Objectives: To assess trends in the medical loss ratio (MLR) and understand how health insurance premiums in the large group market are driven by medical claims spending and insurer margins.
Study Design: Study of approximately 500 insurers covering more than 40 million lives annually in the large group market that submitted an MLR submission form (2014-2022).
Methods: We assessed trends in the MLR, premiums, medical claims spending, administrative costs, quality improvement spending, and margins among all insurers in the large group market.

Objective: To understand how Medicare Advantage (MA) networks impact utilization patterns and plan choices, using the 2019 discontinuation of MA 1876 Cost plans as a natural experiment.
Study Setting And Design: We study 1876 Cost plans, MA plans for which out-of-network care is covered through traditional Medicare (TM) and many of which CMS discontinued in 2019. We characterize the proportion of Cost plan enrollees who utilized out-of-network care in 2018 from different types of medical specialties.

We compared the generosity of Medicare plans in terms of out-of-pocket costs attributable to cost sharing and premiums, including both basic and supplemental services. From 2014 through 2019, projected out-of-pocket costs for a typical enrollee were 18-24 percent lower in Medicare Advantage than traditional fee-for-service Medicare.

This study describes shifts in the distribution and seasonality of plan and patient out-of-pocket spending from 2012 through 2021.

As the Medicare Advantage (MA) program grows in enrollment and costs, there has been increasing concern that federal payments to MA plans exceed necessary levels. Estimates suggest that, in 2023, MA plans were paid up to 6% more per enrollee than would have been spent had that beneficiary instead enrolled in traditional Medicare (TM). We evaluated the factors driving this overpayment, characterizing trends in MA benchmarks, bids, and total payments from pre-Affordable Care Act (pre-ACA) levels through 2023.

Study Design: Cross-sectional study of Health Care Cost Institute commercial claims.
Methods: The study sample comprises 1,379,300 deliveries among high-deductible health plan enrollees in years 2012 through 2021.
Recent price transparency laws are designed to better inform patients as they compare hospital options and "shop" for health care services. In addition to prices, underinsured patients seeking care need information on financial assistance, discounts, payment plans, and upfront payment requirements to compare the affordability of care across hospitals. Little is known about the availability of this information and the experience of prospective patients seeking it.

Using Centers for Medicare & Medicaid Services data, we evaluate the growth in rebates and concomitant changes in supplemental benefit composition among health maintenance organizations (HMOs) and local preferred provider organizations (PPOs) from 2011 through 2022. Average rebates grew considerably, particularly after 2015 and among PPOs.

MA plans were afforded 2 years of lead time for strategizing, negotiating, and capital investment prior to the start date (January 1, 2020) of the new coverage option. Our data analysis found basic benefit telehealth was offered by plans comprising 71% of enrollment in 2020 and increased to 95% in 2021.

Objectives: The share of Medicare stand-alone prescription drug plans with a preferred pharmacy network has grown from less than 9% in 2011 to 98% in 2021. This article assesses the financial incentives that such networks created for unsubsidized and subsidized beneficiaries and their pharmacy switching.

The No Surprises Act prohibits most surprise billing but notably does not apply to ground ambulance services. In this study we created a novel data set that identifies the ownership structure of ground ambulance organizations to compare pricing and billing between private- and public-sector ambulances, with a specific focus on organizations owned by private equity or publicly traded companies. Overall, we found that 28 percent of commercially insured emergency ground ambulance transports during the period 2014-17 resulted in a potential surprise bill.

An understanding of how QPA measures compare with the in-network and out-of-network payments physicians received before the NSA implementation may be useful to policy makers and stakeholders.
Objective: To estimate the QPA for geographic and funding markets and compare QPA estimates with in-network and out-of-network payments for 2019 emergency medicine claims.

Objectives: This study investigates a sample of the pricing data released by hospitals under the price transparency law effective January 2021 to better understand the prices paid by health insurance exchange (HIX) plans relative to commercial group and Medicare Advantage plans.
Study Design: Cross-sectional analysis of hospital pricing data.
Methods: We compared allowed amounts for 25 common inpatient services and 56 common outpatient services across 22 hospital-insurer dyads, selected by the availability of plan-specific pricing data from the top 100 hospitals by bed counts and the top 100 hospitals by gross revenue based on 2017 CMS data.

The 21st Century Cures Act of 2016 lifted regulations prohibiting Medicare Advantage (MA) enrollment after patients initiate dialysis, starting in 2021, and early reports indicate increased MA enrollment among such patients. Large shifts into Medicare Advantage could disrupt the market because the consolidated dialysis industry can negotiate payment from MA plans that is higher than that for fee-for-service Medicare. For three large insurers representing 48 percent of the 2016-17 MA market, we found that MA plans paid 27 percent more than fee-for-service Medicare.

Methods: The authors evaluate prescription drug claims from a 100% sample of Medicare Part D beneficiaries to evaluate the current spending distribution across different payers for different types of beneficiaries across different benefit phases. They then model how these estimates would change under a proposal to redesign the Medicare Part D standard benefit.

Objective: To evaluate the effects of preferred pharmacy networks-a tool that Medicare Part D plans have recently adopted to steer patients to lower cost pharmacies-on the use of preferred pharmacies and factors underlying beneficiaries' decisions on whether to switch to preferred pharmacies.
Data Sources: Medicare claims data were collected for a nationally representative 20% sample of beneficiaries during 2010-2016 and merged with annual Part D pharmacy network files.
Study Design: We examined preferred networks' impact on pharmacy choice by estimating a difference-in-differences model comparing preferred pharmacies' claim share before and after implementation among unsubsidized and subsidized beneficiaries.
