Effects of Medicaid expansion on postpartum coverage and outpatient utilization.
Timely postpartum care is associated with lower maternal morbidity and mortality, yet fewer than half of Medicaid beneficiaries attend a postpartum visit. Using Medicaid claims data for 2013-2015 from Colorado, which expanded Medicaid under the Affordable Care Act, and Utah, which did not, the authors conclude that expansion may promote the stability of postpartum coverage and increase the use of postpartum outpatient care in the Medicaid program.

Where do Oregon Medicaid Enrollees seek outpatient care post-Affordable Care Act Medicaid expansion?
The purpose of this study was to understand where Oregon Medicaid beneficiaries sought care after the Patient Protection and Affordable Care Act Medicaid expansion (emergency department, primary care, or specialist) and the interaction between primary care establishment and outpatient care utilization. Results showed that most newly and returning-insured Medicaid enrollees sought primary care rather than emergency department services and most became established with primary care, suggesting that both insurance and primary care continuity play a role in where patients seek health care services.

Following uninsured patients through Medicaid expansion: ambulatory care use and diagnosed conditions.
The authors assessed ambulatory care use and diagnosed health conditions among a cohort of community health center (CHC) patients uninsured before enactment of the Affordable Care Act (ACA) and followed them after enactment. They found that, post-ACA, 20.9% of patients remained uninsured, 15.0% gained Medicaid, 12.4% gained other insurance, and 51.7% did not have a visit. The authors concluded that a significant percentage of CHC patients remained uninsured; that many who remained uninsured had diagnosed health conditions; and that one-half continued to have three or more visits to CHCs, which continue to be essential providers for uninsured patients.

Impact of Medicare office visit payment reform on urologic practices.
This study analyzed the impact of the 2019 Medicare Physician Fee Schedule on urologic practices. This new payment system modifies reimbursement for office evaluation and management visits. Researchers used a sample of 20% of National Medicare claims. They identified 2822 practices ranging from solo to multispecialty groups. Solo practices had the least benefit in reimbursement with most practices having a small increase in payment.

Effects of the Medicare Modernization Act on spending for outpatient surgery.
The objective of the study was to examine the effects of Medicare's revised ambulatory surgery center (ASC) payment schedule on overall payments for outpatient surgery. The study concluded that despite lessening demand, reduced ASC facility payments did not curb spending for outpatient surgery. In fact, overall payments actually increased following the policy change, driven by higher average episode payments.

Assessing the reach of health reform to outpatient surgery with social network analysis.
The researchers used the tools of social network analysis to assess the proportion of outpatient surgery currently delivered in ambulatory surgery centers (ASCs) that are largely unconnected to nearby hospitals. Their study of all Florida ASCs and hospitals found that 83% of the $4.3 billion in charges for ASC-based care originate from facilities that have substantial integration with their local health care systems.
