Effects of the Affordable Care Act on Payer Mix and Physician Reimbursement in Hand Surgery.

Purpose: To evaluate the effect of the Affordable Care Act (ACA) on the payer distribution and reimbursement rate for hand surgery at our institution.
Methods: We reviewed records of 4,257 patients who underwent hand surgery at our institution between January 2008 and June 2016; 2,601 patients underwent surgery before the implementation of the ACA, and 1,656 patients after. Type of procedure, insurance status, amount of money billed, and amount collected were recorded.
Results: After the implementation of the ACA, we performed fewer metacarpal fracture repairs, distal radius fracture repairs, and abscess incision and drainage procedures. We performed more endoscopic carpal tunnel releases. The proportion of uninsured patients decreased significantly (15% to 6.4%), and the proportion of patients on Medicare (15.4% to 20.3%) and Medicaid (9.5% to 17.8%) increased significantly. The overall reimbursement rate did not change significantly (32.3% to 30.3%) between the 2 time periods.
Conclusions: After the implementation of the ACA, we observed a significant reduction in the number of uninsured patients and an increase in Medicaid and Medicare patients. However, this led to no significant change in reimbursement rates.
Type of Study/level of Evidence: Economic and design analysis II.
