RESUMEN
Children with medical complexity (CMC) are a small but growing population representing <1% of all children while accounting for >30% of childhood health care expenditure. Complex care is a relatively new discipline that has emerged with goals of improving CMC care, optimizing CMC family function, and reducing health care costs. The provision of care coordination services is a major function of most complex care programs. Unfortunately, most complex care programs struggle to achieve financial sustainability in a predominately fee-for-service environment. The article describes how 2 programs in Wisconsin worked with their state Medicaid payer through a Centers for Medicare and Medicaid Services Health Care Innovation Award to develop a sustainable complex care payment model, and the value the payment model is currently bringing to stakeholders. Key elements of the process included: Developing a relationship between payer and clinicians that allowed for an understanding of each's viewpoint, use of an accepted clinical service model, and an effort to measure cost of care for the service provided supported by time-study methodology.
