Does medically efficient has the same contractual meaning medically necessary?

No, "medically efficient" and "medically necessary" do not have the same contractual meaning. "Medically necessary" typically refers to services or treatments that are appropriate and required for a patient's condition, as determined by accepted medical standards. In contrast, "medically efficient" may imply that a treatment is effective in achieving the desired health outcomes while minimizing costs or resource use, which could vary based on different considerations. Always refer to specific contractual definitions for clarity.
