Texas Medical Malpractice Statute of Limitations Explained

How Long Do You Have to File a Texas Medical Malpractice Lawsuit?

Texas law gives most patients two years to file a medical malpractice lawsuit, counted from the date of the negligent act itself or, when the treatment continued past that single event, from the date that treatment ended. Section 74.251(a) of the Texas Civil Practice and Remedies Code sets this out directly. No health care liability claim may be filed unless it is brought within two years from the occurrence of the breach or tort, or from the date the treatment that is the subject of the claim was completed.

“Completion of treatment” matters because a single course of care rarely ends the moment an error happens. If a surgeon leaves an instrument behind during an operation, the surgery date is one possible start point, but if the patient continued follow-up care with that same surgeon for the same condition, the clock may instead run from the date that ongoing treatment concluded. Getting this date right often decides whether a claim is still alive.

This two-year period runs regardless of when the patient actually realized something had gone wrong. A patient who spent a year and a half recovering before connecting their complications to a medical error is still bound by the same two-year clock as anyone else, a distinction that surprises many families.

Does Texas Have a Discovery Rule for Medical Malpractice Claims?

No. Many other types of Texas lawsuits let the filing clock start when the injured person discovers the harm, but that general discovery rule does not apply to medical malpractice claims. Section 74.251 runs from the date of the negligent act or the completion of treatment, and it makes no exception for when a patient actually learned that something had gone wrong.

A narrow safety valve does exist. In rare cases where an injury genuinely could not have been discovered within the two-year period, the open courts protection in Article I, Section 13 of the Texas Constitution may allow a claim to proceed despite the missed deadline. Courts apply this exception carefully, and it can never extend a claim beyond the 10-year statute of repose described below.

In cases where a provider actively concealed facts material to the claim, Texas recognizes a form of tolling for that concealment , though this exception is narrow and fact-intensive, not a routine way around the two-year clock. For most patients, the safest assumption is that the clock is already running from the date of the negligent act, whether or not the harm has been recognized yet.

The Chapter 74 Pre-Suit Notice Letter and How It Extends Your Deadline

Before a medical malpractice lawsuit can be filed in Texas, the law requires sending each defendant a formal notice letter at least 60 days in advance, and that notice does more than warn the defendant. It automatically adds time to the filing deadline. Under Section 74.051(a), the notice must go out by certified mail, return receipt requested, and it must include a HIPAA authorization under Section 74.052 so the defendant can review the relevant medical records.

Section 74.051(c) is the part that matters most for timing. Giving proper notice tolls, or pauses, the statute of limitations for 75 days following the date the notice is sent. In practical terms, if four months remain on the two-year clock when the notice goes out, the claimant now has four months plus an additional 75 days to get the lawsuit on file.

1. Send the written pre-suit notice to each defendant at least 60 days before filing, with the required medical authorization attached.
2. The 75-day toll attaches automatically from the date the notice is sent, adding that time to whatever remained on the two-year clock.
3. File the lawsuit within the extended window, once the 60-day waiting period has passed.

This notice requirement is procedurally strict, and a letter that is not sent correctly may not trigger the toll at all, one reason families benefit from involving a Texas medical malpractice lawyer well before the two-year mark.

Special Rules When the Negligent Provider is a Government Hospital

If the hospital or provider involved is a governmental entity, a separate notice requirement applies before a lawsuit can be filed. Under the Texas Tort Claims Act, Section 101.101, notice of the claim must reach the governmental unit within six months of the incident, unless that unit already has actual notice of the death, injury, or damage involved.

This six-month notice runs alongside, not in place of, the standard two-year deadline under Section 74.251, and both have to be satisfied independently. In the Houston area, that combination applies to claims involving institutions like the Harris Health System, which operates Ben Taub as a county hospital district, and UT Health Houston, a state entity. Naming these systems here says nothing about whether any specific facility did anything wrong. It only means a claim against either one has to clear both deadlines instead of one.

