The coding system that primarily addresses professional fees for physician services is CPT coding. This system, which stands for Current Procedural Terminology, is specifically designed to provide a uniform language for describing medical, surgical, and diagnostic services and procedures performed by healthcare providers. It allows for the accurate reporting and billing of physician services and ensures that providers can be reimbursed appropriately for their work.

CPT codes are used extensively by physicians and healthcare practitioners to detail the services rendered during patient visits, thus being integral to the billing process. Each code within the system reflects a specific service or procedure, making it essential for ensuring correct and efficient communication between healthcare providers and insurers.

Other coding systems serve different purposes; for instance, ICD coding is primarily focused on the classification of diseases and health-related problems, while HCPCS coding includes codes for services, equipment, and supplies not covered by CPT. DRG coding pertains to diagnoses related groups, which influence hospital payment systems rather than individual physician billing.
