Executive Summary

Medicare risk is being repriced from both ends: insurers are shrinking exposure while regulators and operators tighten the machinery that determines payment, access, and fraud leakage.

Medicare Advantage contraction and access pressure are now the day’s dominant VBC signal: Humana and Centene are reducing Medicare Advantage footprints, with Centene’s expected cancellations potentially moving about 340,300 members to other plans, according to Wakely. Centene will cut some Medicare Advantage plans and exit three states, Modern Healthcare reports, while SCAN is making a contrarian Medicare Advantage bet as larger insurers pull back, Becker's Payer reports. Trust frictions are also surfacing at the point of care, with Medicare Advantage members losing confidence in their plans and physicians absorbing the fallout, Medical Economics reports.

Payment integrity, risk adjustment, and Medicaid financing are converging into a tougher operating regime: supplemental ACA claims increased average Plan Liability Risk Scores by 7.3%, making them a material lever for risk adjustment accuracy, financial performance, and RADV readiness, according to Wakely. Medicaid provider-tax rules are shifting under the 2025 reconciliation law and implementing regulations, with state financing strategies in the crosshairs, KFF reports. Durable medical equipment fraud remains a national Medicare vulnerability, HHS OIG reports, while AI-enabled prior authorization is becoming a revenue-cycle battleground as R1 moves to acquire Humata to automate claims processing and preapprovals, Healthcare Dive reports.

VBC delivery infrastructure is still consolidating despite the payment squeeze: seven Kansas rural hospitals formed a network to preserve independence and advance value-based care, American Hospital Association reports. Cityblock is acquiring Homeward Health and raising new capital, signaling continued investor appetite for scaled complex-care and rural-health platforms, Modern Healthcare reports.
