Apex is an E-Claims clearinghouse. Contact Apex for additional required steps when sending claims electronically using Apex. Apex website: http://www.apexedi.com

If claims are sent as a batch to Apex, preauthorizations and claims must be sent separately (Send Claims). If sent together, Apex will merge the data and reject the preauthorizations for having a date of service.
