What 37788 covers
This operation surgically increases blood supply to the penis by reconstructing arterial inflow, generally through an arterial bypass or microsurgical connection. Urologists and surgeons experienced in penile microvascular surgery perform it in an operating room for selected patients with erectile dysfunction attributable to focal arterial injury or obstruction, such as after pelvic or perineal trauma, rather than diffuse vascular disease. The operative approach and vessels used depend on anatomy and findings.
Report this code for open arterial reconstruction, not penile venous occlusion or prosthesis insertion. The operative report should identify the indication, arterial problem, vessels reconstructed, technique, and work performed; erectile dysfunction alone does not establish that this operation was performed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

37788 billing questions
When should 37788 be chosen instead of 37790?
Use 37788 for open reconstruction of penile arterial inflow. Code 37790 describes penile venous occlusion, a different operation directed at venous outflow.
Is modifier 50 appropriate for bilateral reporting?
No. CMS identifies bilateral adjustment as inappropriate for this code, so do not append modifier 50 to indicate bilateral work.
What postoperative care is included in the global period?
The 90-day major-surgery global includes the day-before preoperative visit and 90 days of related postoperative care.
What documentation supports reporting 37788?
The operative report should show the focal arterial problem and describe the open reconstruction, including the vessels and technique. A diagnosis of erectile dysfunction by itself does not establish that revascularization was performed.
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.
