Compliance with the provisions in this policy may be monitored and addressed
through post payment data analysis and subsequent medical review audits.  
  
 **History/Background and/or General Information  
  
** These endoscopic examinations may be used to evaluate symptoms, identify
anatomic abnormalities, to obtain biopsies, or are employed for therapeutic
reasons. Most often the procedure is performed by a fiber-optic endoscope
(including video endoscopy), a flexible tube containing light transmitting
glass fibers that return a magnified image directly or by video. **  
  
 **Covered Indications**  
  
** Endoscopy procedures can only be allowed if abnormal signs or symptoms or
known disease are present.

  1. Indications which support esophagogastroduodenoscopies (EGD[s]) for diagnostic purpose(s) are as follows:   
  

    * Upper abdominal distress which persists despite an appropriate trial of therapy;
    * Upper abdominal distress associated with symptoms and/or signs suggesting serious organic disease (e.g., prolonged anorexia and weight loss);
    * Dysphagia or odynophagia;
    * Esophageal reflux symptoms which are persistent or recurrent despite appropriate therapy;
    * Persistent vomiting of unknown cause;
    * Other systemic diseases in which the presence of upper GI pathology might modify other planned management. Examples include patients with a history of GI bleeding who are scheduled for organ transplantation; long term anticoagulation; and chronic non-steroidal therapy for arthritis;
    * X-ray findings of:  

      * A suspected neoplastic lesion, for confirmation and specific histologic diagnosis;
      * Gastric or esophageal ulcer; or
      * Evidence of upper gastrointestinal tract stricture or obstruction.
    * The presence of gastrointestinal bleeding:  

      * In most actively bleeding patients or those recently stopped;
      * When surgical therapy is contemplated;
      * When re-bleeding occurs after acute self-limited blood loss or after endoscopic therapy;
      * When portal hypertension or aortoenteric fistula is suspected; or
      * For presumed chronic blood loss and for iron deficiency anemia when colonoscopy is negative.
    * When sampling of duodenal or jejunal tissue or fluid is indicated;
    * To assess acute injury after caustic agent ingestion; or
    * Intraoperative EGD when necessary to clarify location or pathology of a lesion.
  2. Indications which support EGD(s) for therapeutic purpose(s) are as follows:  
  

    * Treatment of bleeding from lesions such as ulcers, tumors, vascular malformations (e.g., electrocoagulation, heater probe, laser photocoagulation or injection therapy);
    * Sclerotherapy for bleeding from esophageal or proximal gastric varices or banding of varices;
    * Foreign body removal;
    * Removal of selected polypoid lesions;
    * Placement of feeding tubes (oral, percutaneous endoscopic gastrostomy, percutaneous endoscopic jejunostomy);
    * Dilation of stenotic lesions (e.g., with transendoscopic balloon dilators or dilating systems employing guidewires); or
    * Palliative therapy of stenosing neoplasms (e.g., laser, bipolar electrocoagulation, stent placement).
  3. Sequential or periodic diagnostic upper GI endoscopy may be indicated for an appropriate number of procedures for active or symptomatic conditions.  
  

    * For follow-up of selected esophageal, gastric or stomal ulcers to demonstrate healing (frequency of follow-up EGDs is variable, but every two to four months until healing is demonstrated is reasonable);
    * For follow-up in patients with prior adenomatous gastric polyps (approximate frequency of follow-up EGDs would be every one to four years depending on the clinical circumstances, with occasional patients with sessile polyps requiring every six-month surveillance initially);
    * For follow-up for adequacy of prior sclerotherapy or banding of esophageal varices (approximate frequency of follow-up EGDs is very variable depending on the state of the patient but every six to twenty-four months is reasonable after the initial sclerotherapy/banding sessions are completed);
    * For follow-up of Barrett's esophagus (approximate frequency of follow-up EGDs is one to two years with biopsies, unless dysplasia or atypia is demonstrated, in which case a repeat biopsy in two to three months might be indicated); or
    * For follow-up in patients with familial adenomatous polyposis (approximate frequency of follow-up EGDs would be every two to four years, but might be more frequent, such as every six to twelve months if gastric adenomas or adenomas of the duodenum were demonstrated).
  4. The endoscopic retrograde cholangiopancreatography (ERCP) procedure is generally indicated for certain biliary and pancreatic conditions.  
  

    * ERCP is generally not indicated for the diagnosis of pancreatitis except for gallstone pancreatitis;
    * ERCP is not usually indicated in early stages or in acute pancreatitis and could possibly exacerbate it;
    * ERCP may be useful in traumatic pancreatitis to accurately localize the injury and provide endoscopic drainage;
    * ERCP may be useful in pancreatic duct stricture evaluation;
    * ERCP may be useful for the extraction of bile duct stones in severe gallstone induced pancreatitis;
    * ERCP may be useful in detecting pancreatic ductal changes in chronic pancreatitis and also the presence of calcified stones in the ductal system. A pancreatogram may be performed and is likely to be abnormal in chronic alcoholic pancreatitis but less so in non-alcoholic induced types;
    * ERCP may be useful in detecting gallstones in symptomatic patients whose oral cholecystogram and gallbladder ultrasonograms are normal; and
    * ERCP may be indicated in patients with radiologic imaging suggestive of common bile duct stones or other potential pathology.

  
**Limitations**  
  

  1. Indications for which EGD(s) are generally not covered by Medicare are as follows:   
  

    * Distress which is chronic, non-progressive, atypical for known organic disease, and is considered functional in origin (there are occasional exceptions in which an endoscopic examination may be done once to rule out organic disease, especially if symptoms are unresponsive to therapy);
    * Uncomplicated heartburn responding to medical therapy;
    * Metastatic adenocarcinoma of unknown primary site when the results will not alter management;
    * X-ray findings of:  

      * asymptomatic or uncomplicated sliding hiatal hernia;
      * uncomplicated duodenal bulb ulcer which has responded to therapy; or
      * Deformed duodenal bulb when symptoms are absent or respond adequately to ulcer therapy;
    * Routine screening of the upper gastrointestinal tract;
    * Patients without current gastrointestinal symptoms about to undergo elective surgery for non-upper gastrointestinal disease; or
    * When lower G.I. endoscopy reveals the cause of symptoms, abnormal signs or laboratory tests (e.g., colonic neoplasm with iron deficiency anemia). Exceptions can be considered if medical necessity for this procedure can be demonstrated.
  2. Sequential or periodic diagnostic EGD is not indicated for:   
  

    * Surveillance for malignancy in patients with gastric atrophy, pernicious anemia, treated achalasia, or prior gastric operation;
    * Surveillance of healed benign disease such as esophagitis, gastric or duodenal ulcer; or
    * Surveillance during chronic repeated dilations of benign strictures unless there is a change in status.

**Place of Services (POS)**

These services may be performed in a physician's office, or in a hospital
inpatient or outpatient, or an ASC.  
  

**Notice:** Services performed for any given diagnosis must meet all of the
indications and limitations stated in this policy, the general requirements
for medical necessity as stated in CMS payment policy manuals, any and all
existing CMS national coverage determinations, and all Medicare payment rules.

The redetermination process may be utilized for consideration of services
performed outside of the reasonable and necessary requirements in this LCD.
