I need some advice regarding ultrasound billing in our office when our physician is on vacation. We have a certified ultrasound tech that is contracted to perform the scans. We also have 2 midlevel providers in the office at the time (just the MD is out). How do we/can we bill for this? We typically would bill a global code (ex 76830) under the physicians name. We found some information regarding the "physician supervision indicators", but are confused. Per CMS, 76830 has a physician indicator of 9 (concept does not apply) but we don't know how we should bill (76830 under physician, 76830 under midlevel, 76830.TC etc)??
