A system maintenance error caused invoices to be rejected if they were submitted between 11:30 PM October 16 to 6:00 PM October 19 Pacific Time. When you check your invoice status, you’ll see Explanation of Benefit (EOB) codes 554 or 557. WorkSafeBC will recover the affected invoices and reprocess them on your behalf. They’ll be processed and paid as usual. No further action is required. If you’ve already resubmitted the rejected invoice, you may see a line item marked as a “duplicate” – this is an expected result of WorkSafeBC reprocessing previously rejected invoices and does not affect their payment.
