Under the Medicare limiting charges clause, nonPAR providers may not charge a Medicare patient more than _____ percent of the fee listed in the nonPAR MFS.

The correct answer is 115 percent. Under the Medicare limiting charges clause, non-participating (nonPAR) providers are allowed to charge Medicare patients a fee that cannot exceed 115 percent of the Medicare fee schedule for the specific service provided. This is established by Medicare guidelines to protect patients from excessive charges while ensuring that providers can operate in a reasonable manner.

This limitation helps maintain a level of fairness and affordability for patients who may need to seek care from nonPAR providers, as these providers do not have a contract with Medicare and can thus charge more than participating providers. However, by capping their fees at 115 percent of the standard fee schedule, Medicare ensures that patients have some protection against inflated costs.
