What 36597 covers

This procedure moves a previously placed central venous catheter back into an appropriate position under fluoroscopic guidance. A typical reason is a catheter tip that has migrated into the internal jugular vein. An interventional radiologist or other clinician performing vascular access procedures manipulates the existing catheter while viewing its position, rather than inserting a new one. The service is commonly performed in an interventional radiology suite.

Report 36597 when the record documents that the existing catheter was actually repositioned, including its position before and after manipulation. An injection performed only to evaluate the device is a different service; replacing the catheter also calls for a different code. CMS assigns a 0-day global period, so routine preoperative and postoperative care on the procedure date is included. If multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and others at 50%. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

36597 billing questions

How is repositioning different from evaluating the catheter under fluoroscopy?

Report 36597 when the existing catheter is moved to correct its position. If the clinician injects contrast to evaluate the device without repositioning it, consider 36598 instead.

What if the catheter is removed and replaced?

Replacement is different from repositioning the retained catheter. Select the replacement code for the type of central venous access device and the work performed.

What documentation supports 36597?

The procedure note should identify the existing catheter, describe the malposition and the manipulation performed, and record the resulting position.

Can fluoroscopic guidance or routine same-day care be billed separately?

Fluoroscopic guidance is part of this repositioning procedure. CMS also includes routine preoperative and postoperative care on the procedure date in its 0-day global period.

How do multiple procedures and surgical-team claims affect payment?

In a same-session multiple-procedure claim, CMS pays the highest-valued procedure in full and others at 50%. Modifier 50 is inappropriate; CMS does not pay an assistant at surgery and does not permit co-surgeons or team surgery for 36597.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
