Overview

Has the DEA Conducted an Inspection at Your Pharmacy, Practice, or Healthcare Facility?

A DEA inspection can rapidly escalate from a routine review into an enforcement matter that jeopardizes a registrant’s ability to prescribe, dispense, administer, distribute, or otherwise handle controlled substances. Investigators may begin with inventories, DEA Forms, prescription records, security measures, or dispensing practices, but perceived discrepancies can lead to allegations of recordkeeping violations, unresolved red flags, diversion, an Immediate Suspension Order, or proceedings to revoke the DEA registration.

Our DEA defense attorneys represent pharmacies, physicians, clinics, and other DEA registrants in DEA inspections, diversion investigations, Orders to Show Cause, Immediate Suspension Orders, and other DEA proceedings. We act quickly to assess the Agency’s concerns, protect the record, and develop a strategic response designed to preserve your DEA registration and your ability to prescribe, dispense, administer, distribute, or otherwise handle controlled substances.

Health Law Alliance intervenes early to take control of the DEA inspection or investigation before it escalates. Our attorneys manage communications with DEA personnel, assess the scope and legal consequences of inspection and/or document demands, review records before production where appropriate, and challenge the factual basis for alleged inventory shortages, recordkeeping deficiencies, prescribing concerns, and diversion allegations.

When DEA seeks to restrict, suspend, deny, or revoke a registration, our experienced healthcare defense attorneys represent registrants in Orders to Show Cause, Immediate Suspension Order proceedings, and related litigation as well as state board actions. We build a focused defense alongside a practical corrective-action plan designed to address legitimate concerns, protect the practice’s ability to handle controlled substances, and minimize the consequences of alleged violations of the Controlled Substances Act, DEA regulations, and applicable state laws.

Health Law Alliance’s DEA defense team is led by Diana Yastrovskaya and Anthony Mahajan and works closely with Nancy Coffey, a former DEA Diversion Program Manager with over 30 years of experience. Ms. Coffey brings an Agency-informed understanding of DEA policy, DEA inspection practices, and DEA’s compliance requirements developed through years of direct responsibility within the DEA. Her perspective helps our DEA defense team anticipate the issues DEA investigators are likely to examine, assess the significance of alleged deficiencies, and develop a focused defense and compliance strategy.

Notably, a DEA inspection or investigation rarely exists in isolation. What begins as a review of controlled-substance records can jeopardize a provider’s DEA registration and professional license, trigger parallel licensing board proceedings, including Board of Pharmacy proceedings and, in more serious cases, lead to a DEA criminal or civil investigation. With those collateral consequences in view from the outset, our DEA defense team evaluates every document production, statement, corrective-action proposal, and potential resolution across all potential matters, so that a response intended to resolve one issue does not create unnecessary exposure in another forum.

Strategic DEA Defense From Inspection Through Resolution

From the first inspection notice through any resulting enforcement action, we assess the DEA’s concerns, scrutinize the evidence, and evaluate the consequences of every response, production, corrective-action proposal, and potential agreement before advising on a strategic path forward.

DEA Inspection Checklist

HLA’s Guide for DEA Inspections & Investigations

A DEA inspection is a high-stakes regulatory event, not a routine audit. The manner in which a pharmacy, healthcare practice, clinic, or other DEA registrant responds in the first hours can shape the Agency’s view of the matter and affect the registrant’s DEA registration, professional license, and ability to continue handling controlled substances.

This checklist identifies the ten immediate steps HLA’s DEA defense team recommends healthcare providers take to preserve the record, protect the registrant’s rights, manage the inspection lawfully and professionally, and prevent avoidable issues from escalating into a DEA enforcement action.

DEA Inspection Response Checklist: 10 Immediate Steps

01

Remain calm and immediately notify counsel

Contact experienced DEA counsel at the outset. Do not make assumptions, admissions, or informal explanations before the scope of the inspection is understood.

02

Confirm the inspectors’ identities and authority

Request and document each investigator’s name, agency, badge number, and contact information. Determine whether the inspection is administrative, investigative, or pursuant to a warrant.

03

Review the legal basis and scope of the inspection

Confirm whether DEA is relying on a signed administrative inspection warrant, voluntary consent, a valid DEA inspection notice, or another asserted authority. Do not consent to an expanded search without consulting counsel.

04

Designate one point of contact

Assign a knowledgeable representative, ideally the Pharmacist-in-Charge, practice manager, compliance officer, or owner, to coordinate communications, accompany investigators, and maintain an accurate record of all requests.

05

Maintain a contemporaneous inspection log

Record the date and time of arrival, each investigator present, every area inspected, records requested or reviewed, questions asked, statements made, and any documents or items copied, photographed, or seized.

06

Preserve all relevant records and communications

Immediately preserve controlled-substance records, inventories, invoices, dispensing logs, prescription files, electronic data, security footage, policies, employee communications, and related materials. Do not alter, destroy, backdate, or “clean up” records.

