MRI of the heart is currently differentiated from MRI and MRA of the chest. Please reference the following table for
a listing of MRI codes.

MAGNETIC RESONANCE
IMAGING
MRI of the chest
71550 Magnetic resonance (eg, proton)
imaging, chest (eg, for evaluation
of hilar and mediastinal
lymphadenopathy); without
71551
71552
contrast material
with contrast material
without contrast material, followed
by with contrast material(s) and

MRA of the chest
71555 Magnetic resonance angiography,
chest (excluding myocardium),
with or without contrast
material(s)
Cardiac MRI for morphology 75552 Cardiac magnetic resonance
(Useful in assessment of the
imaging for morphology, without
heart structure for
contrast material
diagnostic evaluation of
75553
congenital heart disease,
with contrast material
pericardial disease, tumors,
cardiomyopathies, valvular
heart disease, and ischemic
heart disease)1
Cardiac MRI for function
(Codes used to describe
observation of cardiac
function with or without
observing morphology.)1
75554 Cardiac magnetic resonance
imaging for function, with or
without morphology;
75555 complete study
limited study
Cardiac MRI for mapping
75556 Cardiac magnetic resonance
(Used to assess the great
imaging for velocity flow mapping
vessels, including the
thoracic aorta (for detection
of aneurysm, dissection, or
co-arctation), the main
pulmonary artery (to assess
its size), and the relationship
between these two vessels
(to assess patients with
congenital heart disease).1
MRA of the heart
76498 Unlisted magnetic resonance
procedure (eg, diagnostic,
interventional)
