Will SB 623 Reduce Personal Injury Case Values in California?

Key Takeaways

• SB 623, the 2026 “Fairness in Injury Damages” initiative backed by Uber and other TNCs, would cap admissible medical bills at the 70th percentile of FAIR Health billed charges for lien-based providers, directly suppressing economic damages in most personal injury cases.
• The bill applies to motor-vehicle and premises liability cases arising on or after January 1, 2027, and restricts what juries see regarding medical expenses and write-offs, creating downward pressure on case value across soft tissue injuries, moderate injury type claims, and even catastrophic injuries.
• Average personal injury settlements in California currently range from $21,000 to $55,000; SB 623 could compress those bands by 20–40% for moderate cases, forcing PI firms to rethink the valuation process from intake to trial.
• Firms will need more volume, better-qualified leads, and stronger branding to maintain revenue if the average personal injury settlement drops.
• Walker Advertising helps California personal injury firms adapt by delivering high-intent, bilingual leads and marketing support tailored to the changing PI landscape.

Introduction: Why SB 623 Matters for California Personal Injury Case Valuation

SB 623 is a California bill working through the 2025–2026 legislative session, heavily supported by Uber, Lyft, and insurance-aligned interests. Its stated goal is to curb “inflated medical bills” and lower auto insurance premiums. In practice, the bill would limit the medical expenses a plaintiff can present at trial by capping recoverable past medical from lien-based providers at the 70th percentile of regional billed charges and making anything above that inadmissible. The value of a personal injury case involves assessing economic and non-economic damages, and SB 623 directly reshapes that equation.

For personal injury attorneys, the implications are serious. Over 95% of personal injury cases settle before trial, which means insurer valuation models-not just jury verdicts-will recalibrate around these new limits. This article breaks down what SB 623 changes, how it affects personal injury case valuation, and what your firm can do now to stay ahead. As we detailed in our analysis of what the Uber initiative in California means for your personal injury firm, this legislation is a business-model challenge as much as a legal one.

What SB 623 Actually Changes in California Personal Injury Claims

SB 623 introduces several evidentiary and damages-related changes that would reshape how personal injury claims are built and valued in California:

• Medical bill caps via FAIR Health benchmarks. Admissible past medical expenses from lien-based providers are capped at the 70th percentile of billed charges in the relevant geographic area. Amounts above that threshold are declared void and inadmissible. Economic damages cover tangible financial losses from injuries, and this cap directly shrinks the specials column.
• Lien-based provider restrictions. The bill targets providers who treat patients under liens, letters of protection, or payment arrangements contingent on a legal claim. Health insurance-paid amounts (private, Medi-Cal, Medicare) are excluded. This parallels the logic of Howell v. Hamilton Meats (2011) but codifies and expands it.
• Tighter billing requirements. Medical bills must be itemized at the procedure-code level (CPT, HCPCS, ICD). Defendants can challenge deficient billing, and plaintiffs get 30 days to cure. Non-economic damages compensate for intangible suffering and emotional distress, but they often anchor to these specials.
• Limited exceptions. Plaintiffs can exceed the cap only by showing, with clear and convincing evidence, that treatment was “exceptionally rare or highly specialized.” That motion must be decided by the court before trial-a high bar in rare cases.
• Prospective application. The bill applies to accidents on or after January 1, 2027, meaning attorneys must manage a split docket. General damages cover loss of enjoyment of life, punitive damages may be awarded for extreme recklessness or intentional harm, and California follows a pure comparative negligence rule regarding compensation-none of that changes under SB 623, but the foundation those damages rest on gets narrower.

Claims often begin with a demand letter to the insurance company. Under SB 623, that demand letter will carry less weight when medical specials are capped.

How SB 623 Could Reduce Economic Damages: Medical Expenses, Lost Wages, and Beyond

Under current california law, plaintiffs often anchor case value using gross billed medical expenses, even when insurers or Medi-Cal pay far less. SB 623 eliminates that anchoring for lien-based treatment. Here is how economic losses get compressed across different scenarios:

• Moderate car accident cases. Car accident settlements typically range from $20,000 to $30,000. In a rear-end collision with $15,000 in billed physical therapy and imaging from a lien provider, the 70th percentile cap might reduce admissible specials to $10,000. Lost wages of $4,000 and a 2x multiplier would push the settlement value from roughly $55,000 down to $38,000. Lost wages are included in economic damages for missed work, and lost wages increase the value of personal injury claims-but that uplift shrinks when specials shrink.
• Motorcycle and rideshare crashes. Motorcycle accident settlements can reach $50,000 to $150,000, and severe injuries involving hospital stays, prescription medications, and surgery often generate massive lien-based bills. Under SB 623, those bills get capped, reducing the base that ultimately determine overall case value.
• Slip and fall claims. Slip and fall claims usually settle between $15,000 and $50,000. Premises liability cases involving rideshare pickup zones or TNC-related incidents may fall within SB 623’s scope. Medical malpractice claims average around $679,000 in California-unaffected by SB 623-but general PI cases face real exposure.
• Catastrophic spinal injury example. A 32-year-old rideshare passenger with a C5–C6 spinal injury might have $400,000 in past medical expenses from lien providers. Under SB 623, admissible specials could drop to $250,000–$300,000. Future medical expenses are included in personal injury claims, and future medical treatment projections remain viable, but the anchor shifts. Key factors include severity of injuries and medical costs, and medical treatment timelines affect the accurate valuation of claims-all of which matter more when the admissible specials shrink.
• Soft tissue and minor injuries. For a back injury with a few thousand dollars in chiropractic bills and imaging, SB 623 could tip the injury claim below the threshold where litigation makes economic sense. Insurance policy limits cap the maximum recovery amount, and policy limits cap the maximum recovery from insurance claims, so when specials drop and limits are low, the math stops working. Lost wages increase claim value if future income is affected, but many soft tissue cases involve workers who miss work for only days, not months.

