When will my insurance company pay Primex Clinical Laboratories’ bill?
Responses from insurance companies vary greatly. However, it normally takes a minimum of 6-8 weeks for Primex Clinical Laboratories to receive payment or denial information. Patients usually receive their explanation of benefits from the carrier several weeks before Primex Clinical Laboratories.

Still haven’t heard from them…

Why does my Explanation of Benefits (EOB) have different information than you show on your bill?
Primex Clinical Laboratories tries to communicate on the patient invoice the exact message sent to us by the carrier. However, sometimes the patient receives different information.

If this is the case…

Can you explain the information my insurance company sent to me regarding my benefits?
Primex Clinical Laboratories’ staff cannot answer questions about your specific policy and its provisions.

For the best results.
