With the rapid growth of outpatient medical demands among urban and rural residents, the outpatient fund pooling system has been gradually established. This study analyzes policy documents from selected areas in 31 provincial administrative regions nationwide, systematically examining the characteristics of the outpatient pooling system in terms of financing mechanisms, security levels, and medical service management systems. The results show that financing methods are primarily categorized by whether funds are raised separately and different fund management approaches. Regional disparities exist in security levels, including deductible standards, reimbursement ratios, and maximum payment limits. Although some regions have eliminated single-visit limits to enhance residents' healthcare accessibility, the overall benefit levels remain relatively low, with significant differences among regions. Furthermore, the policy design emphasizing primary care institutions requires to be clarified, and there is a lack of effective coordination in service management across regions. In view of this, it is recommended to strengthen the connection between policies, optimize the allocation of medical resources, and encourage the development of primary medical services to improve the medical experience of insured residents to effectively improve the outpatient security level of urban and rural residents' medical insurance.