Medical expenses include future treatment costs in claims, but life care planners and vocational experts will need to build projections independent of inflated past specials to maintain credibility.

Non Economic Damages Under SB 623: The Quiet Squeeze on Pain and Suffering

In most personal injury cases, non economic damages are valued through a multiplier applied to medical expenses and sometimes lost wages. California juries award an average of $150,000 in non economic damages, but that figure reflects cases where medical specials provide robust anchoring. Pain and suffering damages are calculated using multipliers-typically 1.5x to 5x depending on severity-and when the base number contracts, the multiplied result follows.

Even if SB 623 does not impose a hard cap on pain and suffering, the practical effect is similar. Defendants will argue that the legislature’s intent was to curb inflated damages, and juries may internalize that framing. Emotional distress, physical pain, and intangible factors like loss of enjoyment of life become harder to quantify at historically high levels when the economic foundation is thinner.

• Chronic pain and mild TBI. In cases where non economic damages dominate-think persistent headaches, cognitive difficulties, or psychological injuries-SB 623’s rhetoric makes juries more skeptical. The trial value of these claims drops even without a statutory cap.
• Severe brain injury cases can result in multi-million dollar awards, and catastrophic injuries involving brain damage, amputations, or severe burns will likely still command substantial non economic damages. But plaintiffs’ counsel will need stronger human-story evidence and expert testimony to overcome defense narratives anchored in SB 623’s legislative intent.
• Permanent disability and permanent impairment. Cases involving permanent effects-reduced earning capacity, lifelong physical limitations-still support significant non economic damages, but the injured person must present specific details and documentation that stand independent of billed specials. Permanent disability cases may need more robust vocational and life-care expert support.

Ripple Effects on Case Value: Settlement Dynamics and California Jury Verdicts

Insurance adjusters use formulas and software for payouts, and those algorithms will recalibrate once SB 623 is in effect. Insurance companies often offer lower initial settlements without legal help, and this dynamic will intensify as insurers point to statutory caps to justify lower reserves across their california cases portfolios.

• Settlement band compression. The vast majority of moderate-injury auto cases currently settle in predictable bands. Those bands will narrow. Cases that previously settled for $25,000 may see offers of $18,000–$20,000. Insurance companies consider liability when calculating settlements, and comparative fault combined with lower specials creates a compounding downward effect.
• Early california verdicts matter. Jury verdicts from 2028–2029 in Los Angeles, San Diego, and the Bay Area will set benchmarks. Defense counsel will use those early post-SB 623 outcomes to justify lower offers across all injury type categories. The national average for PI settlements may diverge further from California-specific data.
• Nuclear verdicts persist, but at higher cost. Severe injuries and catastrophic injuries will still produce verdicts reaching even millions of thousand dollars, but plaintiffs may need to try more cases to counterbalance a lower baseline. That increases litigation costs and risk. Strong evidence is vital to prove the other party’s fault, and evidence such as police reports and witness statements strengthens negotiation positions.
• Experienced attorneys maximize personal injury claim values significantly. Legal representation can increase settlement amounts by leveraging evidence-this becomes even more critical in a post-SB 623 environment. Liability affects the strength of a personal injury case, and the injured party with strong counsel will fare far better than those without.

Property damage documentation, wage-loss verification, and maximum medical improvement timing all become more strategically important when specials are capped.

Practice Management Impact: Intake, Case Mix, and Marketing in a Post–SB 623 World

SB 623 is not just a legal issue-it is a business-model issue. If average case value declines 20–30% for a significant portion of your California personal injury docket, the math changes fast.

• Tighter intake criteria. Firms will become more selective, focusing on clear liability, higher insurance policy limits, documented lost income, and loss of earning capacity. An injury case worth pursuing must clear a higher threshold.
• Case volume must increase. Stakeholder projections suggest firms may need 25–50% more cases to maintain current revenue. That means stronger pipelines and more efficient operations.
• Disproportionate impact on underserved communities. Spanish-speaking and working-class injury victims who often rely on rideshare services and lien-based medical care will be most affected. Culturally aligned legal marketing and bilingual outreach become essential for reaching these communities and ensuring access to justice.
• Marketing ROI shifts. Channels that deliver pre-qualified leads for serious auto, pedestrian, and catastrophic injuries become critical. Spending on lead generation for personal injury must be more targeted, not less.
• Higher-severity focus. Firms heavily dependent on low-to-moderate motor-vehicle cases with limited policy limits are most exposed. Many factors will push firms toward potentially higher-value practice segments as core revenue drivers.

Strategic Steps California PI Firms Can Take Now

The window between now and January 2027 is your preparation period. Here is a practical checklist:

• Audit your settled cases. Model how SB 623-style caps would have changed personal injury case worth and revenue across your last 2–3 years of motor-vehicle and rideshare matters.
• Update demand-letter templates. Rely less on gross medical specials and more on functional impairment, work impact, and credible future-care analysis that stays persuasive when billed charges are limited.
• Strengthen economic documentation. Standardized wage-loss forms, employer verifications, and treating-physician narratives bolster economic damages beyond medical bills alone. Document how an injured person cannot miss work without financial losses.
• Refine intake scripts. Quickly identify policy limits, UM/UIM coverage, and catastrophic injuries so high-value leads are prioritized. Do not waste resources on files that will not clear your minimum net-fee threshold under the new legal principles.
• Explore a partnership with Walker Advertising. Diversify your lead sources, increase volume in higher-value segments, and build a more resilient practice before SB 623 reshapes recover damages dynamics across California.
