Highmark continues to enhance its online EDI application process to better support you. In order to streamline all EDI authorization requests, your application will be systematically validated against our provider and billing information for accuracy. If a problem is identified, you will have the opportunity to correct the information before submitting the request for processing.

To assist you with the EDI application process, please note:
  1. Only National Provider Identifier (NPI) numbers can be accepted.
  2. Only group billing numbers will be added to a Trading Partner. It is not necessary to add a rendering provider number to a Trading Partner.
  3. Only one provider number may be submitted per application.
  4. After submitting a form, you will be able to submit additional forms or exit the EDI application process.
Please select the action you would like to complete for a Provider.
