Peyronie's Injection

Patient was seen in the office he brought own meds and Dr. did the injection. Does any body know if I can bill the injection code 54200 with the E/M visit. Dr dictates a full note and mentions injection and also 25 min spent with pt with more than 50% counseling.
He is spending the entire visit at the patient's side and monitors and explains the procedure and progress.

Is it appropriate to bill the procedure and E/M for the time spent monitoring after the injection.
