Which code type is used to describe the diagnosis?

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

Answer: (A)

Diagnoses are described using standardized codes, and the code type for the diagnosis is ICD-10-CM. This system (International Classification of Diseases, 10th Revision, Clinical Modification) provides specific codes for diseases, symptoms, and conditions so clinicians and insurers can clearly communicate what a patient has. These codes appear in the patient’s medical record and on claims to describe the reason for the visit.

CPT codes, on the other hand, describe the procedures or services performed (like a spinal adjustment, imaging, or other treatments) rather than the diagnosis itself. Copayments and deductibles are financial terms related to patient payment responsibility, not coding. So the diagnosis is described with ICD-10-CM codes.
