Before the development of medical expense insurance, patients were expected to pay all other health care costs out of their own pockets, under what is known as the fee-for-service business model. During the middle to late 20th century, traditional disability insurance evolved into modern health insurance programs. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, and emergency health care procedures, and also most prescription drugs, but this was not always the case. The rise of private insurance was accompanied by the gradual expansion of public insurance programs for those who could not acquire coverage through the market.
Critics said that "Exemptions would lead to market instability and higher premiums in the traditional small-group market. AHPs exempt from state regulation and oversight would enable them to be more selective about who they cover. They will be less likely to cover higher-risk populations, which would cause an imbalance in the risk pool for other small business health plans that are part of the state small group risk pool. Adverse selection would likely abound and Association Health Plans would be selling an unregulated product alongside small group plans, which creates an unlevel playing field." According to the Congressional Budget Office (CBO), "[p]remiums would go up for those buying in the traditional small-group market." competing against AHPs that offer less expensive and less comprehensive plans.
The average rates paid for health insurance plans are inversely related to the amount of coverage they provide, with Platinum plans being the most expensive and Bronze / Catastrophic plans being the cheapest. The following table shows the average rates a 21 year old would pay for individual health insurance based on plans in the different tiers. Older consumers would see their plans increase according to the age scale set by the federal guidelines.
Health insurance plans are separated into different metal tiers based on the proportion of health care costs the insurance plan is expected to cover. Catastrophic and Bronze plans cover the smallest proportion, having the highest deductibles, copays and coinsurance. On the other end of the spectrum, Platinum plans offer the greatest amount coverage, expected to cover 90% of all costs.
