I'm not really clear on the thinking on this question. If someone has Cigna, for example, you need to look at Cigna's policy on it and see when it is covered. Someone else's coverage isn't going to help you for that patient.
For example, Evicore Health states:
78803 Radiopharmaceutical localization of tumor or distribution of radiopharmaceutical agent(s); tomographiic (SPECT). (Non-SPECT is 78800)
A9538 for the radiopharmaceutical
Indications may include:
Individuals with heart failure and unexplained increase in left ventricular wall thickness.
African-Americans over the age of 60 years with heart failure, unexplained or with increased left ventricular wall thickness (>12 mm).
Individuals over the age of 60 years with unexplained heart failure with preserved ejection fraction.
Individuals, especially elderly males, with unexplained neuropathy, bilateral carpal tunnel syndrome or atrial arrhythmias in the absence of usual risk factors, and signs/symptoms of heart failure.
Evaluation of cardiac involvement in individuals with known or suspected familial amyloidosis.
Diagnosis of cardiac ATTR in individuals with CMR or echocardiography consistent with cardiac amyloidosis.
Individuals with suspected cardiac ATTR amyloidosis and contraindications to CMR such as renal insufficiency or an implantable cardiac device.
