From 1991 to 2009, the fraction of Medicaid recipients enrolled in HMOs and other forms of Medicaid managed care (MMC) increased from 11 percent to 71 percent.

Which areas of spending are differentially affected by managed care enrollment and whether savings from managed care affect Medicaid design, specifically coverage generosity are identified, show reductions in Medicaid spending larger than previously found in cross-state studies.

Health Insurance Generosity and Conditional Coverage: Evidence from Medicaid and Managed Care in Kentucky

The findings suggest that the introduction of MMC increases the likelihood of being uninsured and decreases formal Medicaid participation, consistent with an increase in “conditional coverage” – waiting until medical care is needed to sign up or re-enroll in Medicaid.

Heterogeneity in the Impact of Privatizing Social Health Insurance: Evidence from California's Medicaid Program

Do the Poor Benefit from More Generous Medicaid Policies?

Medicaid managed care and preventable emergency department visits in the United States

It is found that the type of Medicaid held by a recipient, i.e., whether an HMO or FFS coverage, was unrelated to the probability that an ED visit was potentially preventable, and this finding emerged both among dual eligibles and among non-duals.

Do the Poor Benefit From More Generous Medicaid Physician Payments?⇤

Do Insurers Risk-Select Against Each Other? Evidence from Medicaid and Implications for Health Reform

A simple model of risk-selection in capitated private health plans incentivizes insurers to retain low-cost clients and thus improve their care relative to high- cost clients, who they prefer would switch to a competitor.

Utilization of and Relationships With Primary Care Providers During the Transition to Medicaid Managed Care

Regression analyses showed that enrollment in MMC was significantly related to each of the three outcomes; MMC enrollees were more likely than the FFS group to see a PCP during the 1-year post-period and have high levels of continuity of care with a single PCP.

National Estimates of the Effects of Mandatory Medicaid Managed Care Programs on Health Care Access and Use, 1997–1999

Effects of Medicaid managed care programs on health services access and use.

Using HMOs to serve the Medicaid population: what are the effects on utilization and does the type of HMO matter?
