Bringing a Medical Malpractice Case Against Kaiser Permanente in Santa Ana

If you or a family member were harmed by care at Kaiser Permanente, your claim will almost certainly not be heard by a jury. It will be decided in private, binding arbitration run under rules written for Kaiser members, administered by an office Kaiser funds, and decided by a neutral arbitrator whose fee Kaiser usually pays.

That is not a reason to give up. Kaiser cases settle every day, and arbitration has real advantages for patients: it is faster than court, cheaper, and in some situations it can be fast-tracked for patients who are very ill or elderly. But it is a closed system with its own rules, its own deadlines and its own culture. Kaiser is in every one of those arbitrations. Most of the patients on the other side are there once.

Ikuta Hemesath Leonard LLP represents patients and families against Kaiser across California. We have handled dozens of Kaiser matters, from birth injuries and missed cancers to surgical errors and wrongful deaths, in arbitration and in Superior Court. This page explains how the system actually works: who Kaiser is, how arbitration proceeds step by step, its upsides and downsides, and why the firm you choose matters more in a Kaiser case than almost anywhere else.

Who “Kaiser” Actually Is

“Kaiser Permanente” is a brand, not a single company. In California it is a partnership of three kinds of organizations, bound together by exclusive contracts. Knowing which entity did what is the first step in any Kaiser case, because each one has different duties and different defenses.

Kaiser Foundation Health Plan, Inc. — the insurer

The Health Plan is the nonprofit HMO you or your employer pays premiums to. It enrolls members, decides what is covered and holds the membership agreement (the “Evidence of Coverage”) that contains the arbitration clause. It does not employ the doctors. Under California’s Knox-Keene Act, a health plan is generally not vicariously liable for its providers’ malpractice (Health & Safety Code § 1371.25), so Kaiser regularly asks to have the Health Plan dismissed. The Health Plan still matters: it is the party that enforces arbitration, and it is responsible for its own decisions on access, authorization and coverage.

Kaiser Foundation Hospitals — the hospitals and their staff

Kaiser Foundation Hospitals is a separate nonprofit that owns and runs the Kaiser hospitals and many medical office buildings. It employs most of the nurses, pharmacists, technicians, advice-line staff and other non-physician personnel. When a labor nurse misses a deteriorating fetal heart tracing, an aspiration-precaution order is not carried out, or a medication is given wrong, the claim usually runs against Kaiser Foundation Hospitals.

The Permanente Medical Groups — the doctors

Kaiser physicians are not employed by the Health Plan or the hospitals. They belong to separate physician-owned medical groups that contract exclusively with Kaiser:

The Permanente Medical Group (TPMG) — Northern California, including the Bay Area, Sacramento, the Central Valley and Fresno.
Southern California Permanente Medical Group (SCPMG) — Southern California, from Kern County to San Diego.

The Health Plan pays the medical group a fixed monthly amount for each member (capitation), and the group pays its physicians. Kaiser’s own disclosures describe physician pay as a salary supplemented by incentives tied to measures such as quality and access. The groups are the defendants for physician decisions: the missed diagnosis, the surgical error, the decision not to biopsy.

Northern vs. Southern California

The two regions run as separate systems with different medical groups, different leadership, different internal guidelines and different legal departments. A demand for arbitration is served on the Health Plan’s Legal Department in Oakland for Northern California cases and in Pasadena for Southern California cases. Kaiser also uses different outside defense firms in each region. In California alone Kaiser serves roughly 9.7 million members at 37 hospitals with about 18,800 physicians (Kaiser Permanente Fast Facts).

Why the structure matters to your case

Kaiser is an integrated system: one organization insures you, schedules you, runs the hospital, employs the nurses and contracts with the doctors. That integration is the source of many Kaiser injuries. Gaps between departments, appointment backlogs, unanswered messages and cost-driven protocols are system decisions, not just one doctor’s mistake. A Kaiser claim should name every responsible entity (typically the Health Plan, Kaiser Foundation Hospitals and TPMG or SCPMG), and often the individual providers, so that no part of the system can point at another one that is not in the case.

Why Are Kaiser Members in Arbitration?

