Care1st Health Plan Arizona

Filing a claim

Please be sure to verify eligibility prior to submitting a claim. Utilize the member ID card to submit the accurate member name, date of birth and ID number.

Electronic Data Interchange (EDI)

We strongly encourage you to submit your claims electronically!

Advantages include:

  • Decreased submission costs (printing, handling, mailing, etc.)
  • Faster processing and reimbursement
  • Allows for documentation of timely filing
  • Data submission accuracy (eliminates keystroke errors)

EDI submission is available for all claims (including those with primary insurance coverage). Note: When a member’s primary insurance is WellCare Liberty (FKA ONECare) and their secondary insurance is Care1st, our system automatically coordinates processing for these services and no secondary submission is required for all services other than Home Health Care, Durable Medical Equipment, MSIC/IC, or FQHC/RHC services. For these secondary exceptions a secondary red and white paper claim is required with a copy of the primary remittance advised attached

Medical records can be submitted electronically via secure FTP. Please contact our EDI team at to set this up.

Exception during the Covid-19 emergency: In addition to the Secure FTP option above, medical records with 50 pages or less may also be submitted electronically in the following format:

  • SECURE email to SM_AZ_ClaimsDataEntry@Care1st
    • Subject line: Care1st Claim Number (Example: 001234567)
    • Body of email: Provider Tax Id, Member ID, Date of Service
    • Attachment: medical records
