An EP study and ablation was scheduled, however was cx due to pt.'s respiratory status after induction of general anesthesia. I am wondering if I can bill for the physician's involvement of this scenario after the pt was extubated:

A couple minutes after extubation, the pt developed SVT at rates of 180-200. There may have been retrograde p waves at the end of the QRS complexes however they were difficult to see. Adenosine 6 mg was administered and this converted the tachycardia however the pt reverted to SVT almost immediately. This was repeated with the same effect.
We adminstered a small dose of Midazolam during the last dose of adenosine which resulted in restoration of sinus rhythm.

Any suggestions?
