A DEA diversion investigator interview often starts with a phone call or a knock at the pharmacy counter, sometimes tied to an open inventory reconciliation review already underway. The investigator questions technicians and pharmacists separately, and what each says can shape whether the registrant faces a routine finding or a referral for prosecution. Interviews of this kind are generally voluntary, though few staff know that going in. Pharmacists-in-charge who prepare their team on process, not on answers, before an investigator arrives stand in a materially stronger position than those who improvise.
What a Diversion Investigator Asks Pharmacy Staff
A diversion investigator's questions track the dispensing record, not general pharmacy operations. Technicians are commonly asked who has access to a specific login or override code, how a fill was counted and verified, and whether a physical count matched the perpetual inventory on a given date. Pharmacists are asked about clinical judgment: why a prescription was filled despite a red flag, how a prescriber's controlled-substance pattern was evaluated, and what the pharmacy's standard operating procedure required before dispensing. The investigator typically already holds dispensing logs, ordering records, and DEA Form 222 or CSOS data before the interview begins, so vague or inconsistent answers stand out against a paper trail the investigator can already see.
Interviews Are Voluntary, With Limits
A diversion investigator's authority to inspect a registrant's premises and records under 21 CFR Part 1316 is separate from any authority to compel an employee to answer questions on the spot. A technician or pharmacist approached for an interview is generally not obligated to respond immediately. Staff may ask to reschedule, request that counsel be present, or decline to answer a question outside their personal knowledge. Investigators typically prefer one-on-one interviews, away from other staff, though an employee can still ask for a moment to call the pharmacy's attorney first. This does not limit a lawful inspection of the premises. It only governs how an individual answers questions about personal conduct.
The pharmacy's attorney represents the registration, not any single employee, and the moment those interests diverge, the employee needs counsel of their own.
Counsel for the Business Is Not Counsel for the Employee
When a pharmacy retains counsel to respond to a diversion investigation, that attorney represents the registrant, not any single technician or pharmacist as an individual. In most interviews the registrant's and the employee's interests point the same direction, and counsel can advise both without conflict. That changes once an investigator focuses on one employee's specific conduct: a particular override, a specific set of fills, a personal relationship with a prescriber. Once the registrant's interest in preserving its registration and an employee's interest in avoiding personal exposure diverge, the registrant's counsel has to say so, and that employee should retain separate counsel before the next interview.
Preparing Staff, and What to Do If an Interview Already Happened
Preparing staff means explaining what to expect, not what to say: who may be present, that the interview is voluntary, and that a factual answer limited to personal knowledge is always right. Rehearsing a preferred version of a fill or discrepancy is coaching, not preparation, and it risks an obstruction problem on top of whatever the review finds; a false statement to a federal investigator, even one meant to be helpful, is itself a federal crime under 18 U.S.C. § 1001. When staff have already answered questions without counsel present, an owner should not ask them to correct or walk back what was said outside a documented process. The better first step is a privileged debrief with counsel on what was asked, what records the investigator already had, and whether the questions focused on one employee or the pharmacy's practices generally.
Why Early Legal Counsel Is Critical
It is critical that pharmacies retain experienced healthcare defense counsel promptly once a DEA diversion investigator asks to interview staff, whether or not a formal audit notice has been issued. Early legal intervention can protect both the registrant and individual employees, keep interview responses factual and within each witness's personal knowledge, avoid inadvertent admissions, and preserve defenses before a routine interview becomes an inventory reconciliation dispute or a registration action. Delaying legal representation can significantly affect the outcome of the review and expose both the pharmacy and its staff to unnecessary risk.
