Key Stories
Wakely: Medicaid MCO margins flip to losses as enrollment drops
Wakely's February 2026 NAIC-based study of 170 Medicaid MCO filers shows underwriting margin swung from 2.4% in 2023 to -1.0% in 2024, a $2.8B loss. By 3Q2025 annualized, average membership fell 13% to 38.5M and MLR worsened to 91.2% on $287B of revenue. Wakely ties the reversal to post-April 2023 redeterminations, with 31% disenrolled, which pushed acuity and 2024 per-capita spending up 15.2%. With Public Law 119-21, the H.R.1 reconciliation act, expected to keep enrollment sliding, capitation adequacy will live or die on rate true-ups and risk corridors.
UnitedHealth loses former Optum CEO as it trims subsidiary disclosures
Heather Cianfrocco, an executive vice president and former Optum CEO, announced she is leaving UnitedHealth after a 24-year tenure. The exit thins the Optum leadership bench as the services arm remains central to UnitedHealth's earnings story. Separately, UnitedHealth's latest annual report lists only 10 subsidiaries, down from more than 3,100 previously disclosed, according to STAT. Less entity-level visibility plus exec churn raises the cost of segment math and can widen uncertainty on where margin and risk sit.
Vizient: Multi-chronic patients drive admissions, threaten hospital margins
Vizient claims analysis found 11% of people with multiple chronic conditions drive 52% of inpatient admissions and about one-third of outpatient visits. Vizient said this group is projected to increase, and its unfavorable payer mix could pressure health systems' finances. More beds and staff then become a cost bet: incremental volume can land in lower reimbursement while acuity raises labor and supply spend. Finance teams should stress-test margins with scenario mixes for multi-morbidity growth, not just utilization totals.
Significant Digit
Hospitals were the biggest marginal-dollar driver of recent national health spending growth, which is why price, coding intensity, and site-of-care are now budget items, not debate topics.
KFF estimates U.S. national health expenditures rose $692B from 2022 to 2024, and hospital care alone contributed $277B of that increase, or 40%. Hospitals also grew faster than total health spending over that window (20% vs 15%). If you are looking for trend relief, this is your reminder that hospital contracting and outpatient migration are where the money actually moves.
