Summary of Direct Crosswalk Codes Decision Regarding Myocardial Perfusion Imaging
There were four primary codes (78460, 78461, 78464 and 78465) and two add-on codes (78478 and 78480) active prior to January 1, 2010 for myocardial perfusion imaging. All six codes expired as of December 31, 2009. Four new replacement codes (78451-78454) were created effective January 1, 2010 to replace the six myocardial perfusion imaging codes listed above. The four new replacement codes have descriptions that include the two add-on services. Due to the unique nature of this situation, UnitedHealthcare intends to:
** Crosswalk the contracted fee from 78460 to 78453;
** Crosswalk the contracted fee from 78461 to 78454;
** Crosswalk the contracted fees from 78464 + 78478 + 78480 to 78451; and
** Crosswalk the contracted fees from 78465 + 78478 + 78480 to 78452.

Coverage Indications, Limitations, and/or Medical Necessity
Noninvasive testing in the outpatient setting to assess coronary artery disease (CAD) and left ventricular (LV) dysfunction may be accomplished utilizing conventional exercise testing or by measuring the distribution of nuclear medicine reagents during physiologic or pharmacologic stress.
Cardiovascular stress testing, also called an exercise stress test (EST), exercise electrocardiogram, exercise treadmill test (ETT), graded exercise test, or stress electrocardiogram (ECG), is used to provide information about how the heart responds to exertion. It usually involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty, while the electrocardiogram, heart rate, and blood pressure are monitored. The same measurement may be obtained with the substitution of echocardiography for a standard ECG. Echocardiography is used to image cardiac structures and function and also flow direction and velocities within cardiac chambers and vessels. Usually these images are obtained from several positions on the chest wall and abdomen using a hand-held transducer.
In many instances, exercise testing (without imaging) may be combined with imaging procedures, such as myocardial perfusion imaging, radionuclide ventriculography, echocardiography, or other imaging procedures.
There are 3 principle types of stress tests which do not involve the measurement of radio-labelled distribution within the body. These include:
• Exercise stress test (EST) is normally the first stress test performed. The patient walks on a treadmill or similar device while being monitored to measure endurance with an end-point of symptoms, ECG, or echocardiographic changes that suggest coronary under-perfusion. EST is without imaging. An EST must include an ECG that can be interpreted for ischemia, and the patient must be capable of exercise on a treadmill or similar device generally at 4 METs or greater (i.e., able to walk four blocks without stopping, can climb two flights of stairs without stopping). An abnormal EST includes any one of the following: ST segment depression, development of chest pain, significant arrhythmia (especially ventricular arrhythmia), or hypotension.
• Dobutamine, Dipyridamole, or Adenosine Stress Test is used in people who are unable to exercise. A drug is given to make the heart respond as if the person were exercising. This way the doctor can still determine how the heart responds to stress, but no exercise is required.
• Stress echocardiogram is a graphic outline of the heart’s movement. A stress echo can accurately visualize the motion of the heart’s walls and pumping action when the heart is stressed; it may reveal a lack of blood flow that isn’t always apparent on other heart tests.
The main task of Nuclear Cardiology and Nuclear Medicine is not the representation of anatomy, as in traditional Diagnostic Radiology; rather, it is the non-invasive visualization of functional, metabolic processes. In diagnostic Nuclear Medicine, the subject first incorporates tracer amounts of a radioactively-labelled molecule. Once the tracer molecule is properly distributed inside the body, imaging techniques visualize the metabolism of the substance by measuring the distribution of the radioactively-labelled molecule through externally emitted radiation.
The specific imaging technique (perfusion versus ventricular function) and the reason for the imaging determine what radionuclide agent is employed. In its simplest terms, a perfusion study utilizes an imaging isotope agent that reflects myocardial blood flow and, dependent on the agent and timing of image acquisition, the presence of scar and/or ischemia. Ventricular function studies utilize specific imaging isotopes to outline the borders of the left ventricular endocardium or to identify the ventricular blood pool independent of the surrounding myocardium. The motion of the left ventricle is synchronized with the electrocardiogram to generate wall motion and ejection fraction information. Both modalities may use rest and exercise images.
