navigational bronchoscopy

Hi,

Please help me to understand better

if navigational bronchoscopy was used during the session where bronchial lavage and transbronchial biopsy was done.

then should the codes be reported as 31628

31624

31627

or are the codes are to be reported as 31628

31627

31624

31627

please let me know if 31627 is reported for every procedure that is performed.

thank you very much
