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

What 33840 covers

The surgeon removes the narrowed segment of the aorta and reconnects the remaining ends directly, creating an end-to-end anastomosis. This operation treats aortic coarctation, usually a congenital narrowing, and is typically performed by a congenital cardiac or cardiothoracic surgeon in a hospital operating room. Patients are often infants or children, though coarctation may be repaired later in life.

Choose this code when the operative report supports excision of the coarctation and direct anastomosis, rather than reconstruction with an interposition graft or patch. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted, and modifier 50 is inappropriate for this anatomy.

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.
