California Medical Malpractice Laws

California medical malpractice claims have a shorter statute of limitations than general personal injury (1 year from discovery or 3 years from injury). The state caps non-economic damages under MICRA, with caps that increase annually through 2033 following the passage of AB 35 in 2022. California requires 90 days' pre-suit notice to each defendant before filing a medical malpractice lawsuit.

Statute of Limitations

1 year from discovery or 3 years from injuryCal. Civ. Proc. Code § 340.5

Medical malpractice claims must be filed within 1 year after the plaintiff discovers (or should have discovered) the injury, but no more than 3 years after the date of the negligent act — whichever comes first.

Exceptions

Foreign Objects1 year from discoveryCal. Civ. Proc. Code § 340.5

If a foreign object was left in the body during surgery, the 1-year discovery rule applies without the 3-year outer limit.

Fraud or Concealment1 year from discoveryCal. Civ. Proc. Code § 340.5

If the healthcare provider fraudulently concealed the wrongful act, the 3-year outer limit does not apply. The 1-year period begins when the patient discovers the concealment.

Minors (under age 6)Before the child's 8th birthdayCal. Civ. Proc. Code § 340.5

For children under 6 at the time of malpractice, the deadline is extended to before the child's 8th birthday or within 3 years of the act, whichever provides a longer period.

Fault & Liability Rules

The same pure comparative fault rules apply as in general personal injury. If a patient's own negligence contributed to the injury, the award is reduced proportionally, but the patient can still recover.

Damage Caps

Non-Economic Damages (MICRA): $350,000–$1,000,000 (increasing annually through 2033)Cal. Civ. Code § 3333.2 (as amended by AB 35)

MICRA caps non-economic damages (pain and suffering) in medical malpractice cases. Following AB 35 (effective 2023), the cap starts at $350,000 for injury cases and $500,000 for wrongful death, increasing by $40,000 and $50,000 respectively each year until 2033.

Compensatory (Economic) Damages: No cap

There is no cap on economic damages (medical bills, lost wages, future care costs) in medical malpractice cases.

Filing Requirements

90-Day Notice Before FilingCal. Civ. Proc. Code § 364

The plaintiff must give 90 days' written notice to each defendant before filing a medical malpractice lawsuit. The statute of limitations is tolled during this 90-day period.

Key California Statutes

MICRA (Medical Injury Compensation Reform Act)Cal. Civ. Code § 3333.2

Originally passed in 1975, MICRA caps non-economic damages in medical malpractice cases. AB 35 (2022) updated the caps and introduced annual increases. The caps apply per-plaintiff across all defendants.

Healthcare providers must disclose material risks, alternatives, and consequences of proposed treatment. Failure to obtain informed consent can be a basis for a malpractice claim.
