What is a gp modifier?

A GP modifier is a Medicare billing modifier used to identify primary care services provided by physicians and other healthcare practitioners. This modifier is used to indicate that the services provided are primary care services that are essential for the ongoing healthcare of the patient. The GP modifier is added to the Healthcare Common Procedure Coding System (HCPCS) code when the service is provided by a physician or qualified healthcare professional in a primary care setting. The GP modifier helps ensure that primary care providers are properly reimbursed for their services. It also helps to promote the continuity of care and preventive healthcare. The use of the GP modifier is required for reimbursement of certain services, such as annual wellness visits and preventive services.