Kaiser has required its California members to arbitrate disputes since 1971. The requirement is in the membership agreement you, your employer or your union signed when you enrolled. California law requires health plans to disclose the arbitration clause prominently and to state plainly that members are giving up a jury trial (Health & Safety Code § 1363.1). When those requirements are met, courts enforce the clause.

It usually binds your family too

The agreement does not just bind the member who signed it. Under Ruiz v. Podolsky (2010) 50 Cal.4th 838, a valid medical-malpractice arbitration agreement generally binds the patient’s heirs in a later wrongful-death claim, including adult children who never signed anything. Spouses’ loss-of-consortium claims and claims by children injured at birth are usually swept in as well. Medicare Advantage (Senior Advantage) members sign their own arbitration agreement on enrollment.

Filing in court anyway

Arbitration is not automatic. Kaiser has to prove a valid agreement, and some cases are properly filed in Superior Court, either because the agreement does not apply, because Kaiser waived it, or because other defendants are involved. Kaiser routinely petitions to compel those cases into arbitration. California also penalizes a drafting party that pays arbitration fees late (Code of Civil Procedure §§ 1281.97–1281.98); after Hohenshelt v. Superior Court (2025), the late payment must be willful, grossly negligent or fraudulent. We have both defended against Kaiser’s petitions and used these statutes to return a Kaiser case to court. Whether to start in court or in arbitration is a strategic choice that should be made deliberately, not by default.

The Office of the Independent Administrator (OIA)

Kaiser arbitrations are administered by the Office of the Independent Administrator. The OIA was created in 1999 after the California Supreme Court’s decision in Engalla v. Permanente Medical Group (1997) 15 Cal.4th 951 exposed how Kaiser’s old, self-run system delayed claims for years. Before the OIA, selecting an arbitrator took an average of 674 days. In 2025 it took 52. The OIA keeps the docket, sends the lists of possible arbitrators, enforces deadlines and publishes annual statistics. It does not decide cases and cannot give legal advice.

Who pays for it

Kaiser does. The OIA is funded through a trust Kaiser established and an oversight board controls, plus the $150 filing fee claimants pay. The neutral arbitrator’s fees are also normally paid by Kaiser: under OIA Rule 15, if the claimant signs a “Waiver of Objection to Payment of Fees” and the case has a single neutral, Kaiser pays the whole fee. In 2025 Kaiser paid the neutral’s fees in 95% of closed cases. Neutrals bill an average of $853 an hour, and the average fee in a case that goes to hearing is more than $71,000 (OIA 2025 Annual Report).

For a patient, that arrangement is a real benefit: you do not have to front tens of thousands of dollars for a private judge. But it also means the company on the other side of your case is the one paying the person deciding it, and is the only party that will be back in front of that person again and again. That is the central fact of Kaiser arbitration, and we return to it below.

How a Kaiser Arbitration Works, Step by Step

A Kaiser arbitration must be closed within 18 months of the OIA receiving the demand (OIA Rule 24), and in 2025 the average case closed in about 13 months. Here is what happens in between. Rule numbers refer to the OIA Rules as amended February 14, 2025.

1. Investigation and notice before filing

Before anything is filed, we obtain the complete Kaiser chart, including the electronic audit trail, imaging, fetal monitoring strips, patient-portal messages and advice-line call records, and have it reviewed by independent physicians in the right specialty. California requires a 90-day notice of intent before a malpractice claim is filed (Code of Civil Procedure § 364), and serving it near the deadline can extend the statute of limitations. Kaiser also must provide requested medical records within 30 days once an arbitration is pending (Rule 27(c)).

2. The demand for arbitration

The case begins with a written Demand for Arbitration served on the Health Plan’s Legal Department (Oakland for Northern California, Pasadena for Southern California) (Rule 8). It identifies the claimants and respondents, the facts, the claims and the damages. Kaiser must forward it to the OIA within 10 days (Rule 11). The claimant pays a one-time $150 filing fee, which is waived for lower-income claimants and can be waived for hardship (Rules 12–13); if it is not paid or waived within 75 days, the demand is treated as abandoned.

