Final answer:
The correct term for a list of contracted doctors and hospitals within an insurance plan is a Provider Network. This network is part of the framework agreed upon between healthcare providers and an insurance company.
Step-by-step explanation:
The list of doctors and hospitals that a plan contracts with to provide medical care to its members is called a Provider Network. Medical providers within this network agree to the insurance companies' terms and fees, offering services at negotiated rates to members of the insurance plan. This network is different from concepts like deductible, which is how much the policyholder pays out-of-pocket before the insurance kicks in; copayment, which is a fixed fee for a service; and coinsurance, which is the percentage of costs shared by the policyholder and insurance.
