Third-Party Administrator Plans: Customer Service Inquiries

Use the Phone Numbers on Back of the Member Cards

Providers are incorrectly calling Highmark’s customer service for Third-Party Administrator (TPAs) plans, which is causing delayed responses for your patients and our members. 

Background

Using a shared services model, Highmark partners with TPAs to provide our insurance products to additional members. TPA plans have their own dedicated customer service numbers. 

Where is the phone number for a TPA plan?

Important phone numbers, including for customer service, are on the back of the member’s card.

How can you identify a TPA plan?

Front of the card:

• The member ID number will ALWAYS have a 3-character alpha prefix and a 2-character Client Assigned ID (CAID), followed by a 7-digit member number.
• Typically, the TPA logo will be in the bottom left corner.

Back of the card:

• The TPA website will usually be listed at the top right corner of the back of the card.
• The TPA customer service, pre-authorization and any other phone numbers that are relevant to the member will be listed.
