Prometheus Laboratories
Reviews and Complaints

I used their lab service in 2016, and paid my bill in full. They then re-billed the issue in 2019 and sent the bills to a different insurance company, even though I am in AZ, under a new ticket number. They then sent the notice, 3 days before sending it to collections, after not issuing any communication for three years. This is clearly fraudulent and I had paid my bill in full. Why did they not contact me for three years and then immediately send it to collections? This is unacceptable.

Prometheus Laboratories informed me that a blood test they were scheduled to conduct for me would cost $75. I provided them with my health insurance details, but I made it clear to Prometheus Laboratories that my health insurance company would not cover the blood test I required. They assured me that the price would remain at $75. However, I recently received a bill today (4/8) from them amounting to $2500.00. Upon contacting them, a representative suggested there might be an issue with my insurance details, and upon review, we discovered they had recorded an incorrect member number. The representative mentioned they would re-submit the claim to my insurance, which is expected to be denied. I am baffled as to why I received this bill. It would have been more appropriate for them to contact me to verify my insurance information before proceeding.

I am having the exact same issue as the other complaints that I've read against this business. They do not answer their phone, they do not return messages and they do not answer emails as I've tried several times to connect with them over about 6 months now regarding a charge for lab work requested by my Doctor. They have sent me to collections on a $2500 bill that should be $75. I provided them with all of the necessary paperwork, it just seems as if they aren't doing anything except moving bills into collections.

I had a blood test done by Prometheus Biosciences on October 9. In January I received a bill for $2500 which said that Prometheus had submitted the claim to my insurance and the insurance had not responded. I called Prometheus and they asked for an Explanation of Benefits from my medical group and also said I would not have to pay more than $75. First I called my insurance, who said they would fax the explanation to Prometheus. I received another bill for the full amount so I called Prometheus again. They said that they had never gotten the Explanation. I then contacted the medical group who said that they had paid $750 towards the bill and they would send the Explanation. Prometheus called asking for the number of the medical group because they had gotten the explanation but could not find the payment. I called and left a message with this information. Today I got a final notice for $2500 before being sent to collections if I do not respond in 15 days. My account number is omitted.

This lab submitted my bill to the wrong insurance company therefore I received the full bill in the mail. I called the number on the website. They did not answer. Their answering machine says to leave a detailed message and they would call back. They never did. Two weeks later I got a "past due" bill. I called again, the same thing happened. I emailed every email listed on their website. No response. I called again, no response. This seems like a sham yet I am fearful my credit will be ruined. FL Blue will handle this bill, or try to, but they are clearly lying and hope to put someone in collections.

My husband had a test done through Prometheus Biosciences. Prometheus has been unsuccessful in contacting our insurance to process the claim. On the invoice sent to me from their lab, it indicates I need to follow up with my insurance to respond to their claim. Both myself and my insurance *** have not been able to get ahold of anyone at Prometheus, despite numerous and lengthy attempts. I would like to know what Prometheus suggests I do, as they are not reachable. Perhaps it would be better if they contacted our insurance regarding the claim directly as I dont feel sitting on hold in a queue with their billing department for over two hours is reasonable at this point. I am also sending an email with this quandary to all email contact options affiliated with Prometheus.

I just recently - in February - received a bill for services dated March for $2,500 from a company called Prometheus Biosciences. I have no idea what the bill is for (the date of service was nearly two years ago). The company not only put the wrong middle initial on the bill but also billed the wrong insurance company (if the charge is even appropriate in the first place). Because the date they're supposedly billing me for was two years ago, I've also switched insurance plans since then. I'm calling to try and resolve the situation and no one is answering.

My doctor sent bloodwork to Prometheus labs due to some IBS issues I was experiencing, and a year later, I received a bill for $656.77! I called them, and they informed me that my insurance company, Aetna, had not provided the necessary documentation and that I needed to contact them. After reaching out to Aetna and obtaining the required documents, I attempted to contact Prometheus for over a week but was unable to get through to anyone. Eventually, I resorted to printing the paperwork and mailing it to their P.O. Box in California. Despite this, I continue to receive bills and my attempts to call them are fruitless. Each time I'm placed on hold with the promise of speaking to a representative, I'm either disconnected or, after an hour's wait, informed of system issues. This has been going on for months. I've even tried reaching out through their website's 'contact' section, leaving several messages, yet no one has returned my calls. I'm concerned about my credit score being affected, but I shouldn't be responsible for this bill since I have insurance. I'm at a loss on how to resolve this situation and am considering the possibility of seeking legal assistance.
