Vertical Integration
A corporate structure in which a single entity owns multiple layers of the healthcare delivery chain — insurer, pharmacy benefit manager, pharmacy, and physician group — creating structural conflicts of interest that prioritize profit over clinical outcomes. The mechanism S.3822 is specifically designed to dismantle.
What It Is
In most industries, vertical integration is a neutral business strategy — a company buys its suppliers or distributors to capture more margin. In healthcare, it creates a specific structural problem: when the entity that decides whether to pay for your care also owns the pharmacy where you'd fill the prescription, the physicians who would treat you, and the PBM that determines which drugs your plan covers — every denial is also, simultaneously, a revenue event.
The insurer profits from denying the claim. The PBM profits from the formulary position. The owned physician group captures the visit if you try a different route. The owned pharmacy captures the dispensing fee. The patient pays out of pocket for all of it.
The Documented Example — CVS Health
CVS Health simultaneously owns: Aetna (insurance), CVS Pharmacy (retail pharmacy chain), and CVS Caremark (one of the three dominant PBMs in the United States). Rep. Alexandria Ocasio-Cortez put CVS CEO David Joyner on record about this structure at the January 22, 2026 House Health Subcommittee hearing.
"You own the insurance company. You own the pharmacy. You own the pharmacy benefit manager."

The Physician Group Example — Cardinal Health & GI Alliance
In 2021, Cardinal Health — a Fortune 500 pharmaceutical distributor — acquired a majority stake in GI Alliance, the nation's largest gastroenterology physician group. This is vertical integration into the physician layer: the company that distributes the drugs now also owns the physicians who prescribe them. The FTC has documented this pattern across multiple specialty areas.
Why It Matters for Reform
S.3822 — the Break Up Big Medicine Act (Warren + Hawley) — targets vertical integration directly. It would require entities that own both insurance operations and healthcare delivery assets to divest. The cross-partisan support for this bill reflects a structural argument that transcends ideology: you cannot have a functioning healthcare market when the same company decides coverage, fills prescriptions, employs the physicians, and captures the spread on every transaction.
Rep. Dunn's floor statement — that prior authorization is the practice of medicine — becomes structurally coherent only in the context of vertical integration. The insurance company is not merely denying a claim. It is overriding a physician's clinical decision while owning the entire alternative pathway the patient would use instead.
