Benefits like faster payments and easier appeals are the obvious reasons to bill electronically (e-bill) for workers’ comp treatment.

…but they’re not the only reasons.

One of the biggest complaints we hear from non-client providers is the number of bills payers claim are “lost” or “not on file,” requiring practice staff to constantly resubmit duplicate bills (effectively doubling the administrative burden for each affected bill).

2025 daisyData show that our e-billing software all but eliminates this “missing” workers’ comp bill excuse. In 2025, daisyBill clients submitted 3.3 million e-bills, of which just 2% were duplicate submissions.

When a provider submits a workers’ comp e-bill, the payer must respond with an electronic receipt, timestamping and verifying exactly when the payer received the e-bill and making it impossible to incorrectly claim non-receipt. As a result, e-bills rarely require a duplicate resubmission.

Other bill delivery methods have drastically higher resubmission rates; daisyData from our clients show that in 2025:

• Bills sent via fax or email (6%) were nearly five times more likely to require duplicate resubmission
• The tiny percentage (0.5%) of bills delivered through the mail were nearly seven times more likely to require resubmission

The takeaway: In addition to being the fastest, e-billing is the most reliable billing method. See our 2025 stats below.

2025 daisyBill Duplicate Bill Submission Data

In 2025, daisyBill providers submitted over 3.5 million workers’ comp bills to 779 claims administrators and networks. The vast majority (almost 94%) were transmitted as e-bills, with a small minority sent via fax, email, or snail mail.

The data below show that only 2% of our clients’ e-bills were duplicates of an original bill, significantly less than any other delivery method.

These low duplicate rates are the result of our proprietary e-billing network, which delivers e-bills directly to the specific clearinghouse each payer uses to accept and manage workers’ comp e-bills (Jopari, Data Dimensions, Carisk, and P2P), while delivering e-bills directly to payers that do not use a clearinghouse (CorVel and the US Department of Labor).

daisyData: Claims Administrator and Network Duplicate Bills

daisyBill’s Claims Administrator and Network Directory publicly documents the number of duplicate bills our clients send to each claims administrator (aka payer) and network in the preceding 365 days.

Below is a screenshot of this data from today, 1/12/2026, for the top 10 claims administrators (as measured by the volume of bills daisyBill clients sent from 1/12/2025 to 1/12/2026).

• Surprising absolutely no one, Sedgwick had the highest duplicate submission rate of our top 10 at 3%. It’s no coincidence that the Directory also gives Sedgwick a “Grade” of ‘D’ for its Electronic Data Interchange performance.
  
  As always, Sedgwick’s position as the largest workers’ comp Third-Party Administrator in the nation means that its failures have an outsized impact on providers and employers.
  
  
• Once again, California’s State Compensation Insurance Fund is the only payer in the bunch to maintain a statistical 0% duplicate e-bill rate, yet another sign that this insurer’s leadership and tech proficiency are a model for other payers.

• Travelers significantly improved its performance from this time last year, reducing its duplicate rate from 5% at the beginning of 2025 to just 1% today. Kudos, now get it down to 0%!

The numbers show undeniably that workers' comp e-billing makes billing and revenue management drastically easier for practices. When payers make the choices necessary to perform strongly on their end, the result is a smoother, better system for all stakeholders.
