Final answer:
Modifiers in health care affect health care premiums, the explanation of charges, and code selection, addressing issues like adverse selection by influencing how insurance is priced and services are billed.
Step-by-step explanation:
Modifiers in the context of health care and insurance primarily affect the following areas:
- Health care premiums - Modifiers can adjust the cost of insurance premiums based on an individual's risk factors.
- Date of treatment provided - Modifications might specify certain dates for which particular coverage applies or care was given.
- Explanation for charges - Modifiers can be used to provide a rationale for charges that are higher or lower than standard for a specific code, reflecting the complexity or simplicity of services provided.
- Code selection - Modifiers can influence the selection of billing codes, which could reflect additional services or modifiers to standard procedures.
Due to adverse selection, insurance companies face risks when individuals have better knowledge of their health risks. If the insurance company attempts to charge an actuarially fair premium generalized for the entire group without considering individual risk, it may end up losing low-risk clients who deem the premium too high, while attracting high-risk clients who find the premium favorable.
This relates to the concept of moral hazard, where the behavior of the insured party may change after obtaining insurance coverage due to a lack of incentive to avoid risks. The individual mandate provision of the Patient Protection and Affordable Care Act (ACA or Obamacare), as described in Option c of the self-check question, requires everyone to have insurance or pay a penalty, which helps mitigate adverse selection and moral hazard by ensuring a mix of low and high-risk participants.
