DEA Form 106: Reporting Theft or Significant Loss

A pharmacy that discovers a break-in, an unexplained shortfall in a controlled substance count, or a missing bottle of oxycodone is on the clock the moment the loss is confirmed. Federal law requires every DEA registrant, pharmacies included, to report a theft or significant loss of controlled substances to DEA, first with a same-day written notice and then with a completed DEA Form 106. Miss the deadline or misjudge what counts as significant, and the pharmacy has created a second problem on top of the loss itself: a reporting failure that can become the basis for its own DEA registration action.

The Two-Step Reporting Requirement

21 CFR 1301.76(b) requires a registrant to notify its local DEA Diversion Field Office in writing within one business day of discovering a theft or significant loss of controlled substances. That notice starts the clock on a second, more detailed obligation. Under 21 CFR 1301.74(c), the registrant must complete and file DEA Form 106 within 45 calendar days of discovery. Since July 2023, the DEA Diversion Control Division has accepted Form 106 only through its secure online reporting system; paper filings are no longer accepted. The one-business-day notice exists so DEA, and where relevant state or local law enforcement, has the chance to participate in the investigation while the evidence is fresh, not after the pharmacy has already reconstructed its own version of events.

What Counts as a Significant Loss

Every theft of a controlled substance gets reported, regardless of quantity. A loss is different: DEA sets no numeric threshold for what makes a loss significant, and leaves that judgment to the registrant in the first instance. DEA's guidance points to six factors: the quantity lost relative to the type of business, the specific controlled substances involved, whether the loss can be tied to particular individuals with access, whether the loss fits a pattern or looks random, whether the missing drugs are attractive diversion targets, and local diversion trends. A pharmacist-in-charge who treats a small, recurring discrepancy as immaterial because no single count looks alarming is applying the wrong test. DEA reads the pattern, not the single event, and an accurate inventory reconciliation is what surfaces the pattern in the first place.

The Investigation That Follows

A filed Form 106 does not close the file. DEA Diversion Control Division reviews the report against the registrant's dispensing and ordering history, and a pattern of losses tied to specific staff, specific shifts, or specific drugs can open a diversion investigation independent of the theft itself. Because maintaining effective controls against diversion is a condition of every DEA registration under 21 U.S.C. § 823(h), a Form 106 that exposes weak security, sloppy recordkeeping, or a missing suspicious order monitoring program becomes evidence against the registration, not just a record of the loss. Where DEA concludes the deficiency creates an imminent danger to public health or safety, it can issue an immediate suspension order before any hearing. Short of that, the more common path is a DEA order to show cause, the administrative proceeding where DEA lays out why a registration should be restricted, suspended, or revoked.

A DEA Form 106 filed to report a loss can become the exhibit DEA uses to question the registration itself.

Why Early Legal Counsel Is Critical

It is critical that pharmacies promptly retain experienced healthcare defense counsel once a theft or significant loss is discovered, not after DEA Form 106 is filed. Early legal intervention shapes what the preliminary notice and the Form 106 say, preserves the recordkeeping and security record DEA will review, and lets counsel communicate with the Diversion Field Office on the pharmacy's behalf. Delaying representation until a show cause order arrives can mean defending decisions that were already made without legal input.
