Managed Care's Margin Machine Breaks
Managed-care earnings were built on predictable utilization, aggressive prior authorization and expanding vertically integrated service businesses. Higher medical use, coding scrutiny, Medicare Advantage rate pressure and political attention on claim denials are making those margins less dependable. Hospitals, rehabilitation providers and medical-device companies benefit when more approved procedures and patient volumes move through the healthcare system. Insurers and risk-bearing primary-care platforms face the opposite combination of higher claims, weaker reimbursement and reduced freedom to manage utilization.
