You cannot bill 94010 and 94060 together on the same date for the same patient. CPT 94060, which measures bronchodilation responsiveness, inherently includes the services performed in a standard 94010 spirometry. According to the National Correct Coding Initiative (NCCI) 2026 edits, reporting both will result in a denial of the 94010 claim because it’s considered a component of the more comprehensive procedure.
