What do the letters "GN" represent in the HCPCS coding system?

The letters "GN" in the HCPCS coding system specifically refer to "Nurse Practitioner services." This designation is used to categorize and bill for the various services provided by nurse practitioners, who are advanced practice registered nurses that can perform many of the same functions as a physician, including diagnosing and treating medical conditions, prescribing medications, and managing patient care.

By using the "GN" code, healthcare providers ensure that nurse practitioner services are accurately represented for billing and reimbursement purposes. This coding helps distinguish the types of services provided and ensures that healthcare practitioners are properly compensated for their contributions to patient care.

The other options tend to describe other healthcare roles or services, but they do not align with the established HCPCS coding meanings and categories related to nurse practitioners. Therefore, the choice of "GN" as representing "Nurse Practitioner services" is the most accurate within the context of HCPCS coding.
