ABSTRACT:

Objective

To determine the relationship between Medicare's site-based outpatient billing policy and hospital-physician integration.

Data sources

National Medicare claims data from 2010 to 2016.

Study design

Using logistic regression analysis, we estimated the relationship between these payment differences and hospital-physician integration, adjusting for region, market concentration, and time fixed effects.

Data collection

The study included integrated and non-integrated physicians who billed Medicare between January 1, 2010, and December 31, 2016 (n = 2
