This brief describes nonelderly adults with opioid use disorder, including their demographic characteristics and insurance status, and compares utilization of treatment services among those with Medicaid to those with other types of coverage. It also describes Medicaid financing for opioid treatment and the ways in which Medicaid promotes access to treatment for enrollees with OUD.
This brief provides an overview of the status of the health care systems and Medicaid programs in Puerto Rico and the U.S. Virgin Islands (USVI) about one and a half years after Hurricanes Irma and Maria struck the islands in September 2017. The hurricanes exacerbated the territories’ existing economic and health care challenges by accelerating outmigration of residents and health care providers and destroying homes, schools, health care facilities, and other infrastructure.

This analysis examines how health insurance deductibles are affecting consumers with employer-sponsored insurance.

The pilots will address housing instability, transportation insecurity, food insecurity, and interpersonal violence and toxic stress for a limited number…
Individual market insurers are expecting to return to consumers a record total of about $800 million in medical loss ratio rebates for 2018, a year in which the insurance companies posted their best annual financial performance under the Affordable Care Act to date. Financial results for 2018 suggest that insurers in the individual market are generally returning to or exceeding profitability levels seen before 2014, when ACA insurance market rules took effect, including the requirement…
The analysis finds that people who switched from traditional Medicare to Medicare Advantage in 2016 had health spending in 2015 that was $1,253 less, on average, than the average spending for beneficiaries who remained in traditional Medicare (after adjusting for health risk). The findings suggest that the current payment method may systematically overestimate expected costs of Medicare Advantage enrollees. Adjusting payments to reflect Medicare Advantage enrollees’ prior use of health services could potentially lower total…
Health Care for the Homeless (HCH) programs, a subset of community health centers, play a significant role in addressing the opioid epidemic by providing medication-assisted treatment (MAT). MAT, which combines one of three medications (methadone, buprenorphine, or naltrexone) with behavioral therapies, is the standard of care for opioid use disorder (OUD). This brief presents findings from an analysis of health center data on the provision of buprenorphine-based MAT, as well as interviews with providers and…
