Electronic Funds Transfers (EFT) Registration

This tool eliminates the need for paper registration, reduces administrative time and costs, and allows you to register with multiple payers at one time.

If you were previously registered to receive EFT only, you must register using EnrollHub to manage account changes.

Important Notice About Receiving EFT Payments

If you were previously enrolled with Beacon Health Options for EFT, you will need to re-enroll for EFT with UniCare if you haven't already done so. If you don't re-enroll, you will automatically receive payment via check.

How to Submit a Corrected Claim to Avoid Rejection


To prevent your corrected claim from getting rejected as a duplicate claim, ask your software vendor to do the following:

  • Populate the claim with the frequency type code of 7 (adjustment) in Loop 2300 (CLM5-3).
  • Populate the Original Reference Number (ICN/DCN in Loop 2300 with the UniCare claim number).

If you file your claims using free web-based transactions without a vendor, you should also follow the above steps when submitting corrected claims to avoid the claim getting rejected as a duplicate.

Trading partners can also purchase the full Technical Report Type 3 (TR3) guides from Washington Publishing Company.
