Procedural Trends in Medicare Reimbursement and Utilization for Breast Reconstruction: 2000-2019.

[PURPOSE] Development of appropriate reimbursement models for breast reconstruction in the United States requires an understanding of relevant economic trends. The purpose of this study is to evaluate longitudinal patterns in Medicare reimbursement for frequently performed breast reconstruction procedures between 2000 and 2019.

[METHODS] Reimbursement data for 15 commonly performed breast reconstruction procedures were analyzed using the Centers for Medicare & Medicaid Services Physician Fee Schedule Look-Up Tool for each Current Procedural Terminology code. By utilizing changes to the US consumer price index, monetary data were adjusted for inflation to 2019 US dollars. Inflation-adjusted trends were used to calculate average annual and total percentage changes in reimbursement over time.

[RESULTS] From 2000 to 2019, average adjusted reimbursement for all procedures fell by 13.32%. All procedures demonstrated a negative adjusted reimbursement rate other than immediate insertion of breast prosthesis, which increased by 55.37%. The largest mean decrease was observed in breast reconstruction with other technique (-28.63%), followed by single pedicle transverse rectus abdominis myocutaneous flap (-26.02%), single pedicle transverse rectus abdominis myocutaneous flap with microvascular anastomosis (-23.33%), latissimus dorsi flap (-19.65%), and free flap reconstruction (-19.36%).

[CONCLUSIONS] There has been a steady yet substantial decline in Medicare reimbursement for the majority of breast reconstruction procedures over the last 20 years. Given increasing medical costs and the financial uncertainty of the US health care system, an understanding of Medicare reimbursement trends is vital for policymakers, administrators, and physicians to develop agreeable reimbursement models that facilitate growth and economic vitality of breast reconstruction in the United States.
