To characterize the relationship between office-based laboratory (OBL) use and Medicare payments for peripheral vascular interventions (PVI). Using the Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use Files from 2014 to 2017, we identified providers who performed percutaneous transluminal angioplasty, stent placement, and atherectomy. Procedures were aggregated at the provider and hospital referral region (HRR) level. Between 2014 and 2017, 2641 providers performed 308,247 procedures. The mean payment for OBL stent placement in 2017 was $4383.39, and mean payment for OBL atherectomy was $13,079.63. The change in the mean payment amount varied significantly, from a decrease of $16.97 in HRR 146 to an increase of $43.77 per beneficiary over the study period in HRR 11. The change in the rate of PVI also varied substantially, and moderately correlated with change in payment across HRRs (R2 = 0.40; P < .001). The majority of HRRs experienced an increase in rate of PVI within OBLs, which strongly correlated with changes in payments (R2 = 0.85; P < .001). Furthermore, 85% of the variance in change in payment was explained by increases in OBL atherectomy (P < .001). A rapid shift into the office setting for PVIs occurred within some HRRs, which was highly geographically variable and was strongly correlated with payments. Policymakers should revisit the current payment structure for OBL use and, in particular atherectomy, to better align the policy with its intended goals.
