CPT is used for insurance claims; which of the following best describes 'CPT' usage?

• A. Diagnoses coding only
• B. Procedure and service coding for claims
• C. Referral management
• D. Patient scheduling

Answer: (B)

CPT codes are used to describe the procedures and services provided during a patient encounter so insurers can determine reimbursement. They specify what was done—surgical procedures, tests, anesthesia, evaluation and management services, and other procedures—on the claim form. Diagnoses, which justify why the service was needed, are coded separately with ICD-10-CM, not CPT. Administrative tasks like referral management or patient scheduling aren’t described by CPT codes. Hence, CPT’s role is to code the actual procedures and services for billing, making it the best match for describing CPT usage.
