Claims should include supporting clinical data: relevant medical history, physical examination findings, other laboratory studies, chest x-ray, and electrocardiography to demonstrate that BNP testing is being used in conjunction with standard diagnostics.
For risk stratification after ischemic events, documentation should indicate timing of BNP measurement relative to onset of ischemic symptoms (obtained in the first few days).
Either total BNP assays or N-terminal (NT-proBNP) assays are acceptable and the assay type should be documented on the claim or in the medical record.
All CCTA studies must be ordered by the treating physician or qualified non-physician practitioner who will use the results in patient management and must be performed under the direct supervision of a physician.

BNP testing is reasonable and necessary, when used with other medical data, to distinguish a cardiac cause of acute dyspnea from pulmonary or other non-cardiac causes.
BNP testing may be used to distinguish decompensated congestive heart failure from exacerbation of chronic obstructive pulmonary disease in a symptomatic patient with both chronic CHF and COPD.
BNP testing obtained in the first few days after onset of ischemic symptoms may be used for risk stratification (risk of death, myocardial infarction, or CHF) among patients with acute coronary syndrome, including myocardial infarction (with or without ST changes) and unstable angina.
CCTA may be used to reliably rule out significant coronary artery disease (CAD) in patients with low to intermediate pre-test probability of CAD as an alternative to an imaging stress test.
CCTA may be used in a patient presenting with chest pain syndrome when the clinician has a high degree of suspicion that CAD is high on the differential diagnosis.
CCTA may be used to facilitate management in select patients who have an equivocal stress test or stress imaging result.
