Article 19 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of Laws in the Trial of Personal Injury Compensation Cases stipulates that "medical expenses shall be determined according to receipts and vouchers such as medical expenses and hospitalization expenses issued by medical institutions, combined with medical records, diagnosis certificates and other relevant evidence. If the obligor for compensation disagrees with the necessity and rationality of the treatment, he shall bear the corresponding burden of proof. "
"The amount of compensation for medical expenses shall be determined according to the amount actually incurred before the end of the debate in the court of first instance. The obligee can sue separately after deducting the necessary rehabilitation expenses, appropriate cosmetic expenses and other follow-up treatment expenses of organ function recovery training. However, according to the medical certificate or appraisal conclusion, the inevitable expenses can be compensated together with the medical expenses that have already occurred. "
