The anterior part of the spinal column refers to the spine that is at the front of the body. If the fusion that is being coded has documentation of an interbody fusion device/cages or described as interbody, that would mean that the anterior portion of the spine is where the fusion is taking place. This is not the same as the approach. We will discuss the different approaches in Tip 5.
The posterior part of the spinal column refers to the spine that is at the back of the body. If the operative note describes rods and screws with bone graft or decortication of the spinous processes this is in the posterior column. Other terms to help determine the posterior column are lamina, facet, articular process and transverse process.
Be sure and code both anterior and posterior fusion if both are documented. With all the advances in medical technology, both anterior and posterior fusions are being completed via one incision without having to turn the patient. We will learn more on the approaches in Tip 5.

Be on the lookout for Part 5, which will discuss how to identify the approach used for the spinal fusion.
