Congenital cardiac surgery
About 33775: Transposition repair with atrial baffle and band removal
Reports surgical repair of transposition of the great arteries using an atrial baffle, when a previously placed pulmonary artery band is also removed.
A congenital heart surgeon reports this code for an atrial-switch repair of transposition of the great arteries that includes taking off a pulmonary artery band placed during earlier treatment. The operation redirects blood flow at the atrial level and removes the band during the same surgical session. It is performed in an operating room, generally as major open-heart surgery for congenital heart disease.
Choose this code when the operative report supports both the atrial baffle repair and pulmonary artery band removal; the band removal is part of this service, not a separate reason to select the code. Document the underlying anatomy, the baffle work, and removal of the prior band. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this code.

33775 billing questions
How does this differ from 33774?
Use 33775 when the atrial-baffle repair also includes removal of a pulmonary artery band. Code 33774 describes the atrial-baffle repair without that band-removal distinction.
Is pulmonary artery band removal separately reported?
The band removal is included in this repair when performed as part of the same operation. Document it in the operative report as part of the service.
What documentation supports choosing this code?
The operative report should identify the transposition repair, atrial baffle work, and removal of a previously placed pulmonary artery band.
Can modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor and anatomy.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction. The code has a 90-day global period.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted for this code.