In instances where an exercise test cannot be performed, dipyridamole, adenosine or other provocative agents may be used to alter coronary flow, thereby unmasking a suspected lesion in the coronary bed. The acquisition of the images may be planar (single plane) or by multiple planes with computer integration, Single-Photon Emission Computer Tomography (SPECT).
Radionuclide imaging may be employed in the assessment of a variety of conditions associated with primary coronary artery disease. Some of these conditions include:
- Assessment of the functional level and prognosis of patients afflicted with angina or coronary artery disease.
- Diagnostic evaluation of patients with chest pain or other signs and symptoms highly suggestive of ischemic heart disease and who have uninterpretable or equivocal ECG changes caused by drugs, bundle branch block or left ventricular hypertrophy.
- Evaluation of myocardial perfusion and or function before and after coronary artery bypass surgery or other reperfusion procedures.
- Quantification and surveillance of myocardial infarction and aid in the determination of the prognosis in patients with infarction.
- Assessment of anomalies of coronary circulation in certain congenital forms.
- Evaluation of ventricular function in patients with non-ischemic myocardial disease, including myocardial disease due to valvular heart diseases.
- Evaluation of a patient receiving chemotherapeutic drugs that are potentially cardiotoxic (e.g., adriamycin).
- Assessment of viable myocardium and non-viable myocardium in patients anticipating partial myocardial surgical resection.
- Assessment of ventricular function and/or myocardial perfusion in patients in whom major vascular, thoracic, CNS or intra-abdominal surgery is planned.
The usual indications for performing myocardial perfusion imaging (MPI) procedures are:
New onset of symptoms in patients having probability of coronary artery disease (CAD);
A significant change in symptoms in an individual with known coronary artery disease;
Suspicion of chest pain of cardiac origin;
Probability of coronary artery disease (multiple risk factors and strongly suggestive symptoms) with an abnormal exercise ECG;
Abnormal cardiovascular diagnostic studies in asymptomatic patients with significant cardiac risk factors, e.g. diabetes mellitus;
Risk of a subsequent cardiac event following acute myocardial infarction;
Preoperative evaluation prior to increased risk noncardiac surgical procedures in the moderate cardiac risk patient with recent cardiac history, symptoms, or findings. Cardiac catheterization should be considered in the high risk cardiac patient’;
Postoperative assessment following myocardial revascularization procedures (e.g.,CABG, PTCA) in symptomatic patients;
Assessing postoperative asymptomatic patients after PTCA or CABG, such as in patients with an abnormal ECG response to exercise or those with rest ECG changes precluding identification of ischemia during exercise;
Assessing the patient with angiographic proven disease when it is necessary to identify the “culprit” lesion for revascularization with surgery or angioplasty;
Differentiating ischemic and non-ischemic cardiomyopathy;
Evaluating right ventricular function in patients with pulmonary hypertension; or
Evaluation following cardiac transplantation.
- Given the limitations of uptake, low photon energy and redistribution, the cardiac blood pool codes and perfusion imaging codes are not generally covered on the same date of service. However, in light of the predictive value of exercise-induced changes in ejection fraction, an exception will be made to allow first pass, single study with exercise along with the appropriate perfusion studies. Providers who bill this service must certify within their records that their laboratories are specially equipped to process such studies.
- All cardiovascular nuclear tests and stress tests must be referred by a physician or a qualified non-physician. (i.e., a Nurse Practitioner (NP) or Physician Assistant (PA)).
- Safe and effective.
- Not experimental or investigational (exception: routine costs of qualifying clinical trial services with dates of service on or after September 19, 2000, which meet the requirements of the clinical trials NCD are considered reasonable and necessary).
- Appropriate, including the duration and frequency that is considered appropriate for the service, in terms of whether it is:
- Furnished in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient’s condition or to improve the function of a malformed body member.
- Furnished in a setting appropriate to the patient’s medical needs and condition.
