When patients have two carriers, one of them being MSS, the system wants to default MSS as the primary carrier even though MSS is always the secondary carrier. If we could override the system, we could send claims electronically to the primary carrier first (Manulife, Sunlife, GroupHealth, etc) without an error message saying we need to send the claim to the primary carrier (MSS is always secondary even though the patient is also the subscriber). This is also the case with cash insurance accounts (Can Health and Dental for example). They are always secondary regardless of the subscriber of the primary insurance carrier.
