Background
Rosa Herrera sued Angel Gutierrez-Zacatenco after he rear-ended her at a stoplight in 2019. Gutierrez-Zacatenco admitted liability, leaving causation and damages for trial. His defense focused on whether Herrera’s claimed spinal injuries and later treatment instead arose, at least in part, from a similar 2017 automobile accident. Herrera had produced medical records from that earlier treatment in response to his discovery request. Defense experts relied on those records to conclude that some neck and arm complaints were not caused by the 2019 collision.
The records Herrera produced omitted three pages documenting her final 2017 visit and release at maximum medical improvement. Although an Align Med custodian certified that the produced documents were accurate copies, the district court excluded them because the set was incomplete and did not satisfy the certification procedure in NRS 52.325. The court then limited the defense experts’ testimony to prevent them from discussing opinions based on those records. It also barred evidence that Herrera’s treating physicians held medical liens, reasoning that the collateral-source rule applied. The jury awarded Herrera about $3.8 million, followed by roughly $1.66 million in attorney fees and $114,673 in costs. The district court denied a new trial and additionally relied on the defense’s failure to identify the records specifically in its pretrial disclosures.
The Court’s Holding
The en banc Nevada Supreme Court reversed for a new trial. Writing for the court, Justice Cadish held that NRS 52.325 governs a records custodian’s response to a subpoena but is not the exclusive method for authenticating medical records. Because Gutierrez-Zacatenco obtained these records from Herrera in discovery rather than by subpoenaing Align Med, Nevada’s general authentication rule, NRS 52.015, controlled. That rule asks whether the proponent supplied enough evidence for a reasonable juror to find that an item is what the proponent claims.
The defense cleared that threshold. Herrera produced her own treatment records, did not dispute that they reflected care she received, and treated them as genuine during expert depositions and motion practice. The documents carried Align Med letterhead and Herrera’s identifying information, while the custodian also attested to their accuracy. Their missing final report concerned weight, not threshold authenticity; the jury should have decided how incompleteness affected their value. The court stopped short of declaring every document produced in discovery automatically authentic, emphasizing that authentication remains fact-specific.
The court also held that the defense’s pretrial disclosure was deficient under NRCP 16.1(a)(3)(A)(iii), because catchall references did not specifically identify the exhibits expected at trial. But exclusion under NRCP 37(c)(1) was improper because the lapse was harmless: Herrera knew well before trial that the 2017 records were central to the causation defense, moved to exclude them, and questioned the experts about them. Finally, medical liens are obligations incurred by the plaintiff, not third-party compensation. Evidence of their existence therefore does not trigger the collateral-source rule and may be relevant to a treating provider’s bias. The trial court must assess that relevance on remand.
Key Takeaways
- NRS 52.325 is a subpoena-response procedure, not Nevada’s exclusive route for authenticating medical records. Records received from an opponent in discovery may be authenticated under NRS 52.015 through their source, distinctive characteristics, custodian evidence, and surrounding circumstances.
- An incomplete set can still be authentic. Once a proponent makes the modest prima facie showing, missing material ordinarily affects evidentiary weight for the jury rather than admissibility.
- NRCP 16.1 pretrial disclosures should name intended exhibits specifically. Still, NRCP 37(c)(1) does not permit automatic exclusion when a disclosure failure is harmless and the opponent had meaningful advance notice.
- A Nevada medical lien is not a collateral source. Its existence may be admitted to show a treating provider’s possible financial bias, subject to ordinary relevance analysis.
Why It Matters
The decision gives Nevada litigators a practical authentication path when a party produces its own medical records but later challenges their admissibility. Counsel should still secure a clean custodian certification and list each exhibit precisely, but the opponent’s production, use of the records in discovery, facial identifiers, and corroborating testimony can collectively satisfy NRS 52.015. A completeness defect should be framed for the jury rather than converted into an all-or-nothing bar.
For Las Vegas personal-injury practice, the ruling also restores medical-lien bias evidence to the normal relevance inquiry. The combined errors mattered because they removed the core of the defense causation case and may have changed a multimillion-dollar verdict. The Supreme Court vacated the fee-and-cost award along with ordering a new trial, underscoring that erroneous evidentiary restrictions can unwind both the merits judgment and substantial post-judgment exposure.
