Answer: Code 94375 (respiratory flow volume loop) will always be denied when billed with code 94010 (spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement[s], with or without maximal voluntary ventilation).
According to the national Correct Coding Initiative (CCI), version 6.0, code 94375 is bundled into code 94010. The CCI has assigned modifier status 0 to code 94375, which means that no modifier can ever be applied to code 94375 that will allow for its reimbursement.
