Emergency rooms

You can do every responsible thing — check the hospital’s network, drive to the right ER — and still be treated by a physician who does not work for that hospital. For years the country’s two dominant emergency-staffing companies, Envision (KKR) and TeamHealth (Blackstone), supplied those doctors. When the physician group was out of network, patients got a second bill the hospital’s sign had not advertised. That arbitrage helped push Congress to pass the No Surprises Act. The debt from the buyouts then helped push the companies into crisis. Ground ambulances, a close cousin, were mostly left out of the law.

Active in

The No Surprises Act is a law written to stop a business model: the out-of-network doctor inside the in-network emergency room.

The statute’s target, in plain language

Findings

The ban
January 2022

The No Surprises Act largely stops surprise bills for emergency care and for certain out-of-network clinicians at in-network facilities. Patients are meant to pay in-network cost sharing. Disputes move to an arbitration process between insurer and physician group.

The sponsors
KKR and Blackstone

KKR took Envision private in 2018. Blackstone bought TeamHealth in 2017. Between them they staffed a huge share of American emergency departments. The brand on the hospital door was often unrelated.

The leftover hole
Ambulances

Most ground ambulance rides were carved out of the surprise-billing ban. A ride you cannot refuse can still be billed by a company you did not choose, sometimes owned through the same financial food chain.

The playbook, in this industry

  1. 01

    Staff the ER without owning the hospital

    Hospitals outsource emergency physicians, anesthesiologists, and hospitalists. The staffing firm hires the doctors, captures the professional fee, and can stay out of network even when the facility is in network.

  2. 02

    Price the captivity

    An emergency patient does not negotiate. Out-of-network balance bills turned that fact into yield. Insurers sometimes paid the inflated charge to avoid member revolt; sometimes the member was left holding it.

  3. 03

    Lever the roll-up

    Buying hundreds of physician practices required debt. The debt assumed the out-of-network strategy, or something equally rich, would continue.

  4. 04

    When the law changes, the debt remains

    The No Surprises Act damaged the yield. Envision filed for bankruptcy in 2023. The public got a partial protection and a lesson: the company can fail after the bills have already been sent.

Incidents

  1. 2017

    Blackstone buys TeamHealth

    One of the largest physician-staffing companies in the country moves under a private-equity sponsor. Emergency medicine is now a portfolio company at national scale.

  2. 2018

    KKR takes Envision private

    Envision, parent of EmCare, is bought in a debt-heavy deal. The company’s emergency physicians are, for millions of patients, the doctor they did not choose.

  3. 2020

    Congress passes the No Surprises Act

    After years of patient stories and research on out-of-network prevalence at PE-staffed ERs, a rare bipartisan law draws a line. It takes effect in 2022.

  4. 2023

    Envision’s bankruptcy

    KKR’s staffing bet files for Chapter 11, loaded with billions in debt. The doctors are still needed. The capital structure is not.

Case files

Emergency departments nationwide

The in-network hospital, the out-of-network doctor

This case has no single campus because the design was national. A patient is taken, or drives, to a hospital their insurance covers. The emergency physicians are employed by a staffing company whose contract with insurers is a separate fight, or no contract at all. Before 2022 the second bill could dwarf the first. Researchers and journalists tied the highest out-of-network rates to the private-equity staffing giants more than to independent physician groups. The No Surprises Act transfers much of that fight off the kitchen table and into arbitration. It does not turn the clock back on a decade of bills, and it does not make the ER less corporate.

The public bill. Years of balance bills for care people already thought was covered. A law that exists because the bills became politically unbearable.

Envision after the yield broke

Envision’s bankruptcy is the financial end of a patient-facing strategy. Buy practices, staff hospitals, bill aggressively, service a buyout’s debt. When Congress constrains surprise billing and insurers harden, the debt does not shrink to match. Doctors who thought they had sold to a stable employer meet a Chapter 11. Patients meet a new owner of the same contract. The public-facing brand remains the hospital’s. That mismatch — whose name is on the door, whose invoice arrives — is the whole file.

The public bill. A partial consumer protection, a bankrupt giant, and ERs still staffed by firms patients cannot hire or fire.

What the public lost

Cost

  • Surprise bills that treated emergency care as an out-of-network product
  • Higher negotiated rates once insurers gave in, which land in premiums for everyone
  • Ambulance bills still largely outside the 2022 ban

Access

  • No practical ability to choose your emergency physician
  • Hospitals dependent on outside groups for the most time-sensitive medicine
  • Staffing instability when the financial owner hits a wall, as Envision did

The owners’ argument

Staffing companies argue that hospitals could not recruit night-shift emergency physicians on their own, that out-of-network rates reflected insurer underpayment, and that the No Surprises Act’s arbitration has squeezed physician pay and accelerated consolidation with insurers. Recruitment in rural ERs is genuinely hard. A hard labor market does not require a surprise bill, and it does not require the recruiter to be a leveraged national platform.
