How does the dual policy—the C-DRG-based reimbursement system and subsidy policy for appropriate Traditional Chinese Medicine (TCM) techniques—influence physicians’ choice of disease treatment methods in TCM hospitals?

The C-DRG-based reimbursement system and subsidy policies positively influenced the treatment methods of TCM orthopaedic physicians, increasing the number of treated cases and reducing expenses. An optimal subsidy of 584.79 RMB was identified to maximize the number of treated patients, aligning with both DRG expenses control and subsidy policy objectives.
