Cigna’s review system was developed more than a decade ago by a former pediatrician.
After leaving his practice, Dr. Alan Muney spent the next several decades advising insurers and private equity firms on how to wring savings out of health plans.
In 2010, Muney was managing health insurance for companies owned by Blackstone, the private equity firm, when Cigna tapped him to help spot savings in its operation, he said.
Insurers have wide authority to reject claims for care, but processing those denials can cost a few hundred dollars each, former executives said. Typically, claims are entered into the insurance system, screened by a nurse and reviewed by a medical director.
For lower-dollar claims, it was cheaper for Cigna to simply pay the bill, Muney said.
“They don’t want to spend money to review a whole bunch of stuff that costs more to review than it does to just pay for it,” Muney said.
Muney and his team had solved the problem once before. At UnitedHealthcare, where Muney was an executive, he said his group built a similar system to let its doctors quickly deny claims in bulk.
In response to questions, UnitedHealthcare said it uses technology that allows it to make “fast, efficient and streamlined coverage decisions based on members benefit plans and clinical criteria in compliance with state and federal laws.” The company did not directly address whether it uses a system similar to Cigna.
At Cigna, Muney and his team created a list of tests and procedures approved for use with certain illnesses. The system would automatically turn down payment for a treatment that didn’t match one of the conditions on the list. Denials were then sent to medical directors, who would reject these claims with no review of the patient file.
Cigna eventually designated the list “PXDX” — corporate shorthand for procedure-to-diagnosis. The list saved money in two ways. It allowed Cigna to begin turning down claims that it had once paid. And it made it cheaper to turn down claims, because the company’s doctors never had to open a file or conduct any in-depth review. They simply denied the claims in bulk with an electronic signature.
“The PXDX stuff is not reviewed by a doc or nurse or anything like that,” Muney said.
The review system was designed to prevent claims for care that Cigna considered unneeded or even harmful to the patient, Muney said. The policy simply allowed Cigna to cheaply identify claims that it had a right to deny.
“That adds administrative expense to medicine,” he said. “It’s not efficient.”
But two former Cigna doctors, who did not want to be identified by name for fear of breaking confidentiality agreements with Cigna, said the system was unfair to patients. They said the claims automatically routed for denial lacked such basic information as race and gender.
“It was very frustrating,” one doctor said.
Some state regulators questioned Cigna’s PXDX system.
In Maryland, where van Terheyden lives, state insurance officials said the PXDX system as described by a reporter raises “some red flags.”
The state’s law regulating group health plans purchased by employers requires that insurance company doctors be objective and flexible when they sit down to evaluate each case.
If medical directors are “truly rubber-stamping the output of the matching software without any additional review, it would be difficult for the medical director to comply with these requirements,” the Maryland Insurance Administration wrote in response to questions.
Medicare and Medicaid have a system that automatically prevents improper payment of claims that are wrongly coded. It does not reject payment on medical grounds.
Within the world of private insurance, Muney is certain that the PXDX formula has boosted the corporate bottom line. “It has undoubtedly saved billions of dollars,” he said.
Insurers benefit from the savings, but everyone stands to gain when health care costs are lowered and unneeded care is denied, he said.
Cigna carefully tracks how many patient claims its medical directors handle each month. Twelve times a year, medical directors receive a scorecard in the form of a spreadsheet that shows just how fast they have cleared PXDX cases.
Dopke, the doctor who turned down van Terheyden, rejected 121,000 claims in the first two months of 2022, according to the scorecard.
Dr. Richard Capek, another Cigna medical director, handled more than 80,000 instant denials in the same time span, the spreadsheet showed.
Dr. Paul Rossi has been a medical director at Cigna for over 30 years. Early last year, the physician denied more than 63,000 PXDX claims in two months.
Rossi, Dopke and Capek did not respond to attempts to contact them.
Howrigon, the former Cigna executive, said that although he was not involved in developing PXDX, he can understand the economics behind it.
“Put yourself in the shoes of the insurer,” Howrigon said. “Why not just deny them all and see which ones come back on appeal? From a cost perspective, it makes sense.”
Cigna knows that many patients will pay such bills rather than deal with the hassle of appealing a rejection, according to Howrigon and other former employees of the company. The PXDX list is focused on tests and treatments that typically cost a few hundred dollars each, said former Cigna employees.
“Insurers are very good at knowing when they can deny a claim and patients will grumble but still write a check,” Howrigon said.
Muney and other former Cigna executives emphasized that the PXDX system does leave room for the patient and their doctor to appeal a medical director’s decision to deny a claim.
But Cigna does not expect many appeals. In one corporate document, Cigna estimated that only 5% of people would appeal a denial resulting from a PXDX review.
