Facility-Based Measurement in the Merit-Based Incentive Payment System: A Potential Safety Net for Which Most Radiologists Will Be Eligible.

The purpose of this study was to assess the percentage and characteristics of radiologists who meet criteria for facility-based measurement in the Merit-Based Incentive Payment System (MIPS). The Provider Utilization and Payment Data: Physician and Other Supplier Public Use File was used to identify radiologists who bill 75% or more of their Medicare Part B claims in the facility setting. Among 31,217 included radiologists nationwide, 71.0% met the eligibility criteria for facility-based measurement as individuals in MIPS. The percentage of predicted eligibility was slightly higher for male than female radiologists (72.9% vs 64.5%). The percentage decreased slightly with increasing years in practice (from 78.8% for radiologists with < 10 years in practice to 67.3% for radiologists with ≥ 25 years in practice). The eligibility percentage was also higher for radiologists in rural as opposed to urban practices (81.6% vs 71.3%) and in academic as opposed to nonacademic practices (77.2% vs 70.3%). However, the percentages were similar across practices of varying sizes. There was also a greater degree of heterogeneity by state, ranging from 50.9% in Minnesota to 94.0% in West Virginia. By overall geographic region, the percentage of predicted eligibility was lowest in the Northeast (64.7%) and highest in the Midwest (78.3%). A higher percentage of generalists met the 75% facility-based threshold than did subspecialists (77.3% vs 65.4%). When stratified by subspecialty, however, facility-based eligibility was lowest for musculoskeletal radiologists (38.1%) and breast imagers (45.1%) and highest for cardiothoracic radiologists (85.1%). For other subspecialties, predicted eligibility ranged from 66.0% to 77.8%. Most radiologists will be eligible for facility-based reporting for MIPS in 2019, with some variation by demographic and specialty characteristics. The facility-based option provides a safety net for radiologists who face challenges accessing hospital data for reporting quality measures. In general, radiologists should not alter their current MIPS strategy but should instead consider facility-based measurement as a contingency plan that could result in a higher final score.
