Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.

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.
