California just changed the math on rideshare accident settlements. On June 25, 2026, Governor Newsom signed Senate Bill 623 — the Fair Medical Billing & Rideshare Safety Act — into law, bringing a sudden end to what was projected to be a $150 million political battle between Uber Technologies, Inc. and the Consumer Attorneys of California (CAOC). Starting January 1, 2027, the way medical liens are calculated and paid in Uber and Lyft accident claims will work differently than anything California injury victims have experienced before. If you were injured in a rideshare accident, or if you are navigating a pending claim that will settle after the effective date, understanding the SB 623 medical lien cap 70th percentile rideshare settlement 2027 framework could be the difference between a settlement that actually changes your life and one that disappears before you can use it.
What Is SB 623 and Why Does It Exist?
The Fair Medical Billing & Rideshare Safety Act emerged from a political compromise between two powerful California interests. Uber and Lyft, facing aggressive consumer-protection ballot measures that had been projected to ignite a $150 million campaign war, negotiated with the Consumer Attorneys of California to support SB 623 as an alternative. Governor Newsom signed the bill on June 25, 2026, and it was chaptered by the Secretary of State the same day, ending the ballot-measure fight over rideshare accident liability, medical lien practices, and personal injury recoveries. The result is a statute that limits how much medical providers can recover from rideshare accident settlements through liens — a practice that, under the prior system, routinely consumed 50% or more of a victim’s gross settlement before a single dollar reached the injured person. SB 623 also imposes annual background-check requirements on rideshare drivers and restricts certain financial relationships between personal injury attorneys and medical providers.
The new law adds Health & Safety Code §1668.3, which establishes a data-driven ceiling on medical lien recovery in transportation network company (TNC) accident claims. The core mechanism is the SB 623 medical lien cap 70th percentile rideshare settlement 2027 standard: medical providers asserting a lien against a rideshare settlement can recover no more than the 70th percentile of reasonable and customary charges for the services rendered in the relevant geographic market. This is not a flat-dollar cap. It is a market-benchmarked limit tied to real pricing data, which makes it both more defensible and more enforceable than prior lien reform attempts in California.
It is also worth noting the insurance landscape that existed when SB 623 was signed. As of January 1, 2026, California had already reduced the mandatory uninsured/underinsured motorist (UM/UIM) coverage on rideshare trips from $1 million to $60,000 per person and $300,000 per incident under Senate Bill 371, signed in October 2025. That reduction makes the lien reforms in SB 623 all the more significant for victims whose recoveries are now bounded by lower available insurance limits in many cases.

The 70th Percentile Framework Explained
How the 70th Percentile Is Calculated
The 70th percentile benchmark is not an arbitrary number. It means that a medical provider’s lien is capped at the charge level at which 70% of comparable providers in the same geographic area charge less — and 30% charge more. In practical terms, this eliminates the ability of lien-based providers (sometimes called “letter of protection” providers) to bill at rates far exceeding market norms specifically because they know a personal injury settlement will fund payment. Before SB 623, providers working on letters of protection routinely billed at 200% to 400% of Medicare rates, creating inflated lien balances that swallowed victim recoveries. The 70th percentile standard anchors lien amounts to what the broader provider market actually charges, not what a litigation-focused provider chooses to bill.
The benchmark is calculated using commercially available claims databases — the same data sources that health insurers and workers’ compensation carriers already rely on to evaluate reasonable and customary charges. For each medical procedure performed on the rideshare accident victim, the relevant CPT code is matched against the geographic database to identify the 70th percentile charge. The sum of those procedure-level caps is the maximum the provider can assert as a lien against the settlement. If a provider billed above that level, the excess is unenforceable under Health & Safety Code §1668.3.
What Counts as a “Medical Lien” Under the Statute
SB 623 defines a covered medical lien broadly to include any agreement under which a healthcare provider defers payment for treatment of a rideshare accident victim in exchange for a right to recover from the victim’s tort settlement, judgment, or arbitration award. This encompasses traditional letters of protection, hospital lien act claims asserted by California-licensed hospitals, and assignment-of-benefits arrangements structured to achieve the same economic result. The statute does not apply to payments made by health insurance, Medicare, or Medi-Cal at the time of service — those programs have their own reimbursement and subrogation frameworks that SB 623 does not alter.
