We have an insurance requesting a CPT code on the rev code 720 which is an L&D rev code. The charge is for OB Assessment/Monitor 1-2 hours. I cannot find a code that works for this as they all seem to be for when the patient actually delivers but this patient does not. They use monitoring belts on the abdomen and a BP cuff. Pt came in with abd pain and high BP. Any suggestions? Thanks!
