Summary
Managed care organizations are shifting from local, single-product entities to national, diversified corporations. This transformation is driven by consumer and provider heterogeneity, leading to broader networks and services.
Area of Science:
- Health Services Research
- Healthcare Management
- Health Economics
Background:
- The managed care system is undergoing significant structural changes.
- The central organization, the health plan, is evolving from a single-product to a multiproduct, multimarket entity.
Purpose of the Study:
- To analyze the transformation of the central organization within the managed care system.
- To examine the drivers and implications of changes in health plan structures.
Main Methods:
- Analysis of vertical disintegration (shift from ownership to contractual linkages).
- Examination of horizontal integration (consolidation of various insurance carriers and networks).
- Assessment of market and consumer heterogeneity influencing organizational strategies.
Main Results:
- Health plans are increasingly diversifying into multiple networks, benefit products, distribution channels, and geographic regions.
- There is a trend towards consolidation, integrating indemnity carriers, Blue Cross plans, health maintenance organizations (HMOs), and specialty networks.
- Heterogeneity in consumer preferences and provider willingness to adopt structures sustains diversified health plans.
Conclusions:
- Diversification is reshaping health plans into national, full-service corporations.
- The future of health plans lies in broad diversification rather than local, single-product specialization.
- Understanding market heterogeneity is key to navigating the evolving managed care landscape.
