OTHER TERMS AND DEFINITIONS
                  1. The preamble to the Musculoskeletal System Surgical Procedures section also applies to this
                     section as applicable (e.g. fractures).
                  2. Fusion of one disc level (one motion segment) includes two levels of instrumentation.
                  3. Obtaining bone for grafting is included as a component of all fusion procedures and is not
                     eligible for payment when performed with any fusion procedure.
                  4. Thoracotomy performed in conjunction with spinal procedures by a surgeon not performing the
                     spinal surgery constitutes M137 (P14).
                  5. Laparotomy performed in conjunction with spinal procedures by a surgeon not performing the
                     spinal surgery constitutes S312 (S34).
                  6. Three-dimensional (3D) computer-assisted stereotactic navigation (E378) must include the pre-
                     operative or intra-operative generation of axial, sagittal and coronal reformatted images that are
                     processed and virtually represented in 3D by a surgical navigational system. In addition, the
                     surgical navigational system must be used to reflect the position of an image-guided (tracked)
                     surgical tool(s) relative to the patient's anatomy. This may be performed by either frame or
                     frameless technique and applies to any spinal level.
                  7. Two-dimensional (2D) computer-assisted stereotactic navigation (E379) must include the intra-
                     operative generation of antero-posterior, lateral or multiple oblique 2D views that are processed
                     and virtually represented in 2D by a surgical navigational system. In addition, the surgical
                     navigational system must be used to reflect the position of an image-guided (tracked) surgical
                     tool(s) relative to the patient's anatomy. This may be performed by either frame or frameless
                     technique and applies to any spinal level.
                     Note:
                     The use of an intra-operative imaging tool such as a portable x-ray, fluoroscope (2D or 3D), CT,
                     MRI or ultrasound for "live" localization without a surgical navigational system as defined
                     above does not constitute E378 or E379 and is not eligible for payment.
                  8. Acute spinal cord injury premium (E383) is only eligible for payment when rendered to patients
                     who are described under ASIA impairment scale ratings A to C and have acute conditions
                     which have been present for 6 weeks or less.
