ECMO / ramp study

Date: Jul 6, 2022

Question:

I am not sure how to code this. I'm hoping you can help explain what they are doing here and what codes are best. 

"Patient had CABG and on ECMO days ago now in shock and going back to operating room. Esmarch dressing removed . The mediastinum was evacuated of clot. Rt pleural space was opened and fluid evacuated here was small in amount. The patient then underwent a ramp study, epinephrine increased. Ejection fraction was 55%. We weaned to 3/4, intermittently clamping the LV vent for a limited time because patient was not heparinized. At the end of the 5 minute period of clamping, Lactate was stable. EJ fraction was unchanged. The balloon was paused with good pulsatility, but not ready for weaning. Quikclot and Esmarch dressing replaced."

What is the code for the RAMP study? I assume it has to do with the ECMO? I think the mediastinal washout is 35820?
