Federal agents can arrive at a physician's practice with a signed search warrant and begin removing patient files, billing records, and computers within minutes. A search warrant carries the authority of Federal Rule of Criminal Procedure 41 and the Fourth Amendment: agents may search the areas and seize the items described in the warrant's attachment, without advance notice and without the practice's consent. What happens in the first hour, before the last box leaves the building, often shapes how the next eighteen months of the investigation unfold.
Confirm the Warrant Is Valid and Review Its Scope
Ask the lead agent for a copy of the warrant and its attachment before the search proceeds. The attachment lists the specific locations and items agents are authorized to search and seize; conduct that exceeds that description falls outside the warrant's scope. Confirm the warrant is signed by a federal magistrate judge and that execution falls within the daytime hours Rule 41 requires, generally 6:00 a.m. to 10:00 p.m., unless the warrant specifically authorizes otherwise. Search warrants at medical practices frequently rest on allegations tied to the anti-kickback statute or Stark Law. Note any apparent scope problems in writing rather than raising them physically with agents on scene.
Instruct Staff Without Obstructing the Search
Gather staff calmly and give clear instructions before agents begin individual conversations. No one should touch, move, or destroy any document, file, or device once the warrant is presented; destroying or altering records during an active federal search can itself become a separate criminal exposure, apart from whatever the warrant is investigating. Staff are not required to answer questions about billing practices, referral arrangements, or clinical decisions. The Fifth Amendment protects each person's right to decline to answer without counsel present, and declining to answer is not obstruction. Direct every substantive question, from agents or from colleagues, to the practice's attorney.
Assert Attorney-Client Privilege Over Protected Files
Identify any files, emails, or physical correspondence involving the practice's attorneys before agents reach them, and tell the case agent on scene that those materials are privileged and should be set aside rather than reviewed. The Department of Justice typically assigns a separate filter team, walled off from the prosecution team, to screen contested material for privilege, but that screening is not automatic protection. Follow the verbal notice with a written letter the same day naming the privileged categories; objections raised only in conversation are hard to reconstruct once the search is over.
Preserve a Record of the Search and the Seizure
Rule 41(f) requires the executing officer to leave a copy of the warrant and either a receipt for the property taken or an inventory of seized items at the premises, and to return that inventory to the magistrate judge. Request a copy of both before agents leave. Separately, have someone on staff, not the physician under investigation, keep a written log: each agent's name and badge number, the time agents arrived and departed, which rooms and files were searched, and any statements staff made or were asked to make. That contemporaneous record becomes the factual baseline for everything that follows, including any challenge to the warrant's scope.
Search warrants of this kind rarely arrive as an isolated event. Physicians building context on the underlying theories these investigations pursue can review our comparison of Stark Law vs the Anti-Kickback Statute, our overview of the Anti-Kickback Statute for providers, and our discussion of where a billing error becomes fraud.
The first hour of a federal search warrant produces the only contemporaneous record of what agents did and what staff said, and a practice with no record of its own is left arguing from memory months later.
Why Early Legal Counsel Is Critical
It is critical that physicians promptly retain experienced healthcare defense counsel the moment federal agents arrive with a search warrant. Early legal intervention can protect the practice's rights during execution, ensure staff understand they are not required to answer questions without counsel present, preserve privilege claims over protected files, and position the practice to respond to any grand jury subpoena or civil investigative demand that follows. Delaying legal representation can significantly affect the outcome of the investigation and expose the practice to unnecessary risk.
