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.

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.

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.
