Receiving a warning message when using the CMGP01 to 10 modifiers?

Please don’t let the message deter you from using the correct modifier! A warning message is generated because WCB-Alberta’s system does not recognize CMGP01 to 10 as valid modifiers (although they are).

It is important that you submit the invoice with the correct modifier even though a warning has been generated. The invoice will be paid correctly through WCB’s payment system.
