Which code category is used to describe procedures and services?

• A. CPT codes
• B. ICD 10 codes
• C. Coinsurance
• D. Deductible

Answer: (A)

Procedural and service descriptions in medical billing are captured using CPT codes. The CPT system, or Current Procedural Terminology, is designed specifically to label the exact procedures and services performed during a patient visit, including tests, treatments, surgeries, and evaluation and management activities. These codes enable clear communication about what was done and help insurers process claims. ICD-10 codes, on the other hand, describe the patient’s diagnoses or the reason for the encounter. Coinsurance and deductible refer to patient cost-sharing in insurance, not to how services are coded.
