Final answer:
Healthcare benefits are well-defined with stipulations and coverage details in the benefit plan. Healthcare costs and variables can vary, but plans like Medicare do have structured payments. A difference between fee-for-service and HMOs is the payment structure, which impacts provider incentives.
Step-by-step explanation:
The correct answer to which of the following is true of healthcare benefits is 'd. The benefits are well-defined in healthcare benefits.' Healthcare benefits typically come with specific stipulations and coverage details outlined in the benefit plan. Unfortunately, healthcare benefits are not always predictable (variables in healthcare benefits are generally predictable) as individual health needs and treatment costs can vary widely. Healthcare plans may be funded—either publicly (e.g., Medicare for people over sixty-five) or privately. Payments such as premiums, deductibles, copayments, and coinsurance can be part of a healthcare benefit plan. These payments can be structured in various ways, such as monthly premiums for Part B of Medicare. Finally, a key difference between a fee-for-service plan and an HMO is that the latter pays providers a fixed amount per patient, which incentivizes cost control, as opposed to payment per service rendered.
