Trends in Diagnostic Point-of-Care Ultrasonography Reimbursement for Medicare Beneficiaries Among the US Emergency Medicine Workforce, 2012 to 2016.

Point-of-care ultrasonography allows rapid diagnosis in the emergency department. A previous study found that a low prevalence of emergency medicine clinicians received point-of-care ultrasonography reimbursement in 2012 (0.7%). We determine nationwide point-of-care ultrasonography reimbursement patterns for 4 subsequent years. We performed a cross-sectional study using 2012 to 2016 data from the Centers for Medicare & Medicaid Fee-for-Service Provider Utilization and Payment Data Part B, defining point-of-care ultrasonographic examinations using Current Procedural Terminology codes. The emergency medicine workforce was defined by emergency medicine, family medicine, internal medicine, critical care, and advanced practice providers who received emergency medicine-specific reimbursements. We compared patterns of point-of-care ultrasonography reimbursement among emergency physicians in 2012 versus 2016 through a 2-sample test of proportions. In 2012, 342 (0.7% of total) emergency medicine workforce clinicians were reimbursed for diagnostic point-of-care ultrasonography versus 801 (1.3%) in 2016. Emergency physicians represented an increasing proportion of the total workforce, increasing from 86.0% (95% confidence interval 82.3% to 89.6%) in 2012 (N=294) to 94.6% (95% confidence interval 93.1% to 96.2%) in 2016 (N=758). From 2012 to 2016, total point-of-care ultrasonography reimbursements increased from 13,697 to 31,717, with significant growth from echocardiograms (4,127 to 14,978), abdominal examinations (3,682 to 7,140), and thoracic examinations (801 to 5,278). The proportion of emergency medicine workforce clinicians receiving diagnostic point-of-care ultrasonography reimbursements, as well as the number of point-of-care ultrasonographic studies, more than doubled from 2012 to 2016. Efforts are needed to understand barriers to adoption of point-of-care ultrasonography because only a small proportion of the emergency medicine clinician workforce was reimbursed in any year.
