Objective: Beijing has entered a moderately aging society. It provided data support to improve the accuracy and scientific of health policies for the elderly population in the capital by exploring the current situation of the beneficiary population of curative care expenditure (CCE) for the elderly population in Beijing from different sources. Methods: A total of 52 hospitals and 29 communities were selected as samples through a multi-stage stratified whole-group sampling survey. System of Health Accounts 2011 (SHA2011) was used to calculate the CCE of elderly patients in medical institutions of Beijing. Results: The CCE of elderly patients in Beijing was 98.232 billion yuan，accounting for 39.78 %，of which 81.19 %was consumed by local residents in 2019. Residents mainly use outpatient services，while non-residents mainly use the inpatient services of tertiary hospitals. The elderly patients who come to Beijing for medical treatment were relatively young，with CCE between the ages of 60 and 70 accounting for more than 60 %of the total. Elderly patients were mainly suffered from chronic non-communicable diseases and the distribution of diseases was relatively concentrated. Meanwhile，the distribution of diseases of patients from different sources shows obvious differences. Conclusions: Geriatric patients were high demand for healthcare resources and were predominantly suffering from chronic non-communicable diseases. The CCE for elderly patients from different sources varied significantly by ages，diseases，and institutional flows，and health policies should take into account the needs of different patients precisely.
