For years, debates over Medicaid spending have centered on one question: Does paying doctors more simply increase healthcare costs? New research suggests the answer may be more complicated. A study from the City University of New York Graduate School of Public Health and Health Policy found that states paying psychiatrists higher Medicaid reimbursement rates actually saw lower overall healthcare costs for adults with serious mental illness.
The findings, published in the June issue of the American Journal of Managed Care, suggest that improving access to outpatient mental healthcare may help reduce expensive hospitalizations and emergency department visits, challenging the long-held assumption that higher provider payments always translate into higher spending.
Why This Matters For Patients
Better reimbursement may encourage more psychiatrists to accept Medicaid.
Improved access can help patients receive treatment before a mental health crisis develops.
Fewer emergency department visits could lower overall healthcare spending.
Patients may have more provider choices and shorter wait times in states with stronger participation.
Researchers Examined Millions of Medicaid Records
Mental healthcare access has long been a challenge for Medicaid beneficiaries because many psychiatrists limit the number of Medicaid patients they see or choose not to participate in the program at all. Lower reimbursement rates can make it financially difficult for some practices to accept Medicaid, particularly in areas already experiencing provider shortages. Improving payment rates may encourage more psychiatrists to participate, reducing wait times and expanding access to routine mental healthcare.
The study analyzed Medicaid claims from more than 44 million patients and over 900 million healthcare claims, making it one of the largest analyses of psychiatrist reimbursement and healthcare utilization to date. Researchers compared states with relatively high Medicaid payment rates for psychiatrists against states with lower reimbursement levels while accounting for differences in patient demographics, health conditions, and state Medicaid policies.
After those adjustments, patients in higher-paying states experienced 24% lower total annual healthcare costs and 19% lower psychiatric-specific healthcare costs than those in lower-paying states. They also had fewer psychiatric emergency department visits and inpatient hospitalizations, suggesting that better access to outpatient care may reduce the need for costly crisis treatment.
It’s important to note that the study focused specifically on adults with serious mental illness, including conditions such as schizophrenia, bipolar disorder, and severe major depression. Because these illnesses often require long-term treatment and regular follow-up, improving access to outpatient psychiatric care may have an especially large impact on preventing costly hospitalizations and emergency visits.
Why Paying More Up Front May Save Money Later
At first glance, increasing Medicaid reimbursement might appear to increase government spending because physicians receive higher payments for each visit. However, the study suggests that higher payments may encourage more psychiatrists to participate in Medicaid, making it easier for patients to receive timely treatment before their conditions worsen.
Regular access to outpatient care can help patients manage serious mental illness through medication management, therapy, and routine follow-up appointments instead of relying on emergency departments during a crisis.
Emergency departments are designed to treat acute medical crises and operate around the clock with specialized staff and equipment. As a result, even non-life-threatening conditions treated in the emergency department generally cost substantially more than the same care delivered in a physician’s office or outpatient clinic. Reducing avoidable emergency visits has therefore become a major focus of healthcare cost-containment efforts.
The Findings Come With an Important Caveat
The researchers emphasized that the study found an association, not proof that higher reimbursement directly causes lower healthcare spending. Other factors, including differences in healthcare systems and state policies, may also influence outcomes. Lead researcher Dr. Onur Baser noted that the results could reflect improved provider participation and better continuity of care in states where psychiatrists are paid more to treat Medicaid patients. Even so, the consistency of the findings across a very large patient population suggests reimbursement policy deserves closer attention as states consider ways to improve access while controlling long-term costs.
Even if reimbursement rates increase, many communities continue to face shortages of psychiatrists and other behavioral health professionals. Payment reform alone is unlikely to solve access challenges, but researchers say it may be one important tool for attracting more providers to Medicaid and improving continuity of care.
CMS Is Also Shifting Toward Value-Based Care
The research arrives as the Centers for Medicare & Medicaid Services continues pursuing payment reforms that reward better health outcomes instead of simply paying for a higher volume of services. CMS recently proposed updates to physician payment policies that place greater emphasis on primary and preventive care, reflecting a broader effort to reduce expensive treatments that become necessary when illnesses are allowed to progress.
Programs such as Accountable Care Organizations already encourage providers to coordinate care, manage chronic conditions earlier, and avoid preventable hospitalizations whenever possible. While Medicare and Medicaid operate differently, both programs increasingly share the goal of improving patient outcomes while slowing the growth of healthcare spending.
What Medicaid Patients Should Take Away
Most Medicaid beneficiaries will never notice changes in provider reimbursement rates directly, but they may notice their effects over time. Higher participation among physicians can mean shorter wait times, more provider choices, and better access to routine care, particularly for patients managing chronic physical or mental health conditions. Establishing an ongoing relationship with a primary care physician or mental health provider can help reduce the likelihood of needing emergency treatment, regardless of how reimbursement policies evolve.
The study underscores a growing shift in healthcare policy: instead of judging payment reforms solely by what they cost today, policymakers are increasingly evaluating whether those investments improve access, prevent costly complications, and lower spending over time. As CMS continues expanding value-based payment models, research like this may influence how states design future Medicaid reimbursement policies.