- Ordered and furnished by qualified personnel.
- One that meets, but does not exceed, the patient’s medical need.
- At least as beneficial as an existing and available medically appropriate alternative.
In the absence of symptoms following normal coronary angiography.
When there is no probability of intervention:
risk too high;
patient refuses to consider; or
As repetitive, frequent testing in the absence of changing clinical parameters, especially in individuals with known CAD.
Screening for coronary disease is not a Medicare covered indication.
Providers are reminded to refer to the long descriptors of the CPT codes in their CPT book. The American Medical Association (AMA) and the Centers for Medicare & Medicaid Services (CMS) require the use of shortCPT descriptors in policies published on the Web.

Billing and Coding Guidelines
Q: Which CPT codes should be used when describing MPI SPECT studies?
CPT CODE 78451 – Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); single study, at rest or stress (exercise or pharmacologic)
CPT CODE 78452 – Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); multiple studies, at rest and/or stress (exercise or pharmacologic) and/or redistribution and/or rest reinjection
93015-93018: Cardiovascular stress testing. Choose appropriate code(s) from the stress test series.
*** Note: Also bill any appropriate HCPCS code for the use of radiopharmaceuticals or drugs administered during the MPI study or stress test.***
Q: How do MPI Planar studies differ from MPI SPECT studies?
A: While SPECT technology allows the nuclear cardiologist to view a threedimensional image of a specific area, planar imaging only produces a two-dimensional image. Most nuclear cardiologists utilize SPECT imaging because it allows them to finely examine an image in multiple planes. Procedure codes 78453 and 78454 are used to describe MPI Planar studies.
2016 CPT and ICD-10-CM Code and Reimbursement Information
Cardiac Stress Testing
The following is a summary of Current Procedural Terminology (CPT®) codes commonly used for various exercise stress procedures performed with a Midmark cardiac stress testing system. This information is provided only as a guide and is not intended to replace any official recommendations or guidelines, and does not constitute a promise or guarantee by Midmark regarding coverage or payment. Always check with the specific payer for the appropriate use of any CPT or ICD-10 codes. Physician fee schedule values listed are based on a national average and are rounded for brevity. Specific
payments vary geographically. Codes and rates are subject to change. It is the responsibility of the provider to determine the correct coding for services provided.
78452 : Nuclear stress : Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); multiple studies, at rest and/or stress (exercise or pharmacologic) and/or distribution and/or rest reinjection.
Q: The above example used 78452 to describe the imaging study. Can I use any of the CPT codes that describe MPI SPECT?
A: No! When deciding which code to use for any procedure, it is critical that coders select the name of the procedure or service that accurately identifies the service performed and not just choose a CPT code that merely approximates the service provided.
Myocardial Perfusion Imaging, Tomographic
An authorization is given for CPT code 78451 “Myocardial perfusion imaging, tomographic (SPECT); single study, at rest or stress”. The cardiologist performs CPT code 78452 “Myocardial perfusion imaging, tomographic (SPECT); multiple studies, at rest and/or stress and/or redistribution and/or rest reinjection”. The provider does not need to contact Care to Care to modify the authorization as CPT code 78452 is included in the same code group as CPT code 78451.
MPI, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); single study, at rest or stress (exercise or pharmacologic)
78451 MPI, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); multiple studies, at rest and/or stress (exercise or pharmacologic) and/or redistribution and/or rest reinjection 78452
* The most commonly performed myocardial perfusion imaging are single (at rest or stress, CPT®78451) and multiple (at rest and stress, CPT®78452) tomographic SPECT studies.
o Evaluation of the individual’s left ventricular wall motion and ejection fraction are routinely performed during MPI and are included in the code’s definition.
o First pass studies, (CPT®78481 and CPT®78483), MUGA, (CPT®78472 and CPT®78473) and SPECT MUGA (CPT®78494) should not be reported in conjunction with MPI codes.
o Attenuation correction, when performed, is included in the MPI service by code definition. No additional code should be assigned for the billing of attenuation correction. Multi-day Studies: It is not appropriate to bill separately for the rest and stress segments of MPI even if performed on separate calendar dates. A single code is assigned to define the entire procedure on the date all portions of the study are completed.
