I have a patient who was admitted to observation late on 11/28, then on 11/29 our doctor dictated both the H&P and the discharge. It is my understanding we cannot bill both so we billed the 99217 discharge. Insurance denied stating to "resubmit the claim with the qualifying service". Should we be billing the H&P instead? Seems like I've been getting a lot of denials lately related to observation. Have there been changes?
