DEA Form 106
What to Do When Controlled Substances Go Missing
A missing controlled substance is not just an inventory issue. Federal rules require prompt DEA notice for theft or significant loss, and the clinic should preserve the facts that explain the decision.
Verified · 2026-07-06The federal reporting trigger
A DEA registrant must notify the DEA Field Division Office in writing of the theft or significant loss of any controlled substances within one business day of discovery. 1
The registrant must also file a complete and accurate DEA Form 106 through DEA's Diversion Control Division secure network application. 1
The same security rule restricts certain employees with controlled-substance access based on prior felony drug convictions or prior DEA-registration actions. 1
Significant loss is a judgment call
DEA guidance says small losses may be reported if the registrant determines they are significant, and a pattern of seemingly insignificant losses should always be considered significant. 2
DEA Form 106 should not be used to explain minor inventory discrepancies or to balance the books. 2
Breakage and spillage that are not theft or significant loss are recorded under the controlled-substance record rules rather than converted into a Form 106 event. 3
What to pull before filing
Pull the relevant per-drug log, receiving invoice, dispensing/administering entries, wastage records, access list, and last inventory count. 3 4
Do not assume the DEA report is the only required notice; check the state overlay for the practice location before the incident file is closed. 1
