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

What 36660 covers

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.
