You can have the strongest medical malpractice case in Colorado, with clear evidence of negligence, testimony from leading medical experts, and devastating injuries, and lose everything if you miss the filing deadline. The statute of limitations in medical malpractice cases is strict, nuanced, and unforgiving. Understanding how it works is not optional.
Key Takeaways
- The basic statute of limitations for medical malpractice in Colorado is two years from the date you discovered (or should have discovered) the injury.
- Colorado has a hard three-year cap from the date of the medical act. After three years, your claim is barred regardless of when you discovered the injury, with limited exceptions.
- The certificate of review requirement adds another deadline. You must file it within 60 days of filing suit, which means medical expert review needs to happen before you file.
The Basic Rule: Two Years
Under C.R.S. 13-80-102.5, a medical malpractice action must be brought within two years after the claimant discovers, or in the exercise of reasonable diligence should have discovered, the injury. This is called the “discovery rule.”
The clock does not necessarily start on the date of the medical procedure or treatment. It starts when you knew or reasonably should have known that:
- You were injured
- The injury was caused by or related to medical treatment
This distinction matters because many medical injuries are not immediately apparent. A misdiagnosis may not become evident until the condition has progressed. A surgical error may not cause symptoms for weeks or months. The discovery rule recognizes this reality.
The Hard Stop: Three Years
Regardless of when you discover the injury, Colorado imposes an absolute three-year deadline from the date of the act or omission that caused the injury. This means even if you could not have reasonably discovered the injury within three years, your claim is generally barred after that point.
There are limited exceptions to this three-year cap:
Foreign Objects
If a surgical instrument, sponge, or other foreign object was left inside your body, the two-year discovery rule applies from the date you discover or should have discovered the object. The three-year absolute cap does not apply in these cases. Some patients do not learn about a retained foreign object for years after the surgery.
Fraudulent Concealment
If the healthcare provider knew about their error and actively concealed it from you, the statute of limitations may be tolled (paused) until you discover or should have discovered the concealment. This requires proving that the provider took affirmative steps to hide the negligence, not merely that they failed to volunteer the information.
Minors
For children, the statute of limitations is modified. A minor’s claim generally does not begin to run until they turn 18, subject to certain limitations. If your child was injured by medical negligence, consult an attorney promptly because the rules for minors interact with other deadlines in ways that can be complicated.
State Law
Under C.R.S. 13-80-102.5, the statute of limitations for medical malpractice is two years from discovery, with a three-year hard cap from the date of the act. Limited exceptions exist for foreign objects left in the body, fraud or concealment by the provider, and claims involving minors.
The Certificate of Review Requirement
Filing a lawsuit within the statute of limitations is not the only deadline that matters. Under C.R.S. 13-20-602, within 60 days of serving the complaint on the defendant, the plaintiff must file a certificate of review signed by the plaintiff’s attorney.
This certificate states that an expert in the relevant medical specialty has reviewed the case and believes the claim has merit. Failure to file a timely certificate of review can result in dismissal of the case.
Because obtaining the expert review takes time, this requirement effectively means you need to begin the legal process well before the statute of limitations deadline, not at the last minute.
When the Clock Actually Starts: Common Scenarios
Misdiagnosis
You visited a doctor with symptoms and were told nothing was wrong. A year later, another doctor discovers advanced cancer that could have been caught earlier. The two-year clock likely starts when the second doctor made the correct diagnosis, because that is when you discovered (or should have discovered) the original provider’s error.
Surgical Complications
You had surgery and experienced complications immediately afterward. You may have been told the complications were normal or expected. The clock may start when you learned, perhaps from another doctor, that the complications were not normal and were caused by a surgical error.
Medication Errors
You were prescribed a medication that interacted with another drug you were taking, causing a serious reaction. The clock likely starts when you or another provider identified the interaction as the cause of your symptoms.
Deadline Warning
The three-year hard cap means that even if you do not discover the malpractice until year four, your claim is likely barred. Consulting an attorney as soon as you suspect something went wrong is critical. An attorney can determine whether any exceptions apply and preserve your right to file.
Why Waiting Is the Biggest Mistake
Every week you wait is a week closer to losing your legal rights permanently. Beyond the statute of limitations itself:
- Medical records may be altered or lost. Providers are required to maintain records, but the longer you wait, the more risk there is of records becoming incomplete.
- Memories fade. Witnesses, including other medical staff who may have observed the error, forget details over time.
- Expert review takes time. Finding and consulting the right medical expert, obtaining all records, and preparing the certificate of review is a process that takes weeks to months.
- Negotiations take time. If the case can be resolved without trial, the negotiation process begins only after the case is fully prepared.
What to Do Right Now
If you suspect you were harmed by medical negligence, take these steps immediately:
- Note the date of the treatment or procedure you believe caused harm
- Note when you first realized something went wrong
- Request copies of your medical records from all providers involved
- Do not discuss the case with the provider who may have committed the error

Frequently Asked Questions
What is the statute of limitations for medical malpractice in Colorado?
Two years from the date you discovered or should have discovered the injury, with an absolute three-year cap from the date of the medical act or omission. Exceptions exist for foreign objects left in the body, fraudulent concealment, and claims involving minors.
What happens if I miss the statute of limitations?
If you file after the statute of limitations has expired, the court will almost certainly dismiss your case, regardless of how strong the evidence is. The deadline is strictly enforced in Colorado. This is why consulting an attorney early is critical.
Does the statute of limitations start from the date of surgery?
Not necessarily. Colorado follows the discovery rule, meaning the clock starts when you knew or should have known about the injury. If a surgical error was not discoverable until months later, the two-year period may start from that later discovery date, subject to the three-year absolute cap.
