Question:

What billing tips can you provider for code 94200 (maximum breathing capacity, maximal voluntary ventilation [MVV]), which we often use as a preoperative procedure?

Answer:

MVV is considered a component of the following codes, so billing 94200 on the same date of service (DOS) as the following is double billing and will result in a denial. If a MVV is performed separately on the same DOS as another MVV or a spirometry, be sure to append an appropriate modifier.

94010 Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement(s), with or without maximal voluntary ventilation
94060 Bronchodilation responsiveness, spirometry as in 94010, pre- and post-bronchodilator administration
94070 Bronchospasm provocation evaluation, multiple spirometric determinations as in 94010, with administered agents (e.g., antigen[s], cold air, methacholine)

Also be aware that in procedure-to-procedure edits of the National Correct Coding Initiative (NCCI), code 94200 is a column 2 code when billed with the above codes and a modifier is allowed.
