Top 5 Cardiology Billing Companies
Cardiology is one of the specialties in U.S. healthcare billing that faces a high number of claim denials. Payers have increased prior authorization requirements for high-value cardiology procedures, including cardiac catheterization, nuclear stress testing, echocardiography, and electrophysiology studies. These requirements are growing faster than the documentation processes used by many physician groups.
When a cardiology practice works with a generalist billing company, revenue can be affected in three main areas: modifier errors on bundled procedure codes, prior authorization denials when payer-required pre-certification is missing, and gaps in medical necessity documentation that can lead to post-payment audits.
Cardiology CPT codes, including 93000-93799 for diagnostic procedures and 92920-92998 for interventional procedures, require coders with specific cardiology knowledge. They must understand the difference between technical component and professional component billing, global period rules for follow-up visits after procedures, and payer-specific bundling edits. These rules can vary significantly between Medicare, Medicare Advantage, and commercial insurance carriers.
This ranking reviews 5 billing companies based specifically on their cardiology RCM performance rather than their general outpatient billing capabilities applied to cardiology codes.

CareCloud
CareCloud’s billing infrastructure is built mainly for general outpatient claim volumes. Cardiology practices considering CareCloud should verify that their assigned billing staff have cardiology coding certification. The platform supports standard E/M and diagnostic ECG billing. However, interventional cardiology and electrophysiology procedure billing requires specialty knowledge beyond CareCloud’s standard services.
Kareo / Tebra
Kareo/Tebra is designed mainly for small independent practices. Cardiology practices that handle standard diagnostic volumes and have a simple commercial payer mix can work effectively within the Kareo platform. However, complex and high-value interventional cardiology billing, including cardiac catheterization, transcatheter valve procedures, and EP ablations, requires deeper RCM expertise than the Kareo platform is designed to provide.
AdvancedMD
AdvancedMD’s RCM service layer does not provide in-house medical coding. Cardiology practices that use AdvancedMD and depend on its billing service for CPT accuracy on complex interventional procedures may face the same risks found in other complex specialties. Coding decisions can depend heavily on the quality of provider documentation instead of active optimization by specialty-trained coders.
Athenahealth
Athenahealth’s network-based payer intelligence provides cardiology-related coding updates and information about prior authorization requirement changes as major commercial carriers publish them. For cardiology practices using the athenaOne platform with standard diagnostic procedure volumes, its network claims engine can help reduce modifier errors and LCD compliance issues.
However, practices with a high volume of interventional cardiology procedures, such as cardiac catheterization labs and electrophysiology labs, may need deeper coder involvement. The athenaOne billing service layer may not always provide this level of specialty coding support without additional resources.
Questions to Ask a Cardiology Billing Company Before Signing
- What is your NCR for interventional cardiology procedures, including cardiac cath, EP studies, and stress testing?
- How do you track prior authorization requirements for payers that require pre-certification for nuclear perfusion and stress echo?
- Do your coders have AAPC certification and proven cardiology coding experience, particularly with the 92920-92998 and 93000-93799 CPT ranges?
- How do you manage technical versus professional component billing for hospital-based cardiologists using modifier 26?
- What is your appeal win rate for cardiology prior authorization denials, and what documentation do you provide to support medical necessity appeals?

FAQs
What CPT codes does a cardiology billing company need to specialize in?
A cardiology billing company should be experienced in diagnostic cardiology CPT codes (93000-93799) as well as interventional cardiology codes (92920-92998). Important coding areas include technical versus professional component billing (modifier 26/TC), tracking global periods for post-procedure visits, and applying bundling edits correctly for cases involving multiple cardiology procedures.
What prior authorizations are required for cardiology procedures in 2026?
In 2026, common cardiology procedures that may require prior authorization include cardiac catheterization, nuclear myocardial perfusion imaging (stress testing), echocardiography (depending on the payer), electrophysiology studies, and implantable cardiac devices. UnitedHealthcare and Aetna have increased prior authorization requirements for several cardiology services during 2025-2026.
What should a cardiology practice look for in a medical billing company?
A cardiology billing company should have AAPC-certified coders with proven cardiology CPT experience, including 93000-93799 and 92920-92998. It should also offer payer-specific prior authorization tracking for cardiac procedures, technical versus professional component billing expertise, LCD-compliant medical necessity documentation review, and a cardiology denial rate below 8%.
How does global period billing work for cardiology procedures?
The technical component (modifier TC) covers the equipment, facility, and staff costs involved in performing a procedure. The professional component (modifier 26) covers the physician’s interpretation of the procedure or test. Hospital-based cardiologists generally use modifier 26 when the facility bills the technical component separately. Incorrect use of these modifiers can lead to overbilling alerts, underpayments, or post-payment audit risks.
