Frequently Asked Questions: BlueCard

How can I identify a BlueCard member?

All Blue Cross and Blue Shield members have membership cards with the Blue Cross and/or Blue Shield service marks. Members who participate in the BlueCard program have a member identification number beginning with a three-character prefix that identifies their home plan. Also, the ID card will have a suitcase logo displayed somewhere on the card. Simply ask the member for his or her ID card, look for the suitcase logo and verify that the ID number begins with three alpha or alpha-numeric characters.

How can I verify eligibility for out-of-area BlueCard members?

First, look for the three-character prefix at the beginning of the member’s Blue Cross and/or Blue Shield identification number. Once you have located the prefix, you can call BlueCard Eligibility at 1-800-676-BLUE (2583) or log on to the Hawaii Healthcare Information Network (HHIN+) to verify the member’s plan and benefits coverage.

Note: The automated telephone network is available until 2 p.m. Hawaii time when the Mainland is on daylight-saving time; 3 p.m. when on standard time.

Blue Exchange Availability on HHIN+:
