What is the second division in the CPT coding system?

In the CPT coding system, the correct answer is that the second division is known as a subsection. The CPT (Current Procedural Terminology) coding system is organized hierarchically, which allows coders to easily locate and apply codes.

To clarify the structure, the first division is the section, which groups codes based on the type of service provided—such as Evaluation and Management, Surgery, or Radiology. Within these sections, the subsections further categorize codes into more specific areas, allowing for precise coding of procedures and services. For example, within the Surgery section, there may be subsections for different body systems or types of surgical procedures.

Understanding this hierarchy is essential for effective coding, as it ensures that the correct codes are utilized for billing and reimbursement purposes. Each subsection can contain codes that share similar characteristics, thereby making it easier for healthcare providers to document and code services accurately.
