Time limits are generally governed by laws called "statutes of limitations." Each state specifies a different statute of limitations for different kinds of claims. In some states, claims for medical negligence must be brought within a year of the injury.
Additionally, different circumstances cause the time period to begin running sooner or later than in other types of cases. As a general rule, these issues can be factually complex and legally complicated, and it is in your best interest to proceed without delay.
Because of your specific circumstances, you should contact a Minnesota lawyer directly and speak with him or her about your case. That is the only way you can know for sure if you still have time to file a claim to protect your rights. Most medical malpractice attorneys offer free consultations, and can discuss your options with you. My advice is to find someone you feel comfortable with and contact them directly. Good luck!
If strictly medical malpractice and not combined with wrongful death than 2 year under Missouri law. If wrongful death resulting from medical malpractice then 3 years in Missouri. However, statute of limitations is more complicated than that simple answer, there are issues that "toll" the statute of limitations, such as continuing care exception, if the plaintiff was a minor at the time of the negligent act - see:
