Cardiopulmonary Monitoring Is Often Bundled
Remember that cardiopulmonary monitoring services (e.g., 94770 Carbon dioxide, expired gas determination by infrared analyzer) are regularly bundled as inclusive components of procedures reported by the performing provider (e.g., surgeon or anesthesiologist). In such cases, you would not report the cardiopulmonary monitoring independently.
Chapter 1 of the National Correct Coding Initiative Policy Manual for Medicare Services formalizes this policy, stating, “Many procedures require cardiopulmonary monitoring either by the physician performing the procedure or an anesthesia practitioner. Since these services are integral to the procedure, they are not separately reportable. Examples of these services include cardiac monitoring, pulse oximetry, and ventilation management (e.g., 93000-93010, 93040-93042, 94760, 94761, 94770).”
