The Consequence Library · How records are made and graded
An automated review system flagged claims for denial and Cigna medical directors signed off on them in batches, reportedly denying over 300,000 requests across a two-month period at an average of about 1.2 seconds per claim, without opening individual patient files.
Evidence caveat. The denial volumes and per-claim timings derive from internal company documents obtained and reported by ProPublica, and from former-employee accounts. Cigna has disputed characterisations of the programme.
What happened
ProPublica reporting in March 2023 documented the PxDx system, which matched claims against a list of tests and procedures and produced denial recommendations that medical directors then approved in bulk. Internal documents and former-employee accounts described directors signing large batches at a rate that made individual clinical consideration impossible. The practice drew litigation and regulatory attention, and a court subsequently addressed whether the process satisfied the insurer's obligation to conduct a fair and reasonable investigation.
Where control failed
Physician sign-off remained part of the process. Reporting based on internal documents described processing volumes and average review times that raise questions about the amount of individual review applied to each recommendation. Cigna has disputed characterisations of the programme.
The authority question
The process formally assigned decision authority to physicians. The relevant question is whether the time, information and discretion available to those reviewers allowed that authority to be exercised substantively for individual claims.
What could be proven afterward
The evidence exists because journalists obtained internal documents and former employees spoke. The rate itself, the fact that made the review nominal, was derivable only from internal records the affected patients never had. A denied patient had no way to establish, from anything they were given, that their claim had been considered for about a second.
Control state, before and after
Before the consequence
Physician sign-off as the human control on automated denial recommendations. No measurement of review time or reviewer capacity to dissent.
After the consequence
Litigation and regulatory scrutiny; the process examined against the obligation to conduct a fair and reasonable investigation.
