Each prescription for a controlled substance requires what type of registration number?

The registration number required for each prescription for a controlled substance is the DEA registration number. This is mandated by the Drug Enforcement Administration (DEA), which regulates the prescription and distribution of controlled substances in the United States.

The DEA registration number is unique to each prescriber and is used to ensure that the prescriber is authorized to dispense controlled substances. This number must be included on all prescriptions for controlled substances to establish legality and to allow for tracking and monitoring by regulatory bodies. It holds vital importance in preventing drug abuse and ensuring compliance with federal laws.

In contrast, other options like the state registration number pertains to state licensing requirements and does not have the specific authority related to controlled substances that the DEA number does. Medicare numbers are used for billing and eligibility verification within the Medicare program, and insurance registration numbers are for insurance claims processing. Neither of these options is specific to the authorization to prescribe controlled substances.
