What does medical coding involve?

• A. Codes used for diagnoses AND procedures given to a patient
• B. Codes used for medications only
• C. Billing codes only
• D. Lab tests only

Answer: (A)

Medical coding is the process of turning what happened during a patient encounter into standardized codes used in health records, billing, and data analysis. It encompasses codes for both diagnoses and procedures—the diagnosis codes (ICD-10-CM) describe what conditions the patient has, and the procedure codes (CPT/HCPCS) describe the services or interventions performed. This dual scope is what makes the correct choice best: it reflects the full range of coding needed to represent patient care, not just medications, billing codes, or lab tests treated in isolation. Medications, billing-specific codes, and lab test identifiers exist in related systems, but the central task of medical coding is to capture both diagnosed conditions and the procedures or services provided.
