Seven Reasons for Rejected e-Bills

Last update
February 28, 2024

Per the California Division of Workers’ Compensation (DWC), a claims administrator must review original electronic bills and return an acknowledgement to the provider within two working days of receipt.[1]  This acknowledgement, or 277, alerts the provider whether the bill was accepted or rejected. A rejected 277 means the claims administrator will not process the bill.

Compliant rejections benefit everyone. They help the claims administrator receive clean, compliant bills and they significantly shorten the revenue cycle by alerting providers to bill errors. Instead of waiting for weeks as a bill crawls through the postal service, resubmission of corrected electronic bills is as simple as one click of the mouse.

The DWC lists seven reasons why a claims administrator may reject a workers’ compensation e-bill. We’ll take them in order.

1. Invalid Form or Format

A provider’s electronic billing agent, or EDI agent, is responsible for converting the information that normally populates a paper billing form into an electronic file known as an 837. Claims administrators can reject electronic bills that are sent in the wrong electronic format.

2. Missing Information

This is one of the most straightforward rejections. Claims administrators reject electronic bills if the provider fails to provide their EDI agent with required patient or treatment information.

3. Invalid Data

Claims administrators can reject bills when the information transmitted via the 837 is not valid. Typographical errors or data discrepancies are often to blame for this rejection. Examples could include the use of invalid diagnosis or CPT codes, or when a biller accidentally switches the date of service and date of injury.

4. Missing Attachments

The bill submitter has the option to send the required supporting documentation (275 file) via fax or email. In such cases, a claims administrator will change the bill status to “pending” for up to five days while they wait for any required documentation that is sent separately from the bill itself. If proper documentation is not received in that time, the claims administrator may reject the bill.

5. Missing Required Documents

In addition to the 837 billing file, every compliant electronic bill for workers’ comp must include a PDF of the required supporting documentation, such as the PR-2 or DLSR form. These required documents accompany the electronic bill in a separate 275 file. If supporting documentation required by a particular CPT code is missing, the bill will be rejected.

6. Injured Workers’ Claim of Injury is Denied

This rejection occurs when the claims administrator denies liability for the injury.

7. No Coverage by the Claims Administrator

If the claims administrator cannot find or match the claim number of an electronic bill to a claim in their system, the bill may be rejected. The claims administrator may place the bill in “pending” status for up to five days while they attempt to match the billed claim information with the claims administrator’s claim information. For this rejection, most likely the bill was submitted to the wrong claims administrator.

daisyBill Solution

daisyBill scrubs bills prior to submission to prevent a biller from submitting any bill that is incomplete or non-compliant. Sometimes, however, claims administrators incorrectly reject compliant bills. In cases like this, daisyBill follows up with the claims administrator via fax to ensure that the bill is received.
