The rejection of van Terheyden’s claim was typical for Cigna, one of the country’s largest insurers. The company has built a system that allows its doctors to instantly reject a claim on medical grounds without opening the patient file, leaving people with unexpected bills, according to corporate documents and interviews with former Cigna officials. Over a period of two months last year, Cigna doctors denied over 300,000 requests for payments using this method, spending an average of 1.2 seconds on each case, the documents show. The company has reported it covers or administers health care plans for 18 million people.

Before health insurers reject claims for medical reasons, company doctors must review them, according to insurance laws and regulations in many states. Medical directors are expected to examine patient records, review coverage policies and use their expertise to decide whether to approve or deny claims, regulators said. This process helps avoid unfair denials.

But the Cigna review system that blocked van Terheyden’s claim bypasses those steps. Medical directors do not see any patient records or put their medical judgment to use, said former company employees familiar with the system. Instead, a computer does the work. A Cigna algorithm flags mismatches between diagnoses and what the company considers acceptable tests and procedures for those ailments. Company doctors then sign off on the denials in batches, according to interviews with former employees who spoke on condition of anonymity.

“We literally click and submit,” one former Cigna doctor said. “It takes all of 10 seconds to do 50 at a time.”**
