Filing Deadlines

    Texas Medical Malpractice Statute of Limitations

    The 2-Year Rule — and Why You Should Act Sooner

    Texas Civil Practice & Remedies Code § 74.251 — part of the Texas Medical Liability Act — gives most medical-malpractice plaintiffs two years to file a lawsuit. The clock starts on the date of the negligent act or omission, the date the medical or dental treatment that gave rise to the claim was completed, or the date the hospitalization that gave rise to the claim was completed — whichever is latest.

    Two years sounds like a long time. In practice, it is short. A Texas malpractice case requires obtaining and reviewing complete medical records, identifying the right defendants, preparing a 60-day pre-suit notice, and lining up a qualified medical expert who can author a Chapter 74 expert report within 120 days of filing. Lawyers routinely turn away cases brought to them with only a few months left on the clock — not because the case lacks merit, but because there is no longer enough time to develop the evidence Texas law requires.

    The page below walks through the rule, the major exceptions, and the procedural deadlines that follow once you do file. None of it is a substitute for advice from an attorney about your specific facts.

    Section 1

    When Does the Clock Start?

    Section 74.251(a) gives three possible start dates and tells the court to use whichever is latest:

    1
    The Negligent Act

    The date the doctor, nurse, or hospital did (or failed to do) the thing that caused the harm — for example, the date of a missed diagnosis or a surgical error.

    2
    Last Day of Treatment

    The last day the provider treated the specific condition at issue. This matters most for ongoing courses of treatment, like chemotherapy or prenatal care.

    3
    End of Hospitalization

    The date the patient was discharged from the hospitalization that gave rise to the claim. Useful when the negligence spanned multiple days inpatient.

    Important: Texas does not generally apply a discovery rule under Chapter 74. The clock typically runs from the negligent act, not from when you discovered the harm. The exceptions below are narrow.

    Section 2

    Exceptions That Can Extend the Deadline

    Tolling
    Minors

    Children Under 12

    Section 74.251(a) provides that for children under the age of 12 at the time of the negligence, the lawsuit must be filed before the child's 14th birthday. Texas appellate courts have used the constitutional open-courts doctrine in some cases to extend that deadline where applying it strictly would unconstitutionally cut off a minor's claim. Because the rule is unsettled at the margins, do not assume your family has additional time — talk to a lawyer immediately.

    Statutory
    Foreign Object

    Retained Sponges and Instruments

    When a surgical sponge, needle, clamp, or other foreign object is unintentionally left inside a patient's body, the two-year clock runs from the date the object was discovered (or reasonably should have been discovered) — not from the date of the original procedure. This is the most common exception that lengthens the filing window in practice. See our surgical-error practice page for more.

    Equitable
    Concealment

    Fraudulent Concealment

    When a healthcare provider actively conceals their own negligence — for example, by altering records or hiding a known intra-operative complication — the statute of limitations may be tolled until the patient discovers, or reasonably could have discovered, the underlying malpractice. Concealment is fact-intensive and requires evidence; it does not apply to ordinary failures to disclose.

    Constitutional
    Open Courts

    The Open-Courts Doctrine

    Article I, § 13 of the Texas Constitution prohibits the legislature from cutting off a well-established cause of action through an unreasonable filing deadline. When applying the strict 2-year rule would deny a plaintiff any meaningful chance to discover the injury and file in time, the Texas Supreme Court has held the limitations period unconstitutional as applied. This doctrine is narrow and case-specific — but it can be the difference between a claim and no claim.

    Section 3

    The 10-Year Statute of Repose

    Section 74.251(b) creates a separate, absolute outer limit: no medical-malpractice claim may be filed more than 10 years after the date of the negligent act or omission. This 10-year statute of repose generally cannot be tolled, extended by the discovery rule, or waived by ordinary application of the open-courts doctrine.

    In practice, the repose statute is most likely to come up in long-latency cases — such as cancers traceable to old missed diagnoses, or birth injuries first connected to a prenatal error many years later. If your potential claim is approaching the 10-year mark, treat it as urgent.

    Section 4

    What "Filing" Actually Looks Like

    Once you decide to pursue a claim, Texas law layers two more procedural deadlines on top of the 2-year filing requirement. Both are easy to miss without an experienced lawyer.

    1
    Day -60

    60-Day Pre-Suit Notice

    Section 74.051 requires written notice of the claim, with a medical-records authorization, served on each potential defendant at least 60 days before filing. Failure to give proper notice can extend the limitations period — but it can also create grounds to dismiss certain claims.

    2
    Day 0

    File the Lawsuit

    "Filing" means the lawsuit is on file with the court, the defendants are named, and (in most counties) service has issued. Filing must occur on or before the 2-year deadline.

    3
    Day +120

    Serve a Chapter 74 Expert Report

    Within 120 days of filing, plaintiffs must serve a qualified medical expert report under § 74.351. The report must identify the standard of care, how it was breached, and how the breach caused the harm. Failure to serve a timely, adequate report results in dismissal — with attorney's fees awarded against the plaintiff.

    Year 10

    The Repose Wall

    Regardless of any tolling or discovery argument, no claim can be filed more than 10 years after the negligent act. Past this date, the statute of repose generally bars the case forever.

    FAQ

    Frequently Asked Questions

    Texas Civil Practice & Remedies Code § 74.251 sets a two-year deadline for medical and dental liability claims. The clock generally begins on the date of the negligent act or omission, the date the medical or dental treatment that gave rise to the claim was completed, or the date the hospitalization for which the claim is made was completed — whichever is latest. Missing this deadline almost always means losing the right to sue forever, so the safest course is to consult a qualified attorney as soon as you suspect a problem.

    Texas does not generally apply a discovery rule to medical-malpractice claims under Chapter 74 — the clock typically runs from the act of negligence, not from the date you discovered it. There are two important exceptions: (1) the foreign-object rule, which resets the clock to discovery when a sponge, instrument, or similar object is unintentionally left inside the body, and (2) the Texas Constitution's open-courts doctrine, which can extend the deadline when applying a strict cutoff would unconstitutionally cut off your right to sue before you reasonably could have known of the injury.

    Texas § 74.251(a) provides that for children under the age of 12 at the time of the negligent act, the action must be filed before the child's 14th birthday. However, Texas appellate courts have applied the open-courts doctrine in some situations to extend that deadline when applying it strictly would deprive a minor of a meaningful chance to bring a constitutionally protected claim. Because the rule is unsettled at the edges, parents should never assume they have unlimited time — speak with a Texas medical-malpractice attorney as soon as possible.

    Section 74.251(b) imposes an absolute 10-year outer limit on medical-malpractice claims, measured from the date of the negligent act or omission. The repose statute is a hard ceiling — even valid tolling, the discovery rule, or open-courts arguments cannot generally push a claim past 10 years. Narrow constitutional exceptions exist but are difficult to invoke. If your potential claim is approaching the 10-year mark, you should treat the matter as urgent.

    This page is general legal information, not legal advice. The application of Texas medical-malpractice deadlines depends on the specific facts of each case. If you suspect malpractice, contact a qualified Texas medical-malpractice attorney without delay.
