There is no fixed number of years that answers how far back medical records can be subpoenaed. The reach depends on what the lawsuit is about, whether the records are relevant to the specific claims, what special protections apply to the type of record, and whether the provider still has them. Records from five, ten, or twenty years ago can all be within reach if the requesting party can tie them to an issue in the case.
Relevance Is What Controls the Reach
The scope of a medical records subpoena is governed by relevance and proportionality, not by a calendar cutoff. Under the federal discovery rules, a party can obtain non-privileged information that is relevant to a claim or defense and proportional to the needs of the case.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Most state courts follow a similar framework.
Proportionality is the practical guardrail. A court weighs the importance of the issues, the amount at stake, each side’s access to the information, and whether the burden of producing the records outweighs the likely benefit.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery A subpoena demanding every record generated since birth will almost never survive that test. A targeted request for a decade of orthopedic records from someone claiming a back injury usually will.
That case-by-case analysis is what stops fishing expeditions through a person’s full medical history. In a lawsuit over a broken arm, fifteen years of orthopedic records for that arm could easily qualify as relevant because they might reveal earlier injuries or pre-existing conditions that affect damages. A demand for unrelated gynecological records from the same period would not survive a relevance challenge. When the parties disagree, a judge can narrow the subpoena by restricting the time period, limiting it to specific conditions, or both.2Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
How the Type of Case Changes the Window
Because the reach turns on relevance, the type of lawsuit is what gives that standard its real-world meaning. A ten-year look-back can be reasonable in one case and excessive in another.
Personal Injury
Personal injury cases tend to produce the widest look-back periods for the specific body part or condition in dispute. Claim that a car accident caused a back injury and the defense will subpoena years of records from orthopedic doctors, chiropractors, and physical therapists to test whether the problem pre-existed the crash. Requests spanning ten to fifteen years are common, and courts regularly allow them when they focus on the relevant diagnosis.
Social Security Disability
Social Security disability follows a different logic. The SSA must develop a claimant’s complete medical history for at least the twelve months before the application filing date.3Social Security Administration. 20 CFR 404.1512 – Responsibility for Evidence That twelve months is a floor, not a ceiling. The agency looks further back when it needs to understand how a condition developed over time, particularly for progressive conditions like degenerative disc disease or multiple sclerosis. If there is reason to believe the disability began earlier, the SSA will develop the medical history from that earlier period as well.4Social Security Administration. POMS DI 22505.001 – Medical and Nonmedical Evidence
Workers’ Compensation
Workers’ compensation focuses on the specific workplace injury, so the relevant window is generally narrower. The records at issue are those documenting the injury and the treatment that followed. An employer or insurer may still seek older records if they suspect the condition predated the workplace incident.
Employment and ADA Cases
Employment cases under the Americans with Disabilities Act add another layer. The ADA requires employers to keep employee medical information in separate confidential files, and that duty continues after the employment relationship ends. A subpoena signed by a court clerk may not qualify as the kind of court order needed to compel disclosure of those files. The look-back typically tracks the time frame relevant to the alleged discrimination rather than the employee’s full medical history.
Divorce and Custody
Medical records in family law cases are generally off-limits unless a party’s physical or mental health has been explicitly put at issue. If one parent raises concerns about the other’s mental fitness for custody, a court may allow a narrowly tailored subpoena for mental health treatment records. A blanket request for a spouse’s full medical history will not survive a relevance objection in most courts.
Records That Get Extra Protection, Regardless of Age
Some categories of health information receive heightened legal protection that can block disclosure entirely, no matter how old the records are or how relevant the requesting party claims they would be.
Psychotherapy Notes
HIPAA draws a sharp line between ordinary mental health treatment records and psychotherapy notes. Psychotherapy notes are a therapist’s private notes analyzing counseling conversations, kept separate from the rest of the chart. They do not include session start and stop times, medication records, diagnosis, treatment plans, or progress summaries. A covered entity generally cannot release psychotherapy notes without the patient’s specific written authorization, even in response to a subpoena.5eCFR. 45 CFR 164.508 – Uses and Disclosures for Which an Authorization Is Required Narrow exceptions include the therapist using the notes for treatment and a provider defending itself in a lawsuit brought by the patient.
