Illinois Deadlines for a Gallbladder Claim
Illinois gives you two years from the date you knew, or reasonably should have known, of the injury to file against a physician, nurse or hospital. The same statute sets an outer limit of four years from the act or omission that caused it.
That outer limit runs from the surgery even if nobody told you what went wrong. Waiting to see whether symptoms settle can therefore cost you the claim itself, which is why we look at the dates first.
A child's claim follows a separate rule: the action may be brought up to eight years after the act, but never after the child's 22nd birthday.
