Frequently Asked Questions
Efficient cardiology billing is crucial to providing high-quality cardiac care. However, cardiologists have their concerns regarding the billing process. Below we have answered some questions that they frequently ask. Whether you’re practicing cardiology individually or affiliated with a hospital, these will effectively clear your confusion. Let’s have a look:
1) What is the billing code range for cardiology procedures?
Cardiovascular procedures are most commonly billed with CPT codes in the 92920-93799 range, covering therapeutic services, imaging, and monitoring — each code matched to documented procedure details for clean claims.
2) Which modifiers are commonly used in cardiology billing?
The most common are modifier -26 for the professional component of diagnostic tests, -TC for the technical component, and -59 for distinct procedural services performed on the same day. Correct modifier use is one of the biggest levers for reducing cardiology denials.
