Cardiology Medical Billing & Revenue Cycle ManagementCardiology Medical Billing & Revenue Cycle Management

What makes cardiology billing difficult?

Many cardiac tests split into a professional component (the interpretation) and a technical component (the equipment and staff), and who may bill each part depends on where the test was performed. Advanced imaging usually needs authorization first, and patients often have a visit and a procedure on the same day. Each of these has its own documentation rules, so one missing detail can hold up the whole claim.

What are the most common cardiology billing pitfalls?

• TC vs 26 component billing. When a cardiologist reads an echo or stress test performed on hospital equipment, the practice bills the professional component with modifier 26 and the facility bills the technical component (TC). Billing the global service for a test you only read leads to denials or overpayments.
• Modifier 25 with same-day procedures. An office visit billed on the same day as a procedure needs a significant, separately identifiable evaluation documented in the note. Modifier 25 should be added only when the record supports it.
• Prior authorization for advanced cardiac imaging. Nuclear stress tests, cardiac CT, cardiac MRI and cardiac PET often need approval first, sometimes through a radiology benefit manager. The approval must match the test and site of service actually performed.
• Device and implant documentation. Pacemaker, defibrillator and loop recorder implants need operative notes with the device details, and device checks and remote monitoring follow their own documentation rules.

What causes cardiology claim denials?

The usual causes are a missing or mismatched imaging authorization, a component modifier that doesn't match the site of service, and a diagnosis that doesn't meet the payer's coverage policy for the test. Bundling edits also deny services that are billed together without a modifier supported by the documentation.

How do you handle eligibility and prior authorization for cardiology?

We verify coverage and benefits before the visit and check whether the plan routes imaging through a benefit manager. For tests that need approval, we request it before scheduling and record the approved code, the authorization number and its expiry, so a changed test order is caught before the claim goes out.

How are cardiology claims coded and submitted?

Each claim is checked for the right test code, the professional or technical component modifier, the place of service and a diagnosis that supports medical necessity. Same-day visits and procedures are reviewed for modifier 25 before submission, and claims go out with the authorization number the payer expects.

How do you handle payment posting and AR follow-up for cardiology?

Payments are posted line by line from ERAs and EOBs, so an underpaid component or a bundled test shows up instead of disappearing into a lump sum. Unpaid and denied claims are worked by payer and filing deadline, with corrected claims or appeals sent with the records the payer asked for.

Do you handle credentialing and enrollment for cardiologists?

Yes. We help enroll cardiologists with Medicare and commercial plans and keep enrollment details current, so new physicians can bill from their start date. Some payers also require imaging accreditation before they pay the technical component of advanced imaging, which is worth checking during enrollment.

How does onboarding work for a cardiology practice?

Most practices are onboarded within two to four weeks, depending on the size of the practice and how quickly payer and system access is set up. We work within your existing practice management system, so your physicians and front desk keep the tools they use today. See all the specialties we support.

Frequently asked questions

What is the difference between the professional and technical component in cardiology?

The professional component is the physician's interpretation and report, billed with modifier 26. The technical component covers the equipment, supplies and staff that performed the test, billed with modifier TC. When one practice performs and reads the test on its own equipment, it bills the global service with no modifier. When a hospital owns the equipment, the cardiologist bills only the professional component.

When should modifier 25 be used on a cardiology claim?

Modifier 25 goes on an office visit billed on the same day as a procedure, but only when the visit was significant and separately identifiable from the procedure. The note has to show work beyond the usual evaluation that comes with the procedure itself. Adding it to every same-day visit invites audits and denials, so we check the documentation before the claim is sent.

Which cardiology tests usually need prior authorization?

Advanced cardiac imaging is the most common: nuclear stress tests, cardiac CT, cardiac MRI and cardiac PET. Many commercial and Medicare Advantage plans manage these through a radiology benefit manager. Requirements differ by plan, so we check each patient's plan before scheduling and make sure the approval matches the test and location that are actually billed.

Why do pacemaker and defibrillator claims get denied?

Device claims are denied when the operative note lacks the device details, when the diagnosis doesn't meet the payer's coverage criteria, or when device checks and remote monitoring are billed without the documentation those services require. We review the procedure note and coverage requirements before submission, and follow up with the payer on any device claim that comes back unpaid.

Can you work with our existing cardiology billing system?

Yes. We work within your existing practice management and EHR systems, so your physicians and staff keep their current workflow. Most practices are onboarded within two to four weeks, depending on practice size and how quickly payer and system access is set up. During onboarding we review open AR and recent denials so follow-up starts with the claims at risk first.
