Sometimes electronic claims do not process properly if there is a secondary insurance submitted on the claim.
This does not happen with all clearinghouses and all claims, but if you find you an instance where you want to simply submit the selected insurance as the only carrier on the claim, check the HIDE OTHERS box on the invoice.
Checking this box submits the selected insurance carrier only, and hides all other insurance from the electronic claim.
In the example above, you want to send a claim to the secondary insurance carrier, Travelers, and not show the primary carrier, Medicare, anywhere on the claim. Select Travelers as the Bill To insurance, and check the HIDE OTHERS box next to the insurance carriers list on the invoice.
The claim will be submitted as if Travelers was the only insurance carrier.
