Congenital heart surgery

About 33770: TGA repair without VSD enlargement

Open congenital heart repair for transposition of the great arteries with a ventricular septal defect when the defect is not surgically enlarged.

This major open operation repairs transposition of the great arteries in a patient who also has a ventricular septal defect. The congenital cardiac surgeon uses the existing defect to create an effective route for blood flow without surgically enlarging it. The operative report should establish the anatomy and describe the repair, including whether the VSD was enlarged. This is a hospital operating-room service, not an office procedure.

Report this code when the documented repair matches the no-enlargement approach; use the sibling code when the surgeon enlarges the VSD. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33770 billing questions

How do I distinguish this code from 33771?

The operative report must show whether the surgeon enlarged the VSD. This code is for the repair without enlargement; 33771 is the sibling code for a repair that includes enlargement.

What documentation supports reporting this code?

Document the transposition anatomy, the VSD, the repair performed, and whether the surgeon enlarged the defect. The operative note should support the selected repair approach.

Does the 90-day global include related postoperative care?

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

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Should modifier 50 be used?

No. Bilateral adjustment does not apply, and modifier 50 is inappropriate for this repair.

How is this code affected by other procedures performed in the same session?

The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction.
