What Should I Do if the DEA is Investigating My Ketamine Prescription Practices

The response to a DEA investigation of ketamine prescribing practices is structured around the same principles as the response to a DEA investigation of opioid prescribing practices: retain experienced counsel immediately, preserve all relevant records, do not speak with investigators without counsel present, and develop a defense strategy before making any decision about how to engage the investigation.

The specific features of a ketamine investigation that differ from an opioid investigation, described throughout this section, affect the content of the defense strategy but not the basic framework for responding to the investigation. The practitioner who has been contacted by DEA agents about their ketamine prescribing, who has received a DEA subpoena for ketamine-related records, or who has had their controlled substance inventory audited in connection with ketamine administration needs experienced counsel as urgently as the practitioner whose opioid prescribing has attracted DEA attention.

Immediate Steps

The immediate steps following any indication of DEA interest in a practitioner’s ketamine practice are the same as for any DEA investigation. Do not speak with DEA agents without counsel present. Do not produce any records in response to an informal request before counsel has reviewed the request and the applicable legal obligations. Preserve all records that may be relevant to the investigation, including ketamine administration records, patient medical records, billing records, and controlled substance inventory records. Contact experienced federal healthcare fraud defense counsel and describe the specific nature of the DEA’s interest.

The preservation of ketamine administration records is particularly important because those records are both the primary evidence the government will rely on to establish that the administrations were clinically appropriate and the primary evidence the defense will use to demonstrate the same thing. A practitioner who discovers that their ketamine administration records are incomplete or that the controlled substance inventory records do not match the documented administrations has identified a compliance problem that must be assessed by counsel before any engagement with the DEA occurs.

The Clinical Record Review

The internal review of the ketamine clinical record, conducted under counsel’s direction and protected by the attorney-client privilege, is the first substantive task in the defense of a ketamine investigation. The review should assess whether the records adequately document the clinical basis for each ketamine administration, whether the dosing and monitoring protocols reflected in the records are consistent with applicable clinical guidelines, whether the patient population treated is consistent with the clinical indications for which ketamine was administered, and whether the controlled substance inventory records reconcile with the documented administrations.

The ketamine-specific clinical standards, including the professional society guidelines for ketamine infusion therapy, the FDA-approved esketamine protocols, and the published clinical evidence for off-label applications, are the standards against which the defense medical expert will assess the records. Counsel should identify and retain a medical expert with specific experience in ketamine clinical practice who can review the records against those standards and provide an opinion about the clinical appropriateness of the administrations.

The Corporate Structure Review

If the ketamine practice is organized through a corporate structure involving management services organizations, professional medical corporations, or other entities, the investigation may extend to the corporate structure and the financial relationships among the entities. The review should assess whether the corporate structure complies with the applicable state CPOM doctrine, whether any financial relationships among the entities create anti-kickback exposure, and whether the entity’s compliance with DEA registration requirements at each operating location is complete.

Structural compliance failures discovered through the internal review should be assessed by counsel for their legal significance and for whether voluntary correction or disclosure is appropriate. A structural compliance failure that is identified and corrected before the government identifies it is a compliance failure whose remediation reflects good faith. The same failure identified by the government after the practitioner was aware of it but took no action is evidence of indifference that the government will characterize unfavorably.

Engaging the Investigation

After the internal review has provided a complete picture of the practice’s clinical and compliance record, counsel can assess the strategic options for engaging the DEA investigation. Pre-investigation engagement through a presentation to the prosecuting office, if the clinical record supports it, is available in ketamine cases on the same basis as in opioid cases. The clinical expert opinion that the administrations were within the usual course of professional practice, presented in a proffer session or written submission before any charge is filed, is the same tool available in both contexts.

The ketamine investigation that arrives at a practitioner whose clinical records are thorough, whose controlled substance inventory is accurately maintained, whose corporate structure is legally compliant, and who retained experienced counsel before making any statements to investigators is an investigation that begins from the most defensible starting point available. The investigation that arrives at a practitioner whose records are sparse, whose inventory is unreconciled, and who has already spoken with DEA agents begins from a position that requires reconstruction rather than defense. The starting point is not fixed. It is determined by what was done before the investigation arrived and in the first days after it did.

The Consultation Is Available Now

The practitioner whose ketamine prescribing has attracted DEA attention, who has received a subpoena or an inspection notice, or who has any reason to believe that their ketamine practice is under regulatory scrutiny has a situation that warrants consultation with experienced federal healthcare fraud defense counsel. That consultation is available now, is protected by the attorney-client privilege, and will provide the practitioner with the information necessary to understand their exposure and the options available for addressing it. The first call is where the response begins.

