Abstract:
This paper studies hospital responses to a diagnosis-based payment scheme with a global budget by exploiting a 2016 policy reform in China. Using administrative data and a difference-in-differences approach, we find hospitals responded through multiple channels: upcoding cases, raising the shares of admissions in categories with higher upcoding potential, and increasing the total number of admissions. As a result of hospitals’ heterogeneous responses, the disparity in hospital payments had widened, and the increase is mainly driven by heterogeneous upcoding behaviors across hospitals. Hospitals that are more knowledgeable about upcoding, more exposed to the reform, and larger upcode cases more aggressively.
