This is satire… but it’s also exactly how the system works.
Insurers built a 1.2-second lookup table that denies claims faster than a doctor can read the patient’s name. No chart review. No clinical judgment.
Just automatic “no.”
That’s not oversight. That’s the business model.
Taxpayers fund Medicaid plans that use the same games. Doctors should decide care, not a spreadsheet.
I am the Senior Vice President of Claims Optimization at Cigna. I built PXDX.
PXDX stands for Procedure-to-Diagnosis. It is a list. It matches a billing code to a diagnosis code. If the procedure doesn't match an approved diagnosis on the list, the claim is denied. Automatically. In an average of 1.2 seconds.
1.2 seconds.
That's faster than a doctor can read the patient's name.
In two months last year, our medical directors denied over 300,000 claims through PXDX. One doctor denied 121,000 in that stretch. Her name is on every letter. She did not open a single patient file. She clicked a button that approved batches of fifty at a time.
That's oversight.
PXDX is not a complex algorithm. It is a lookup table. A procedure either matches a diagnosis or it doesn't. There is no clinical judgment. There is no context. There is no patient. There is a code, and the code says no.
That's the system.
Before we added autonomic nervous system testing to the PXDX list, we were paying 100% of those claims. After, we denied 17,800 a year. Saved $2.4 million annually. On one test.
That's a correction.
Patients can appeal. The appeal process takes 40 to 60 days. The denial took 1.2 seconds. We call this "access to recourse." Our own internal documents estimate that only 5% of patients will appeal. Of those, most give up after the second round of paperwork. We know this. We planned for it.
That's engagement.
I received the 2024 Cigna Catalyst Award for Operational Excellence. The plaque says "Transforming Member Outcomes Through Intelligent Automation." It's mounted in the lobby of our Bloomfield, Connecticut, office, next to the mission statement that puts patients first.
No one has asked me to take it down.
1.2 seconds per claim. A doctor's signature on a letter she never read. An appeal window designed around the statistical probability that you won't use it. A lookup table that has never met a patient and never will.
The system doesn't deny claims. It denies the premise that claims should be reviewed.
I am PXDX. I am the 1.2 seconds. I am the doctor's name at the bottom of a letter no doctor wrote.
The system works.
