Why did I receive two EOBs from my insurance company for lab work?
Certain payors prefer that the separate companies performing laboratory services each bill for their own services, meaning the physicians bill for their services and the laboratory bills for its services.
When these services are performed and billed separately, patients may see two EOBs (Explanation of Benefits) from their insurance company, one for the “professional component” (reading the slide or other results) and one for the “technical component” (preparing the specimen or performing tests). If a co-payment is required from the patient, you will possibly receive two invoices, one from each company or organization. If you have any questions, please contact the billing office listed on the invoice you receive.
Why did it take so long to receive an invoice?
Typically, it takes 60 days or more for insurance companies to respond to CSI Laboratories’ claims. Sometimes the insurer’s response to CSI Laboratories is that more information is needed in order to process the claim. The billing cycle then restarts and may repeat itself several times.
CSI Laboratories attempts to collect our claims from insurance compaies without bothering the patient in the process. As a result, by the time the insurer calculates your financial responsibility and you receive an invoice from CSI Laboratories, it may be more than four or five months after the date of the visit to your physician.
I received an EOB from my insurance company. Does it require further action?
An Explanation of Benefits (EOB) is a notification from your insurance company after it has processed a claim. An EOB is not a bill. It is only an estimate of your financial responsibility. CSI Laboratories will review the initial determination from your insurance company and may take additional action that could result in a change to your financial responsibility listed on the EOB. The only time you should pay CSI Laboratories is if you receive an invoice from us.
Why did I receive an invoice from a pathology company?
If you or your insurance company received an invoice from CSI Laboratories, it is because we provided pathology lab services to your physician on your behalf. You may have heard that your specimen or biopsy was sent to the lab. CSI Laboratories has several locations across the country. Your specimen or biopsy was reviewed by a pathologist, which is a doctor who has specialization in the diagnosis of disease. At CSI Laboratories, all of the pathologists have specialization in their specific field of pathology.
What should I do with the invoice I received from CSI Laboratories?
Co-insurance, co-payments, and deductibles: Your invoice from CSI Laboratories usually pertains to a deductible or copayment according to the terms of your benefits with your insurer.
