An FBI agent's letter, or an HHS-OIG investigator's visit, asking a physician practice to turn over records is not a subpoena. No federal statute requires the practice to comply with it, and a court is not standing behind the request if the practice declines. That gap between what a voluntary request asks for and what it can actually compel is where a practice can get the response wrong, either handing over files on the spot or ignoring the letter and hoping it goes away. Both choices skip past the real question, what happens to the records once the agent leaves without them.
A Request Is Not a Subpoena
Absent a grand jury subpoena, an administrative subpoena, a civil investigative demand, a search warrant, or a court order, a document request or interview request from FBI or HHS-OIG agents is voluntary. A practice can decline it, narrow it, or ask that it come in writing before responding, and none of those choices violates any statute. The agency's recourse if the practice declines is to seek compulsory process instead. A subpoena can be challenged in court and quashed or modified if compliance would be unreasonable or oppressive, and a voluntary request has no equivalent check, which is also why it can end up asking for more than a subpoena covering the same matter would. The request's boundaries are whatever the agent wrote or said.
HIPAA's Limit on a Voluntary Request
A letter or visit, by itself, does not give a physician practice a basis under the HIPAA Privacy Rule to hand over patient records. Under 45 C.F.R. § 164.512(f), a covered entity may disclose protected health information in response to an administrative request, such as an administrative subpoena or civil investigative demand, only when the response is required by law, the information sought is relevant and specific in scope, and de-identified information could not reasonably serve the same purpose. A voluntary letter asking a practice to produce files does not meet that threshold on its own. Producing the records anyway requires either the patient's authorization or another basis under the Privacy Rule, a determination the practice should make before deciding what, if anything, to send.
Preservation Duties Start Before Any Subpoena Does
Declining or narrowing a voluntary request does not relax what a practice has to keep. 18 U.S.C. § 1519 makes it a federal crime, punishable by up to 20 years, to knowingly alter, destroy, conceal, or falsify a record with intent to impede a federal investigation, and the statute reaches conduct taken in contemplation of a matter, not only after an investigation is already open. 18 U.S.C. § 1512(c) carries the same 20-year exposure for destroying or concealing a record to impair its availability for an official proceeding, and under 1512(f)(1) that proceeding does not have to be pending yet. An agent's visit, even one the practice is free to turn away, is the kind of notice that can start this clock. Once it has, the practice's usual document retention schedule stops being the only consideration.
A federal agent does not need a subpoena to start the preservation clock. The agent only needs to show up.
Why Early Legal Counsel Is Critical
It is critical that a physician practice promptly retain experienced healthcare defense counsel upon receiving a voluntary document request, an investigative visit, or any other government inquiry. Early legal intervention can protect the practice's rights, ensure the response is properly scoped, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the practice's behalf. Delaying legal representation can affect the outcome of a matter and expose the practice to risk that a properly scoped response would have avoided.