3. Choosing the neutral arbitrator: the strike-and-rank process

This is the most important decision in the case, and it happens in the first few weeks.

The list. Within 3 business days after the fee is paid or waived, the OIA sends both sides the same list of 12 possible neutrals, drawn at random from its regional panel (Rule 16). The panel has about 195 neutrals, most of them retired judges.
Agree if you can. The parties may jointly select anyone on the list, or even someone not on it who agrees to serve (Rule 17). About 22% of neutrals are chosen this way.
Strike. Otherwise, each side may strike up to 4 names for any reason or no reason (Rule 18(a)).
Rank. Each side ranks every remaining name, 1 being its first choice. No blanks are allowed (Rule 18(b)).
Deadline. Responses are due 20 days after the list is sent (Rule 16(c)). A party that misses the deadline is treated as finding every name equally acceptable (Rule 18(c)), which effectively hands the choice to the other side.
Selection. The OIA adds the two sides’ rankings and invites the person with the best combined score whom neither side struck (Rule 18(e)).
Disclosure and challenge. The selected neutral must disclose prior and pending cases with the parties and their lawyers, and other potential conflicts, under Code of Civil Procedure § 1281.9. A party can disqualify the neutral based on those disclosures. After two disqualifications, the OIA picks at random (Rule 18(f)).

Either side may ask once for a 90-day postponement of the selection process (Rule 21); for members, the postponement is the claimant’s to use. The strategy behind strikes and ranks is where experience counts most, and we discuss it in detail below.

4. One arbitrator or three

For claims of $200,000 or less, one neutral decides the case. For larger claims, either side may insist on a three-person panel: the neutral plus one “party arbitrator” chosen by each side (Rule 14). Party arbitrators are not required to be neutral (Rule 4); each may be predisposed toward the side that chose them and gives that side a voice in the panel’s deliberations.

The trade-off is cost. If the claimant keeps party arbitrators, the claimant pays their own party arbitrator and the neutral’s fees are split 50/50 instead of being paid by Kaiser (Rule 15). Most claimants waive party arbitrators, and in 2025 all but one of 23 hearings were decided by a single neutral. The waiver is due by the Arbitration Management Conference. In a high-value case, a panel can be worth the cost.

5. The Arbitration Management Conference

Within 60 days after the neutral is confirmed, the neutral holds a scheduling conference, often by phone or video (Rule 25). The neutral sets the hearing dates (consecutive days), motion deadlines and the date of the Mandatory Settlement Meeting, and records them on a form served on everyone. This is also where the parties raise expedited scheduling, bifurcation of liability and damages, complex-case designation and protective orders.

6. Discovery

Discovery follows the same California rules as a civil lawsuit (Rule 27): written interrogatories, document requests, depositions of the Kaiser doctors and nurses, subpoenas to outside providers, and expert witness exchange. Kaiser cases often turn on internal records that only come out in discovery: electronic audit trails, message and call logs, scheduling data, internal guidelines and staffing records. The neutral decides discovery disputes and can award sanctions for abuse (Rule 41).

7. Motions

Kaiser frequently brings a motion for summary judgment, usually arguing that the care met the standard of care or did not cause the injury. In 2025, 14% of closed cases ended on summary judgment. With a three-person panel, dispositive motions are decided by all three arbitrators (Rule 6). A properly supported expert declaration is essential.

8. The Mandatory Settlement Meeting

No later than six months after the management conference, the lawyers must meet to discuss settlement, with full authority or the clients available by phone (Rule 26). The neutral does not participate. Code of Civil Procedure § 998 offers apply in Kaiser arbitration, and many cases are resolved here or through private mediation. In 2025, 57% of closed Kaiser arbitrations settled.

9. The hearing

The hearing works like a bench trial: opening statements, witness testimony, expert witnesses, exhibits and closing argument, usually in a conference room rather than a courtroom. Most medical-malpractice hearings last several days to two weeks. Post-hearing briefs are due no more than 15 days after the parties rest (Rule 31).

10. The award

The neutral must serve a written award within 30 days after the hearing closes, or 45 days in complex cases (Rule 37). The award states who prevailed, the relief and the reasons, with findings of fact and conclusions of law (Rule 38).

