Final answer:
If 'incident-to' billing criteria are met, nurse practitioner visits can be reimbursed at 100% of the physician rate by Medicare Part B.
Step-by-step explanation:
In the context of Medicare billing for services provided by a nurse practitioner, when the "incident-to" billing criteria are met, the anticipated reimbursement is at 100% of the physician rate. This indicates that the nurse practitioner's services, when performed under the direct supervision of a physician and fulfilling all other 'incident-to' criteria, are billed as if the physician provided the services directly. Such an arrangement allows for full reimbursement from Medicare Part B, which is significant given that Part B covers health-care costs such as physician services, medical tests, and outpatient visits. For the patient, Part B requires a monthly fee, deductibles, and copayments, with the government contributing around three-quarters of the overall costs.
