Echocardiograms performed as part of the CAMZYOS REMS program are covered when billed with modifier KX and all REMS program requirements are met for patients with NYHA Class II–III obstructive hypertrophic cardiomyopathy (I42.1).
An ECG is covered when the result is relevant to the management, diagnosis, or treatment of the patient.
