Final answer:
A physician's order for services under Medicare includes necessary medical services, but does not typically cover eyeglasses and eye care unless under specific conditions. Concepts like moral hazard, adverse selection, and fee-for-service are related to health care economics, rather than details in a physician's order.
Step-by-step explanation:
Under Medicare regulations, a valid physician's order for services must include several important pieces of information. However, not all elements of medical care will be included in a physician's order. For instance, the order will specify the necessary medical services, like the need for prescription drugs, medical supplies, and hospital services. However, items such as eyeglasses and eye care, which are mentioned in the concept of medical care in general, are usually not included in a Medicare physician's order for services since Medicare typically does not cover these unless they are after cataract surgery or for some other qualifying condition. Furthermore, medical care elements like moral hazard, adverse selection, and financial terms like fee-for-service are concepts related to health economics and insurance design, which are not part of a physician's order itself but rather describe the broader health care system and payment models, including Medicare and Medicaid. The Patient Protection and Affordable Care Act (ACA or Obamacare) also impacts the structure of this system but is not directly referenced in a physician's order.
