Wireless Capsule Endoscopy of Small Intestine
Wireless capsule endoscopy of the small bowel (91110) is considered medically necessary for obscure digestive tract bleeding, the site of which has not previously been identified by upper gastrointestinal endoscopy, colonoscopy, push enteroscopy, nuclear imaging, or radiological procedures.
This test is indicated for the following diagnosis for those patients who have undergone complete gastrointestinal studies:
-
Angiodysplasias of the gastrointestinal tract (569.85)
-
Hereditary gastrointestinal polyposis syndromes including familial polyposis (211.2, 211.3)
-
Initial diagnosis of suspected Crohn’s disease (555.0)
-
Occult gastrointestinal bleeding (562.02, 562.03, 569.86, 578.1, 578.9, 792.1)
-
Peutz-Jeghers syndrome (759.6)
Claims reporting conditions other than those referenced above should be denied as not medically necessary and, therefore, not covered. A participating, preferred, or network provider cannot bill the member for the denied service.
Wireless capsule endoscopy is limited to those patients who have undergone complete gastrointestinal studies (i.e., barium enema, stool specimen, upper gastrointestinal endoscopy, and colonoscopy), and such studies fail to reveal a source of bleeding. Medical record documentation must indicate that the member has continuing GI blood loss and anemia secondary to the bleeding.
Wireless Capsule Endoscopy of the Esophagus
Wireless capsule endoscopy of the esophagus (91111) is considered experimental/investigational. Clinical data are inadequate to permit scientific conclusions regarding the clinical role of esophageal capsule endoscopy. A participating, preferred, or network provider can bill the member for the denied service.

Description
Wireless capsule endoscopy is an ingestible telemetric gastrointestinal capsule imaging system that is used for visualization of the small bowel mucosa. It is used in the detection of abnormalities of the small bowel, which are not accessible via standard upper gastrointestinal endoscopy and colonoscopy. A small capsule (approximately 11x30mm) is swallowed and moves through the GI tract propelled by peristalsis, transmitting video pictures. The video images are transmitted to sensors taped to the body and stored on a portable recorder. The strength of the signal is used to calculate the position of the capsule as it passes through the GI tract. Video images are stored on a portable recorder and later downloaded to a computer, from which they may be viewed in real time. The capsule passes naturally from the body with the stool. Since it is disposable, it is not recovered.
In November 2004, the Given® Diagnostic System with the PillCamTM ESO Capsule received FDA clearance for the visualization of esophageal mucosa.
In the esophagus, the capsule camera has been proposed as a screening technique for Barrett's esophagus associated with gastroesophageal reflux disease (GERD). Evaluation of the esophagus requires limited transit time, and it is estimated that the test takes 20 minutes to perform. Alternative techniques include upper endoscopy. |
