For workers’ comp electronic billing (e-billing) to work, it’s not enough to simply send the e-bills and hope for the best.

The best technology tracks every e-bill through the entire cycle—from submission to payment—and flags when a payer misses a deadline to respond.

Recently, daisyBill compliance technology raised an alarm when CorVel failed to send electronic acknowledgements confirming receipt of 154 e-bills from multiple providers.

Because our systems “noticed” the missing acknowledgements, our team immediately contacted CorVel, which acknowledged having failed to receive the (compliant and valid) e-bills and instructed daisyBill to resend them.

CorVel does not use an outside clearinghouse vendor to accept providers’ e-bills; daisyBill has a direct Electronic Data Interchange (EDI) connection with CorVel. In the last 365 days daisyBill has submitted over 145,000 e-bills directly to CorVel on behalf of our clients without any issues—but any claims administrator can stumble.

Despite the hiccup, daisyBill technology ensured that every missing e-bill was sent to CorVel for processing within a week of the clients’ first submissions.

Read below to determine if your practice needs to resubmit CorVel e-bills sent on July 1, 2025.

Ensuring e-Bill Delivery: Automatic Payment Cycle Tracking

Successful bill delivery is the first challenge of e-billing—which is why e-billing software must keep track of whether claims administrators timely acknowledge receiving each e-bill.

Under California’s Medical Billing and Payment Guide for workers’ comp, CorVel (or in most cases, the claims administrator’s clearinghouse) has one working day to send the provider a “999” electronic acknowledgement confirming receipt of an e-bill (the 999 is distinct from the “277” acknowledgement indicating whether the e-bill is accepted for processing).

Multiple daisyBill clients submitted e-bills to CorVel on July 1, 2025. But when CorVel missed the deadline for sending daisyBill the required 999 acknowledgment, daisyBill software kicked into action.

As the screenshot below shows, our systems generated a Compliance Alert for each of the 154 e-bills for which CorVel failed to send the 999 acknowledgement.

Our Compliance Team knew it was time to investigate further.

We contacted CorVel, which reported never having received the e-bills for reasons that remain unknown. CorVel asked us to resubmit the e-bills; we did, and CorVel issued the appropriate 999 (and subsequent 277) acknowledgements.

Automation Protects Your Practice

Keeping workers’ comp billing smooth and efficient requires automating as much administrative work as possible. Errors, glitches, and payer non-compliance are inevitable; what matters is that your billing software catches e-billing problems and addresses them proactively.

If the providers in this case were not daisyBill clients, the missing e-bills might have flown under the radar.

Using software designed for Medicare or group health rather than specifically for workers’ comp, submitting all workers’ comp e-bills through a single clearinghouse, or (worst of all) submitting bills on paper can lead to missing or egregiously late payments—and revenue management chaos.

Using technology to monitor every bill and payment allows practices to devote more time and resources to what matters most: treating injured workers without getting mired in administrative complexities.
