Adverse Selection

Clinical genetics An event in which an insurer avoids underwriting a person whose genetic profile indicates a high chance of suffering an "expensive" condition in the future—e.g., Huntington’s disease (Armed with such information, an insurance carrier may deny coverage—i.e., adversely select—a person with a high risk of suffering the disease in question; alternatively, that person may take out a large insurance policy on standard terms).
Health insurance The tendency of those with greater-than-average health risks to apply for, or maintain, insurance coverage.
Managed Care
(1) A stance adopted by health care insurers, which fiercely compete among themselves to insure the healthiest and wealthiest segment of a particular population, and thus adversely select the population which they target for selling insurance policies.
(2) The selection of a health plan, whether indemnity or managed care, over other plans by those enrollees who are more likely to file claims and use services, causing an inequitable proportion of enrollees requiring more medical services in that plan.
