Which coding standard is used to document procedures and services?

• A. ICD-10-CM
• B. CPT
• C. DSM-IV
• D. LOINC

Answer: (B)

Documents procedures and services with a standardized set of codes. CPT codes are the system created to describe the professional services clinicians provide—everything from office visits and surgeries to imaging and anesthesia. They provide precise, descriptive codes that make it clear what was done, which supports accurate billing and consistent communication across providers and payers. This focus on procedures and services is why CPT is the best fit here. In contrast, ICD-10-CM codes track diagnoses and conditions, DSM-IV covers psychiatric diagnoses, and LOINC codes identify laboratory tests and measurements.
