Physicians inevitably face various moral dilemmas in clinical situations. One of them is the inappropriate request from the patient. Patients often ask their physicians to help them deceive the third parties, including insurance units, governmental authorities and private companies, for personal benefit. This paper discusses whether four reasons which are frequently cited in the literature are morally acceptable. These include the following: less difficulty in agreeing to the patient request than refusing, rectifying current unjust health care regulation, serving the benefit of the patient, and promoting trust inherent in the doctor-patient relationship. By considering the purpose and scope of medicine, it is argued that the personal benefit and interests of the patients are not always the morally appropriate objectives which should be pursued by physicians.
