Member Migration on January 1, 2023Member Migration on January 1, 2023

On January 1, 2023, the final group of your Highmark Blue Shield of Northeastern New York patients will be moved onto Highmark’s system as we complete our phased integration.

These Highmark members are served by the following plans:
  • Medicare Advantage
  • Essential Plan
  • Individual markets
  • Remaining large groups and Administrative Services Only (ASO)

What This Means for You

For all your Highmark patients starting January 1, you will need to use NaviNet® for:
  • Checking eligibility and benefits
  • Submitting preauthorization requests
  • Checking claims status

If you do not have a NaviNet account by now, you will need to register by January 1. Please click here to set up your account. If you think you are already registered with NaviNet for other payers, you can check your registration status here.

Electronic claims for all your Highmark patients can still be submitted through ASK and paper claims should be submitted to:

PO Box 4208
Buffalo, NY 14240-0080

For all Highmark patients starting January 1, providers should follow Highmark’s pharmacy drug and medical policies and other guidelines outlined in the Highmark Provider Manual, which is available on the Provider Resource Center.
