For CSMD submission, which of the following must be reported concerning the patient?

The correct choice regarding the requirements for Controlled Substance Monitoring Database (CSMD) submission is the patient identifier. This is essential for accurately tracking the prescription history of individuals across pharmacy systems. The patient identifier may include information such as a unique identification number or other personal identifiers that ensure the correct association of prescribed controlled substances with the right patient. This level of identification is critical for the prevention of prescription drug abuse and ensures that healthcare providers can access comprehensive records of a patient's controlled substance use.

While the other options include important information, they do not specifically satisfy the criteria needed for CSMD submission. For example, full name and age provide identifying information but are not as unique as a patient identifier. Similarly, details about insurance plans or medical history, while relevant in some contexts, are not typically mandated for CSMD reporting. The primary focus in CSMD submissions is to maintain a clear and unique linkage of prescriptions to the individuals receiving them to facilitate monitoring and prevention efforts.
