When researchers at the Johns Hopkins Bloomberg School of Public Health looked at the data, they discovered that the price different insurers pay for the same billed charges “can be three or more times different at the same hospital,” said Ge Bai, a professor of health care accounting who was among the researchers.
Samantha Smith of Harrisburg, Pennsylvania, went into the operating room for emergency removal of an ectopic pregnancy. “I’m grateful I didn’t die,” she said, but she was shocked to see that the outpatient surgery was billed to her insurer for about $100,000.
Jamie Estrada of Albuquerque, New Mexico, twice received injections of lidocaine in his upper spine to test if a permanent nerve ablation would treat his chronic neck pain. His pain vanished — until the numbing agent wore off about six hours later. The real zinger: His insurer was billed $28,000 for each 10-minute procedure.
Mark McCullick of Longmont, Colorado, was sent for a whole-body PET scan to find out whether his prostate cancer was back. The two-hour scan showed no evidence of cancer, but the $77,000 bill sent to the company that administered his insurance alarmed him.
Smith, Estrada, and McCullick’s cases are all “chargemaster” bills, calculated from the master price list that health providers place on services. Patients who have insurance don’t generally pay them. But they matter because they are often the starting point for the negotiated price the insurer agrees is reasonable to pay for the services. Patients are typically responsible for 10% to 20% of the negotiated price, their coinsurance — and when prices are this high, that can be a big number. What’s more, those negotiated rates are difficult for patients to access (until they get the bill) and seemingly arbitrary.
In the cases of Smith and Estrada, their insurers paid the majority without questions. Penn State’s Hershey Medical Center, which treated Smith, received $61,000, or 62% of what it charged. New Mexico Surgery Center Orthopaedics, which treated Estrada, received $46,000, or 82%.
McCullick’s insurer, on the other hand, said it would pay Intermountain Health just 28% of his $77,000 bill. Then came another curveball: The hospital, which said it had gotten preauthorization, discovered after the fact that his scan was not covered. So it billed McCullick the full chargemaster rate of $77,000 — or, it offered, he could pay the cash rate of $14,259.
