How do I check eligibility and benefits for these members?

  • Online: Eligibility, benefits, claims, links to secure messaging, commonly used forms and remit information are all available through the Availity* Portal at For questions on access and registration, call Availity Client Services at 1-800-AVAILITY (800-282-4548). Availity Client Services is available Monday through Friday, 8:00 a.m. to 7:00 p.m. ET (excluding holidays) to answer your registration questions.
  • Phone: Call the Provider Service number on the back of the member’s ID card. You may also verify a member’s eligibility by calling the BlueCard Eligibility Line at 1‑800‑676‑BLUE (2583) and providing the member’s three-digit alpha prefix located on the ID card.


As new members enroll in Anthem’s Group Retiree Medicare Advantage plans, they will receive new ID cards. Additionally, existing members may receive new ID cards as a result of benefit changes. Please continue to check member ID cards to ensure you have the most up-to-date eligibility and benefit information.


Please note that we are experiencing a high volume of changes for an effective date of January 1, 2021, and some of the changes will affect member prefix, member ID or benefits. Because of this, we encourage providers to request a copy of the member’s ID card, particularly at the beginning of the year when members may have new ID cards.
