Gallagher Bassett CALIFORNIA DATA - EDI COMPLIANCE

Since October 2012, California law has mandated that claims administrators accept electronic medical bills (e-bills) and adhere to specific timeframes established by the Division of Workers’ Compensation (DWC) Medical Billing and Payment Guide. These timeframes govern the following Electronic Data Interchange (EDI) transactions:

  • 837 (e-bill) Receipt: The provider's initial submission of the electronic medical bill and subsequent Second Review appeals.

  • 277 Acknowledgement (ACK) Receipt: An electronic confirmation from the claims administrator indicating that the e-bill has been received and whether it has been accepted or rejected.​

  • 835 Explanation of Review (EOR) Receipt: A detailed electronic response from the claims administrator outlining the adjudication results of the e-bill, including payment details or reasons for denial.

By tracking this EDI data, daisyBill helps providers identify trends, resolve billing discrepancies, and maintain transparency in the workers’ comp electronic billing process.

837 e-Bill Sent

California law requires Gallagher Bassett to accept workers’ comp e-bills and Second Review appeals submitted electronically by providers. daisyBill transmits all bills and appeals using the X12 837 EDI standard, as mandated by DWC Rule 7.1.

When Gallagher Bassett fails to accept e-bills compliantly, daisyBill resorts to non-EDI methods (fax, email, or mail) to submit paper bills for processing.

The table below shows how often Gallagher Bassett properly accepts e-bills sent via the required X12 837 EDI standard and how often Gallagher Bassett's failure forces providers to submit paper bills.

277 Acknowledgement (ACK) - Timeliness

California requires Gallagher Bassett to electronically send a 277 Acknowledgement (277 ACK) to the provider within two working days of receiving an e-bill. This notice confirms whether Gallagher Bassett accepted or rejected the e-bill for payment adjudication. If the 277 ACK indicates acceptance, it serves as proof that Gallagher Bassett received the e-bill for processing.

  • 277 Accept: Confirms that the e-bill was accepted for payment adjudication.

  • 277 Reject: Indicates that the e-bill was rejected, with an associated STC Category and STC Code explaining the reason.

  • STC Invalid – Reject Second Review: An improper rejection of a Second Review appeal using invalid STC Category and/or STC Code.

  • STC Invalid – Reject Injury Claim Valid: An incorrect rejection of an e-bill where the claims administrator previously paid another bill associated with the same injury claim.

  • STC Invalid – Reject Category/Code: A rejection where the STC Category and/or STC Code provided is invalid or not allowed.

CA Official Medical Fee Schedule

The California Official Medical Fee Schedule (OMFS) establishes the reimbursement amounts due to providers for medical treatment furnished to injured workers.

For Gallagher Bassett medical treatment bills, this table reflects the OMFS Reimbursement Due to daisyBill clients for medical treatment provided to injured workers. Gallagher Bassett Reimbursement Reduction reflects the amount Gallagher Bassett failed to pay daisyBill clients. The Gallagher Bassett Reduced Reimbursement reflects the reimbursement amount Gallagher Bassett ultimately reimbursed daisyBill providers.

Gallagher Bassett CALIFORNIA DATA - PENALTY & INTEREST

If Gallagher Bassett fails to remit payment within mandated time frames, California law requires the claims administrator to “self-execute” Penalty and Interest payments directly to the provider. Often claims administrators fail to self-execute these Penalities and Interest (P&I).

Using e-billing data, daisyBill calculates the Total P&I Due to daisyBill clients and the amount of P&I Gallagher Bassett reported paying our clients.

The Penalty & Interest Balance Due displayed here is the amount Gallagher Bassett failed to self-execute to daisyBill clients as mandated by California law.

Once a bill payment is 45 calendar days overdue, daisyBill calculates Penalty and Interest amounts owed. Total P&I Due may slightly overstate the amount owed by Gallagher Bassett in the instances where the underlying employer is a government employer, as California allows government employers 60 calendar days to timely reimburse workers' comp bills.

*EOR Missing Count reflects the instances where Gallagher Bassett failed to electronically send the provider an EOR, therefore, daisyBill could not calculate whether P&I is due for these e-bills where the EOR is missing. Data updates daily.
