In simple words: The doctor inserts a thin tube (catheter) into a major vein in the body (like the one near the kidney or in the neck) to check for problems or give medicine.

This CPT code encompasses the selective catheter placement into a first-order branch vein, such as the renal vein or jugular vein.The procedure involves the introduction of a catheter into the vein, and may include the use of contrast media for visualization.It is typically performed for diagnostic or therapeutic purposes, such as administering medications or obtaining samples.

Example 1: A patient presents with suspected renal vein thrombosis.The physician performs a selective catheterization of the renal vein to administer thrombolytic therapy., A patient with central venous catheter malfunction requires the placement of a new catheter in the internal jugular vein for intravenous medication delivery., A patient with suspected superior vena cava syndrome undergoes a venogram of the superior vena cava and its tributaries.This involves selective catheterization of multiple vessels in order to adequately visualize the venous anatomy.

Detailed history and physical examination,informed consent,pre-procedure imaging (if performed),details of the catheterization procedure (including vessel accessed, catheter type, contrast media used, and any complications),post-procedure imaging (if performed), and post-procedure monitoring data.

** Accurate coding requires careful consideration of the specific vessels accessed and the complexity of the procedure.Documentation must clearly support the services reported.Always consult the most current CPT manual and NCCI edits for proper coding and billing practices.
