Unwind PFT Coding Distinctions
Published on Sat Sep 26, 2009
Question: Can you help delineate the difference among the different types of pulmonary function testing codes? Massachusetts Subscriber Answer: Pulmonary function tests (PFTs) can measure the patient's lung volumes, airflow, compliance, gas transfer, and other physiologic parameters. If the pulmonologist performs simple spirometry which graphs the vital capacity and expiratory flow or if the flow volume loop (FVL) is not complete use 94010 (Spirometry, including graphic records, total and timed vital capacity, expiratory flow rate measurement[s], with or without maximal voluntary ventilation). If an FVL is measured without bronchodilator administration, use 94375 (Respiratory flow volume loop). If the physician performs spirometry pre- and postbronchodilator administration, use 94060 Bronchodilation responsiveness, spirometry as in 94010, pre- and postbronchodilator administration). Pay attention to certain codes that the Correct Coding Initiative (CCI) has bundled together. For instance: • 94010 is bundled with 94375, and • 94010 and 94375 are bundled with 94060. The technical [...]