11. After the award

The award is binding. It can be confirmed as a court judgment, and it can be vacated only on narrow grounds such as fraud, arbitrator misconduct or an undisclosed conflict (Code of Civil Procedure § 1286.2). There is no appeal for legal or factual error. Both sides get one chance, which is why preparation and the choice of neutral matter so much.

Expedited Arbitration for Patients Who Are Seriously Ill or Elderly

When a patient may not live to see an ordinary 18-month schedule, Kaiser arbitration can move much faster than a lawsuit. The OIA Rules allow expedited procedures when a claimant needs an award sooner, based on (Rule 33(a)):

an illness or condition that raises substantial medical doubt the claimant will survive until the normal award date;
the need for a decision about a drug or procedure the claimant has not yet received; or
other good cause, which can include advanced age combined with serious health problems.

How it works

Request to the OIA (Rule 34). The claimant serves a written request explaining the reason and the date by which an award is needed, supported by evidence such as a physician’s declaration. Kaiser has 7 days to oppose, and the OIA decides within 5 days after that. If granted, the OIA confirms the neutral can meet the deadline, no 90-day postponement of neutral selection is allowed, and discovery can start immediately.
Request to the neutral (Rule 35). If a neutral is already appointed, a party can petition the neutral at any time.
Compressed schedule (Rule 33(c)–(d)). The neutral sets a deadline for the award and can shorten discovery response times and motion schedules to meet it. Notices are given by phone and confirmed in writing (Rule 36).

Why it matters

In California, a patient’s own pain and suffering damages can be lost if the patient dies before a judgment or award, and a wrongful-death claim compensates the family under different rules. A dying patient’s testimony is also the most powerful evidence in the case. In Superior Court, even with trial preference, a seriously ill plaintiff may wait many months for a trial date. In Kaiser arbitration, a properly supported expedited request can produce a hearing and an award in a fraction of the normal time. Expedited cases are rare, which is exactly why the request has to be made early, supported with the right medical evidence and paired with a realistic discovery plan.

The Upsides of Kaiser Arbitration

Arbitration is often described only as a disadvantage for patients. In our experience, it has real benefits that a skilled firm can use.

Speed. Kaiser arbitrations must close within 18 months, and the average case closed in about 13.5 months in 2025. A medical-malpractice lawsuit in Superior Court commonly takes three years or more to reach trial. For an injured child who needs care now, an elderly patient or a family that cannot wait, that difference is enormous.
Kaiser usually pays the arbitrator. In a single-neutral case, the claimant pays only the $150 filing fee (often waived), and Kaiser pays the neutral’s fees, which average more than $71,000 in a case that goes to hearing.
A decision-maker who understands medicine. Most neutrals are retired judges or experienced trial lawyers who have heard many malpractice cases. They can follow a fetal heart tracing or a radiology dispute in a way a lay jury may not, and they are less swayed by the “doctors are heroes” instinct that makes medical-malpractice jury trials so difficult for patients.
Fast-tracking for the dying and the elderly. The expedited procedures described above have no real equivalent in civil court.
A firm deadline drives settlement. Kaiser cannot delay indefinitely. A fixed hearing date and a mandatory settlement meeting give both sides a reason to evaluate the case early, and most Kaiser arbitrations settle.
Flexible scheduling. Hearing days are consecutive and set months in advance. Liability and damages can be heard separately, which lets a family avoid an expensive damages presentation unless liability is found first.
Privacy. The hearing and award are confidential. For families dealing with a birth injury, a death or a sensitive diagnosis, keeping medical details out of a public courtroom can matter.
Finality runs both ways. Kaiser cannot appeal a claimant’s award on the merits, and a patient who wins does not wait years for an appeal to be decided.

The Downsides of Kaiser Arbitration

The benefits are real, but so are the risks. Patients should understand them before they decide who will represent them.

