If the injury is complex and does not have the conditions for immediate appraisal, it shall put forward appraisal opinions and issue appraisal documents within 7 days from the date of entrustment. If it affects the function of tissues and organs or the injury is complicated and difficult to identify for a while, it shall timely put forward the appraisal opinions and issue the appraisal documents after the injury is stable.
