There seems to be some confusion regarding the use of 22845, Anterior instrumentation; 2 to 3 vertebral segments. However, CPT code descriptor, coding instructions and examples, appear to indicate that this code should be reported in addition to other primary procedure(s) which do not involve scoliosis correction or lumbar spine only. I understand if the instrumentation is part of a device (i.e. synthetic cage), the screws and plates are included and not reported separately.
Can CPT code 22845 be reported for other conditions besides scoliosis or the lumbar spine?
Yes, it would be appropriate to report CPT code 22845, Anterior instrumentation; 2 to 3 vertebral segments, for anterior instrumentation in different spinal procedures other than scoliosis and in other vertebrae other than the lumbar spine when performed. This CPT code is not exclusive to the lumbar spine. CPT coding description of a vertebral segment states “a vertebral segment describes the basic constituent part into which the spine may be divided. It represents a single complete vertebral bone with its associated articular processes and laminae”.
