What 43753 covers
A clinician passes a tube into the stomach and aspirates gastric contents to relieve distention or decompress the stomach. Lavage may be part of the service when performed. A typical situation is therapeutic decompression in a hospital or emergency setting. The service is distinct from placing a tube for feeding and from collecting gastric contents for diagnostic testing.
Report 43753 when the documented purpose is treatment, such as decompression, and the procedure includes gastric aspiration. The record should support the therapeutic indication and describe the intubation and aspiration performed; document lavage if performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted, and modifier 50 is inappropriate for this service.