No jury. You give up the right to have your community decide your case. One person, usually a retired judge, decides liability and damages.
Kaiser funds the system and usually pays the judge. The OIA is funded through a Kaiser-established trust, and Kaiser paid the neutral’s fees in 95% of closed cases in 2025. Every neutral knows Kaiser will be a party in every future Kaiser arbitration they are selected for.
Kaiser is the ultimate repeat player. Kaiser and its regular defense firms appear before the same neutrals year after year and know how each one rules. A patient who comes to the process once, with a lawyer who rarely handles Kaiser cases, does not have that information.
Hearings are hard to win. Only about 4% of closed cases go all the way to an award, and in 2025 claimants prevailed in 6 of 23 hearings. Those numbers include many claimants without lawyers, but they still show that weak or under-prepared cases rarely succeed.
Awards can be conservative. Critics have long argued that neutrals who issue large awards against Kaiser risk being struck in future cases, which can push awards toward the middle. The OIA’s own data does not show neutrals being excluded after large awards, but the concern is widespread in the plaintiffs’ bar, and it shapes how we choose and rank neutrals.
Almost no appeal. An award can be vacated only for fraud, misconduct or an undisclosed conflict. An arbitrator who gets the law or the facts wrong is usually not correctable.
Your family is bound too. Heirs bringing a wrongful-death claim are generally held to the patient’s arbitration agreement, even if they never signed it.
Secrecy protects Kaiser as well. Confidential awards mean patterns of system failure rarely become public, and there is no published verdict to pressure the next settlement.
Party arbitrators cost money. Keeping a three-person panel in a large case means paying your own party arbitrator and half of the neutral’s fees.
The rules punish mistakes. Missing the 20-day strike-and-rank deadline hands the choice of neutral to Kaiser. Missing the filing-fee deadline abandons the claim. In 2025, 38% of Kaiser claimants had no lawyer, an all-time high, and unrepresented claimants rated their neutrals 1 out of 5 while represented parties rated them above 4.

Why Your Firm Must Be a Repeat Player Too

In a Kaiser arbitration, the most important question is not just whether your lawyer is competent. It is whether your lawyer will be back. The firm you hire should handle Kaiser arbitrations constantly, because that is the only way to balance an economic incentive that otherwise points in one direction.

The incentive the system creates

Neutral arbitrators are paid by the case, at rates averaging over $850 an hour. A neutral is chosen only when both sides’ strike-and-rank lists leave that person at the top. Kaiser submits a list in every single case. A neutral whom Kaiser’s lawyers come to view as unfavorable can be struck again and again, across hundreds of cases a year, and quietly stop being selected. A patient who will never be in a Kaiser arbitration again has no comparable influence over that neutral’s future.

That does not mean neutrals are dishonest. Most work hard to be fair. But every neutral understands that one party will be ranking them in every future case, and the incentive is to remain acceptable to that party. Academic research on Kaiser’s OIA data has found that the experience of the claimant’s lawyers in arbitration affects outcomes more than almost any other variable (Chandrasekher & Horton, Arbitration Nation , 107 Cal. L. Rev. (2019)).

How a repeat-player firm evens the field

Our firm has handled dozens and dozens of matters against Kaiser, and we have many open at any given time. That changes the dynamic in several ways:

We rank neutrals in case after case. A neutral who treats our clients unfairly is a neutral we will not select again, in any of our future Kaiser cases. A neutral who is fair to patients is one we will keep ranking highly. Our firm’s rankings matter to a neutral’s caseload in the same way Kaiser’s do.
We keep our own records on every neutral. We maintain an internal ranking of the OIA panel built from our own hearings, rulings, settlement conferences and disclosures, and we update it every time we receive a new list. We know which neutrals grant summary judgment readily, which allow full discovery into Kaiser’s systems, which understand birth-injury and diagnostic-delay cases, and which have spent their careers defending doctors.
We read every disclosure. Neutrals must disclose their prior and pending cases with Kaiser and with the lawyers involved. We know what those numbers mean, and we use disqualification when the disclosures warrant it. Claimants disqualified neutrals 39 times in 2025.
We know Kaiser’s defense lawyers. Kaiser uses a relatively small group of defense firms in each region. We know how they prepare, which experts they use, when they make serious settlement offers and when they are bluffing.
We know how Kaiser works internally. We know where Kaiser’s records live, how its referral and messaging systems work, which internal guidelines govern a given decision, and what Kaiser’s electronic audit trail can show about who saw a result and when.

