I know this sounds crazy, but can someone guide me to the documentation stating I cannot bill a primary surgeon and an assistant surgeon on the same claim. I bill for a group of Ob/gyns and very commonly they assist one another. We bill under the same NPI and tax id. I cannot find ANY documentation stating they cannot be billed on the same claim. I bill each line appropriately with the correct physician listed and a modifier 80 on the assist but priority health is telling me this comes up against a new edit. I cannot find this edit anywhere!! Please help.