Former investigator perspective on this topic

Retired FBI healthcare fraud agent here. Spent 15 years on the enforcement side. Reading this article and the comments — I want to offer some perspective from the other side of the table.

Most investigations start with data, not complaints. PDMP data, Medicare billing data, pharmacy purchasing records. By the time an agent contacts you, they've usually been looking at your numbers for months. That's why having good documentation matters — the data will flag you, but the documentation either explains the data or doesn't.

63
FF former_fed_investigator Former Federal Agent 2w ago

Talking. Hands down. Doctors who talked to agents without a lawyer — trying to explain their way out of it — gave us 80% of the evidence we needed. Every single time. Get a lawyer first. Always.

44
HD healthcare_defense_atty Attorney 2w ago

Seconding this emphatically. I've represented dozens of healthcare providers. The ones who called me BEFORE talking to agents had dramatically better outcomes than the ones who called AFTER. It's not about having something to hide — it's about having your rights protected from the start.

AD anxious_doc_2025 Physician 2w ago

This is incredibly valuable perspective. Can you share — what's the single biggest mistake you saw doctors make when they first learned they were being investigated?

49
WP worried_physician DO 2w ago

Going through exactly what this article describes — anyone else?

Just read this article about "What Should I Do if the DEA is Investigating My Ketamine Prescription Practices" and it hit close to home. I'm a pain management physician and I've been losing sleep over this. I got a letter from the DEA requesting records. I haven't been contacted directly by any agency yet but the anxiety is crushing. Anyone been through something similar?

50
HD healthcare_defense_atty Attorney 2w ago

First: do NOT speak to any federal agent without counsel. Period. Not the DEA, not the OIG, not the FBI. You have the right to counsel and exercising that right cannot be held against you.

Second: get a consultation NOW, before anything formal happens. Pre-investigation counsel is dramatically more effective (and less expensive) than post-indictment defense. Many healthcare fraud defense attorneys offer free initial consultations.

Third: do NOT alter any records. Do NOT destroy any documents. Do NOT discuss this with staff beyond what's necessary for patient care. Any of those actions can become separate criminal charges (obstruction, evidence tampering) even if the underlying prescribing was entirely legitimate.

SI survived_investigation Physician — Investigated & Cleared 2w ago

Went through a DEA investigation 3 years ago. It was the worst 18 months of my life but I came out clean. Best advice: get a lawyer who specifically handles federal healthcare cases (not a general criminal attorney), follow their instructions to the letter, and keep practicing medicine. The investigation itself is not a conviction and most of your patients still need you.

If you haven't already, start documenting everything meticulously going forward. Every prescribing decision should have clear clinical justification in the chart. This protects you regardless of whether an investigation materializes.

My wife is a doctor and I’m terrified after reading this

My husband is a psychiatrist and we just learned the practice is being looked at by the DEA. We have everything tied up in the practice. I don't know anything about criminal defense. How do we even start? How much does this cost? Can they take our house?

39
FM fed_med_lawyer Attorney 1w ago

I understand the fear. Here's what you need to know:

1. Attorney fees: Federal healthcare fraud defense typically costs $15,000-50,000 depending on the stage and complexity. Pre-investigation work is on the lower end.

2. Your home: In most states, homestead exemptions protect your primary residence. Federal forfeiture requires a direct connection between the property and the alleged criminal activity — simply being a doctor who's investigated doesn't put your house at risk.

3. First step: Call a federal healthcare fraud defense attorney this week. Not a general lawyer. Someone who has handled DEA/OIG cases before. Most will do a free phone consultation to assess the situation.

4. Don't panic: Investigation ≠ charges. Charges ≠ conviction. Many investigations are closed without action.

23
BT been_there_doc 1w ago

I'm the spouse of a physician who went through a 2-year DEA investigation. It was resolved favorably. The emotional toll is real — please consider therapy for both of you. We found a support group for medical professionals under investigation that helped enormously. You're not alone in this.

How much does a federal healthcare fraud attorney actually cost?

I need to talk to someone but I'm a solo practitioner. I don't have a hospital legal department behind me. What does it actually cost to retain a federal healthcare defense attorney? Just a consultation vs. ongoing representation? Can I even afford this?

