CMS rules include determinations of what concepts?

• A. Medically Necessary Designations
• B. NPI Requirements
• C. Medically Necessary / Usual and Customary
• D. ICD Coding Guidelines

Answer: (C)

Medical necessity and usual and customary charges are what CMS uses to decide coverage and payment. Medical necessity means the service or supply is reasonable and necessary for diagnosing or treating a patient’s condition and appropriate for their circumstances. Usual and customary refers to the typical amount charged by providers in the local area for the same service. Together, these determinations drive whether CMS will pay and at what rate. ICD coding guidelines and NPI requirements are important for billing, but they serve different roles—coding ensures accurate claims and NPI identifies the provider—rather than being the CMS determinations that control payment. Medically Necessary Designations aren’t a standard CMS term for reimbursement decisions.
