The distinguishing aspect of the CPT (Current Procedural Terminology) code in healthcare billing is that it relates to procedures performed during patient visits. CPT codes provide a standardized way to document and report medical, surgical, and diagnostic services and procedures to various entities such as insurance companies and healthcare providers. This standardization is crucial for communication across the healthcare system, ensuring that all parties have a clear understanding of what services were rendered.

While identifying diagnoses is an important function in healthcare, that role is primarily fulfilled by ICD (International Classification of Diseases) codes, not CPT codes. Additionally, CPT codes are applicable to a wide range of services, not just laboratory services, which further supports the idea that they relate broadly to procedures. Lastly, CPT codes are used by a variety of stakeholders in healthcare, including healthcare providers, not solely by insurance companies.
