A DOJ target letter tells a physician that a federal prosecutor already has substantial evidence linking them to a crime and, in the prosecutor's own judgment, considers them a putative defendant. That classification, defined under Justice Manual Section 9-11.151, differs from being a subject, someone whose conduct falls within an investigation's scope with no such finding yet, or a witness. The letter signals real stakes without functioning as a charging document: an indictment can follow within weeks or take far longer, and how a physician responds in the interim often shapes whether it follows at all.

Target, Subject, or Witness: What the Letter Signals

The three-tier framework comes directly from Justice Manual Section 9-11.151. A witness is someone believed to have information relevant to an investigation, with no suggestion of wrongdoing. A subject is someone whose conduct falls within the scope of the investigation, though the prosecutor has yet to reach a finding on that person. A target is someone the prosecutor already has substantial evidence against and, in the prosecutor's own judgment, considers a putative defendant. Status shifts as an investigation develops: a subject who testifies inconsistently, or whose own records undercut an earlier account, can become a target within weeks, and a target letter is often the first outside signal that the shift already happened.

The Window a Target Letter Opens

No federal statute sets a deadline for prosecutors to indict after sending a target letter. What does have a clock is the underlying offense: a violation of the federal healthcare fraud statute, 18 U.S.C. Section 1347, carries no limitations period of its own, so the default five-year period under 18 U.S.C. Section 3282 controls. As that deadline approaches, prosecutors often ask the target to sign a tolling agreement, extending the period in exchange for holding the charging decision open. Justice Manual Section 9-11.153 separately encourages prosecutors to notify a target a reasonable time before seeking an indictment so the target has an opportunity to respond, except in routine or sensitive matters. That policy, combined with the grand jury subpoena that often accompanies or follows the letter, is the practical window: a stretch of time, not fixed by law, during which counsel can present evidence, negotiate a declination, or prepare for indictment.

Reading the Letter's Language Accurately

The statutes named in the letter define the exposure. A letter citing the federal healthcare fraud statute alongside the Anti-Kickback Statute or Stark Law signals a criminal kickback or self-referral theory, not a routine coding dispute. A civil investigative demand, by contrast, signals a parallel or separate civil False Claims Act inquiry, a different track with different consequences even when it grows out of the same referral pattern. Stark Law vs the Anti-Kickback Statute: The Differences That Matter explains why the two statutes carry different exposure even when the underlying conduct looks similar, and that distinction shapes which defense actually answers the letter.

The Response Decision

Once the classification and the statute are clear, the decision is narrow: respond through counsel, or say nothing and wait. Physicians who speak informally with agents, even to explain what they believe is an honest scheduling or coding mistake, hand the government a recorded statement it did not have before. Counsel's response usually takes one of three forms: a request for a pre-indictment meeting to present exculpatory facts, a negotiated tolling agreement that buys time to investigate the underlying claims, or a direct written answer built on the record itself. Billing Error or Fraud: Where Enforcement Draws the Line sets out how prosecutors separate a documentation lapse from intentional misconduct, the same line a target letter response has to draw. Where the letter's theory rests on remuneration or referral patterns, The Anti-Kickback Statute: Remuneration, Intent, and Safe Harbors covers the safe harbors that can narrow or eliminate the exposure the letter describes.

A target letter is an invitation to change the prosecutor's mind before the charging decision is final, not a verdict already reached.

Why Early Legal Counsel Is Critical

It is critical that physicians promptly retain experienced healthcare defense counsel upon receiving a target letter, a grand jury subpoena, or any other government inquiry. Early legal intervention can protect the physician's rights, shape whether prosecutors ever reach a charging decision, avoid inadvertent admissions during informal contact with agents, and allow counsel to communicate with investigators on the physician's behalf. Delaying representation narrows the window the letter opens and can affect the outcome of the matter.
