In health insurance terms, what does "network" refer to?

In health insurance, "network" specifically refers to a group of healthcare providers and facilities that have an agreement with an insurance company to provide services at negotiated rates. This arrangement typically allows members who use in-network providers to receive lower out-of-pocket costs, as the providers accept pre-established payment terms set by the insurance provider. The concept of a network is fundamental in managing healthcare costs and ensuring that patients have access to a range of services while controlling expenses for both the insurer and the insured.

By offering services at negotiated rates, networks help to facilitate coordinated care and often result in better health outcomes for patients, as the insurance companies work strategically with their contracted providers. The other options do not accurately define the concept in the context of health insurance. For instance, a group of healthcare providers and facilities that offer services at standard rates does not encompass the specificity of negotiated agreements that characterize health insurance networks.
