What 33506 covers

A congenital cardiac surgeon uses this operation to correct an anomalous coronary artery origin by mobilizing the vessel and moving its origin to an appropriate aortic location. It is used for selected congenital coronary artery arrangements, including an artery arising from the opposite aortic sinus when the surgeon chooses translocation rather than unroofing an intramural segment. The service is generally performed in a hospital operating room as part of cardiac surgery.

Select the code from the documented coronary origin and the operative technique; the report should identify the anomalous anatomy and describe the translocation or reimplantation. CMS assigns a 90-day global period, including 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 at 50%. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is 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.

How to choose

33504Coronary repair
Choose 33504 for translocation of a coronary artery arising from the pulmonary artery. Code 33506 describes translocation for a different anomalous coronary origin.
33505Coronary repair
33505 uses an intrapulmonary tunnel for an anomalous coronary artery arising from the pulmonary artery; 33506 uses origin translocation.
33507Coronary repair
33507 describes unroofing an intramural coronary segment. Use 33506 when the documented repair moves the anomalous origin instead.

33506 billing questions

How does 33506 differ from 33507?

33506 is for correcting the anomalous origin by translocation. 33507 describes repair by unroofing an intramural coronary segment; use the technique documented in the operative report.

How does 33506 differ from 33504?

33504 addresses an anomalous coronary artery arising from the pulmonary artery and translocates that origin. 33506 is for translocation of an anomalous coronary origin in a different anatomic setting.

What documentation supports reporting 33506?

The operative report should identify the coronary artery's anomalous origin and describe mobilization and translocation or reimplantation of its origin.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How are assistants and co-surgeons handled?

An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

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.
