California Medical Malpractice Laws (2026): Statute of Limitations, Damages Cap & Merit Rules

By John Mahoney · May 29, 2026 · 10 min read

California is the largest medical malpractice market in the country and the only one to have meaningfully reformed its MICRA non-economic damages cap in nearly five decades. The 2022 enactment of AB 35 (effective January 1, 2023) replaced the static $250,000 cap with an annually-escalating schedule that splits injury and wrongful-death cases — a structural change that has reshaped case valuation across the state.

For plaintiff attorneys, California's combination of a short 1-year discovery limitations period, a strict 3-year occurrence cap, the 90-day notice-of-intent requirement under Code of Civil Procedure 364, and the rolling MICRA cap escalation makes early case organization more important than in almost any other jurisdiction. This page summarizes the legal landscape and how MedLegal AI accelerates the work.

California Medical Malpractice Legal Landscape

Statute of limitations — CCP 340.5

California Code of Civil Procedure 340.5 sets the statute of limitations as the earlier of:

• 1 year from the date the plaintiff discovered (or through reasonable diligence should have discovered) the injury, or
• 3 years from the date of injury — an absolute outer limit regardless of discovery.

Tolling applies for fraud, intentional concealment, and the presence of a foreign body that has no therapeutic or diagnostic purpose. For minors, the limitations period is tolled until the minor turns 6 for children injured under age 6; older minors must file within 3 years of injury. See our 50-state SOL guide for cross-reference.

90-day notice of intent — CCP 364

California requires the plaintiff to serve a written notice of intent to commence action at least 90 days before filing suit under CCP 364. The notice must identify the legal basis for the claim, the type of loss sustained, and the nature of the injuries. Failure to give proper notice is not a jurisdictional defect but can result in discipline and abatement. If the notice is served within 90 days of the SOL running, the limitations period is extended by 90 days.

MICRA non-economic damages cap — AB 35 schedule

For nearly five decades MICRA capped non-economic damages at a flat $250,000. AB 35, signed by Governor Newsom in 2022 and effective January 1, 2023, replaced the flat cap with a tiered, escalating schedule:

• Non-death (injury) cases: cap began at $350,000 in 2023 and escalates by $40,000 per year until it reaches $750,000 in 2033, then 2% annual inflation indexing thereafter.
• Wrongful death cases: cap began at $500,000 in 2023 and escalates by $50,000 per year until it reaches $1,000,000 in 2033, then 2% annual indexing.
• Multiple caps: AB 35 allows up to three separate caps — one each for healthcare provider, healthcare institution, and unaffiliated provider — substantially raising the practical ceiling on non-economic recovery.

The MICRA cap applies only to non-economic damages (pain and suffering, loss of consortium). Economic damages (medical, lost wages, lost earning capacity, life-care costs) remain uncapped.

MICRA contingency-fee schedule and periodic payments

Business & Professions Code Section 6146 imposes a sliding-scale contingency fee schedule on MICRA cases. CCP 667.7 permits periodic payments for future damages above $250,000 at any party's election.

Certificate-of-merit / expert affidavit

California does not require a pre-suit certificate of merit or expert affidavit, distinguishing it from Texas, Florida, Illinois, and several other states. Plaintiff lawyers nevertheless typically engage a medical expert before filing because of the Daubert / Sargon standard and the practical reality of motion practice in California.

Common Med-Mal Case Types in California

• Emergency department misdiagnosis — stroke / tPA window, missed sepsis, missed PE, headache cocktail without imaging. Same fact patterns as Florida, with MICRA cap valuation differences.
• Birth injury — HIE, shoulder dystocia, delayed cesarean. Birth injury cases are particularly valuable post-AB 35 because lifetime economic damages remain uncapped and the wrongful-death cap (where applicable) rises to $1M by 2033.
• Surgical errors — retained foreign objects, wrong-site surgery, robotic surgery, anesthesia complications. The CCP 340.5 foreign-body tolling exception applies.
• Failure to diagnose cancer — breast, colorectal, lung. California recognizes loss-of-chance damages with developed case law.
• Nursing home elder abuse — California's Elder Abuse and Dependent Adult Civil Protection Act (Welfare & Institutions Code 15600 et seq.) provides enhanced remedies including attorney's fees and is not subject to MICRA's non-economic cap when the conduct is reckless or willful. Falls, pressure injuries, neglect.
• Medication errors — anticoagulant mismanagement, insulin overdose, opioid prescribing.
• Anesthesia complications — failure to monitor, intubation injuries, spinal hematoma after neuraxial block.

