AmTrust CALIFORNIA DATA - REIMBURSEMENT STATISTICS

CA Average Days to Pay

For each bill sent from daisyBill software to AmTrust, our technology tracks the count of business days it took AmTrust to process the bill.

For the listed California workers’ comp fee schedules, this table reflects the average count of business days from AmTrust’s receipt of a bill until the daisyBill client received an explanation of review (EOR) and payment from AmTrust.

* California requires claims administrators to pay e-bills for medical treatment within 15 working days of receipt of the e-bill.

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. However, rather than reimbursing providers the reimbursement amounts due per the OMFS, AmTrust uses Preferred Provider Organizations (PPOs) to reduce the reimbursements paid to providers.

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

AmTrust CALIFORNIA DATA - PENALTY & INTEREST

If AmTrust 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 AmTrust reported paying our clients.

The Penalty & Interest Balance Due displayed here is the amount AmTrust 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 AmTrust 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 AmTrust 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.

AmTrust CALIFORNIA DATA - EDI COMPLIANCE

Commencing October 2012, California law mandates claims administrators must accept the electronic submission of complete medical bills (‘e-bills’) from providers. For e-bills, the California Division of Workers’ Compensation (DWC) Medical Billing and Payment Guide establishes timeframes by which claims administrators (aka payers) must acknowledge, object to, pay, and provide an Explanation of Review (EOR) in response to all e-bills sent by workers’ comp providers.

Using the collective data from daisyBill clients’ e-bills, below the data reports how often AmTrust both complied and failed to comply with the mandated California e-billing requirements and timeframes when processing e-bills sent by daisyBill clients.

X12 837 e-Bill Acceptance

California law requires AmTrust to accept workers’ comp e-bills from providers, including accepting Second Review appeals providers send electronically.

daisyBill transmits all bills and Second Review appeals electronically to AmTrust using the X12 837 EDI standard as required by DWC Rule 7.1. When AmTrust fails to compliantly accept an e-bill, daisyBill uses a non-EDI method (fax, email or mail) to transmit a paper bill to AmTrust for processing.

For bills submitted last quarter, the table below reports the frequency at which AmTrust compliantly accepts e-bills daisyBill compliantly sent using the required X12 837 EDI standard. The table also reports the frequency at which AmTrust fails to compliantly accept e-bills, thereby forcing providers to submit non-EDI paper bills to AmTrust.

X12 277 Acknowledgement - Timeliness

Within two working days after receipt of an e-bill, AmTrust must electronically send the provider a X12 277 Acknowledgement (277 ACK) verifying that AmTrust either accepted or rejected the e-bill for payment adjudication. Upon receipt of a 277 ACK that accepts an e-bill, the provider has proof that AmTrust received the e-bill for processing.

The table below reports how often AmTrust compliantly sends 277 ACK notices to daisyBill clients within two working days of receipt of the e-bill.

X12 277 Acknowledgement - Invalid e-Bill Rejections

For rejected e-bills, the 277 ACK includes STC segments with a Claim Status Category Code (STC Category) and a Claim Status Code (STC Code) explaining the reason for the e-bill rejection. The DWC allows claims administrators to reject e-bills only for a strictly defined set of (mostly technical) reasons. A 277 ACK cannot function as an electronic Explanation of Review (e-EOR) to deny payment. 

The table below lists the instances where AmTrust sent 277 ACKs with invalid STC Category and STC Codes that non-compliantly rejected e-bills for reasons other than allowed by the DWC. Rather than properly returning electronic Explanations of Review (e-EORs) explaining reasons for payment denial, AmTrust non-compliantly rejected the e-bills with improper STC Category and Codes.

X12 835 EOR

DWC Rule 7.1 requires AmTrust to electronically send an Explanation of Review (EOR) to the provider using the X12 835 EDI standard. When a provider sends an Original e-bill, AmTrust must electronically send the EOR within 15 working days after receipt of the e-bill from the provider. For Second Review e-bills, AmTrust must electronically send the provider an EOR within 14 calendar days after receipt of the Second Reiew e-bill from the provider.

The table below reports the frequency at which AmTrust compliantly sends X12 835 EORs to daisyBill clients.
