What type of coding pertains to laboratory and radiological procedures?

The correct designation for coding related to laboratory and radiological procedures falls under procedural coding. This type of coding system focuses on the procedures and services performed by healthcare providers, including diagnostic tests and medical interventions.

Procedural coding includes codes from systems like Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS), which encompass a wide range of services from routine lab tests to complex imaging studies. These codes are essential for billing and documentation, enabling healthcare providers to accurately capture the services rendered to patients and facilitate reimbursement from payers.

Diagnostic coding, on the other hand, is used to represent the medical diagnosis or reason for the visit and typically uses codes from the International Classification of Diseases (ICD) system. This is distinct from the procedural codes, which specifically categorize the clinical activities performed, such as laboratory and radiological procedures. Thus, procedural coding is the appropriate answer that pertains specifically to these types of services.
