For how long must CSOS records be maintained?

In the context of Controlled Substance Ordering System (CSOS) records, the requirement is to maintain these records for a period of two years from the date of the document. This regulation ensures that there is sufficient time for auditing and regulatory compliance checks by the Drug Enforcement Administration (DEA) or other relevant authorities.

Maintaining CSOS records for two years supports effective monitoring of controlled substances, helping to prevent diversion and misuse. The two-year requirement aligns with various regulatory frameworks that emphasize accountability and traceability in the handling of controlled substances.

Thus, the choice indicating a two-year retention period aligns with federal regulations regarding the management of records related to controlled substances, confirming its accuracy in this context.
