What identifier should be used for CSMD if a patient refuses to provide their SSN, driver's license number, or telephone number?

When a patient refuses to provide their Social Security Number (SSN), driver's license number, or telephone number for the purpose of the Controlled Substance Monitoring Database (CSMD), the correct identifier to use is the placeholder number 999-99-9999. This number serves as a unique identifier that allows the patient’s information to be submitted into the CSMD system without revealing their personal details.

Utilizing this specific placeholder is in accordance with privacy and regulatory standards that seek to maintain patient confidentiality while also ensuring compliance with reporting requirements. It signals to the system that there is no actual personal identifier supplied by the patient.

The other options provided, such as 555-55-5555, 000-00-0000, and 123-45-6789, do not have the same established use as a placeholder specifically recognized in this context and could potentially lead to misinformation or misuse in the system. Therefore, using 999-99-9999 is the appropriate action to take when the patient does not provide typical identifying information while trying to maintain compliance with pharmacy laws.
