- Duplex scanning is covered to evaluate suspected chronic intestinal ischemia in patients with postprandial epigastric or periumbilical pain lasting 1–3 hours and associated weight loss from decreased oral intake.
- Duplex scanning is covered to evaluate suspected acute intestinal ischemia in patients with acute crampy or steady epigastric/periumbilical pain with minimal abdominal exam findings and leukocytosis.
- Duplex scanning is covered to evaluate possible injury to arterial inflow or venous outflow of abdominal, pelvic and/or retroperitoneal organs after trauma to those regions.
- Duplex scanning is covered to evaluate suspected aneurysm of the renal artery or another visceral artery based on signs/symptoms or incidental radiologic finding.
