Electronic Explanations of Review (e-EORs) are a non-negotiable requirement of workers’ comp electronic billing. Within 15 working days of receiving a provider’s e-bill, the claims administrator must — by California law — return the e-EOR. This allows billing software to automatically post payment details to the e-bill and closes the electronic loop on the transaction.
daisyBill closely monitors claims administrator compliance with e-EOR requirements, as they are crucial to our provider clients’ revenue management. Without e-EORs, billing software cannot automatically record payment information for e-bills, and providers are forced to waste practice time and resources updating their e-bills manually.
Below, see how our top 10 claims administrators by bill volume complied with sending electronic EORs (in the mandated X12 835 format) in 2022 so far.
Data from daisyBill shows exactly how often each of our top 10 claims administrators timely returned a compliant, valid X12 835 e-EOR.
All tables below reflect e-EOR data for e-bills submitted from January 1, 2022 to August 31, 2022 by daisyBill clients.

Most Compliant: Liberty Mutual
Liberty Mutual timely returned compliant e-EORs for 28,635 out of 34,150 e-bills, for a compliance rate of 84%. The sixth-largest recipient of daisyBill e-bills, Liberty Mutual gave the best performance overall by percentage.
However, Liberty Mutual has work to do. Compliance with legal requirements should be 100%; 83% is (barely) a grade B effort. Further below, the data show that to receive a grade of ‘A,’ Liberty Mutual must correct its missing e-EORs.
Least Compliant: ESIS, Inc.
In last place is Third-Party Administrator (TPA) ESIS, Inc., which returned timely, compliant e-EORs for only 14,339 e-bills out of 33,678 submitted — less than half, for a dismal e-EOR compliance rate of just 43%. Grade: F-
As mentioned above, within 15 working days of receipt of an e-bill, California regulations require claims administrators to send an e-EOR in response (14 calendar days to send the e-EOR for Second Review appeals). Below, daisyBill data shows how well (or not) claims administrators complied with e-EOR timeliness requirements.

Most Compliant: Liberty Mutual
Liberty Mutual takes the cake again, returning untimely e-EORs for only 1% of daisyBill providers’ e-bills. Good job, Liberty Mutual!
Least Compliant: Intercare Holdings Insurance, Inc.
Intercare was late returning e-EORs for 11,017 e-bills out of 31,302 submitted. That’s a non-compliance rate of 35%, showing that while Intercare eventually returns e-EORs (Intercare’s rate of missing e-EORs was only 5%), the TPA takes its sweet time.
Sometimes, the provider receives no e-EOR at all. This means either 1) the claims administrator did not pay the bill, or 2) the claims administrator sent a non-compliant paper EOR, forcing the provider to manually post the EOR data to their e-billing software. Either way: not acceptable.

Most Compliant: State Compensation Insurance Fund (SCIF)
SCIF is the second-largest recipient of daisyBill e-bills, having received 72,206 e-bills from our providers from January through August of this year. Of those, SCIF failed to return an e-EOR for 319. If SCIF repaired its untimely e-EORs (SCIF has blamed Anthem for its own non-compliance), SCIF would earn a solid A+ for e-EORs.
Least Complaint: ESIS, Inc.
Out of 33,678 e-bills submitted, ESIS failed to return an e-EOR for 10,976, or 33%. This is, by any reasonable standard of compliance, unacceptable. Having hounded ESIS across California to pay Medical-Legal bills, we shouldn’t be surprised to see the TPA disregard medical bill requirements. Any employer considering ESIS as a TPA would serve themselves well by reviewing this EOR data.
Sedgwick Claims Management Services is by far the most-daisyBilled claims administrator by bill volume; our providers sent the TPA almost 200,000 e-bills from January 1 to August 31. While Segwick didn’t earn the distinction of “least compliant” for any of the specific categories above, its overall non-compliance is a serious issue

Most distressingly, Sedgwick returned zero e-EORs whatsoever for 23% of the e-bills submitted by our providers. That’s the second-worst rate after ESIS — but Sedgwick is processing many, many more e-bills. By way of comparison:
The benefits of e-billing should not flow in only one direction. Anything less than 100% compliance with e-EOR requirements means that providers — and by extension, injured workers and employers — are being mistreated.
