Legal basis: Interpretation of the Supreme People's Court on the Trial of Personal Injury Compensation Cases.

Article 17 If the victim suffers personal injury, the compensation obligor shall compensate all expenses such as medical expenses and reduced income caused by absenteeism, including medical expenses, lost time, nursing expenses, transportation expenses, accommodation expenses, hospital food subsidies and necessary nutrition expenses.

If the victim is disabled due to injury, the compensation obligor shall also compensate the necessary expenses incurred due to the increase of daily needs and the income loss caused by the loss of working ability, including disability compensation, disability AIDS, living expenses of the dependents, and necessary rehabilitation expenses, nursing expenses and follow-up treatment expenses actually incurred due to rehabilitation nursing and continuing treatment.

If the victim dies, the compensation obligor shall, in addition to compensating the relevant expenses stipulated in the first paragraph of this article according to the rescue and treatment, also compensate the funeral expenses, living expenses of the dependents, death compensation and other reasonable expenses such as transportation, accommodation, lost time and so on for the funeral expenses of the relatives of the victim.

Nineteenth medical expenses are determined according to the receipts of medical expenses and hospitalization expenses issued by medical institutions, combined with medical records and 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.
