Insurance Update for Our Patients
We are aware of the status of Cigna and CommonSpirit-CHI Memorial and understand that many patients have questions.
Please rest assured that Diagnostic Pathology Services is not part of the CommonSpirit-CHI Memorial Organization. While our pathologists do work with CHI Memorial facilities, this status does not affect your insurance coverage on professional pathology diagnoses or the service you receive with our company.
If you have additional questions or this remains unclear to you, please feel free to call us at 423-629-7688 and we will be happy to talk you through the details.
