The carriers frequently file inaccurate, perjurous, and incomplete forms with the WCB. The WCB does not care. For instance, every C-7 (notice of controvery disputing a claim) says on the form that the carrier must attach documentation to support its claim. They never do. Judges don't care, and the WCB doesn't care. If a worker filed a similar document with mis-stated or missing information, the worker is heavily penalized. Not the carrier.
All to frequently we have the carrier file a C-8 stating that payment was mailed on the certain date. The date is critical, as it may determine whether there is a penalty for a late payment. When the carrier files that document, affirming that the information is correct, and we then produce the envelope that shows the payment was days later, we get the penalty for proving the late payments. But no one seems to care that the carrier filed a fraudulent statement attesting to a certain date of payment. It's viewed as "standard business practice".
There is a dual standard in WC. If you read over this messageboard, you will see example after example. Understand that is the way it operates. Then figure out how to use that to your advantage. I'm afraid it is waste of time to point out inaccuracies, incompetence, or outright fraud by the carriers--no one seems to care. I keep doing it, and it falls on deaf ears.
As a recent example, the law provides that IMEs will be paid according to the WCB medical fee schedules. That is done to avoid a carrier being able to purchase an opinion which favors its position. When I happen to come across a bill for an IME (incompetence of carriers in sending it to me) that far exceeds the fee schedules, I send it to the WCB. The response is that the WCB does not monitor IME fees. There is no place where the amount paid to an IME is filed. When you see your doctor, and he/she bills $34.00, it is sent to the carrier, the WCB--and the carrier objects if the bill is for $1.00 more than the fee schedule provides. The IME, however, may bill $2,000--and that bill is not filed anywhere. No one is given notice of how much is paid for IMEs, and there is a reason--it would outrage those who work in the system, and outside the system, to realize how much is paid for these opinions.
Get used to the fact that the WC system is not fair, not just, and is not likely to change in the near future. Figure it out so that you can use it to your best advantage. If you get upset over the unfairness and inequity, it will drive you crazy.
