Which statement best describes the data elements typically required on a CMS professional claim?

• A. The full set of: Patient demographics, dates of service, provider NPI, place of service, CPT/HCPCS codes, modifiers, diagnosis codes (ICD-10-CM), and charge/allowed amounts
• B. CPT/HCPCS codes, modifiers, diagnosis codes (ICD-10-CM), and charge/allowed amounts
• C. Patient demographics, dates of service, provider NPI, and place of service
• D. Diagnosis codes (ICD-10-CM) and CPT/HCPCS codes only

Answer: (A)

Completeness of the data elements required on a CMS professional claim is essential for accurate identification, adjudication, and payment. The best answer includes all of these: patient demographics to identify and match the patient, dates of service to show when the service occurred, the provider NPI to identify who performed the service, place of service to indicate the setting, CPT/HCPCS codes (with any modifiers) to describe the services rendered, ICD-10-CM diagnosis codes to justify medical necessity, and the charge/allowed amounts to determine the reimbursement. This full set ensures the claim can be correctly processed by the payer, linking the patient, provider, service, and financials in a compliant manner and reducing the chance of rejection or delay. The other options leave out one or more of these essential elements, making the claim incomplete and harder to adjudicate.