Before and After: Real Settlement Math Under SB 623
The $200,000 Settlement Example
Consider a rideshare accident victim who sustains moderate orthopedic injuries — a herniated disc requiring epidural injections and a course of physical therapy — and ultimately settles her Uber accident claim for $200,000. This falls squarely within the range where the majority of rideshare accident settlements land in 2026, with most cases resolving between $20,000 and $250,000 depending primarily on the severity of injuries sustained.
Under the pre-SB 623 system, her treating providers, working on letters of protection, billed a combined $95,000. After attorney fees of 33% ($66,000) and the full lien balance of $95,000, she would have taken home approximately $39,000 from a $200,000 settlement — less than 20 cents on the dollar.
Under SB 623, those same services, benchmarked to the 70th percentile of reasonable and customary charges in her county, produce a maximum lien of $41,000. After the same 33% attorney fee and the capped lien balance, she takes home approximately $93,000 — more than double her pre-reform recovery from the identical gross settlement. The law does not change what Uber pays. It changes how much of that payment actually reaches the person who was hurt.
High-Severity Case: $750,000 Settlement
In a more serious rideshare accident involving spinal surgery, the numbers are even more dramatic. A victim who undergoes a two-level cervical fusion after a Lyft collision might face provider billings of $400,000 or more under the letter-of-protection model. If the case settles for $750,000, the pre-reform math could leave the victim with less than $100,000 after fees and liens — an outcome that bears no relationship to the severity of the harm suffered.
Under SB 623, the same surgical services benchmarked to the 70th percentile might produce a maximum lien of $175,000. After a 33% contingency fee of $247,500 and the capped lien of $175,000, the victim retains approximately $327,500 — a recovery that actually reflects the seriousness of a life-altering spinal injury. The statute does not limit what victims can recover. It limits what providers can extract from what victims recover.
Critical Timing: When Does SB 623 Apply to Your Rideshare Claim?
The January 1, 2027 Effective Date Rule
SB 623 was signed on June 25, 2026, but the medical lien cap provisions do not take effect until January 1, 2027. The operative trigger is the date of settlement, judgment, or arbitration award — not the date of the accident. A rideshare accident that occurred in early 2026 but resolves through settlement on or after January 1, 2027 will be governed by the new lien cap framework. An accident that occurred in December 2026 but settles before the end of that year will not benefit from SB 623’s lien limits.
This timing rule has significant strategic implications for victims and their attorneys. Cases that are close to resolution in the final months of 2026 may benefit from a deliberate decision to allow settlement negotiations to extend into 2027, particularly where accumulated medical liens are large relative to the expected gross recovery.
Impact on Pending Cases and Claim Strategy
For victims with pending rideshare accident claims as of mid-2026, the calculus around settlement timing changed materially the moment SB 623 was signed. Attorneys who previously had limited leverage over inflated lien balances now have a statutory framework arriving on January 1, 2027 that will do the work of lien negotiation automatically. Providers who hold large lien balances on pending cases are aware of this dynamic and may be more willing to negotiate voluntary reductions before the effective date than they would have been before the law passed.
Victims should discuss with their attorneys whether delaying settlement into 2027 — or accelerating settlement before January 1, 2027 in cases where voluntary lien reductions can be obtained today — produces the better net outcome given the specific facts of their claim.
How SB 623 Changes Claim Valuation and Strategy for Rideshare Victims
Reconsidering Gross Settlement Targets
One of the less obvious effects of SB 623 is that it changes the relationship between gross settlement value and net victim recovery in a way that makes lower gross settlements more acceptable. Before lien reform, a $300,000 gross settlement with $140,000 in liens and $99,000 in attorney fees left a victim with $61,000. Under SB 623, a $200,000 gross settlement with the same underlying treatment but a capped lien of $60,000 and $66,000 in attorney fees leaves the victim with $74,000 — a better outcome from a smaller headline number.
This has practical consequences for how rideshare accident attorneys should counsel clients on settlement offers and for how Uber and Lyft adjusters will likely approach valuations. The gross-settlement arms race that characterized high-lien cases under the prior system — where both sides inflated their numbers to account for the lien overhang — may give way to more efficient negotiations focused on actual damages rather than lien arithmetic.
