Best Cardiology Billing Companies in the USA

Cardiology is one of the most important medical specialties. For healthcare providers, it is a big source of revenue, yet at the same time, cardiology billing is also a major source of revenue leaks. How? Simply because of claim denials. There are approximately 2,586 active cardiology physician group practices currently operating across the nation.

Each of these practices faces huge challenges in its billing operations. Firstly, because of the huge patient and claim volume, and secondly, due to inefficiency of the in-house billing teams. You might be wondering just how much billing can affect the practices financially. Well, providers collectively lose over $125 billion annually due to billing errors.

That’s why many practices are now preferring to outsource their billing and RCM operations to specialized cardiology billing companies. However, this poses another challenge for practices. How to find the best billing partners for this practice? That’s why we have created this blog on the top 10 cardiology billing companies in the US. So, let’s start with the list.
