Integrated care is becoming increasingly vital in the healthcare landscape, especially for individuals with complex needs. Medicaid Integrated Care Programs are designed to address these complexities by combining primary care and behavioral health services. A key component in identifying and tracking these programs within healthcare systems is the National Provider Identifier, or NPI. This article delves into what Medicaid Integrated Care Programs are and the significance of the NPI in this context, drawing insights from a comprehensive study on Primary and Behavioral Health Care Integration (PBHCI).
Understanding Medicaid Integrated Care Programs
Medicaid Integrated Care Programs aim to improve the overall health and well-being of individuals, particularly those with Serious Mental Illness (SMI) and substance use disorders. These programs recognize the long-standing divide between physical and behavioral healthcare systems and seek to bridge this gap through coordinated and comprehensive care.
The Need for Integration
Adults with SMI often face significant physical health disparities. They are at higher risk for chronic diseases like diabetes, cardiovascular disease, and respiratory illnesses, leading to a significantly lower life expectancy – sometimes by as much as 8 to 30 years compared to the general population. Contributing factors include:
- Modifiable Risk Factors: Higher rates of smoking, substance abuse, poor diet, and lack of exercise.
- Medication Side Effects: Psychotropic medications can contribute to metabolic issues.
- Socioeconomic Factors: Housing instability and low socioeconomic status limit access to care.
- Fragmented Healthcare: The separation of mental health and physical health services creates barriers to coordinated treatment.
This fragmentation results in poorer health outcomes and increased healthcare costs. Individuals with co-occurring medical and behavioral health conditions are disproportionately high-cost beneficiaries within Medicaid and Medicare systems.
PBHCI: A Grant Program for Integration
The Substance Abuse and Mental Health Services Administration (SAMHSA), a part of the U.S. Department of Health and Human Services (HHS), initiated the Primary and Behavioral Health Care Integration (PBHCI) grant program in 2009. PBHCI grants support community behavioral health centers in integrating primary care and preventive physical health services into their existing mental health and substance abuse treatment settings.

The PBHCI program aims to achieve the “triple aim” of healthcare reform:
- Improved Care Experiences: By offering convenient, co-located, or closely coordinated services.
- Improved Health Outcomes: Addressing both physical and mental health needs comprehensively.
- Reduced Per Capita Costs: Potentially decreasing reliance on expensive emergency department visits and inpatient hospitalizations through proactive primary care.
Key Components of PBHCI Programs
Early PBHCI grantees (cohorts 1-3) were required to implement core program features, including:
- Screening and Referral: Identifying physical health conditions and connecting individuals to appropriate care.
- Registry/Tracking Systems: Monitoring consumers’ physical health needs and outcomes.
- Care Management: Coordinating services and supporting individuals in managing their health.
- Illness Prevention and Wellness Services: Promoting healthy lifestyles and preventive care.
Optional features included co-locating primary care providers within behavioral health settings and embedding nurse care managers within clinical teams. Over time, the PBHCI program has evolved, with later cohorts facing more stringent requirements for on-site primary care, health information technology adoption, and sustainability planning.
The Role of NPI in Identifying Integrated Care Programs
The National Provider Identifier (NPI) is a unique 10-digit identification number for healthcare providers in the United States. Covered healthcare providers and all health plans and healthcare clearinghouses must use NPIs in administrative and financial transactions adopted under HIPAA (Health Insurance Portability and Accountability Act).
In the context of Medicaid Integrated Care Programs, the NPI serves a crucial role in:
- Identifying PBHCI Clinics in Claims Data: Researchers and healthcare administrators use NPIs to locate and analyze Medicaid claims data associated with specific clinics participating in PBHCI programs. By using the NPIs of PBHCI grantee clinics, it’s possible to track the healthcare utilization, costs, and quality of care for individuals served by these programs.
- Distinguishing Integrated Care Providers: NPIs help differentiate between providers offering integrated care and those providing traditional, siloed services. This distinction is vital for evaluating the impact and effectiveness of integrated care models.
- Analyzing Program Impact: As demonstrated in the RAND Corporation’s evaluation of PBHCI, NPIs are essential for conducting clinic-level analyses. By identifying PBHCI and comparison clinics through their NPIs, researchers can compare outcomes and assess the difference integrated care programs make.

Challenges and Considerations in Using Claims Data and NPIs
While NPIs and Medicaid claims data are powerful tools for evaluating integrated care, there are limitations:
- Data Completeness: Medicaid claims data may not capture all services provided, especially those funded directly by grants or services not typically billed to Medicaid (e.g., peer support services initially).
- Managed Care Encounter Data: Data from managed care plans may be less detailed than fee-for-service claims, potentially obscuring specific services.
- Clinic Caseload vs. Enrollees: Analyses often use entire clinic caseloads identified by NPIs, which might include individuals not directly enrolled in the PBHCI program. This can dilute the observed impact of the program but offers a broader view of clinic-level changes.
Despite these limitations, Medicaid claims data linked via NPIs provide invaluable insights into the real-world impact of integrated care programs on healthcare utilization, costs, and quality, offering a perspective beyond data collected solely within PBHCI clinics.
Impact of PBHCI Programs: Evidence from Research
The RAND Corporation’s study, utilizing Medicaid claims data and NPIs to identify PBHCI clinics, revealed mixed but informative results about the impact of integrated care.
Key Findings:
- Reduced Frequent ED/IP Utilization: PBHCI was associated with a reduction in frequent emergency department (ED) and inpatient (IP) service use, particularly for physical health conditions. This suggests that integrated care can effectively manage health needs in less intensive settings.
- Mixed Cost Impacts: PBHCI programs showed potential for cost savings or neutral cost effects, but the pathways to cost reduction varied across different cohorts and states. Some programs reduced total costs through decreased outpatient expenses, while others saw savings from reduced ED or inpatient costs. Importantly, no program significantly increased overall Medicaid costs.
- Limited Impact on Quality Measures: The study found less consistent positive impacts on standard quality of care measures (e.g., diabetes monitoring, cancer screenings). This suggests that while access to primary care might improve, achieving significant improvements in preventive service delivery requires further attention.

Implications and Future Directions
The findings suggest that Medicaid Integrated Care Programs, like those supported by PBHCI grants, hold promise for improving healthcare delivery for individuals with SMI and complex health needs. The use of NPIs and claims data is crucial for understanding their impact on a system-wide level.
Moving forward, key areas for development include:
- Enhancing Quality of Preventive Care: Strategies to improve the delivery and uptake of preventive services within integrated care settings are needed. This might involve more robust care coordination, patient education, and addressing barriers to accessing external medical providers.
- Understanding Cost Reduction Mechanisms: Further research should explore the diverse pathways through which integrated care can achieve cost savings to optimize program design and implementation.
- Targeting Frequent ED/IP Users: PBHCI models might be further refined to specifically target individuals with a history of high ED and inpatient utilization, potentially maximizing their impact on reducing costly care.
Conclusion
Medicaid Integrated Care Programs represent a significant shift towards a more holistic and effective approach to healthcare, particularly for vulnerable populations. The use of NPIs is instrumental in evaluating these programs and understanding their impact on healthcare systems. While evidence suggests positive effects on utilization and costs, ongoing efforts are crucial to optimize these programs and ensure they consistently deliver improved quality of care and better health outcomes for all individuals they serve. By continuing to leverage data, including NPI-linked claims data, and build upon the lessons learned from initiatives like PBHCI, we can advance the field of integrated healthcare and create a more person-centered and efficient healthcare system.
