Design Highlights
- Managed care does not consistently reduce costs or improve health outcomes, undermining claims of its effectiveness.
- Access to care is limited due to defined provider networks and high prior authorization denial rates.
- Quality of care is compromised, evidenced by higher hospitalization rates for preventable conditions among managed care enrollees.
- Oversight and accountability in managed care systems are lacking, leading to potential improper payments and denials of necessary services.
- Continued investment in managed care represents a costly experiment with questionable results, calling for reconsideration of its viability.
Medicaid managed care is stumbling, and the numbers tell the story. As of July 2025, a whopping 42 states and the District of Columbia have jumped on the managed care bandwagon, locking in about 66 million enrollees—roughly 78% of all Medicaid beneficiaries. That’s a massive chunk of the population relying on what’s supposed to be a streamlined, efficient system. But here’s the kicker: in fiscal year 2024, payments to these all-encompassing risk-based managed care organizations (MCOs) made up about 50% of the total Medicaid spending, which hit a staggering $919 billion. So, is this investment paying off? Spoiler alert: not really.
Medicaid managed care is faltering, with 42 states and D.C. spending half of $919 billion on a system that isn’t delivering results.
A 2018 report from the Congressional Budget Office revealed no consistent evidence that managed care actually cuts costs or improves health outcomes. In fact, many MCO states saw at least 40% of their Medicaid dollars funneled into MCO payments. This raises serious questions. If managed care isn’t cutting costs or improving care, what’s the point? It appears that defined provider networks and cost-containment measures may be doing more harm than good, limiting access to care and compromising quality. Even MACPAC, the Medicaid and CHIP Payment and Access Commission, has pointed out that higher managed care penetration didn’t lead to reduced spending for nondisabled adults. Fundamentally, managed care seems to be a costly experiment that simply isn’t delivering. Additionally, a recent GAO report indicated a zero percent improper payment rate in Medicaid managed care, suggesting a lack of oversight.
Access to care is another major concern. The Health and Human Services Office of Inspector General (HHS OIG) has noted high prior authorization denial rates, which leaves many people scrambling for medically necessary services. Limited oversight means that patients might not even realize they’re being denied care that should be covered. It’s like a game of hide-and-seek, but the stakes are much higher than just a childhood pastime. This is particularly troublesome in rural areas, where traveling 50 to 100 miles for a specialist can feel like a cruel joke. Additionally, improper payments in managed care highlight the need for greater accountability and oversight in the system.
Quality issues persist as well. MACPAC found that enrollees in Florida’s managed care were more likely to end up hospitalized for preventable conditions than those in fee-for-service plans. And in South Carolina, while there was no significant effect on hospitalizations among children, preventable emergency room visits surged. This isn’t just about numbers; it’s about real lives being affected by a system that’s supposed to help them.
Oversight and accountability? Let’s just say they’re a bit lacking. Families USA argued there’s little evidence that MCOs improve access or care coordination. Much like property and casualty insurance, Medicaid managed care policies contain critical exclusions and limitations that can leave enrollees without coverage when they need it most. So, what’s left? A massive, expensive experiment with questionable results. It’s time to face the reality: Medicaid managed care is failing.
