The injury notification must be filled with the Patient Insurance Centre within three years of the date when the injured party first knew, or should have known, of the injury. The limitation period does not start at the point of treatment, but at the point when the injured party understood or should have understood that the injury resulted from the medical treatment and health care received.

The injury notification may be filled later under special circumstances. However, the claim must be made no later than ten years after the treatment if the treatment has been given on 1 May 1999 or after. The absolute limitation period for treatment given before 1 May 1999 is 20 years. If the absolute limitation period has ended, it makes no difference when the patient became aware of the injury. Notifications filled in after the expiry of the absolute limitation period will not be examined.
