I am looking Sara for a code to cover Rh- and have not found it yet. This is ignorance on my part. I will find something for you though. It is necessary to document that the patient is Rh- as this can affect the baby's health. The mother is usually fine. Now they don't have as many complications because of the shot Rh immunoglobin, that can be given and better testing. One shot is given prior to deliver and I think one afterwards. If I remember correctly it is only done once in a life time so future Rh+ babies are not affected.
You see your blood type is not just a letter but - or + and that is called the Rh factor. This doesn't cause any trouble unless the Mother is - and the baby is +. Then you have a situation where there are two different blood types so to speak. Now, if there is blood transfer then the baby's body will go into rejection mode. With the Rh immunoglobin, which I think we called the Rh factor shot back when I did clinical work, that protects the baby. I believe it adds a protein layer in the Mother's blood system. It is very detailed and I can't remember all of it. (This would make a great webinar slide though).
Sara I think is looking for a Dx code that will show the Mother's Rh factor -. If anyone else finds it before I do jump right in.
Oh, Carolyn I think maybe the no mention of complication is meaning that nothing has happened, YET. The potential is there.
