Mental health service utilization review patterns in a Medicaid managed care program

Area of Science:

• Health Services Research
• Public Health
• Mental Health Services

Background:

• Utilization review (UR) is a critical process in managed care to ensure appropriate healthcare services.
• Understanding UR practices in mental health is essential for quality care and resource allocation.
• Medicaid managed care organizations (MMCOs) play a significant role in delivering mental health services to vulnerable populations.

Purpose of the Study:

• To investigate clinical service authorization requests, denials, and denial reasons within a statewide MMCO program for mental health services.
• To determine utilization review denial rates and identify the most common reasons for denials in mental health care.
• To provide data for potential reforms in UR processes to improve mental health care delivery.

Main Methods:

• Retrospective analysis of utilization review data from 15 MMCOs in New York State.
• Data collected for calendar years 2017 and 2018, focusing on mental health services.
• Analysis of authorization requests, clinical denials, and specified reasons for denial.

Main Results:

• A total of 264,901 inpatient and 53,687 outpatient mental health service authorization requests were analyzed.
• Denial rates were 1.5% for inpatient and 0.4% for outpatient requests, primarily due to medical necessity.
• The leading cause for inpatient mental health service denials was failure to meet the requested level of care standards.

Conclusions:

• Low utilization review denial rates suggest a need for further research into the relationship between UR, quality of care, and patient outcomes in mental health.
• Findings may inform potential reforms to UR systems to reduce costs and enhance care for individuals with mental illness.
• Optimizing UR processes could lead to more efficient resource utilization and improved mental health care delivery.
