A. Patient Betsy Froman, who is enrolled in TRICARE standard, has been referred to you, the health insurance professional at Broamoor Clinic, with this question: “” I am scheduled for an outpatient echocardiogram at Broadmoor Meidcal Center next week. What, if anything, need to be done before I have this procedure?”” What should you tell Ms. Froman? Will she need an NAS?
