Reporting Cardiac Magnetic Resonance Absolute Quantitation of Myocardial Blood Flow (0899T, 0900T)
April 2025 pages 12-24 Reporting Cardiac Magnetic Resonance Absolute Quantitation of Myocardial Blood Flow (0899T, 0900T) For the CPT 2025 code set, two new Category III add-on codes (0899T, 0900T) were established to report the noninvasive determination of absolute quantitation of myocardial blood flow (AQMBF) using augmentative and assistive algorithmic analysis. Codes 0899T and 0900T provide additional information to help diagnose the causes of myocardial ischemia (ie, a lack of blood flow to the heart) and to determine its extent and severity. Parenthetical notes were added to the Category III section to clarify the reporting of these new codes...

Article Overview
This article explains a CPT 2025 update involving new Category III add-on reporting for cardiac magnetic resonance absolute quantitation of myocardial blood flow. It discusses the broader radiology and heart-subsection guidance changes, the relationship to other myocardial blood flow services, and how the new material is framed for clinicians and coding professionals who work with cardiac imaging and radiology coding.
Why This Topic Matters
The update affects how cardiac MRI myocardial blood flow services are described in CPT 2025 and helps coding professionals understand where the new guidance fits within the Radiology section and related cardiac imaging references.
