    Erik, I'm incredibly grateful that [husband stroke victim] continues to improve - long after it was thought to be possible.
    “He couldn't have managed independence to this extent, his current level of physical activity, or the complexity of his recent social interactions 6 months ago. None of it would have happened without ongoing therapeutic support - which has only been possible with the financial settlement.”

    - Margaret C.
    Erik Peterson handled my case with care and compassion.
    “His knowledge and attention to detail was stellar, making me feel secure during a difficult case. Unlike most people in life, he was always upfront with me and kept me updated every step of the way, which is truly not what I was expecting from a lawyer. Although it was determined my case could take several years, especially during a pandemic, due to his dedication it was over in only 2yrs and made the process as easy for me as possible. I would absolutely recommend this firm and use him again if I ever need to, although I hope I don't.”
    - Kristy N.
    This whole experience can be overwhelming but Erik kept me in the loop on everything.
    “My husband passed due to medical malpractice and I didn't know what to do or who to call. All I knew was I needed to get him justice. I researched and found Erik Peterson on google and reviewed various reviews on various sites. He was very patient and fought for me and my late husband. Erik told me what to expect ahead of time so I could prepare myself mentally. All in all, I HIGHLY recommend them to anyone who may need legal assistance in personal injury, medical malpractice and wrongful death. They are excellent and I can't say enough good things about them.”
    - Kiki A.

Understanding Kaiser Medical Malpractice in California

Kaiser Permanente’s integrated model provides care to millions of Californians, including thousands of patients in the Los Angeles area. But when serious errors occur within Kaiser’s system, injured patients and families face a legal process that’s very different from a typical medical malpractice lawsuit.

Kaiser cases follow a mandatory private arbitration process, not the civil court system. Instead of a jury trial, claims are heard by a neutral arbitrator under strict procedural rules. Some key differences include:

  • No jury · Cases are decided by an arbitrator or arbitration panel, not a jury of peers.
  • Tight timelines · Arbitration has rigid filing and notice deadlines that must be met to preserve your claim.
  • Different evidentiary rules · Hearings resemble trials but follow distinct procedures set by Kaiser’s system.
  • Powerful institutional defense · Kaiser brings significant legal and financial resources to every case.

While arbitration can sometimes move faster than civil court, it’s designed for efficiency, not public accountability. To prevail, you need deep familiarity with Kaiser’s arbitration system and the medical expertise to build a compelling case.

Common Forms of Medical Negligence

Kaiser malpractice claims can arise from nearly every area of medicine. Some of the most common forms of negligence we see in Los Angeles Kaiser cases include:

  • Failure to Diagnose or Delayed Diagnosis · Missed or delayed detection of serious conditions such as infections, strokes, heart disease, or cancer.
  • Birth Injuries · Negligence during pregnancy, labor, or delivery leading to lifelong disabilities, often due to failures to monitor fetal distress or treat maternal infections.
  • Surgical Errors · Mistakes made before, during, or after surgery, including wrong-site procedures, anesthesia errors, or failure to manage complications.
  • Emergency Room Negligence · Failure to properly triage, monitor, or stabilize patients presenting with urgent symptoms.
  • Medication and Anesthesia Errors · Dosing mistakes, contraindicated drug administration, or anesthesia complications that result in catastrophic injury.
  • Systemic Failures · Breakdowns in communication, referral delays, understaffing, or rigid protocols that override clinical judgment—issues often specific to large, integrated systems like Kaiser.

How the Kaiser Malpractice Legal Process Works

Filing a malpractice claim against Kaiser involves several critical steps, each requiring precision and medical-legal expertise:

  1. Case Evaluation & Investigation. Our team conducts a thorough review of medical records, consults leading medical experts, and determines whether the care provided fell below accepted standards.
  2. Pre-Arbitration Notice. California law requires claimants to provide Kaiser with written notice at least 90 days before filing for arbitration. This step starts the clock on important deadlines.
  3. Filing the Arbitration Demand. Instead of filing in court, claims are filed with Kaiser’s arbitration system. A neutral arbitrator (or panel) is selected, and the case proceeds similarly to litigation, with discovery, depositions, and expert testimony.
  4. Arbitration Hearing. The hearing functions much like a trial, but without a jury. Expert testimony, medical records, and witness evidence are presented to the arbitrator, who ultimately issues a binding decision.
  5. Resolution. Many cases resolve through negotiated settlements during the arbitration process. When necessary, our firm is fully prepared to take the case through the hearing and beyond.

Because Kaiser arbitration is governed by strict timelines and procedural rules, starting early is critical. Missing a deadline or mishandling procedural steps can jeopardize your right to compensation.

Do You Have a Case?

Not every poor medical outcome is malpractice. A valid Kaiser malpractice claim typically requires proof that:

  1. A Kaiser provider owed you a duty of care;
  2. That duty was breached through negligent care;
  3. The negligence caused significant injury or harm; and
  4. You suffered measurable damages, such as medical expenses, lost income, or permanent disability.

Determining whether malpractice occurred involves expert medical review and careful legal analysis. If you suspect negligence, speaking with an experienced medical malpractice lawyer as soon as possible can help protect your rights.

Why Experienced Representation Matters

Kaiser’s size, resources, and private arbitration system make these cases uniquely challenging. Success depends on:

  • Medical knowledge to identify negligence others might miss
  • Litigation and arbitration experience to navigate procedural hurdles
  • Access to top medical experts who can provide credible testimony
  • A track record of results in high-stakes malpractice cases

Our firm has built that foundation over decades. We know how Kaiser approaches these claims and how to hold them accountable.
