What 36510 covers

A clinician places a catheter through the umbilical vein of a newborn to obtain vascular access for diagnosis or treatment. The service is typically performed in a hospital newborn or neonatal intensive care setting, such as when a newborn needs access for medication, fluids, blood sampling, or other indicated therapy. The report should identify the newborn, the umbilical venous route, the reason for catheterization, and the procedure performed.

This code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures, including this one when lower-valued, are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity; 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.

36510 billing questions

When should this code be chosen instead of a PICC insertion code?

Use this code when the catheter is placed through a newborn’s umbilical vein. PICC codes describe peripherally inserted central catheters, not umbilical access.

Does the 0-day global period include same-day care?

Yes. Same-day preoperative and postoperative care is included in the 0-day global period.

Should modifier 50 be appended for catheterization on both sides?

No. Modifier 50 is inappropriate for this service.

How is this code affected when other procedures occur in the same session?

The highest-valued procedure is paid in full; other procedures are subject to the standard 50% multiple-procedure reduction.

When is assistant-at-surgery payment allowed?

Only when the record documents medical necessity for the assistant. 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.
