What 43337 covers
This code represents open repair of a diaphragmatic hernia using an approach that enters both the chest and abdomen, with mesh or another prosthetic material used to reinforce the defect. The surgeon reduces herniated abdominal contents and repairs the diaphragm; the combined access may be selected for a defect that requires exposure from both cavities. The service is performed in an operating room, typically by a surgeon treating a complex diaphragmatic defect in a hospital setting.
Select this code when the operative report supports the thoracoabdominal route and documents placement of mesh or another prosthesis; a thoracoabdominal repair without prosthetic reinforcement is represented by a related code. 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.

43337 billing questions
How is this code distinguished from 43336?
Both describe diaphragmatic hernia repair through thoracoabdominal access. Use 43337 when the repair includes mesh or another prosthetic material; 43336 represents the repair without that reinforcement.
When is a thoracoabdominal approach appropriate?
The operative report must support access through both the chest and abdomen for the diaphragmatic hernia repair. Do not select this code solely because the hernia is large or complex.
Can modifier 50 be reported?
No. The anatomy and service do not support a bilateral adjustment.
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.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does payment change 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.
