In addition to patient and prescriber identifiers, which piece of information is essential for CSMD submission?

For the submission to the Controlled Substance Monitoring Database (CSMD), one of the critical pieces of information required is the estimated days' supply. This detail is vital because it reflects the dosage and duration of the prescription, which helps in monitoring the potential misuse and understanding the patient's treatment plan.

Having the estimated days' supply allows the monitoring system to track how long the patient is expected to use the medication and provides insight into the patient's adherence to the prescribed therapy. It also aids in identifying any patterns of over-prescribing or early refills, which are essential factors in assessing patient safety and the risk of substance abuse.

While other pieces of information like the pharmacy name, patient’s address, and medication expiration date may be relevant in certain contexts, the estimated days' supply specifically plays a crucial role in ensuring effective monitoring and assessment of controlled substances within the health care system.
