Could use some help. Did a Diagnostic Bronchoscopy thru a tracheostomy tube, L&R mainstem bronchus & trachea viewed. EBUS was used to review the lesion. Thinking of 31615 but then EBUS can't be coded because there is no primary code. CPT 31622 is a bronchoscopy but not thru the tracheostomy tube. Is the hospital to code only 31615. Thoughts? Thanks Buttercup
