Which statement about ICD-10 is true?

• A. It contains diagnosis codes.
• B. It contains medication codes
• C. It contains physician licensing guidelines
• D. It contains CPT codes

Answer: (A)

ICD-10 is the coding system used to classify diseases and other health conditions for medical records and billing, and it includes diagnosis codes. This is the primary purpose of ICD-10-CM in clinical documentation. Medications are coded with separate systems like the National Drug Code (NDC) or RxNorm, not ICD-10. Licensing guidelines for physicians aren’t part of ICD-10 either; those are set by regulatory boards and not a medical coding system. CPT codes cover procedures and services and are distinct from ICD-10. So the statement that ICD-10 contains diagnosis codes is the accurate one.
