About 43236: Upper GI endoscopy with submucosal injection
Reports upper GI endoscopy with directed injection into the submucosa, such as tattooing a lesion or lifting it for endoscopic treatment.
During an upper GI endoscopy, the physician directs a substance into the submucosal layer of the esophagus, stomach, or duodenum. Common purposes include placing tattoo ink to help locate a lesion later or injecting a lifting solution beneath a lesion before endoscopic treatment. Gastroenterologists and other physicians who perform upper endoscopy may provide the service in an office endoscopy suite or a hospital outpatient endoscopy unit.
Select this code when the procedure documentation supports directed submucosal injection, not merely diagnostic inspection or tissue sampling. Record the injection site, substance, purpose, endoscopic findings, and any other intervention performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy-family pricing applies. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

43236 billing questions
When should this code be chosen instead of 43243?
Use 43236 for directed submucosal injection such as lesion marking or lifting. Code 43243 describes injection treatment of esophageal varices.
Is the code reported once for each injection site?
The code describes the endoscopic injection service, including one or more injections. Documentation should identify the treated site or sites and the purpose.
Can biopsy or lesion removal also be reported?
The injection service is distinct from tissue sampling or lesion removal, but same-session reporting depends on applicable coding edits. CMS endoscopy-family pricing applies when related endoscopies are performed together.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant, co-surgeon, or surgical team be paid?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
