2025 CPT code 93593
Right heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone; normal native connections.
Modifiers may be applicable to this code to further specify the circumstances of the procedure, such as increased procedural services (modifier 22) or reduced services (modifier 52).
Medical necessity is established by the presence of a congenital heart defect requiring assessment of right heart function, blood flow, and oxygen saturation levels.The information obtained guides treatment decisions, such as surgical intervention or medical management.
After appropriate preparation and anesthesia, a small incision is made in the arm or groin to access a blood vessel. Using ultrasound and/or fluoroscopy for guidance, a catheter is advanced through the blood vessels to the right side of the heart. Blood samples are obtained, and other measurements may be taken as needed. The catheter is then removed, and pressure is applied to the incision site.
In simple words: For a patient born with one or more heart defects and normal blood flow pathways, the doctor guides a thin tube (catheter) through blood vessels into the right side of the heart. This allows the doctor to collect blood samples and perform other measurements to assess heart function.
This code describes a right heart catheterization procedure performed for congenital heart defects in patients with normal native connections. It includes imaging guidance used to maneuver the catheter to the targeted area within the heart.Normal native connections indicate that blood flows through the heart and great vessels in the typical anatomical pathway. The procedure involves inserting a catheter into the right side of the heart to obtain blood samples for gas measurement and potentially other assessments, like Fick cardiac output measurements.
Example 1: A newborn with an atrial septal defect (a hole between the heart's upper chambers) undergoes right heart catheterization to assess the defect's impact on blood flow and oxygen saturation levels., A child with a ventricular septal defect (a hole between the heart's lower chambers) undergoes this procedure to measure the pressure difference between the ventricles and evaluate cardiac output., A pediatric patient with a patent ductus arteriosus (a persistent opening between two major blood vessels) undergoes right heart catheterization to determine the size and location of the opening and its effect on circulation.
Documentation should include the medical necessity for the procedure, details of the catheterization process, including imaging guidance used, blood gas measurements, any additional hemodynamic assessments performed, and the patient's response to the procedure. Supporting clinical findings related to the congenital heart defect diagnosis should also be included.