07

Produce records carefully and responsively

Provide only records that are requested and legally required or authorized. Keep complete copies of every item produced, identify the source of each record, and use a production log for electronic and hard-copy materials.

08

Ensure staff understand their roles

Instruct employees to be courteous and truthful, but not to speculate, guess, or volunteer information outside the question asked. Employees should promptly refer substantive legal, compliance, or operational questions to the designated representative and counsel.

09

Monitor physical inventory activity

If DEA conducts an inventory or reviews controlled-substance stock, have an appropriate staff member observe the process. Reconcile the DEA’s count against the practice’s records and document any discrepancies or methodology concerns immediately.

10

Conduct a post-inspection assessment and respond promptly

Debrief with counsel and key personnel after the inspection. Review any DEA-issued forms, receipts, notices, requests for records, or alleged discrepancies; preserve deadlines; and prepare a timely, accurate response or corrective-action plan where appropriate.

MOST IMPORTANT: Do Not Surrender Your DEA Registration Without Speaking with an Experienced DEA Defense Attorney

Do NOT sign a Form 104 voluntary surrender at DEA’s request during an inspection or follow-up visit. Once surrendered, the registration is terminated and the decision is nearly impossible to undo.

Do Not Let DEA Define the Narrative

Before you make statements, sign an agreement, or take corrective action, speak with experienced counsel. HLA will assess the inspection, scrutinize the evidence, and direct a coordinated response to the DEA and any related regulatory, civil, or criminal proceeding.

What DEA Investigators May Examine and Scrutinize

A DEA inspection can reach far beyond a physical count of controlled substances. Depending on the registrant, the activities at issue, and the authority DEA is relying upon, investigators may examine virtually every aspect of the practice’s controlled-substance operations, including but not limited to:

Exposure

Potential Consequences of a DEA Matter

DEA Inspection Context

Six Circumstances That Can Bring DEA Scrutiny

These circumstances help explain how an inquiry may arise. They do not establish a violation or predict its outcome.

01
Prescribing or dispensing data
Unusual patterns in controlled substance volume, patient travel or prescribing relationships can prompt questions about the underlying activity.
02
Reports from suppliers
A distributor’s suspicious-order report or due-diligence inquiry may identify activity for further examination.
03
Complaints or diversion concerns
Patient, employee or other reports can raise questions about prescribing, dispensing, security or access.
04
Unexplained inventory differences
A shortage, theft report or conflict between purchase and dispensing records may lead investigators to examine the transactions and controls.
05
A related investigation or referral
An inquiry involving another registrant, a payor or a state agency can lead to requests for your records.
06
Prior findings or registration review
Earlier deficiencies, corrective commitments or an application can lead DEA to review the registrant’s current practices.
Additional DEA Defense Questions

Frequently Asked Questions

Seven questions that come up on almost every first call. The answers below are general; specific situations require privileged consultation.

Yes. Adderall and most other ADHD stimulants are Schedule II controlled substances, and federal enforcement has focused on stimulant prescribing, including prescriptions issued through telehealth platforms. DEA investigators look at prescribing and dispensing volume, early refills, cash payments and patients traveling long distances, and at whether the pharmacy documented how it resolved those red flags before filling.
Anabolic steroids, including testosterone, are Schedule III controlled substances, so DEA investigates how they are prescribed, compounded and dispensed. Human growth hormone is not a controlled substance, but knowingly distributing it other than for an FDA-approved use on a physician’s order is a federal crime under the Food, Drug, and Cosmetic Act, so wellness and anti-aging programs can face FDA and Justice Department scrutiny alongside DEA.
You can decline to consent, but DEA can then seek an administrative inspection warrant from a federal or state judge, and once DEA has that warrant, refusing entry or inspection is itself a violation of the Controlled Substances Act. Ask for the investigators’ credentials and the basis for the inspection, and call counsel before you sign a consent form or answer substantive questions.
No, not before speaking with counsel. Signing DEA Form 104 surrenders the registration, which then terminates without a hearing, and the decision is nearly impossible to undo. The surrender can also follow you onto state board, hospital credentialing and future registration applications, so counsel should first assess whether DEA actually has grounds to suspend or revoke, and whether the matter should be contested through an Order to Show Cause hearing instead.
Provide counsel with the signed document, any accompanying agreement and the communications surrounding it. Counsel needs to assess its terms, the circumstances and any remaining proceedings before advising on possible relief or a new application. Withdrawal, reinstatement and approval of a new application should not be assumed.
Yes. Review the prescriptions associated with that prescriber, the concerns raised and your documentation of the dispensing decisions. An investigation of the prescriber does not establish that every prescription was improper, but it can create questions for the pharmacy. Counsel can examine the relevant records and advise on additional due diligence and communications with the prescriber’s counsel.
An active registration and a supplier’s decision to ship are separate matters. A wholesaler may raise its own due-diligence or suspicious-order concerns. We review the supplier’s stated reasons, the relevant purchasing and dispensing records and any related DEA contact to determine which issues need a regulatory response and which concern the commercial relationship.
