What is a CPT code?

• A. A diagnostic code
• B. Used only for inpatient services
• C. Represents the professional services provided by a clinician; five-digit number
• D. A global surgical code

Answer: (C)

CPT codes are the standardized way doctors and other clinicians report the procedures and services they provide for billing and administrative purposes. They specifically describe the work done by the professional, not the patient’s diagnosis. The familiar format is five-digit numeric codes, which covers a wide range of services from office visits to imaging and procedures. This makes CPT distinct from diagnostic codes (which describe why the service was needed) and explains why the statement that CPT codes represent the professional services provided by a clinician and are five-digit numbers is the best description.