Kaiser cases are not a sideline

Many personal-injury firms take an occasional Kaiser case. A firm that handles one Kaiser arbitration every few years walks into that system as a stranger, with no information about the neutrals on its list and no future business to influence how it is treated. A medical-malpractice firm that is in the system every month walks in with both. In arbitration, that is not a luxury. It is the counterweight to the repeat-player advantage Kaiser already has.

The Kaiser Cases We Handle

Our Kaiser cases span almost every department, in both Northern and Southern California, in OIA arbitration and in Superior Court. The examples below are drawn from cases we have resolved. Identifying details and results are omitted, and every case depends on its own facts.

Birth injuries and obstetric care

Hypoxic-ischemic encephalopathy (HIE) and cerebral palsy after inductions in which Pitocin was continued or increased despite excessive contractions and worsening fetal heart tracings.
Late escalation from midwife to obstetrician in midwife-run labors, including a midwife away from the bedside during pushing and an obstetrician called only after the tracing became critical.
Delayed emergency C-sections, including delays from lost IV access and anesthesia availability.
Missed cooling window after a baby was born at a facility without therapeutic-hypothermia capability.
Stillbirth from undiagnosed preeclampsia in a high-risk pregnancy.
Wrongful birth after a genetic carrier screening error.

Delayed and missed cancer diagnosis

Lung cancer in a nonsmoker whose persistent cough was treated by several specialties for years without a chest CT.
Sarcoma and brain masses visible on MRI but not reported by the radiologist.
Prostate cancer in men with a strong family history who were never offered PSA screening at years of annual physicals.
Melanoma and skin cancer treated as a cyst or chronic wound without a biopsy.

Other delayed diagnoses

Kidney disease with years of declining kidney function blamed on dehydration and no timely nephrology referral.
Spinal epidural abscess and cauda equina syndrome sent home from the emergency department or misdiagnosed, leading to paralysis or permanent nerve damage.
Blood disorders, sepsis, pericarditis and gastrointestinal bleeding where abnormal labs and vital signs were not acted on.
Fractures and vascular injuries missed at telephone advice, urgent care and follow-up visits.

Surgical and post-operative care

Missed nerve and artery injuries after routine hand surgery.
Fatal pulmonary embolism after orthopedic surgery when a high-risk patient received only the standard aspirin protocol.
Amputations after post-operative infections and misdiagnosed arterial wounds.
Positioning injuries during long operations.

Hospital, emergency and nursing care

Aspiration deaths when ordered feeding precautions were not followed.
Kidney injury from contrast dye in a high-risk elderly patient.
Falls and brain bleeds in patients kept in urgent care who needed a hospital.
Unsafe discharges of patients with abnormal vital signs or labs.

The Administrative and System Failures Behind Kaiser Injuries

In many of our Kaiser cases, the clinical mistake is only half the story. Kaiser is a closed, integrated system, and injuries often happen in the spaces between its departments. These system failures appear again and again in our cases:

Patient messages that go nowhere. Urgent portal messages, sometimes with photos of a worsening wound, sat unanswered for weeks because a physician was away and no one covered the inbox.
Appointments that cannot be had. A high-risk pregnant patient had prenatal visits cancelled repeatedly during a staffing shortage and was told the next opening was weeks away.
Advice lines and urgent care that do not escalate. Callers and walk-in patients with red-flag symptoms were reassured and sent home rather than routed to a physician or an emergency department.
Abnormal results that are not acted on. Worsening lab trends, an abnormal post-operative X-ray and incidental findings on MRI were never communicated to the patient or the treating doctor.
Specialty silos. A patient was referred among several departments, each treating its own piece, and no one owned the diagnosis or asked why treatment kept failing.
One-size-fits-all protocols. Standard pathways, such as aspirin-only clot prevention or routine contrast imaging, were applied to patients whose risks called for something different.
Telephone check-ins instead of visits for patients whose condition was deteriorating.
Transfers between facilities that delayed surgery or treatment, and hospitals without the capability the patient needed.
Care plans not carried out at the bedside, confirmed in one case by a state Department of Public Health investigation.
Charting that does not match reality, such as fetal monitoring described as reassuring when the strip showed distress.
Screening left to paperwork. Kaiser has defended missed cancer screening by pointing to after-visit summaries that said screening was “available.”