* 3D rendering, (CPT®76376/CPT®76377), should not be billed in conjunction with MPI.
* Separate codes for such related services as treadmill testing (CPT®93015 – CPT®93018) and radiopharmaceuticals should be assigned in addition to MPI.
Myocardial Perfusion Imaging (CPT codes 78451, 78452, 78453, and 78454)
For CPT code 78451 (Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); single study, at rest or stress (exercise or pharmacologic)), the AMA RUC recommended 1.40 work RVUs, while the AMA RUC recommended 1.75 work RVUs for CPT code 78452 (Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantification, when performed); multiple studies, at rest and/or stress (exercise or pharmacologic) and/or redistribution and/or rest reinjection). Upon review of the AMA RUC recommendations for these codes, it was unclear what methodology the AMA RUC used to calculate the recommended work RVUs for CPT code 78451.
Therefore, we disagreed with the AMA RUC-recommended work RVUs of 1.40 for CPT code 78451 and believe the work RVUs for the survey 25th percentile were more appropriate. Therefore, we assigned interim final work RVUs of 1.38 to CPT code 78451 for CY 2010.
For CPT code 78452, we disagreed with the reference code used, CPT code 70496 (Computed tomographic angiography, head, with contrast material(s), including noncontrast images, if performed, and image postprocessing (work RVUs = 1.75)). We believe CPT code 78452 is comparable to CPT code 73219 (Magnetic resonance (eg, proton) imaging, upper extremity, other than joint; with contrast material(s) (work RVUs = 1.62)), which has the same pre-, intra-, and post-service time. Therefore, we assigned interim final work RVUs of 1.62 to CPT code 78452 for CY 2010.
We accepted the CY 2010 recommendations of the AMA RUC for the direct PE inputs for CPT codes 78451, 78452, 78453, and 78454 (75 FR 61955).
Comment: Several commenters disagreed with the interim final work RVUs assigned by CMS for these two services. The commenters pointed out that the specialty and AMA RUC recommendations for both of these services already reflected a tremendous reduction from the work RVUs for the services as reported by multiple component codes in previous years and expressed disappointment that additional reductions were made by CMS. The commenters explained that in an effort to maintain relativity between CPT codes 78451 and 78452, the recommended RVUs for 78451 were derived by calculating the relationship between the median survey RVUs for CPT codes 78451 and 78452 and maintaining this relationship between the recommended RVUs for CPT codes 78451 and 78452. That is, the survey work RVU relationship between CPT code 78451: 78452 is [1.50 : 1.87], leading to the same relationship between the AMA RUC-recommended RVUs for 78451 : 78452 of [1.40 : 1.75]. The AMA RUC agreed that the computed work RVUs, 1.40 for CPT code 78451, maintain the relativity of the original survey data and provide an appropriate measure of the work for CPT code 78451.
The commenters believe that CMS does not have the special expertise necessary to choose a different reference code than the code selected by the multispecialty AMA RUC panel and disagreed with the reference code used by CMS for establishing work RVUs for CPT code 78452. The AMA RUC pointed out that the reference code has no associated computer post-processing analysis, requires the interpretation of fewer images, and has no additional cine-motion images to analyze and interpret, all of which are included in the myocardial perfusion imaging procedures.
The CMS Manual System, Pub. 100-8, Program Integrity Manual, Chapter 13, Section 5.1, outlines that “reasonable and necessary” services are “ordered and/or furnished by qualified personnel.” Services will be considered medically reasonable and necessary only if performed by appropriately trained providers. A qualified physician for this service/procedure is defined as follows: A) Physician is properly enrolled in Medicare. B) Training and expertise must have been acquired within the framework of an accredited residency and/or fellowship program in the applicable specialty/subspecialty in the United States or must reflect equivalent education, training, and expertise endorsed by an academic institution in the United States and/or by the applicable specialty/subspecialty society in the United States.
