Question:
If multiple spirometric determinations are necessary to complete a service, how many units can be reported?
Answer:
According to the National Correct Coding Initiative Manual for Medicare Services (chapter XI, section J.3.), only one unit of service shall be reported. For example, CPT® code 94070 describes bronchospasm provocation with an administered agent and utilizes multiple spirometric determinations as in CPT code 94010. A single unit of service includes all the necessary spirometric determinations.
