In California, the medical malpractice statute of limitations refers to the time limit in which a victim of medical malpractice can file a lawsuit. Missing this deadline could result in losing the right to compensation. In this article, Wilcoxen Callaham, LLP explains the statute of limitations for medical malpractice cases and what you need to know.

What is the Medical Malpractice Statute of Limitations in California?

In California, the statute of limitations under Code of Civil Procedure section 340.5 for medical malpractice is “within one year after the plaintiff discovers, or through the use of reasonable diligence should have discovered, the injury,” or within three years of the date of the injury, whichever comes first.”

Some Exceptions to the Medical Malpractice Statute of Limitations

1. Foreign‑object cases

If a surgeon unintentionally leaves a foreign object (e.g. sponge, needle) in your body, the usual 3‑year outer limit does not apply. Instead:

  • You must file within one year of discovering the object, whenever that happens.

2. Fraudulent concealment / Intentional concealment

When a healthcare provider deliberately hid evidence of malpractice or misrepresented facts to prevent discovery:

  • The statute is tolled until the misconduct is discovered—or reasonably should have been discovered—permitting you to still sue even after 3 years.

3. Minor plaintiffs

  • If a child is under 6 when the negligence occurred, the claim must be filed within three years of the act or before the child’s 8th birthday, whichever is longer.
  • If the child is 6–17, you must file within three years of the act (no extension to age 18.)

4. Delayed discovery rule

If the injury wasn’t—and reasonably couldn’t have been—discovered right away:

  • The 1‑year filing clock begins upon discovery, or when it should have been discovered, even if more than three years have passed since treatment.

5. Continued treatment “tolling”

When the same healthcare provider continues treating you for the same condition:

  • The statute may potentially not begin running until treatment ends – this is dependent on the circumstances of the situation.