These failures matter legally because they are institutional. They can establish negligence by Kaiser Foundation Hospitals and the medical group, not just an individual doctor, and they are usually proven through records Kaiser does not volunteer: message logs, scheduling data, call records, audit trails and internal policies. Knowing what to ask for, and where it lives in Kaiser’s systems, is a large part of what we do.

Damages, MICRA and Deadlines in Kaiser Cases

Kaiser arbitration applies the same California malpractice law as a courtroom, including the Medical Injury Compensation Reform Act (MICRA).

What can be recovered

Economic damages, with no cap: past and future medical care, attendant and nursing care, lost earnings and earning capacity, and household services. In a catastrophic injury case, a life-care plan and an economist usually drive the value of the case.
Non-economic damages for pain, suffering and loss of enjoyment of life, which are capped. Under the 2023 MICRA reform (AB 35), the cap for 2026 claims is $470,000 for injury cases and $650,000 for wrongful-death cases, rising each January 1 until it reaches $750,000 and $1,000,000 in 2033 (Civil Code § 3333.2).
Separate caps can stack. The reform created separate caps for health-care providers, for health-care institutions, and for unaffiliated providers or institutions. In a Kaiser case, the medical group and the hospital entity may fall under different caps, and naming the right Kaiser entities can make a substantial difference.
Wrongful-death damages for the family’s loss of love, companionship, support and services, subject to the death cap.

Kaiser often argues that future medical care will simply be covered by insurance, to shrink the economic damages. Responding to that argument with the right experts is part of building a Kaiser case.

Attorney’s fees

California limits contingency fees in medical-malpractice cases to 25% of a recovery obtained before a lawsuit or demand for arbitration is filed and 33% after filing (Business & Professions Code § 6146). We work on a contingency basis: no fee unless there is a recovery.

Deadlines

Statute of limitations. Generally one year from when you discovered, or should have discovered, the injury and its cause, and no more than three years from the injury (Code of Civil Procedure § 340.5). Different rules apply to minors.
90-day notice. A notice of intent must be served at least 90 days before the claim is filed (Code of Civil Procedure § 364).
Do not wait for Kaiser. Kaiser’s internal grievance process, its patient-relations department and complaints to regulators do not stop the statute of limitations. Talk to a lawyer while records and memories are fresh.

Frequently Asked Questions

Can I sue Kaiser in court instead?

Usually not. If you are a Kaiser member, your membership agreement almost always requires binding arbitration. There are exceptions, and some claims against non-Kaiser providers can proceed in court, so have a lawyer review the agreement before assuming either way.

Is the OIA part of Kaiser?

No. The OIA is a separate administrator that runs the process and enforces the rules. But Kaiser funds it, and Kaiser usually pays the neutral arbitrator.

Do I have to pay the arbitrator?

In most cases, no. If you agree to a single neutral and sign the fee waiver form, Kaiser pays the neutral’s fees. You pay a $150 filing fee, which can be waived.

How long will my case take?

Most Kaiser arbitrations close within 18 months, and the average in 2025 was about 13.5 months. Complex cases can be extended to 30 months. Seriously ill claimants can ask for an expedited schedule.

Will there be a public trial?

No. The hearing is private and the award is confidential.

Can I appeal if I lose?

Only on very narrow grounds such as fraud or an undisclosed conflict. That is why choosing the neutral and preparing the case thoroughly matter so much.

My family member died at Kaiser. Is my wrongful-death claim in arbitration too?

In most cases, yes, even if you never signed the agreement yourself.

Can I handle a Kaiser arbitration without a lawyer?

You can, and a record 38% of Kaiser claimants did in 2025. But missing a strike-and-rank deadline, a fee deadline or an expert disclosure can lose the case, and you will be facing a company and defense firms that do this every day.
