ICD (International Classification of Diseases) and CPT (Current Procedural Terminology) are coding systems used for what purpose?

• A. Billing for pharmacy supplies
• B. Classifying diagnoses and procedures
• C. Scheduling appointments
• D. Recording patient demographics

Answer: (B)

These coding systems are used to classify diagnoses and procedures. ICD codes standardize the naming and grouping of patient health problems and diseases, while CPT codes describe the specific medical services and procedures performed by clinicians. Together, they provide a common language for documenting what was diagnosed and what was done, which is essential for accurate billing, claims processing, and data reporting. They also support research, quality measurement, and health statistics. Pharmacy billing uses different codes (like NDC), scheduling and demographics data are tracked separately, so ICD and CPT focus on diagnoses and the procedures performed.
