In the United States, healthcare is big business, and one company has spent years on top.
UnitedHealth is really a healthcare giant.
That's my colleague, Anna Wildey-Matthews.
They have about $400 billion in annual revenue.
They own the biggest U.S. health insurer, which is called UnitedHealthcare.
But they're also one of the biggest providers of healthcare.
They own a sprawling network of doctor groups.
They own a large pharmacy benefit manager.
And they own a bunch of just sort of data and technology units,
pretty much any corner of the U.S. healthcare industry that you can think of.
UnitedHealth probably has some kind of element of it.
Ana and another colleague, Chris Weaver, have been reporting on UnitedHealth.
And over the last year and a half,
they've seen the company experience an onslaught of trouble and setbacks.
UnitedHealth groups had one of the most challenging years that any business could possibly imagine.
They're facing multiple investigations by the Department of Justice.
The Justice Department is investigating UnitedHealthcare's billing practices for Medicare.
They had a huge hack that crippled portions of the U.S. health system.
A cyber hack on the nation's largest healthcare platform,
UnitedHealth Group, continues to cripple critical services.
