DEA Diversion Complaints & Inquiries Attorney
Healthcare professionals and entities authorized to handle controlled substances are subject to strict oversight by the Drug Enforcement Administration (DEA). When the DEA suspects that a provider has failed to comply with the Controlled Substances Act or related regulations, it may initiate a diversion investigation. These inquiries can quickly become serious enforcement actions, threatening a provider’s DEA registration, licensure, reputation, and even their liberty. At Aaron L. Wiley, P.C., we represent clients facing DEA diversion complaints with clarity, discretion, and decades of experience on both sides of government enforcement.

What Is DEA Diversion?
DEA diversion occurs when controlled substances are allegedly transferred, prescribed, or dispensed for purposes outside the scope of legitimate medical practice. Common examples include prescribing opioids without proper medical justification, failure to maintain accurate records, inadequate security of medication storage, or unauthorized staff accessing controlled substances. The DEA may initiate an inquiry based on audits, patient complaints, pharmacy records, or coordination with state medical boards and law enforcement agencies.
Once a complaint is received or suspicion arises, the DEA may issue an administrative subpoena, conduct an inspection, or send diversion investigators to interview staff and review records. In some cases, criminal charges may follow, particularly when the agency believes there has been willful misconduct or fraud.
DEA investigators frequently start with data, not a single complaint. The Automated Reports and Consolidated Orders System of the agency tracks controlled substance transactions from manufacturing through distribution. When the volume of prescriptions from a provider exceeds the regional average for a particular drug class, this becomes the starting point for an investigation into diversion. Investigators then build on this information, reviewing patient records and comparing prescribing practices with what a typical practitioner in the same field would do.

Common Triggers for a DEA Diversion Investigation
Certain patterns attract DEA attention more quickly than others. None of these patterns guarantee an investigation, nor do they prove wrongdoing alone. However, they are patterns that appear repeatedly in orders to show cause and criminal indictments.
- High percentages of patients paying out-of-pocket for opioid prescriptions, when insurance would typically cover the visit.
- Prescribing the same combination of medications – an opioid, benzodiazepine, and muscle relaxant – to a significant portion of a practice’s patients, sometimes referred to as the “trinity.”
- Patients travelling long distances to see one prescriber, when closer options are available.
- Missing or altered patient records, especially those related to pain management.
- Discrepancies between pharmacy dispensing records and what distributors report supplying.
- Staff turnover or complaints from former employees regarding pressure to quickly fill prescriptions.
A single item on this list rarely triggers a full investigation. However, several together, especially when paired with a patient complaint or an overdose death, usually do.
Responding to DEA Inquiries
Early legal representation is essential when responding to DEA inquiries. The manner in which a healthcare provider or business responds to the DEA can significantly impact the trajectory of the case. Providing incomplete or inaccurate information, failing to respond appropriately, or making unguarded statements can result in further investigation or even the initiation of enforcement proceedings.
At Aaron L. Wiley, P.C., we assist clients in responding to subpoenas, preparing for interviews or inspections, and ensuring that communications with the DEA are clear, accurate, and legally sound. We also conduct internal reviews to identify and address potential weaknesses in compliance procedures, recordkeeping, and prescribing protocols.
Do not sign anything presented by the DEA during an unannounced visit without reading it first, and do not agree to a recorded interview without speaking with counsel first. Investigators may ask you to surrender your registration voluntarily. Voluntarily surrendering rarely helps your case, and makes re-application much harder later. A brief delay to call a lawyer is not obstructive.
Potential Penalties for DEA Diversion Violations
The consequences of a diversions finding extend beyond the loss of registration.
Civil penalties under the Controlled Substances Act can run into tens of thousands of dollars per violation, and the DEA counts each improperly filled prescription or each inaccurate record entry separately. A pattern of record-keeping problems can lead to civil exposure that exceeds the value of the prescriptions in question.
Criminal exposure is a more serious risk. Distribution of a controlled substance outside the usual course of professional practice may be charged under Section 841 of the US Code, the same law used against street-level drug trafficking. Federal sentences are scaled according to the schedule and amount of drugs involved, and can last for years, not months.
A diversion finding also travels. The DEA routinely notifies state medical, dental, and pharmacy boards about adverse actions, which can trigger separate licensing investigations. Losing DEA registration and state licenses at the same time is common, rather than an exception.
Protecting Your DEA Registration and Practice
Loss of DEA registration can effectively end a provider’s ability to treat patients or operate their practice. That is why it is critical to mount a proactive, strategic response to any diversion-related inquiry. Whether the issue involves a single prescribing decision or a broader audit of your controlled substance handling procedures, our firm works to protect your registration and limit the scope of enforcement actions.
If the matter escalates to an administrative hearing or criminal investigation, Aaron L. Wiley provides skilled representation at every stage. His background as a federal prosecutor gives him insight into how these cases are charged and what arguments are most effective in challenging government findings.
A corrective action plan submitted early, before a formal order to show cause, can sometimes resolve compliance gaps without escalating to suspension. The window for this closes quickly. Once the order has been served, the responsibility shifts to demonstrating why the DEA’s findings are wrong.
