Which of the following is a characteristic of Tricare Standard and Extra?

Tricare Standard and Extra are characterized as fee-for-service plans, which means that beneficiaries can receive care from a wide range of providers who accept Tricare. Under this structure, beneficiaries have more flexibility in choosing their healthcare providers compared to managed care plans. They can obtain care from civilian providers without the need for referrals, and they also have the option to see specialists directly.

This configuration allows for a greater degree of autonomy in managing healthcare, as beneficiaries are able to visit any authorized provider and are billed for the services based on a percentage of the allowed amount, with the option to access care from both network and non-network providers. This aspect distinguishes these plans from others that might require pre-enrollment or network limitations, thus emphasizing the fee-for-service nature of Tricare Standard and Extra.
