Hi Eastland Dental Center! Great question! What most of our clients prefer to do for secondary claims in DW is: – open/edit the claim in DW. Change the medical insurance company information at the top to the secondary insurer, using the contacts list – add any payments to the claim as needed from the primary insurer in field 29 (you will need to send along a copy of the EOB from the primary insurer with this claim as well) – Swap the insurance ID/policy information as needed between field 9, and fields 1 & 11 – In field 19, enter the words: SECONDARY CLAIM – print & send, or submit electronically if you do electronic claims! – it is a good idea to leave a “note” in the notes area at the top middle of the claim form, just indicating the claim was changed to a secondary claim and submitted. Hope this helps!
