Thoracic surgery
About 32665: Thoracoscopic esophageal myotomy
Reports thoracoscopic division or removal of esophageal muscle, typically for achalasia, with fundoplasty included when performed.
This code describes a thoracoscopic Heller-type myotomy: the surgeon reaches the esophagus through the chest and divides or excises muscle to relieve an obstructive esophageal motility disorder, most commonly achalasia. The operation is performed by a thoracic or other appropriately trained surgeon in an operating room. Fundoplasty performed as part of the operation is included in this service rather than separately reported as a separate procedure.
Report the code when the operative record supports a thoracoscopic esophageal muscle procedure, not merely inspection, biopsy, or resection of another thoracic structure. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

32665 billing questions
How does this differ from laparoscopic Heller myotomy?
This code is for the thoracoscopic route through the chest. CPT 43279 describes the laparoscopic route through the abdomen.
Can fundoplasty be reported separately?
Fundoplasty performed as part of the thoracoscopic Heller procedure is included in this code and is not separately reported as that component.
What documentation supports reporting this code?
The operative report should identify the thoracoscopic approach and describe the esophageal muscle myotomy or excision, along with any fundoplasty performed.
Does modifier 50 apply when both sides are treated?
No. Modifier 50 is inappropriate for this code because the descriptor and anatomy do not support bilateral adjustment.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