The presence of risk factors for CAD, absent disease activity, is not a Medicare-covered indication for noninvasive testing. Screening for coronary artery disease in asymptomatic patients is not considered reasonable and necessary.
Patient selection should be based on clinical grounds. Pretest probability is based on age, gender, symptoms, and cardiac risk factors. Selection of the test should be made within the context of other testing modalities so that the expected information does not become redundant. In the instance where regional wall motion abnormalities and ejection fraction have been assessed, during the same episode of care, by other testing modalities (i.e. echocardiography), the medical necessity of repeating this assessment through the use of nuclear imaging modalities must be clearly documented in the medical record. The routine and repetitive monitoring of such patients beyond the first stress echo or MPI, in the absence of a documented clinical exacerbation (i.e., new symptoms or progression of existing symptoms) is not considered medically necessary.
MPI SPECT/PET and stress echo are not covered in patients with low pretest probability, interpretable ECG, and the ability to exercise.
MPI SPECT/PET and stress echo pre-operative evaluation for low risk non-cardiac surgery is not covered.
MPI SPECT/PET and stress echo are not covered for the pre-operative evaluation of planned intermediate risk, non-cardiac surgery, and the patient is able to exercise.
MPI SPECT/PET and stress echo are not covered for routine risk assessment for asymptomatic patients with known CAD, who have not had a revascularization procedure.
MPI SPECT/PET and stress echo are not covered for pre-operative, asymptomatic patients undergoing high risk non-cardiac surgery up to 1 year following normal stress echo, MPI SPECT, cardiac PET, coronary computed tomography angiography (CCTA), cardiac catheterization.
Exercise stress testing would not be expected to be performed with signs and symptoms of cardiopulmonary instability and generally-recognized contraindications (e.g., unstable angina, LV dysfunction).
For patients with an abnormal resting ECG because of left bundle branch block, pre-excitation syndrome, left ventricular hypertrophy (LVH) or digoxin therapy, an exercise or pharmacological imaging study should be considered because the accuracy of the exercise ECG in detecting provocable ischemia is reduced.
Cardiovascular stress testing may be performed in conjunction with additional cardiac diagnostic tests including echocardiography and nuclear cardiac imaging. It is expected that only the most appropriate test(s) necessary will be performed and billed to Medicare. The routine and repetitive monitoring of such patients beyond the first cardiac stress test, in the absence of a documented change in condition (i.e. new symptoms or progression of existing symptoms) is not considered medically necessary.
Exercise testing should be supervised by an appropriately trained physician. Exercise testing in selected patients can be performed safely by properly trained nurses, exercise physiologists, physician assistants, physical therapists, or medical technicians working directly under the supervision of a physician, who should be in the immediate vicinity and available for emergencies.
Given the limitations of uptake, low photon energy and distribution, the perfusion imaging codes are not generally covered on the same date of service.
Patients with initial abnormal test results have variable pre-test probabilities for adverse events, and the need and timing of follow up nuclear imaging studies must be justified in the medical record.
All cardiovascular nuclear tests must be referred by a physician or a qualified non-physician.
All cardiovascular nuclear tests must be performed under the general supervision of a physician. The Medicare Carriers Manual describes general supervision as applicable when a procedure is furnished under the physician’s overall direction and control, but the physician’s presence is not required during the performance of the procedure. Under general supervision guidelines, the training of the nonphysician personnel who actually perform the exercise procedure and the maintenance of the necessary equipment and supplies are the continuing responsibility of the supervising physician.
Neither exercise testing nor radiologic imaging is indicated in the initial months after PCI without specific symptoms (i.e., chest pain, ECG changes etc.).
Cardiovascular stress testing (with or without imaging) and cardiac imaging studies are not indicated if the results will not affect patient management decisions. If a decision to perform cardiac catheterization or other angiography has already been made, there is often no need for cardiovascular stress testing and/or cardiac imaging testing.
