Clinical Context
A patient with chronic dysphagia and inadequate oral intake presents for placement of a low-profile gastrostomy/jejunostomy tube for long-term enteral nutrition. Typical candidates include adults with neurologic disorders (for example, stroke with persistent swallowing dysfunction), head and neck cancer patients after resection/repair, or patients with severe esophageal motility disorders. The procedure may be performed percutaneously under endoscopic or fluoroscopic guidance in an interventional radiology suite or endoscopy/operating room. Pre-procedure workflow includes informed consent, review of anticoagulation and infection risk, fasting, and appropriate imaging or endoscopic evaluation. The low-profile enteral tube (billing code B4088) is placed either at the time of primary access creation (gastrostomy or gastrojejunostomy) or as a replacement of a mature tract. Post-procedure workflow includes confirmation of tube position, initiation of appropriate feeding protocol, documentation of tube size and type, discharge instructions for stoma care, and scheduling of follow-up for tube maintenance or exchange. Typical site of service is an outpatient ambulatory surgery center, hospital outpatient department, interventional radiology suite, or inpatient ward when medically necessary.
