Physician Reimbursement for Vascular Surgery Procedures and Vascular Laboratory Studies Before and After the Affordable Care Act.

ABSTRACT

OBJECTIVES: The Patient Protection and Affordable Care Act (ACA), fully implemented by 2015, has significantly increased the number of Americans with health insurance. However, its impact on physician reimbursement (PR) is not well studied. Our objective was to determine the ACA's impact on the professional component of PR for selected vascular surgery (VS) procedures and vascular laboratory (VL) studies at our institution. METHODS: PR for the following 5 VS procedures and 4 VL studies were obtained from our billing department CPT 34803 (Endovascular aortic repair, EVAR), 35301 (carotid endarterectomy, CEA), 35656 (lower extremity bypass, LEB), 36010 (introduction of catheter into vena cava, ICVC), 36200 first, 93922 (ankle brachial index, ABI), 93925 (lower extremity arterial duplex, LEA duplex), 93970 (lower extremity venous duplex, LEV Duplex), and 93990 (hemodialysis duplex). The data was organized by payer Medicare, Medicaid, Commercial Insurers (CI), and Other. PR was studied pre-ACA (January 2008 through December 2009) and post-ACA (January 2015 through December 2016). The post-ACA PR and inflation adjusted reimbursement (IAR) in 2016 dollars using the consumer price index (CPI) were calculated and compared using one-sample t-test. The percent difference between the post-ACA PR and IAR was also compared. RESULTS: PR for 1,637 VS procedures and 16,333 VL studies was analyzed. The post-ACA PR was significantly lower than the IAR for most Medicare and Medicaid procedures. For EVAR, post-ACA reimbursement was overall on par with the IAR but significantly lower for Medicare. For CEA, post-ACA reimbursement was overall lower than IAR. For LEB, overall average PR was lower than IAR, with statistically significant lower Medicare and Medicaid (P < 0.001) payments. For ICAo, overall PR was significantly lower than the IAR and this was true across all insurance types. In contrast, for ICV, the post-ACA reimbursement was higher than IAR for all payers but did not reach statistical significance (P = 0.25). The post-ACA PR was significantly higher than the IAR for most VL studies, except for Medicare PR. The percent change for VS procedures were mostly negative for the Medicaid and Medicare groups. This results in potential annual shortcomings of $2, 862 and $20,923 respectively. CONCLUSION: When comparing reimbursement before and after ACA implementation, Medicare and Medicaid PR for most VS procedures has not kept up with inflation. However, for most VL procedures, PR has exceeded inflation. Further efforts are needed to support Vascular Surgery reimbursement including higher valuation of the Medicare Conversion factor.
