After a college student finally found a treatment that worked, the insurance giant decided it wouldn’t pay for the costly drugs. His fight to get coverage exposed the insurer’s hidden procedures for rejecting claims.

In May 2021, a nurse at UnitedHealthcare called a colleague to share some welcome news about a problem the two had been grappling with for weeks.

United provided the health insurance plan for students at Penn State University. It was a large and potentially lucrative account: lots of young, healthy students paying premiums in, not too many huge medical reimbursements going out.
But one student was costing United a lot of money. Christopher McNaughton suffered from a crippling case of ulcerative colitis — an ailment that caused him to develop severe arthritis, debilitating diarrhea, numbing fatigue and life-threatening blood clots. His medical bills were running nearly $2 million a year.
United had flagged McNaughton’s case as a “high dollar account,” and the company was reviewing whether it needed to keep paying for the expensive cocktail of drugs crafted by a Mayo Clinic specialist that had brought McNaughton’s disease under control after he’d been through years of misery.
