Out-of-Pocket Costs for Advanced Imaging Across the US Private Insurance Marketplace.

PURPOSE

The aim of this study was to characterize out-of-pocket patient costs for advanced imaging across the US private insurance marketplace.

METHODS

Using the 2017 CMS Health Insurance Marketplace Benefits and Cost Sharing Public Use File, which details coverage policies for qualified health plans on federally facilitated marketplaces, measures of out-of-pocket costs for advanced imaging and other essential health benefits were analyzed for all 18,429 plans.

RESULTS

Independent of deductibles, 48.0% of plans required coinsurance (percentage fees) for advanced imaging, 9.7% required copayments (flat fees), and 8.0% required both; 34.3% required neither. For out-of-network services, 91.5% required coinsurance, 0.1% copayments, and 1.0% both; only 7.4% required neither. In the presence of deductibles, patient coinsurance burdens for advanced imaging in and out of network were 27.7% and 47.7%, respectively, and average in- and out-of-network copayments were $319 and $630, respectively. In the presence of deductibles, patients' average coinsurance ranged from 10.0% to 40.9% in network and from 29.1% to 75.0% out of network by state; these tended to be higher in lower income states (r = -0.332). For no-deductible policies, patients' average out-of-network coinsurance burden for advanced imaging was 99.9%. Among assessed benefits, advanced imaging had the highest in-network and second highest out-of-network copayments.

CONCLUSIONS

In the US private insurance marketplace, patients very commonly pay coinsurance when undergoing advanced imaging, both in and out of network. But out-of-network services usually involve drastically higher patient financial responsibilities (potentially 100% of examination cost). To more effectively engage patients in shared decision making and mitigate the hardships of surprise balance billing, radiologists should facilitate transparent communication of advanced imaging costs with patients.
