I was following the practice of billing the ED visit 99283 POS 23 (ED) for a patient who presents in labor to the ED. If she delivers same day that code is under 59409 POS 21 (Inpt) and billed. I cannot find anything on this site in writing so I can verify/prove what is correct to the billing dept. They state POS should be 22 (Observation) on the ED code. I disagree.
Thanks for any help
