Protection and Affordable Care Act, individuals are often provided the opportunity to enroll in group health insurance through their employment without the need to prove insurability, as long as they do so during the specified eligibility period. This is part of the effort to address the adverse selection problem in health insurance, where insurance companies are concerned about only high-risk individuals seeking coverage, which can lead to higher premiums. By enrolling a diverse group of individuals, including those with low risk, along with high-risk individuals, insurance companies can offer more reasonable plans. Moreover, the individual mandate required all individuals to have health insurance or face a penalty, further ensuring that people of varying health levels participated in the health insurance market.