Psychotherapist-Patient Privilege in Federal Court
In federal court, confidential communications with a licensed psychotherapist are shielded from compelled disclosure. The Supreme Court recognized this privilege in 1996 and extended it to psychiatrists, psychologists, and licensed social workers providing psychotherapy. The Court rejected a balancing test that would have let judges override the privilege by weighing the need for disclosure against the patient’s privacy.6Justia U.S. Supreme Court Center. Jaffee v. Redmond, 518 U.S. 1 Most states recognize some version of this privilege, though the scope varies.
Substance Use Disorder Records
Records from federally assisted substance use disorder treatment programs carry some of the strongest confidentiality protections in American law under 42 CFR Part 2.7eCFR. 42 CFR Part 2 – Confidentiality of Substance Use Disorder Patient Records These records cannot be used against a patient in any legal proceeding without the patient’s written consent or a specific court order. A standard subpoena is not enough.8U.S. Department of Health and Human Services. Fact Sheet 42 CFR Part 2 Final Rule
To get such a court order, the requesting party must show good cause. That means proving two things: that no other way to obtain the information is available or would work, and that the public interest in disclosure outweighs the potential harm to the patient, the doctor-patient relationship, and the treatment program.9eCFR. 42 CFR 2.64 – Procedures and Criteria for Orders Authorizing Uses and Disclosures for Noncriminal Purposes That is a deliberately high bar.
The Practical Ceiling: Whether the Records Still Exist
Even a legally valid subpoena that reaches back decades can come back empty. HIPAA does not require healthcare providers to retain medical records for any specific period.10U.S. Department of Health and Human Services. Does the HIPAA Privacy Rule Require Covered Entities to Keep Medical Records for Any Period Retention periods are set by state law, and they vary significantly.
For adult patients, most states require providers to keep records for somewhere between five and eleven years after the last date of treatment. Pediatric records typically must be retained until the child reaches the age of majority plus several additional years, which can push the retention window to age 21, 25, or even 30 depending on the state. When federal program rules apply, such as Medicare requiring six years of records from the date of service, providers must follow whichever rule imposes the longest retention period.
A subpoena seeking records from fifteen years ago may return nothing simply because the provider was legally permitted to destroy them. If a lawsuit is foreseeable, keeping your own copies before records age out of the provider’s retention window is worth the effort.
What to Do If a Subpoena Reaches Too Far
If you receive a subpoena for medical records that you believe is overly broad or seeks irrelevant information, you can challenge it. The process starts with serving a written objection on the party that issued the subpoena. Under the federal rules, the objection must be served before the compliance deadline or within 14 days of receiving the subpoena, whichever comes first.2Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena A timely objection pauses the obligation to produce the records until the dispute is resolved.
If the requesting party pushes back, the next step is a formal motion. A motion to quash asks the judge to throw out the subpoena entirely. A motion for a protective order asks the judge to narrow its scope, for example by cutting the time period from twenty years to five, or by restricting production to records about a specific condition. Courts must quash a subpoena that requires disclosure of privileged or protected information when no exception applies.2Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
HIPAA also imposes procedural requirements on the requesting party before a healthcare provider can hand records over. When a court order compels disclosure, the provider may release only what the order specifically authorizes. A subpoena without a court order requires the requesting party to show either that they notified the patient about the request and gave enough time to object, or that they sought a qualified protective order limiting how the information can be used.11eCFR. 45 CFR 164.512 – Uses and Disclosures for Which an Authorization or Opportunity to Agree or Object Is Not Required If a patient objects within the allowed time, production pauses until a judge resolves the dispute.12U.S. Department of Health and Human Services. Court Orders and Subpoenas
Ignoring a valid subpoena is not a safe option. A person who fails to comply without adequate justification can be held in contempt of court, which may bring monetary sanctions and an order to pay the other side’s attorney’s fees.2Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena The right move is always to object or file a motion rather than let the deadline pass in silence.