The Tort Claims Act also caps the damages recoverable against a governmental defendant, with the exact limits depending on whether the institution is classified as a state agency or a local governmental unit. We cover those limits in full in our guide to Texas medical malpractice damage caps.

What is the 10-Year Statute of Repose and When Does it Cut Off a Claim Entirely?

Even when an exception extends the two-year window, Texas law imposes a hard outer limit. Under Section 74.251(b), no medical malpractice claim can be brought more than 10 years after the date of the negligent act or omission, no matter what tolling or exception might otherwise apply.

A statute of repose is different from a statute of limitations. A limitations period can sometimes be paused or extended, the way the pre-suit notice adds 75 days, but a statute of repose is closer to a substantive cutoff. Once those 10 years pass, the right to sue is gone, and courts have recognized only limited exceptions to it, in narrow circumstances involving certain minors. The repose and the two-year limitation are separate deadlines. Both apply, and the earlier one usually controls.

Claims involving an implanted medical device, medication harm that develops slowly, or a condition not diagnosed until years after the treatment that caused it are the ones most likely to run into this wall. If your situation involves a long gap between treatment and diagnosis, talking with a medical malpractice lawyer early is the only reliable way to find out whether the repose period has already closed the door.

Do the Rules Change if the Injured Patient is a Child?

Yes, but the extension is narrower than most parents expect. Only a child who was under 12 years old at the time of the negligent act gets extra time under Section 74.251(a), and that extension runs only until the child’s 14th birthday, not until age 18. A child who was 12 or older when the negligent act occurred has the same standard two-year window as an adult.

The 10-year repose still applies even to a child covered by the under-12 extension, though Texas courts have recognized narrow, fact-specific exceptions where applying the full repose period to a very young child would conflict with the state constitution’s open courts guarantee. Because that exception is narrow, parents should not assume it will apply without a lawyer’s review, and waiting until a child’s 14th birthday to act, even when the extension does apply, can mean losing years of investigation time and letting evidence disappear.

What Happens if You Miss the Texas Medical Malpractice Deadline?

A lawsuit filed after the two-year period has run, without a valid toll or exception in place, will almost certainly be dismissed, and the claim is barred for good. The defendant’s attorneys will move to dismiss on limitations grounds, the court will grant it, and no amount of evidence about what actually happened will matter at that point.

Protecting a claim before that happens usually means moving quickly on three fronts:

1. Contact a medical malpractice lawyer as soon as a problem is suspected, well before the deadline feels close.
2. Preserve the medical records and any related documentation before they can be lost or altered.
3. Allow real time for a qualified expert to review the case and for the Chapter 74 pre-suit notice process to run its course.

The two-year window can feel long at first, but gathering records, securing a qualified medical expert, and sending the pre-suit notice all take real time before a case is ready to file. In one of the firm’s cases, a failure to diagnose a cardiac condition led to a $19.75 million recovery for the family, made possible in part because the claim was filed while the evidence was still fresh and the deadline had not yet closed. Past results do not guarantee a similar outcome, but they show why acting early matters.

Steps to Protect Your Rights Before the Deadline

The most important thing an injured patient or their family can do after a suspected medical error is reach out to a medical malpractice attorney early enough to investigate the case, gather the evidence, and send the required pre-suit notice long before the filing deadline arrives.

1. Request and preserve the complete medical records related to the treatment in question.
2. Write down a detailed timeline of what happened while the details are still fresh.
3. Keep any written communications with the providers or the facility involved.
4. Contact a Texas medical malpractice attorney well before the two-year mark, not after it starts to feel urgent.
5. Allow time for a qualified expert to review the case and for the mandatory 60-day pre-suit notice window to run.

Texas also requires a separate expert report served on each defendant, a deadline set by Section 74.351 that runs 120 days after that defendant’s answer to the lawsuit, not 120 days from when the case was filed. Missing it results in dismissal with prejudice, and it shapes how quickly the investigation has to begin once a case is filed.