How MedLegal AI Accelerates California Med-Mal Work

Medical chronology — 14 hours to 22 minutes

The 1-year discovery deadline under CCP 340.5 leaves little room for slow record review. Our Timeline Builder ingests the record set, extracts every provider encounter, diagnosis, medication, and key value, and produces a structured chronological timeline in roughly 22 minutes — the same work product that historically took 14 hours of LNC time. Output is editable and source-cited back to the original page.

Daubert / Sargon preparation — 12 hours to 30 minutes

California applies the Sargon Enterprises v. USC standard for expert testimony — a state-court analogue of Daubert that requires the trial court to act as gatekeeper. Our Daubert Challenge tool drafts a first-pass Sargon / FRE 702 challenge skeleton from a deposition transcript or expert report. Every output is processed by our hallucination scrubber — any case citation outside the foundational Daubert / Kumho / Joiner / Frye line is flagged [VERIFY CITE] for attorney review.

Standard-of-care analysis

The Case Analysis tool reads the medical record and intake narrative, identifies the standard-of-care issues at each decision point, and proposes a list of likely breaches and supporting evidence. This eliminates 4 to 8 hours of associate review time before the expert is engaged.

Causation chain builder for California

California applies the substantial factor causation standard (CACI 430) in negligence cases. Our Causation Chain Builder structures the breach → mechanism → harm → damages sequence in a format that maps directly onto CACI and survives a Sargon challenge.

Recent California Medical Malpractice Verdicts

The post-AB 35 environment has revalued California medical malpractice claims, particularly elder abuse and birth injury cases where the MICRA cap was historically a major case-value ceiling. The following is a representative recent verdict from our verdict aggregator; counsel should verify each through the source link before citing.

Note: California verdict reporting is fragmented. For comprehensive current verdict intelligence we recommend the Consumer Attorneys of California (CAOC) verdict database and the Trials Digest reporter.

Practical Workflow Under CCP 340.5 and CCP 364

A practical California workflow that we see succeed in plaintiff firms looks like this:

• Days 1–7 — Intake and SOL calculation. The 1-year discovery clock under CCP 340.5 is unforgiving. Document the date the client discovered (or should have discovered) the injury and run the 1-year and 3-year scenarios in parallel. Identify each potential defendant including any sovereign-immunity exposures.
• Days 7–30 — Records ingestion and chronology. Upload records to MedLegal AI as they arrive. Get a structured chronology in minutes. Identify standard-of-care issues with Case Analysis. Confirm whether the Elder Abuse Act (Welfare & Institutions Code 15600) provides a parallel non-MICRA path.
• Days 30–60 — Expert engagement. California does not require a pre-suit certificate of merit, but engaging a qualified expert before filing is best practice. Provide the chronology, case-analysis summary, and causation chain. Confirm same-specialty qualification for any Sargon challenge.
• At least 90 days before filing — Serve CCP 364 notice. The notice must identify the legal basis for the claim and the nature of the injuries. If notice is served within 90 days of the SOL, the limitations period is extended by 90 days.
• Days 90–180 — Complaint, structuring, and AB 35 valuation. File the complaint after the CCP 364 window. Identify the year-specific MICRA cap that will apply at trial under the AB 35 schedule. Negotiate periodic-payment structures for any future-damage component above $250,000 under CCP 667.7.

The AB 35 escalation makes case valuation a moving target — settlements in late 2026 may be valued against a higher cap than settlements in early 2026.

Get Started

If you are evaluating a California medical malpractice claim, the 1-year discovery clock under CCP 340.5 plus the 90-day CCP 364 notice requirement reward firms that can organize the medical record fast. The AB 35 cap-escalation schedule also rewards careful case-valuation work in years where the cap steps up.
