AbstractThe Affordable Care Act of 2010 authorized the continued availability of Medicare Advantage Chronic Condition Special Needs Plans (C-SNPs). This case study examines the model of care used by the largest such plan, Care Improvement Plus, and compares utilization rates among its diabetes patients with those of other beneficiaries enrolled in fee-for-service Medicare in the same five states. This special-needs plan emphasizes direct contacts with patients to help identify gaps in care and promote primary and preventive health care. The comparative analysis indicates that people with diabetes in the special-needs plan-particularly nonwhite beneficiaries-had lower rates of hospitalization and readmission than their peers in fee-for-service Medicare. For example, risk-adjusted hospital days per enrollee among special-needs plan participants were 19 percent lower than for fee-for-service Medicare enrollees (27 percent lower for nonwhite enrollees). Risk-adjusted physician office visits were 7 percent higher among C-SNP enrollees than among comparable fee-for-service enrollees (26 percent higher for nonwhite enrollees). Although this study does not include a cost analysis, we believe that savings from reduced hospitalizations are likely to more than offset the additional costs of enhanced primary care programs. Our study suggests that the Centers for Medicare and Medicaid Services may be able to adapt methods used by the C-SNP program to improve care and outcomes for beneficiaries with a broad range of chronic diseases.
