Cardiology medical billing is a complex and time-consuming process aimed at providing particular care to patients. Due to the complexity, it is advisable that healthcare practitioners should opt for medical billing services which can significantly reduce a major burden for healthcare practitioners.
When you outsource your billing to any professional cardiology coding and billing company, they take up the responsibility of getting your claim reimbursed. From original operation to denial management, everything is taken care of by the company.
Healthcare organizations specializing in medical billing can create strategies for your technical coding and procedures which will maximize the value for your money.
Cardiology deals with health issues and diagnostics related to our heart and circulatory systems. Medical billers use Current Procedural Terminology (CPT) codes to maintain and submit the claims for the services rendered to the patients. These codes are five-digit numbers used to define various types of medical care. Each code is different from another and reflects a particular service.
In this blog we will learn about the most common cardiology CPT codes which are used to accurately describe the services and treatments rendered to the patient.
Common Cardiology CPT Codes

CPT Code 33945- Heart Transplantation
This code defines the complex zone of heart transplantation. It covers the entire process from removal of heart through Cardiectomy to transplanting a new heart into the recipient's body. This code is the indication of marvels of modern medicine and the arrangements for such life-altering procedures.
CPT Code 33935- Donor Cardiectomy
This code defines the intricate movements of donor Cardiectomy. It encapsulates the delicate arrangements involved in bidding farewell to the donor’s heart and preparing it for the new body. It's like taking life out of a body and putting it into another one.
CPT Code 33533- Coronary Artery Bypass
This code showcases the process of a coronary artery bypass using four venous grafts. It is a very intricate process which involves great precision. In this process the heart’s circulation is redirected to ensure a harmonious flow of life-giving blood.
CPT Code 93458- Coronary Angiography
This code directs us towards the background working of coronary angiography. This includes imaging and intravascular ultrasound to understand the delicate architecture of the heart. This code also helps in planning the diagnosis.
CPT Code 92920- Balloon Angioplasty
This code orchestrates the working of narrow arteries through balloon angioplasty. It takes care of the blood flow through the heart which ensures that the heart’s rhythm is completely in sync with the body.
CPT Code 33206- Atrial Pacemaker
This code determines if there is a need for insertion or replacement of a permanent pacemaker. This code ensures that the heart’s rhythm is maintained for a healthy life ahead.
CPT Code 93306- Echocardiogram for Real Time Imaging
This code represents the echocardiography procedure which is used to take a look inside your chest. This process captures your heart’s movement with M-mode, Doppler Imaging and a symphony of colors. It is a visual journey of the beating heart which provides crucial diagnostic insights.
CPT Code 93015- Cardiovascular Stress Test
This code is used to represent the cardiovascular functioning during exercise. With continuous electrocardiographic monitoring it checks the response of your heart during a thrilling activity. It overlooks cardiac health under stress.
CPT Code 93224- Holter Monitoring
This code demonstrates the complexities of Holter monitoring. It is a dynamic process which records the heart’s performance over 48 hours. It has a very important role in cardiology with providing an extensive snapshot of the heart’s rhythm. This information is very helpful to identify the irregularities. This code signifies electrocardiography data which offers great insights into the patient’s cardiac health.
CPT Code 93010
This code represents the electrocardiogram which is a widely used test in Cardiology. An EKG measures the electrical activity of the heart and helps providers find the symptoms of heart disease.
In this process electrodes are placed on the patient’s chest, limbs, and torso while recording the heart’s electrical signals.
CPT Code 93010 is used to record the technical component of an EKG. It includes the performance of the test, and the equipment used. When you use this code, make sure you do accurate documentation of the procedure including the equipment used and the test performance.
CPT Code 93000
CPT code 93000 depicts the electrocardiogram interpretation report. This code focuses on the professional component of EKG. It includes the interpretation and analysis of the EKG results by a qualified medical professional.
This code is important for accurately documenting the healthcare provider’s expertise in evaluating a patient’s cardiac health. This helps the provider create a diagnosis or treatment plan based on the findings.
CPT Code 93005
This code is quite similar to the CPT code 93005, but it encloses the entire EKG procedure. It includes technical as well as professional components.
This code is used when a medical practice performs EKG and its interpretation. It helps you streamline the billing process by combining the services in a single code. It simplifies and ensures accurate reimbursement and documentation of the entire EKG procedure.
CPT Code 93306
This code refers to echocardiography, a non-invasive imaging technique used to determine the structure and function of the heart. It uses sound waves to create real-time images of the heart’s chambers, valves, and blood flow patterns.
Echocardiography is an essential tool for treating a variety of heart conditions such as congenital heart defects, heart valve abnormalities, and heart failure.
It involves the technical and professional components of the echocardiography procedure.
CPT Code 93798
This code represents the physician’s interpretation of cardiovascular stress testing. These tests are performed to evaluate one's heart response to physical exertion. It is used to identify any hidden heart conditions which may not appear during normal tests.
This code includes the physician’s analysis of the results and the generation of a detailed report. It helps in the diagnosis and management of cardiovascular diseases.
CPT Code 93325
This code denotes a specialized technique which determines the blood flow through the heart and blood vessels using ultrasound technology. It provides great insights on the speed, direction, and volume of the blood flow which helps in the diagnosis of conditions such as blood clots, valve disfunction, and cardiac defects.
Doppler echocardiography plays an important role in guiding the treatment decisions and monitoring the effectiveness of interventions.
CPT Code 93296
This code denotes the interrogation and programming of a pacemaker or implantable cardioverter-defibrillator (ICD). Pacemakers and ICDs are devices planted in the chest to find uneven heart rhythms. This can be very helpful in prevention of life-threatening arrhythmias.
This interrogation involves retrieving data from the device and programming the device’s settings to optimize its performance for individual patients.
CPT Code 93015
This code defines the cardiovascular stress test which is also known as stress testing. The process involves monitoring a patient’s heart rate, blood pressure, and electrocardiogram while they perform some physical exercise.
Stress testing also helps in determining efficient exercises for heart patients.
CPT Code 93018
This code represents the rhythm EKG, a specialized type of electrocardiogram used to monitor the heart’s electrical activity for 24 hours or more. This involves wearing a portable EKG device often called a ‘Holter Monitor’ which records the heart’s electrical signals regularly.
Rhythm EKGs are very useful for capturing transient arrhythmias or symptoms that occur not so regularly. This aids the diagnosis and management of various cardiac rhythm disorders.
CPT Codes 93017
This code relates to cardiovascular stress testing which uses pharmacological agents rather than exercise. This type of stress test is often performed when a patient cannot do enough exercise due to any limitation. A pharmacological stress test replicates the exact effects on the patient’s heart which would be there after an exercise session.
This is done by administering medications which increase heart rate and blood flow. Medical practices can evaluate the heart’s response and identify any hidden cardiac issues.
Bottomline
These significant CPT codes come in handy when healthcare providers need to communicate about the services they provide to the patients. This plays an important role in maintaining and improving patient care quality.