Enforcing the Cap: What the Statute Requires
Health & Safety Code §1668.3 places enforcement obligations on both providers and settling parties. A medical provider asserting a lien must, at the time of asserting the lien, disclose the CPT codes billed, the amounts billed, and the data source used to establish that the amounts comply with the 70th percentile standard. If a provider fails to make this disclosure, the lien is voidable at the election of the settling party. If a provider asserts a lien amount that exceeds the 70th percentile benchmark, the victim or their attorney may challenge the excess in a noticed motion in the superior court with jurisdiction over the underlying personal injury action.
The statute also creates a private right of action for victims damaged by a provider’s knowing assertion of an inflated lien, with remedies including the excess lien amount, attorney fees, and a civil penalty. This enforcement structure is designed to make compliance self-executing: providers who ignore the cap face liability that exceeds any benefit from overbilling.
Frequently Asked Questions About SB 623 and Rideshare Medical Liens
FAQ 1: Does SB 623 apply if my Uber or Lyft accident happened in December 2026 but my case settles in March 2027?
Yes. The medical lien cap provisions of SB 623 are triggered by the date of settlement, judgment, or arbitration award — not the date of the accident. If your rideshare accident occurred at any point before January 1, 2027, but your case resolves on or after that date, the 70th percentile lien cap applies to all medical liens asserted against your recovery. The date of the accident is relevant to questions of liability, damages, and the insurance coverage in force at the time of the trip, but it does not determine whether SB 623’s lien framework governs the distribution of your settlement proceeds.
FAQ 2: If my rideshare accident medical bills were paid by Medi-Cal or Medicare, does SB 623 limit what those programs can recover?
No. SB 623’s medical lien cap applies specifically to deferred-payment arrangements — letters of protection, hospital lien act claims, and similar structures under which a provider agrees to wait for payment from a personal injury settlement. When Medi-Cal or Medicare pays for your treatment at the time of service, those programs have independent rights of reimbursement and subrogation governed by federal and state law that SB 623 does not alter. The Medi-Cal and Medicare reimbursement frameworks already impose their own limits on recovery — typically tied to the amounts those programs actually paid rather than provider billed charges — so the practical gap between the old system and SB 623 is smaller for government-pay patients than for patients who treated on letters of protection.
FAQ 3: How much money can I actually expect to save under SB 623 compared to the old system?
The answer depends on how aggressively your treating providers billed under the letter-of-protection model. In cases where providers billed at 200% to 300% of reasonable and customary charges — which was not unusual in high-volume personal injury medical practices before SB 623 — victims can expect the lien cap to reduce their total lien burden by 40% to 60%. On a $200,000 settlement with $90,000 in pre-reform liens, that translates to $36,000 to $54,000 in additional money reaching the injured person. On larger cases, the savings are proportionally greater. Keep in mind that the majority of rideshare accident settlements in 2026 fall between $20,000 and $250,000, meaning SB 623’s lien reforms will have their most significant impact on the cases where victims can least afford to see their recoveries consumed by medical billing.
FAQ 4: Does SB 623 apply to accidents in Uber Pool or Lyft Shared rides, or only to standard solo rideshare trips?
SB 623 applies to any accident involving a transportation network company vehicle as defined under California Public Utilities Code §5431 — the same statutory definition that governs Uber and Lyft’s insurance obligations. That definition covers all TNC-facilitated trips regardless of whether the ride is a solo booking, a pooled service, or any other trip configuration offered through the platform’s app. If you were a passenger, pedestrian, or other road user injured in a collision involving an active TNC vehicle, the SB 623 lien framework will apply to your settlement if it resolves on or after January 1, 2027.
FAQ 5: Will SB 623 affect how Uber and Lyft negotiate settlements, or just how medical providers handle liens?
Both. The direct and immediate effect of SB 623 is on the medical provider side — lien amounts will be capped, and providers must comply with disclosure and benchmark requirements or face enforcement consequences. But the indirect effect on Uber and Lyft’s settlement behavior is real and already being discussed among rideshare defense practitioners. When adjusters know that a victim’s net recovery from any given gross settlement will be substantially higher than it was before lien reform, the implicit pressure to offer inflated gross settlements to overcome lien overhang disappears. The result may be a recalibration of gross settlement values toward amounts that more accurately reflect actual damages — which is, in theory, what the tort system is supposed to produce. Victims and their attorneys should be alert to this dynamic and prepared to document damages comprehensively to support gross settlement demands that reflect the full value of their injuries independent of lien arithmetic.
