California Governor Gavin Newsom signed Senate Bill 623 on June 25, 2026, marking the most significant shift in how rideshare accident medical damages are calculated in the state’s courts in recent memory. The law, which took effect immediately upon signing, introduces a capped lien-recovery framework tied to FAIR Health benchmark pricing, expands driver background check requirements, and mandates annual re-screening of all active Transportation Network Company (TNC) drivers starting in 2026. For anyone injured in an Uber or Lyft accident in California, understanding SB 623 rideshare medical damages rules is now essential to estimating what a settlement may actually be worth.
What SB 623 Actually Changes About Medical Damages in Rideshare Settlements
The core of SB 623 focuses on a long-contested issue in personal injury litigation: the gap between what a medical provider charges on a lien, what insurance actually reimburses, and what a jury ultimately sees as the “reasonable value” of medical treatment. Before SB 623, California plaintiffs in rideshare accident cases could introduce full billed charges — sometimes three to five times what Medicare or private insurers would pay — as evidence of damages. Defense attorneys for Uber and Lyft routinely challenged these figures, and juries were left to sort out wildly divergent numbers.
Under SB 623 rideshare medical damages rules, lien-based medical providers — those who agree to treat patients and defer billing until a settlement is reached — can no longer recover amounts that exceed the applicable FAIR Health benchmark for that procedure in the relevant California geographic region. FAIR Health is a nonprofit that maintains a comprehensive database of privately billed and paid health care claims; its benchmarks represent median market rates, not artificially inflated list prices.
Critically, SB 623 does not cap what a plaintiff can claim if treatment was paid through traditional insurance. If your health insurer paid your hospital bills after an Uber accident, you retain the right to claim the full reasonable value of treatment as part of your damages — the FAIR Health cap applies only to the lien-side of the ledger. This distinction matters enormously when you compare how different injury victims will fare under the new framework.
How the FAIR Health Cap Works in Practice
Imagine a rideshare passenger suffers a fractured wrist requiring surgery. The treating orthopedic surgeon, working on a lien, bills $42,000. The FAIR Health 80th-percentile benchmark for that procedure in Los Angeles County is $28,500. Under SB 623, the maximum lien recovery against any rideshare settlement is $28,500 for that line item — not the billed amount. The plaintiff’s attorney negotiating with Uber or Lyft’s insurer now works from that capped figure rather than the inflated charge. This narrows the damages calculation but eliminates a significant source of uncertainty that previously caused cases to stall in litigation for years.
SB 623 Driver Screening Requirements: What Changes in 2026
The second pillar of SB 623 is an expansion of criminal background check requirements for TNC drivers — and the introduction of mandatory annual re-screening for all active drivers beginning in 2026. Previous California law required a background check at initial onboarding, but there was no statutory obligation for Uber or Lyft to re-run those checks on a rolling basis. A driver could acquire a disqualifying conviction after being approved and continue driving passengers legally.
SB 623 adds several categories of offenses to the existing disqualification list under California Public Utilities Code Section 5445.2, including convictions for vehicular manslaughter, aggravated assault with a vehicle, and certain drug trafficking offenses that previously fell into a gray zone. The California Legislature’s official bill text specifies that TNCs must use a third-party background screening vendor with access to court records in all 50 states and must certify compliance with the PUC annually.
Why Annual Re-Screening Matters for Negligent Hiring Claims
For personal injury attorneys and accident victims, the annual re-screening requirement creates a new and meaningful evidence avenue. If a TNC fails to conduct the required annual background check and a driver with a post-hiring disqualifying conviction causes an accident, the plaintiff can now point to a specific statutory violation as evidence of negligent hiring or retention. Before SB 623, negligent hiring claims against Uber and Lyft in California required plaintiffs to piece together common-law duty arguments without a clear legislative standard to anchor them.
This is a significant shift. SB 623 rideshare medical damages cases that also involve a driver who should have been disqualified under the new screening rules may carry substantially higher settlement values, because the TNC’s exposure on the negligent hiring claim adds an independent liability theory beyond ordinary vicarious liability. If you are comparing a rideshare accident claim to a standard vehicle collision, a car accident settlement calculator can help illustrate how the presence of a corporate negligence theory changes the overall damages picture.
SB 623 vs. the Failed Uber Ballot Initiative: Understanding the Difference
Context matters here. SB 623 did not emerge from a vacuum. Throughout 2025 and into 2026, Uber and Lyft funded a $150 million ballot campaign — ultimately unsuccessful — that would have imposed far more sweeping caps on medical damages in all personal injury cases involving TNCs, not just the lien-side limitations that SB 623 addresses. That initiative failed to qualify for the November 2026 ballot after the California Supreme Court upheld an attorney general’s title and summary that critics argued was prejudicial to TNC interests.
SB 623 represents the legislative compromise that emerged from that standoff. Trial lawyers agreed to the FAIR Health lien cap in exchange for the expanded background check requirements and the annual re-screening mandate — provisions that Uber and Lyft initially opposed but ultimately accepted as the price of avoiding continued ballot initiative uncertainty. The result is a law that is narrower than what Uber originally sought and narrower than what plaintiff advocacy groups had feared, but one that meaningfully restructures SB 623 rideshare medical damages calculations going forward.
It is also worth distinguishing SB 623 from SB 371, a separate 2026 California law addressing uninsured and underinsured motorist coverage reductions in rideshare policies — a topic we have covered separately on this site. The two bills operate in different legal domains: SB 371 touches insurance policy structure, while SB 623 touches how damages are calculated and what hiring standards TNCs must meet.

