Coronary FFR with Coronary Computed Tomographic Angiography (75574, 75580) (March 2024)
March 2024 page 14 Coronary FFR with Coronary Computed Tomographic Angiography ( 75574 , 75580 ) For the CPT 2024 code set, Category I code 75580 and two parenthetical notes were established to report a noninvasive estimate of coronary fractional flow reserve (FFR) derived from augmentative software analysis of the data set from a coronary computed tomography angiography (CCTA). Category III codes 0501T - 0504T and three associated parenthetical notes were deleted to accommodate the new code. This article provides an overview of these changes and additions.
