Esophageal surgery
About 43330: Abdominal esophageal myotomy
An abdominal Heller-type myotomy divides the esophageal muscle to relieve achalasia-related obstruction and is reported for the abdominal operative approach.
This operation divides the muscle layer of the lower esophagus through an abdominal approach to ease passage of food into the stomach. It is most commonly performed by a general or thoracic surgeon for achalasia when the lower esophageal sphincter fails to relax. The service is generally performed in a hospital operating room. A fundoplication may also be performed to reduce reflux after the muscle is divided; the operative report should identify each procedure actually completed.
Select this code for the abdominal approach, not a thoracic or laparoscopic myotomy. Documentation should establish the indication, approach, extent of the myotomy, and any additional procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this single midline operation. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

43330 billing questions
How does 43330 differ from 43331?
43330 is for the abdominal approach; 43331 is for a thoracic approach. The operative report should support the route used.
When would 43279 be more appropriate?
Use 43279 for laparoscopic Heller-type esophagomyotomy. Its descriptor includes fundoplasty when performed, unlike this abdominal-approach code.
Is a fundoplication included in 43330?
Document whether a fundoplication was performed as a separate operative step. Do not infer a separately reportable service merely because a wrap commonly accompanies a Heller myotomy.
Can modifier 50 be used?
No. This is a single abdominal myotomy, not a procedure performed on paired sides.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care through the 90-day period.
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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