How SB 623 Affects Serious and Catastrophic Injury Cases
The FAIR Health lien cap has its most pronounced effect on cases involving moderate injuries treated almost entirely on medical liens — the bread and butter of high-volume rideshare injury practices. For catastrophic injuries, the calculus is different. A passenger who sustains a traumatic brain injury in an Uber accident, for example, will typically have a combination of lien-based treatment, private insurance-paid treatment, and future care needs. The FAIR Health cap governs only the lien portion; future medical expenses and insurance-paid past treatment remain uncapped.
For TBI victims specifically, the non-economic damages — pain and suffering, loss of enjoyment of life — often dwarf the medical special damages regardless of how the lien question is resolved. Using a brain injury calculator can help TBI victims and their families model the full scope of a potential settlement before entering negotiations with Uber or Lyft’s insurance carrier. SB 623 rideshare medical damages rules do not affect non-economic damages caps, which remain governed by California’s existing legal framework outside the medical malpractice context.
Fatal Rideshare Accidents Under the New Framework
Wrongful death claims arising from rideshare accidents are similarly unaffected by the FAIR Health lien cap in most practical scenarios, because the decedent’s own medical expenses form only a portion of the wrongful death damages claimed by surviving family members. Loss of financial support, loss of companionship, and pre-death pain and suffering calculations remain outside SB 623’s scope. Families evaluating a fatal rideshare accident claim can use a wrongful death calculator to understand the full range of recoverable losses before accepting any settlement offer from a TNC insurer. The new negligent hiring evidence avenue under SB 623 may be especially relevant in fatal cases where the driver’s background is at issue.
What Rideshare Accident Victims Should Do Now
If you were injured in a California Uber or Lyft accident in 2026, SB 623 shapes your case in at least two concrete ways. First, if you are treating on a medical lien, your provider is now legally limited in what it can recover against your settlement — which means the net recovery you take home after lien payoff may be higher than it would have been under the old system, even if gross settlement amounts compress somewhat. Second, your attorney should investigate whether the driver passed the required annual re-screening under the new PUC standards, because a failure there opens an independent negligent hiring theory that can meaningfully increase TNC exposure.
The Nolo personal injury resource library provides useful background on how California damages law works generally, but SB 623 introduces TNC-specific rules that require attention to the bill’s precise language. Documenting your medical treatment carefully — distinguishing between lien-based care and insurance-paid care from the outset — will help your legal team calculate your damages correctly under the new framework. Using a personal injury settlement calculator as a starting point can help you understand the range of outcomes before you consult with legal counsel.
SB 623 rideshare medical damages rules represent a genuine change in the California litigation landscape — not a dramatic overhaul, but a meaningful recalibration that every rideshare accident victim, attorney, and insurer must now account for in every case filed from this point forward.
Frequently Asked Questions About SB 623 and Rideshare Medical Damages
Does SB 623 cap all my medical damages in a rideshare accident case?
No. SB 623 rideshare medical damages rules cap only the amount that lien-based medical providers can recover against your settlement. If your treatment was paid by private health insurance, Medicare, Medi-Cal, or out of pocket, the FAIR Health benchmark cap does not apply to those amounts. Non-economic damages — pain and suffering, emotional distress, loss of enjoyment of life — are entirely outside SB 623’s scope and are not capped by this law.
What is the FAIR Health benchmark and how is it determined for my injury?
FAIR Health is an independent nonprofit organization that maintains a national database of health care claims submitted by private insurers. For any given medical procedure, FAIR Health calculates benchmark prices at various percentile levels (50th, 80th, 95th) based on actual billed and paid amounts in a specific geographic region. Under SB 623, the applicable benchmark for lien recovery in California rideshare cases is determined by the procedure code and the county where treatment occurred. Your attorney or medical billing expert can pull the specific FAIR Health benchmark for each procedure in your treatment record.
How does SB 623’s annual driver re-screening requirement help my accident claim?
If Uber or Lyft failed to conduct the required annual background re-screening of the driver who injured you, and that driver had a post-hiring disqualifying conviction, SB 623 gives your attorney a statutory hook for a negligent hiring or negligent retention claim against the TNC. This is a separate liability theory from standard vicarious liability and can significantly increase the TNC’s exposure in settlement negotiations. Evidence of re-screening failure — or the absence of documentation showing a clean re-screen — should be preserved and requested early in the discovery process.
Is SB 623 the same as the Uber ballot initiative that failed in 2026?
No. The failed 2026 Uber-funded ballot initiative would have imposed much broader caps on medical damages in all TNC-related personal injury cases and was defeated after the California Supreme Court upheld an attorney general’s title and summary that critics said was unfavorable to TNC interests. SB 623 is a legislative compromise that emerged from that standoff. It applies the FAIR Health cap only to lien-based recovery, not to all medical damages, and it adds driver screening requirements that the ballot initiative did not include. The two measures are legally and structurally distinct.
Does SB 623 apply to accidents that happened before June 25, 2026?
SB 623 took effect upon the Governor’s signature on June 25, 2026. Cases arising from accidents that occurred before that date are generally governed by the law in effect at the time of the injury, though the specific application of SB 623 to pending litigation may depend on how the courts interpret its effective date language in relation to active cases. If your accident occurred before June 25, 2026, you should discuss with a qualified California attorney whether the new FAIR Health lien cap or the expanded screening standards affect your specific case posture.
