(Active) Effective Date: N/A Revision Date: N/A Cardiovascular Procedure - Cardiac Catheterization Procedures Medicine Services and Procedures > Cardiovascular Procedures > Cardiac Catheterization Procedures Feed
Right heart catheterization, including oxygen saturation and cardiac output measurements when performed.
Modifiers 26 (professional component) and TC (technical component) are applicable. Other modifiers may be used as appropriate based on circumstances of the procedure. Consult CPT guidelines for details.
Medical necessity is established based on clinical presentation (symptoms of heart failure, shock, etc.), presence of risk factors, and need for assessment of hemodynamics to guide appropriate medical or surgical management.Payor-specific guidelines should also be considered.
The physician is responsible for inserting and positioning the catheter, obtaining hemodynamic measurements (pressure and oxygen saturation), interpreting the results, and providing a report.In some settings, technical components may be performed by other qualified personnel.

- Cardiac Catheterization and Associated Procedures
In simple words: A thin tube is inserted into a vein in your neck or leg to measure blood oxygen levels and the amount of blood your heart pumps.The tube is guided into the heart and lungs using X-rays, taking measurements along the way. The tube is either left in place for monitoring or removed.
This procedure involves percutaneous venous access (internal jugular, subclavian, or femoral vein) under fluoroscopic guidance.Oxygen saturation measurements are obtained to assess cardiac output.The catheter is advanced through the right atrium, tricuspid valve, right ventricle, pulmonary valve, and into the pulmonary artery.Pressure measurements are taken within the cardiac chambers and pulmonary artery.The catheter may be left in place for monitoring or removed after hemostasis is achieved.
Example 1: A patient presents with suspected heart failure.Right heart catheterization is performed to assess cardiac output, pulmonary artery pressures, and to rule out other causes of the symptoms., A patient post-cardiac surgery exhibits signs of low cardiac output.Right heart catheterization is used for hemodynamic monitoring and to guide treatment., A patient with pulmonary hypertension undergoes right heart catheterization to assess the severity of the disease and to monitor response to therapy.
Detailed patient history and physical examination, indications for the procedure, hemodynamic measurements (pressures, oxygen saturations, cardiac output), any complications encountered, and post-procedure course.