41
HD healthcare_defense_atty Attorney 1w ago

Typical ranges:

- Initial consultation: Free to $500. Many firms offer free phone consultations.
- Pre-investigation advisory/compliance review: $3,000–$10,000
- Responding to a subpoena: $5,000–$15,000
- Full investigation representation: $25,000–$75,000+
- Trial defense: $100,000–$500,000+

The earlier you engage, the less it costs. A $5,000 consultation that prevents a $50,000 investigation is the best money you'll ever spend. Most attorneys will work out payment plans for solo practitioners.

29
SI survived_investigation Physician — Investigated & Cleared 1w ago

I paid about $35k total for my defense over 18 months. Was it painful? Yes. Would I do it again? In a heartbeat. The alternative — trying to handle it myself or hiring a cheap general attorney — would have cost me my license and my freedom.

30
NI NP_in_pain_mgmt PA-C 2w ago

Does this apply to NPs and PAs too, or just physicians?

I'm a physician assistant with prescriptive authority. Does what this article discusses about "What Should I Do if the DEA is Investiga" apply equally to mid-level providers? I prescribe controlled substances for chronic pain under my collaborating physician's DEA number. If something goes wrong, who is at risk — me, the supervising physician, or both?

27
FM fed_med_lawyer Attorney 1w ago

Both. If you have your own DEA registration, you bear independent responsibility for your prescribing. If you're prescribing under a collaborating physician's DEA number, the supervising physician also has exposure. The DEA does not limit investigations to physicians — NPs, PAs, dentists, podiatrists, and veterinarians have all been targets of federal prescribing investigations.

The same standard applies: prescriptions must be issued for a legitimate medical purpose in the usual course of professional practice. Document your clinical reasoning for every controlled substance prescription.

19
NC NP_colleague PA-C 1w ago

I got my own DEA number specifically so I wouldn't be dragged into my collaborating physician's issues. Worth considering if you haven't already. It also makes your prescribing cleaner from a documentation standpoint.

Pharmacist perspective on “What Should I Do if the DEA is Investigating My Ke”

Running an independent pharmacy and this topic affects us directly. I've had to make some difficult decisions about which prescriptions to fill recently. It feels like there's no right answer sometimes. Any other pharmacists dealing with this?

34
HD healthcare_defense_atty Attorney 2w ago

Pharmacists are increasingly being named in federal healthcare fraud cases. Your documentation is your shield. Invest in a compliance program if you don't have one — it's far cheaper than a defense. And know that you DO have the right to refuse to fill prescriptions you believe are not for a legitimate medical purpose. That right is explicitly recognized in federal regulation.

23
FP fellow_pharmacist PharmD 2w ago

You're not alone. The "corresponding responsibility" doctrine puts us in an impossible position. Document EVERYTHING — every conversation with a prescriber about a questionable script, every refusal, every verification call. If you have a compliance program, follow it religiously. If you don't have one, get one yesterday.

26
CM clinic_manager_anon Office Manager 3w ago

What should clinic staff know about this topic?

I'm a practice manager at a urgent care. After reading about "What Should I Do if the DEA is Investiga" — what should front-line staff (receptionists, medical assistants, billing staff) know? We want to make sure we're not inadvertently creating problems. Should we be training staff differently?

20
CO compliance_officer_RN Compliance 3w ago

Key things for staff:

1. Never alter medical records after the fact for any reason
2. If a federal agent shows up, be polite but say "I need to contact our attorney before providing any information"
3. Don't discuss patient cases with anyone outside the practice
4. Follow your office's prescription verification protocol exactly — no shortcuts
5. Document any patient behavior that seems concerning (doctor shopping, lost prescriptions, etc.)

Annual compliance training for all staff is worth every penny.

24
PA podiatrist_anon DVM 1mo ago

Does this apply to podiatrists too?

I'm a dentist who prescribes post-surgical opioids. Most of the articles I see focus on physicians and pain management. Are veterinarians really at risk for DEA scrutiny?

30
HD healthcare_defense_atty Attorney 4w ago

Yes. Any DEA registrant who prescribes controlled substances is subject to the same federal standards. Dentists are increasingly scrutinized for opioid prescribing — the CDC's prescribing guidelines have been applied to dental practice. Veterinarians have seen a rise in diversion cases (drugs prescribed for animals being diverted to human use). The DEA does not distinguish by specialty — they look at prescribing patterns and whether they're consistent with legitimate medical practice.
