What 36556 covers

This service covers placement of a non-tunneled catheter into a central vein for access such as infusion of medications or fluids, hemodynamic monitoring, or treatment when peripheral access is inadequate. It is commonly performed by a physician or other qualified practitioner in a hospital, intensive care unit, emergency department, or procedural setting. The patient must be at least 5 years old, and the catheter must be centrally inserted and non-tunneled; a peripherally inserted central catheter or a tunneled catheter is a different service.

Report the code for the insertion, not for a later exchange or removal. The record should identify the indication, patient age, access site, and catheter placement. Ultrasound guidance may be separately reported when its requirements are met and documented. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery 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.

36556 billing questions

How does 36556 differ from 36555?

Both cover insertion of a non-tunneled, centrally inserted catheter. Use 36556 for patients age 5 years or older and 36555 for children younger than 5.

When is 36558 more appropriate?

36558 describes insertion of a tunneled central venous catheter in a patient age 5 years or older. Use 36556 when the catheter is non-tunneled.

Can ultrasound guidance be reported separately?

CPT 76937 may be reported separately when the required ultrasound guidance service is performed and the documentation supports it.

Should modifier 50 be appended for access on both sides?

No. Medicare's bilateral adjustment does not apply to 36556, and modifier 50 is inappropriate.

Is same-day postoperative care separately payable?

No. The 0-day global period includes same-day preoperative and postoperative care.

Can an assistant or co-surgeon be paid for 36556?

Medicare does not pay an assistant at surgery for this service because of a statutory restriction. Co-surgeons and team surgery are not permitted.

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.
