Final answer:
Fee-for-service insurance is the coverage that allows for case-by-case patient visits, reimbursing providers based on service costs.
Step-by-step explanation:
The type of insurance coverage that allows patients to be seen on a case-by-case basis, rather than as part of a regular health plan, is fee-for-service insurance. In this system, medical care providers are reimbursed according to the cost of services they provide, without a predefined limit on the amount of services one can use. This contrasts with health maintenance organizations (HMOs), where providers are paid a fixed amount per person enrolled, regardless of how many services each person uses.
The type of insurance coverage that allows patients to be seen on a case-by-case basis is fee-for-service insurance. In a fee-for-service health financing system, medical care providers are paid according to the services they provide. This means that patients can access healthcare services as needed, without being limited to a specific network of providers or having to seek approval from an insurance company.
