ICD-10-CM codes on a claim are used to report which information?

• A. Diagnoses
• B. Procedures
• C. Medications
• D. Provider addresses

Answer: (A)

ICD-10-CM codes describe the patient’s diagnoses and health problems for a visit. They justify medical necessity and show why the services were provided, tying the care to the specific condition. Procedures and services are reported with CPT/HCPCS codes, not ICD-10-CM; medications use separate coding systems like NDC, and provider addresses aren’t reported with ICD-10-CM. So the codes on a claim report the diagnoses.
