Single Unit of 77301 Is Best Choice for IMRT
Published on Thu Jun 26, 2008
Question: Our oncologist is treating multiple targets in a single anatomic site using IMRT. How many units of 77301 should I be reporting -- one unit total or one per target? Oklahoma Subscriber Answer: Your correct coding option for IMRT is to report one unit of 77301 (Intensity modulated radiotherapy plan, including dose-volume histograms for target and critical structure partial tolerance specifications) per treatment course, even when your oncologist is treating multiple targets in the same anatomic site. What it is: IMRT allows physicians to deliver high-dose radiation to some parts of a tumor while delivering lower-dose radiation to areas near sensitive tissues. How to play it safe: Just like any other emerging technology, you-ll want to check your payer policies for any relevant updates.
