Final answer:
No modifiers should be added to the procedure codes for a bronchoscopy with biopsy of the left bronchus.
Step-by-step explanation:
No modifiers should be reported for the procedure codes. When reporting a bronchoscopy with biopsy, the codes do not require any specific modifiers. Modifiers such as -50 (Bilateral procedure), -51 (Multiple procedures), and -59 (Distinct procedure service) are used in other situations to indicate specific circumstances, but they are not applicable in this case. Therefore, no modifier should be added to the procedure codes for a bronchoscopy with biopsy of the left bronchus.
