Membership Verification Line

The Membership Verification Line allows you extended access hours to confirm HMSA membership and coverage quickly and easily 24 hours a day, seven days a week. All you need is a phone, your HMSA provider number or your National Provider Identifier (NPI), your patient’s HMSA member ID number and your patient’s birth month, day and year. Follow these simple instructions:

  1. Call 808-948-6244 on Oahu or 1-800-552-8507 from the Neighbor Islands.

  2. The system will ask if you have a 10 digit NPI number.

    You can use either a Type 1 (individual) or Type 2 (group) NPI.

    • If you say “Yes” you will be prompted to say your NPI number.
      • The system will repeat your entry for confirmation.
    • If you say “No” you will be prompted to say your HMSA provider number.
      • The system will repeat your entry for confirmation.
  3. You will be asked to say your patient’s subscriber ID number
    • First, delete the first three alphabetic characters (e.g., XLA, XLP) and the leading zeros from the member ID number.
    • The system will repeat your entry for confirmation.
    • Example: For member ID number XLAR000012345678, you will say “R12345678”.
  4. Say your patient’s birth date.
    • The system will repeat your entry for confirmation.

    • 1 for Medical
    • 2 for Drug
    • 3 for Vision

  7. Listen for the coverage verification message. If your patient is active, you will hear the following information:
    • HMO members: Coverage code, health center, and earliest continuous effective date.
    • PPO members: Coverage code and earliest continuous effective date.
    • If your patient’s coverage ended within the last year, the system will provide the cancellation date.
    • If your patient’s coverage ended more than a year ago the system will say the member does not have this type of coverage.
    • If your patient does not have a specific type of coverage (e.g. Dental) the system will provide this information.
    • If your patient is enrolled under a COBRA account, the system will provide this information.
  8. Finally, enter:
    • 1 to inquire about another type of coverage (e.q. drug, vision) for the same member.
    • 2 to verify coverage for a different member.
    • 9 to end your call.
