What this is, in plain language
A procedure where a thin, flexible camera is passed through the mouth to examine the esophagus, stomach, and upper small intestine, with small tissue samples taken for testing.
Why a clinician orders it
Persistent heartburn, trouble swallowing, upper abdominal pain, bleeding, or abnormal imaging findings.
Medical necessity — what insurers usually look at
Covered when symptoms or findings justify it. Prior authorization is sometimes required for non-urgent endoscopy. Anesthesia and pathology are typically billed separately — ask about all three charges.
