Which of the following codes includes procedures awaiting determination?

The correct choice is B, G codes, as these are used primarily to identify certain types of procedures and services that are not fully classified under specific categories in the standard coding system. G codes are often utilized for procedures that are awaiting further determination regarding their coverage or reimbursement by payers.

These codes serve as a temporary solution, allowing providers to report services that may not yet have a definitive category. They are essential for maintaining accurate records while the final determination is pending. Thus, G codes play a critical role in the billing process, ensuring that healthcare providers can document and receive payment for services they render while awaiting further clarification on their coding.

A codes, H codes, and M codes pertain to different areas of medical billing and coding. A codes typically relate to ambulance services, H codes generally refer to services and items not covered elsewhere, and M codes are related to the management of certain medical conditions. Therefore, they do not specifically exist for procedures awaiting determination in the same way that G codes do.
