Provider Changes

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 NPIs will be added to a Trading Partner.
  3. Do not request the addition of rendering provider numbers or Tax IDs to a Trading Partner.
  4. If ERA is requested, you must provide a valid contact within the provider’s office who is authorized to provide approval for any ERA changes.

Please select the action you would like to complete for a Provider.
