Due to our merger with Drexel University, several of the insurance companies are still updating their systems. In some cases, patients may be notified that TEI/PEI is not in their network. This is inaccurate. The clinical facilities changed their Tax ID numbers to the Drexel University Tax ID, but kept their same NPI numbers and credentialed staff. If you get this message, please contact your insurance company's customer service to verify that TEI/PEI is still in their network.
