A biomedical simulation system determines, based on biomedical information specific to a patient, whether to perform biomedical simulation, and generates a biomedical model of a particular organ of the patient based on the biomedical information when having determined to perform the biomedical simulation. Next, the biomedical simulation system executes, based on the biomedical model, the biomedical simulation of post-operative conditions of the patient's particular organ following an operation performed on the patient and determines whether results of the biomedical simulation meet a predetermined improvement rate associated with symptoms. The biomedical simulation system determines, when the results of the biomedical simulation do not meet the predetermined improvement rate, not to reimburse medical treatment costs for the operation of the patient. When the results of the biomedical simulation meet the predetermined improvement rate, the biomedical simulation system decides to perform the operation on the patient.
