Medical Corporation, separated into two types under Medical Care Act as either medical foundation constituted as a juristic person or non-profit medical corporation, has played a significant role in Taiwan health care system. Proper financial management of the Medical Corporation and effective supervision from the regulatory body are essential to the national health insurance system with further implication to our national health; therefore, a specific chapter is established in the Medical Care Act for this purpose. We studied the most current and relevant regulations related to Medical Care Act with the purpose to raise the financial transparency of the Medical Corporation and improve the regulatory supervising responsibility of Department of Health to the Medical Corporation. We suggest that Article 34 of Medical Care Act may add the outsourcing regulation of the auditing of Medical Corporation by Certified Public Account (CPA) and publication of the resulting financial status. For non-profit Medical Corporation that has accumulated huge profit without any specific expenditure planning from previous fiscal years, we also suggest adding in Article 46 that no less than 80% of the profit from previous fiscal year should be used for social medical aids to fulfill its social responsibility. To properly execute the expenditure for medical aid and research and development purpose, we recommend changing transferring estimated surplus from budgeted revenue into a separated account as the calculated base in the current article to the real surplus in the audited financial report from previous fiscal year. On the supervising operation side from the Department of Health toward the Medical Corporation, we suggest to establish the Standard Operation Procedure for Uniformity of Accounting System for the Medical Corporation as well as the Internal Auditing Guidance so that Medical Corporate could comply with it for healthier financial function. To better meet the special features of Medical Corporation and the requirement by Medical Care Act, there is a need to establish Guidance for the Certified Financial Report by CPA and to amend the current financial review committee (establish under Department of Health) guideline to legalize this certification process for more effective supervision. Contents of the public financial report should also be simplified to enhance the level of understanding to raise the supervising efficacy from the general public.
