The 120-day expert report that can end a Texas health care case
Texas procedure · Last verified August 17, 2026
Most procedural deadlines cost you a motion. This one costs you the case. In a Texas health care liability claim, the claimant must serve an expert report within 120 days of each defendant's original answer, and the consequence of not doing so is written into the statute as a command to the court: award fees, and dismiss with prejudice.
It is also a two-sided deadline. The defendant who does not object in time waives every objection.
The 120 days, and what starts them
CPRC § 74.351(a):
In a health care liability claim, a claimant shall, not later than the 120th day after the date each defendant's original answer is filed or a later date required under Section 74.353, serve on that party or the party's attorney one or more expert reports, with a curriculum vitae of each expert listed in the report for each physician or health care provider against whom a liability claim is asserted. The date for serving the report may be extended by written agreement of the affected parties.
Three things about the trigger. It runs from each defendant's original answer, not from filing suit, so a case with defendants answering on different dates has different deadlines running at once — and a defendant added later starts a fresh 120 days. It is a service deadline, not a filing deadline. And the report never travels alone: the CV goes with it.
The one consensual escape is in the last sentence. The parties may extend by written agreement, and § 74.351(r)(1) narrows who may agree — "affected parties" means the claimant and the provider "directly affected," not every party in the case.
The defendant's 21 days
The same subsection puts a clock on the other side, and it is easy to miss because it sits at the end of a long sentence:
Each defendant physician or health care provider whose conduct is implicated in a report must file and serve any objection to the sufficiency of the report not later than the later of the 21st day after the date the report is served or the 21st day after the date the defendant's answer is filed, failing which all objections are waived.
Twenty-one days from the later of two events, and the sanction is total: all objections are waived. A defendant who receives a thin report and sits on it has accepted it.
What happens if the report does not come
CPRC § 74.351(b) does not give the court discretion:
If, as to a defendant physician or health care provider, an expert report has not been served within the period specified by Subsection (a), the court, on the motion of the affected physician or health care provider, shall, subject to Subsection (c), enter an order that: (1) awards to the affected physician or health care provider reasonable attorney's fees and costs of court incurred by the physician or health care provider; and (2) dismisses the claim with respect to the physician or health care provider, with prejudice to the refiling of the claim.
"Shall," two mandatory consequences, and dismissal that bars refiling. Note that the court acts on the motion of the provider — this is not something that happens automatically on day 121, which in practice means a late report served before any motion is filed is a different situation from no report at all.
The one 30-day cure, and what it is for
CPRC § 74.351(c) is narrower than it is usually described:
If an expert report has not been served within the period specified by Subsection (a) because elements of the report are found deficient, the court may grant one 30-day extension to the claimant in order to cure the deficiency. If the claimant does not receive notice of the court's ruling granting the extension until after the applicable deadline has passed, then the 30-day extension shall run from the date the plaintiff first received the notice.
Read the condition. The extension exists for a report that was served and found deficient. It is discretionary ("may"), it is available once, and it is thirty days. The second sentence is a practical protection: if the order granting it arrives late, the thirty days runs from receipt of notice rather than from the ruling.
What counts as an expert report
CPRC § 74.351(r)(6) defines it, and the definition is the test:
"Expert report" means a written report by an expert that provides a fair summary of the expert's opinions as of the date of the report regarding applicable standards of care, the manner in which the care rendered by the physician or health care provider failed to meet the standards, and the causal relationship between that failure and the injury, harm, or damages claimed.
Three elements — standard of care, how the care fell short, and causation — and the standard for challenging it is set by § 74.351(l):
A court shall grant a motion challenging the adequacy of an expert report only if it appears to the court, after hearing, that the report does not represent an objective good faith effort to comply with the definition of an expert report in Subsection (r)(6).
Two flexibilities worth knowing. Under § 74.351(i), a claimant "may satisfy any requirement of this section for serving an expert report by serving reports of separate experts regarding different physicians or health care providers or regarding different issues," and nothing requires a single expert to address everything. Under § 74.351(j), nothing requires a report "regarding any issue other than an issue relating to liability or causation."
The discovery stay
The report is a gate on the case, not just on the claim. CPRC § 74.351(s):
Until a claimant has served the expert report and curriculum vitae as required by Subsection (a), all discovery in a health care liability claim is stayed except for the acquisition by the claimant of information, including medical or hospital records or other documents or tangible things, related to the patient's health care through: (1) written discovery as defined in Rule 192.7, Texas Rules of Civil Procedure; (2) depositions on written questions under Rule 200, Texas Rules of Civil Procedure; and (3) discovery from nonparties under Rule 205, Texas Rules of Civil Procedure.
So the claimant can still gather records — that is the point of the carve-outs — but the ordinary discovery machinery does not start. There is one more allowance in § 74.351(u): "after a claim is filed all claimants, collectively, may take not more than two depositions before the expert report is served."
Two. Collectively. Choose them carefully.
The report cannot be used as evidence
CPRC § 74.351(k) walls the report off from the merits:
Subject to Subsection (t), an expert report served under this section: (1) is not admissible in evidence by any party; (2) shall not be used in a deposition, trial, or other proceeding; and (3) shall not be referred to by any party during the course of the action for any purpose.
But that protection can be given away. § 74.351(t): "If an expert report is used by the claimant in the course of the action for any purpose other than to meet the service requirement of Subsection (a), the restrictions imposed by Subsection (k) on use of the expert report by any party are waived."
Using your own report tactically hands it to the other side.
How Texas compares to the federal rules
| Texas | Federal | |
|---|---|---|
| Pre-merits expert gate | yes, CPRC § 74.351 | none in the civil rules |
| Deadline | 120 days after each defendant's original answer | expert disclosure on the scheduling order |
| Extension by agreement | written agreement of the affected parties | stipulation, subject to the court |
| Consequence of missing it | mandatory dismissal with prejudice plus fees | exclusion of the expert, at most |
| Cure period | one 30-day extension, for a deficient report | no counterpart |
| Defendant's objection deadline | 21 days, or all objections waived | no counterpart |
| Standard on a challenge | objective good faith effort to comply with the definition | Rule 702 reliability |
| Discovery before the gate | stayed, except records discovery and two depositions | proceeds normally |
| Report admissible at trial | no, unless the claimant waives | expert reports generally inadmissible hearsay |
| Separate experts for separate issues | expressly allowed | allowed |
The federal rules have nothing like this. An expert failure in federal court is an evidentiary problem resolved near trial; in a Texas health care case it is a dispositive problem resolved four months in.
A short checklist
- Diary 120 days from each defendant's answer separately. They are not one deadline.
- Serve the CV with the report. The statute requires both.
- Get any extension in writing, and check that everyone signing is an "affected party."
- If you are a defendant, diary 21 days from the later of the report or your answer — silence waives every objection.
- Cover all three elements: standard of care, how the care fell short, and causation.
- Use separate experts where one cannot credibly cover everything.
- Plan discovery around the stay. Records discovery, written questions and non-party discovery are open; nothing else is.
- Spend your two depositions deliberately. That is the collective limit before the report is served.
- Do not use the report for anything else. Doing so waives the inadmissibility protection for everyone.
