About 36660: Newborn umbilical artery catheterization
Reports placement of an arterial catheter through a newborn’s umbilical artery for diagnostic sampling, continuous monitoring, or therapy.
This service places a catheter into a newborn’s umbilical artery, usually in a neonatal intensive care setting. The access can support continuous arterial pressure monitoring, repeated blood sampling such as blood gas testing, or prescribed therapy. A physician or other qualified practitioner with appropriate training performs and documents the placement. The code is specific to the newborn umbilical artery; it does not describe an umbilical venous catheter or a one-time arterial puncture for a blood sample.
Report the service when the catheter is actually placed in the umbilical artery. The procedure note should identify the newborn, arterial route, placement, and clinical purpose. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures 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.

36660 billing questions
How is this different from 36620?
36660 is for catheter placement through a newborn’s umbilical artery. Code 36620 describes percutaneous arterial catheterization by a route other than the umbilical artery.
Can a separate umbilical venous catheter be reported?
An umbilical venous catheter is a different service and uses a venous access code. Document the separate vessel and catheter placement rather than treating venous access as part of 36660.
Does modifier 50 apply when both sides are involved?
No. CMS specifies that bilateral adjustment does not apply and modifier 50 is inappropriate for this code.
Is same-day evaluation and postoperative care separately included?
The 0-day global period includes same-day preoperative and postoperative care. The code reports the catheter placement itself.
How does the multiple-procedure reduction work?
For procedures performed in the same session, CMS pays the highest-valued procedure in full and applies the standard 50% reduction to the others.
What documentation supports an assistant-at-surgery claim?
The record must document the medical necessity of the assistant. CMS does not permit co-surgeon or team-surgery payment for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
