2025 CPT code 93594
(Active) Effective Date: N/A Medicine/Cardiovascular - Cardiac Catheterization for Congenital Heart Defects Feed
Right heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone; abnormal native connections.
Modifiers may be applicable to indicate specific circumstances of the procedure, such as increased procedural services (22), reduced services (52), or distinct procedural service (59).
Medical necessity for 93594 is established by the need to evaluate a congenital heart defect with abnormal native connections.The specific clinical indication should be documented, such as pre-operative assessment, evaluation of cardiac function, or assessment of treatment response.
The physician is responsible for the entire procedure, including access, catheter placement, pressure measurements, blood sampling, and interpretation of results.
In simple words: This procedure is used to diagnose and assess congenital heart defects in patients whose blood doesn't flow normally through the heart. A thin tube (catheter) is inserted through a vein and guided to the right side of the heart using imaging technology.Measurements of pressure and blood samples are taken to evaluate the heart's function. This procedure is specifically for patients with abnormal heart structures and blood vessel connections.
This code represents a right heart catheterization performed for the evaluation of congenital heart defects in patients with abnormal native connections. It includes imaging guidance used by the physician to position the catheter, allowing for pressure measurements and blood gas analysis within the right heart chambers and pulmonary artery.Abnormal native connections refer to variations in blood flow pathways through the heart and great vessels, such as those seen in cyanotic congenital heart defects, single ventricle anatomy, and transposition of the great arteries.
Example 1: A newborn with transposition of the great arteries undergoes right heart catheterization to assess pressures and blood flow before surgery., A child with a single ventricle heart defect requires right heart catheterization to evaluate the function of the Fontan circulation., A teenager with Tetralogy of Fallot undergoes right heart catheterization to measure pressures and oxygen saturation before a planned intervention.
Documentation should include a detailed operative report describing the procedure, including catheter placement, pressure measurements, oxygen saturations, blood gas analysis, any complications, and interpretation of the findings. The specific congenital heart defect being evaluated must be clearly documented. Any additional procedures, such as angiography or biopsy, should be documented separately.
