Recent opinion lines up anatomical regions with US codes. Being that current payer policy on imaging guidance is especially strict, you don't want to miscode any ultrasound (US) services your ED physician provides. CPT Assistant has recently published a Q&A set that will help you get all the reimbursement you deserve for US service, without getting payback requests on improperly coded US. Mediastinum Is Not Necessary for Chest US CPT Assistant No; however, if an examination of the mediastinum is indicated, it is included in chest US (76604, Ultrasound, chest [includes mediastinum], real time with image documentation), confirms Elijah Berg, MD, FACEP, CEO of MRSI, an ED coding and billing company in Woburn, Mass. Impact: Where is it? Use These CPT Designations on Soft-Tissue US CPT Assistant • neck: 76536 (Ultrasound, soft tissues of head and neck [e.g., thyroid, parathyroid, parotid], real time with image documentation) • chest wall, upper back: 76604 • lower back, abdominal wall: 76705 (Ultrasound, abdominal, real time with image documentation; limited [e.g., single organ, quadrant, follow-up]) • pelvic wall, buttock, perineum: 76857 (Ultrasound, pelvic [nonobstetric], real time with image documentation; limited or follow-up [e.g., for follicles]) • upper extremity, axilla, groin, lower extremity: 76880 (Ultrasound, extremity, nonvascular, real time with image documentation) • other soft tissue: 76999 (Unlisted ultrasound procedure [e.g. diagnostic, interventional]). Previously, there was no uniform guidance on how to code soft-tissue US of the above areas other than the head and neck. Coders were forced to pick the code that most closely described the area the physician was examining, which led to confusion. Now, CPT has made those anatomical US assignments for you, which should make getting paid for these services easier. Remember Modifier 26 Any time you use one of the above US codes for your ED physician's services, be sure to append modifier 26 (Professional component) to show that you are only coding for your physician's work, not the US equipment.
