# UnitedHealth Group The largest healthcare company in the United States ($447.6 billion revenue in FY2025) and the fullest expression of vertical integration in American medicine: UnitedHealthcare (the largest private insurer and largest Medicare Advantage player), Optum (physician groups, data analytics, banking), and OptumRx (one of the Big Three [[Pharmacy Benefit Managers]]). For this KB it is the central exhibit in the *insurer* wing of health-industry power — and, since December 2024, the company at the center of the most explosive health-populism story in modern American politics. ## The Empire and Its Logic UnitedHealth's model is owning every node: it insures the patient, employs or contracts the doctor, manages the drug benefit, dispenses through its pharmacies, and analyzes the claims data. Medicare Advantage is the profit engine — and the legal exposure. The [[Department of Justice]] has open **criminal and civil investigations** into whether UnitedHealth inflated patient diagnoses ("upcoding") to extract higher [[CMS]] reimbursements — the core allegation of the MA era, aimed at its largest practitioner. ## The Crisis Years (2024–2026) The [[UnitedHealthcare CEO Shooting]] — the December 2024 murder of insurance-division CEO Brian Thompson — detonated public rage at claim denials that the company never contained. What followed was a corporate unraveling: CEO Andrew Witty resigned abruptly in May 2025 with longtime former CEO Stephen Hemsley returning to the job, the stock collapsed roughly 55% from its highs, and the company guided to a rare revenue decline for 2026 while shedding over 3 million Medicare Advantage members in a "financial reset." The [[CMS]] rate-setting politics are worth tracking closely given who runs CMS: the January 2026 proposal of an effectively flat 0.09% MA rate update was followed in April by a final **2.48% increase (~$13 billion)** — a swing decided inside [[Mehmet Oz]]'s agency while DOJ investigates the industry's biggest player for gaming the same program's risk scores. ## Why It Matters Here UnitedHealth marks the boundary of the [[Big Pharma]] cluster's frame: drug-pricing populism and insurer populism are distinct currents, and the second proved more combustible. The company is also the test of whether the administration's health-industry posture is adversarial or transactional — MA rate generosity and stalled investigations would tell one story; indictments would tell another. ## Connections - [[UnitedHealthcare CEO Shooting]] — The detonation point - [[Pharmacy Benefit Managers]] — OptumRx and the Big Three - [[CMS]] / [[Mehmet Oz]] — Rate-setter and investigator-adjacent regulator - [[Department of Justice]] — Open criminal/civil MA probes - [[CVS Health]] / [[Cigna]] — Fellow vertically integrated conglomerates
