CMS-1500 form?? Deduct the amount from box 30?
someone's program isn't set up right. It should deduct the amount from box 28
box 28 total charge - box 29 amount paid=box 30 balance due. However it doesn't show the non allowed thats why the EOB needs to be sent. Sounds fishy to me the only insurance that I personally bill that doesn't allow an EOB is DMAP(oregon medicaid) and I have to fill out a separate form for them. I would worry about the Insurance stating that the claim has not been filled in correctly and reject the claim. CMS-1500 forms that are sent on paper are generally scanned so if it's programed to see if box 29 is filled in it would give the insurance a reason to not process. I have had claims reject out because my line up was off so when it was scanned it wouldn't process.
I personally have never had a problem with box 29 being filled in but could see a delay in payment if it were not.
