As of Jan. 1, the migration from NaviNet to the Availity Essentials portal for Geisinger Health Plan is complete. Since the transition, several new enhancements will streamline provider workflows and make it easier to access needed information, with further improvements planned throughout 2026. Here’s an overview of the newest functions in Availity, along with some best practices to help you get the most out of the portal.

  • Member ID cards – You can now generate electronic ID cards by searching for a member’s information through Eligibility and Benefits under the Patient Registration section. Once you’ve completed the required fields, a blue Member Card button will appear, allowing you to view or print the card.
  • Claim attachmentsClaim attachments are now available for currently keyed‑in claims through the Availity Essentials portal. This new functionality is especially helpful for providers who typically submit Geisinger Health Plan claims on paper — such as when billing with modifiers 25 or 59 and medical records are required for review, or when submitting GHP as secondary and primary EOPs must be included. This enhanced feature offers a convenient alternative to printing and mailing paper claims. Have questions or need support using the new attachment option? We’re happy to help. Or you can call Availity at 800-282-4548.
  • If you’re an Availity-registered provider, you can access training on key features related to Coordination of Benefits (COB) claims and attachments for professional claims through this link:  Availity Recorded Webinar.

Best practices for submitting keyed-in claims and attachments

  • For professional claim submissions, be sure the referring provider, rendering provider, service facility location and supervising provider information are entered under the rendering provider section.
  • For facility claims, use the Attending Provider Information dropdown to add rendering, referring and/or operating providers.
  • For professional and facility claims, always add the taxonomy under the specialty code section.
  • When submitting a claim online, treat the digital form exactly as you would a paper CMS-1500 or UB-04 form. All required fields must be completed in the online claim system in the same manner you would normally fill out and submit a standard claim form. Make sure you enter all diagnosis codes, procedure codes, revenue codes and bill types accurately.
  • Add as many diagnosis codes as are relevant.
