Question: The physician removed a non-tunneled central venous catheter through the subclavian vein and replaced it with a tunneled Hickman line for a 50-year-old patient. The physician inserted the new line through the same site. Is there a CPT® code that describes replacing a non-tunneled catheter with a tunneled catheter? Florida Subscriber Answer: In this case, you should report only the placement of the new line with 36558 (Insertion of tunneled centrally inserted central venous catheter, without subcutaneous port or pump; age 5 years or older). Replacement: Although CPT® provides the following two replacement codes for central lines, neither of these codes describes removing a non-tunneled centrally inserted central venous catheter with a tunneled catheter: Removal: CPT® also provides these two codes for removing a central venous catheter: However, these codes do not describe your situation of removing a non-tunneled central venous catheter. Here's why: CPT® does not provide a code for non-tunneled catheter removal because these access lines are intended to be more short term. Removal is included as part of the follow-up to a procedure, or as part of an evaluation and management (E/M) service performed on that date. In your case, removal is included in the new procedure of placing a tunneled central line. That'swhy you should code just the appropriate insertion code - 36558.
