Trends in payments for facility and surgeon professional fees for shoulder surgeries performed at ambulatory surgery centers.

Abstract

Background: It has previously been demonstrated that utilization of ambulatory surgery centers (ASCs) results in cost savings and improved outcomes. Despite these benefits, Medicare reimbursement for professional fees at ASCs are decreasing over time. In this study, we sought to analyze the discrepancy between facility fee and professional fee reimbursements for ASCs by Medicare for common shoulder procedures over time. We hypothesized that professional fees for shoulder procedures would decrease over the study period while facility fees kept pace with inflation.

Methods: Current Procedural Terminology codes were used to identify shoulder specific procedures approved for ASCs by Centers for Medicare and Medicaid Services. Procedures were grouped into arthroscopic and open categories. Publicly available data from Centers for Medicare and Medicaid Services was accessed via the Medicare Physician Fee Schedule Lookup Tool and used to determine professional fee payments from 2018 to 2024. Additionally, Medicare ASC Payment Rates files were accessed to determine facility fee reimbursements to ASCs from 2018 to 2024. Descriptive statistics were used to calculate means and percent change over time. Compound annual growth rates were calculated and discrepancies in inflation were corrected for using the Consumer Price Index. The Benjamini and Hochberg method was used to correct P values in the setting of multiple comparisons.

Results: A total of 33 common shoulder procedures were included for analysis (10 arthroscopic codes and 23 open codes). Reimbursements for facility fees have remained significantly higher than corresponding professional fees for both open and arthroscopic procedures (P < .01). On average, facility fee reimbursements for common shoulder surgeries have risen on an annual basis in a manner consistent with inflation (P = .838). However, professional fees for these procedures have experienced a nearly uniform decline over the study period both nominally and in inflation-adjusted dollars (P = .064 and P = .005, respectively).

Conclusion: Facility fee payments for outpatient approved shoulder surgeries have matched or outpaced inflation. Over the same time period, professional fee reimbursements for surgeons are consistently decreasing, both in absolute and inflation-adjusted dollars. Reform to the physician fee schedule is necessary to ensure that Medicare patients retain access to high-quality physician care.
