Final answer:
The correct understanding of the non-par Medicare allowed fee schedule is that non-participating providers can charge up to 15% over the Medicare-approved amount, known as the limiting charge, not a flat value of "115."
Step-by-step explanation:
The question pertains to the non-Participating (non-Par) Medicare allowed fee schedule, which concerns the billing practices and allowable charges for healthcare providers who choose not to enter into an agreement with Medicare. Out of the options provided, the statement that the non-Par limiting charge is 115 is not fully accurate without context.
It is important to mention that the non-Par provider can bill the patient the difference up to the limiting charge over the Medicare approved amount, which could be 115% of the Medicare fee schedule. Therefore, the initial statement needs to be revised to reflect the percentage rather than a numeric value. The correct understanding is that the non-participating provider can charge up to 15% more than the Medicare fee schedule for services rendered. This practice, as well as the economic implications of Medicare policies, has indeed impacted the cost of medical care over time.
