Pt came in for a Nexplanon removal, but Dr. was not able to find it. Ultrasound was used on PT's arm in order to locate the device. I know a 11982 with a modifier should be used, but what about the ultrasound? Is it billable and if so, which CPT code should be used? I'm leaning towards CPT 76882. I have used a diagnosis of z97.8. Thank you!!