In the case of myocardial viability, the FDG positron emission tomography (PET) may be used following a SPECT that was found to be inconclusive. However, SPECT may not be used following an inconclusive FDG PET performed to evaluate myocardial viability.

In summary, the choice of stress testing modality depends on many factors such as the patient’s ability to exercise, the resting ECG, the clinical indication for performing the test, the patient’s body habitus, and history of prior revascularization.
The following are considered medically necessary for either the stress echo or SPECT MPI:
1. New, recurrent, or worsening cardiac symptoms AND any of the following:
Physical inability to perform a maximum exercise workload
A history of CAD based on a prior anatomic evaluation of the coronary arteries OR a history of CABG or PCI
Syncope (i.e., no prodromal symptoms, not near syncope) in patient with high likelihood of CAD
Evidence or high suspicion of ventricular tachycardia
Age 50 years or greater and known diabetes mellitus
New or previously unrecognized uninterpretable ECG
Poorly controlled hypertension, generally, above 180 mm/Hg systolic, if the provider feels strongly that CAD needs evaluation prior to BP being controlled
ECG is uninterpretable for ischemia due to any one of the following:
o Complete Left Bundle Branch Block (right bundle branch does not render ECG uninterpretable for ischemia)
o Ventricular paced rhythm
o Pre-excitation pattern such as Wolff-Parkinson-White
o > 0.5 mm ST segment depression (NOT nonspecific ST/T wave changes)
o LVH with repolarization abnormalities, also called LVH with strain (NOT without repolarization abnormalities or by voltage criteria)
o T wave inversion in the inferior and/or lateral leads (leads II, AVF, V5, or V6)
o Patient on digitalis preparation
Worsening or continuing symptoms in a patient who had a normal or submaximal exercise stress test and there is suspicion of a false negative result
Patients with recent equivocal or borderline testing where ischemia remains a concern
Patients on beta blocker, calcium channel blocker, and/or antiarrhythmic medication when the documentation supports that an adequate workload may not be attainable to enable a fully diagnostic exercise study
History of false positive exercise stress test (e.g., one that is abnormal, but the abnormality does not appear to be due to macrovascular CAD)
High pretest probability of CAD (assuming emergency evaluation and/or prompt coronary angiography not previously implemented)
2. Patients without clear cardiac symptoms in the presence of an elevated cardiac troponin
3. Routine study > 3 years after a PCI (stent) without cardiac symptoms and absent an evaluation for CAD within the past 2 years (stress echo, MPI SPECT, cardiac PET, coronary computed tomography angiography (CCTA), cardiac catheterization)
4. Routine study > 5 years after CABG without cardiac symptoms in a patient who has not had an evaluation for CAD within the past 2 years (stress echo, MPI SPECT, cardiac PET, coronary computed tomography angiography (CCTA), cardiac catheterization)
5. Every 2 years in patients with documentation of previous “silent ischemia” (and diabetes mellitus) evident on previous MPI but not evident on previous exercise stress test
6. To assess for CAD in a patient with unexplained or drug-induced intraventricular condition disturbances
7. Prior anatomic imaging study (coronary angiogram or CCTA) to assess recently demonstrated coronary stenosis of uncertain functional significance in a major coronary branch can have one stress test with imaging
8. Established CAD in a patient who had an acute coronary syndrome (ACS) (ST segment elevation MI (STEMI), Non–ST segment elevation MI (NSTEMI), unstable angina) event within the past 90 days provided that the patient has not undergone coronary angiography at the time of the acute event and is currently clinically stable
9. Evaluating new, recurrent, or worsening left ventricular dysfunction/CHF
10. Assessing myocardial viability in patients with significant ischemic ventricular dysfunction (suspected hibernating myocardium) and persistent symptoms or heart failure such that revascularization would be considered
11. Pre-operative cardiac evaluation in patients undergoing non-cardiac surgery
-Intermediate risk surgery (cardiac risk 1-5%) one or more cardiac risk factor(s) and inability to exercise adequately
-high risk surgery (> 5% cardiac risk)
