There is no code for this procedure. This service is included in a laparoscopic Nissen procedure (43280, laparoscopy, surgical, esophagogastric fundoplasty [e.g., Nissen, Toupet procedures]).
In the rare event that a diaphragmatic hernia is repaired without a lap Nissen, an unlisted laparoscopy code such as 43289 (unlisted laparoscopy procedure, esophagus) or 49659 (unlisted laparoscopy procedure, hernioplasty, herniorrhaphy, herniotomy) should be used. Because unlisted codes spur automatic review, clear and accurate documentation of the procedure should accompany the claim.
