Another doctor (not one I bill for) has been telling my doctor that if you perform a group of services on one day that is more than the usual and customary that would be reimbursed for one day, it is ok to bill them with 3 dates of service so that they will be covered. For example, doctor performs 20 xyz tests on 1/1/15, but knows insurance will pay for only 8 per day. Doctor then bills 8 xyz tests for 1/1/15, 8 for 1/2/15, and 4 for 1/3/15. I am pretty sure that this is NOT ok, but I would like confirmation.
