Cardiology billing for diagnostics, procedures and imaging
Billing for cardiology practices: ECGs, echocardiograms, stress tests and more.
How cardiology billing works
Most cardiology diagnostics have a professional component (modifier 26) and a technical component (TC). Who owns the equipment and where the test was done decide which part you bill. Nuclear imaging and many echocardiograms also need prior authorization through radiology benefit managers.
