PET Myocardial Imaging Studies (July 2020)
July 2020 pages 5-6 PET Myocardial Imaging Studies Several changes occurred in the Radiology/Cardiovascular System subsection of the Current Procedural Terminology (CPT®) 2020 code set to reflect new technology for myocardial imaging positron emission tomography (PET) and PET/computed tomography (CT) studies. CPT codes for myocardial PET studies (78459, 78491, 78492) were revised, and new codes (78429-78434) were established to describe bundled PET and CT performed concurrently for both attenuation correction and anatomic localization. In addition, the guidelines were revised and parenthetical notes were added to guide users in the appropriate reporting of these services. This article provides an...

Article Overview
This article explains July 2020 changes affecting cardiac PET myocardial imaging in CPT, with emphasis on updated descriptors, newly added PET/CT-based reporting options, revised guidelines, and related instructional notes. It is relevant to coders, auditors, and reimbursement professionals working with nuclear medicine and cardiovascular imaging services. The article also discusses how the update fits with related stress testing, CT transmission imaging, and myocardial blood flow quantitation guidance.
Why This Topic Matters
The update changes how several cardiac PET imaging services are described and organized in CPT, which affects accurate claim reporting and code selection workflows. It also ties the PET myocardial imaging guidance to related CT and stress-testing instructions, making it important for practices that bill these services.