12. Asymptomatic patients with uninterpretable ECG and no evaluation for cardiac disease in the past 3 years
13. Planned cardiac or other solid-organ transplant if no cardiac evaluation has been performed within the past year
14. Patients to be treated with interleukin 2 (a pro-atherogenic agent) for various malignant disorders, etc.
15. Patients with disease conditions associated with CAD (e.g., DM, AAA, PVD, carotid artery disease, CRF) and no documented evaluation was performed within the preceding 2 years
16. Stress echocardiography will be considered reasonable and necessary for the evaluation of valvular heart disease and detection and management of occult pulmonary hypertension.
The following are considered medically necessary for cardiac PET:
1. For the evaluation of coronary artery disease for perfusion of the heart via myocardial perfusion imaging, PET scans using either FDA-approved radiopharmaceutical Rubidium 82 (RB-82) or Ammonia N-13 when performed at rest or with pharmacological stress used for noninvasive imaging of the perfusion of the heart for the diagnosis and management of patients with known or suspected coronary artery disease, provided the following requirements are met:
a. The PET scan (whether at rest alone or rest with stress) is performed in place of, but not in addition to, a single photon emission computed tomography (SPECT) in persons with conditions that may cause attenuation problems with SPECT, e.g., obesity (BMI greater than or equal to 35), large breasts, breast implants, left mastectomy, chest wall deformity, pleural or pericardial effusion;
b. The PET scan (whether at rest alone or rest with stress) is used following a SPECT that was found to be inconclusive. In these cases, the PET scan must have been considered necessary in order to determine what medical or surgical intervention is required to treat the patient. (For purposes of this requirement, an inconclusive test is a test(s) whose results are equivocal, technically uninterpretable, or discordant with a patient’s other clinical data and must be documented in the beneficiary’s file.)
For cardiac perfusion studies, patient selection criteria for PET scans involve an individual assessment of the pretest probability of CAD, based both on patient symptoms and risk factors:
Patients at low risk for CAD may be adequately evaluated with exercise electrocardiography.
Patients at high risk for CAD will typically not benefit from non-invasive assessment of myocardial perfusion since a negative test will not alter disease probability sufficiently to avoid invasive angiography.
Myocardial perfusion imaging is potentially beneficial for patients at intermediate risk of CAD (approximately 25% to 75% disease prevalence).
The risk can be estimated using the patient’s age, sex, and chest pain quality. The range for intermediate risk can vary.
The following summarizes a characterization for patient populations at intermediate risk for CAD:
Chest pain with all of the following characteristics:
• Substernal chest discomfort with characteristic quality and duration, and provoked by exertion or emotional stress, and relieved by rest or nitroglycerin
• Men ages 30-39
• Women ages 30-60
• Chest pain that lacks one of the characteristics of typical angina
• Men ages 30-70
• Women ages 50 years and older
Non-anginal Chest Pain:
• Chest pain that meets one or none of the typical angina characteristics
• Men ages 50 years and older
• Women ages 60 years and older
2. For the determination of myocardial viability, using Fluorodeoxyglucose (F-18 FDG) as a radioactive tracer, when performed as a primary or initial diagnostic study prior to revascularization, or following an inconclusive SPECT. However, if a patient receives an FDG PET study with inconclusive results, a follow up SPECT test is not covered. The identification of patients with partial loss of heart muscle movement or hibernating myocardium is important in selecting candidates with compromised ventricular function to determine appropriateness for revascularization. Diagnostic tests such as FDG PET distinguish between dysfunctional but viable myocardial tissue and scar tissue in order to affect management decisions in patients with ischemic cardiomyopathy and left ventricular dysfunction.
3. For the determination of cardiac involvement, using Fluorodeoxyglucose (F-18 FDG), to diagnose cardiac sarcoidosis in patients who are unable to undergo magnetic resonance imaging (MRI) scanning. Examples of patients who are unable to undergo MRI include, but are not limited to, patients with pacemakers, automatic implantable cardioverter defibrillators (AICDs), or other metal implants.
