I have been using lytec with xlink - its great - all encounters show up on my biller's screen as soon as I am done.I have an inhouse biller - I have a cardiology practice that does several office tests .We still do the paper superbill which is only as a check for the biller - cant trust technology for this important task 100% !!. It has cut down the work this expensive person in my office has to do by automaticallty inputting the bill/change in demographics/insurance etc., thus paying for itself fast .
