Echocardiography, nuclear stress testing, and cardiac catheterization each carry detailed coding requirements, and advanced imaging almost always needs prior authorization. Medical necessity documentation for these tests is where claims are won or lost.

A cardiology biller should manage the authorization process for imaging as a core function, including tracking approvals and handling peer-to-peers. Practices that leave this to clinical staff end up with scheduling delays and denied tests.

Cardiologists often split time between office, hospital outpatient, and ambulatory surgery settings, and payment differs by place of service. Billing the office rate for a hospital-performed procedure, or vice versa, creates systematic errors.

Your vendor needs to track where each service was performed and apply the correct place-of-service code every time. This sounds administrative, and it is, but the payment differences are significant across a cardiology practice's volume.

Diagnostic tests split into professional and technical components, and cardiology practices need to bill the right component for the right setting. Modifier 26 for the professional component is routine here, and getting the split wrong means billing for work you did not do or missing work you did.

Pacemakers, ICDs, and other device work add implantation coding plus follow-up interrogation billing. Device claims are high-dollar and closely reviewed, so documentation and coding precision matter more than usual.

Use these questions on every sales call. Cardiology billing has expensive failure modes, so verify competence directly.
