Plus: CMS gives hospices extra time to comply with new requirements. You're probably just getting comfortable with your new edition of HCPCS 2010, but you'll have to make a few changes to ensure that your manual is completely accurate. CMS recently issued the list of corrections that you should make to your HCPCS 2010 book, including the following changes: • Change the descriptor for C8923 to "Transthoracic echocardiography with contrast, or without contrast followed by with contrast, real-time with image documentation (2D), includes M-mode recording, when performed, complete, without spectral or color doppler echocardiography." • Change the description of C8928 to "Implantable neurostimulator electrode, each."
