Prone Transpsoas (PTP) Interbody Fusion
A patient presented for an L3-L4 anterior lumbar interbody fusion via lateral retroperitoneal transpsoas approach. The patient was placed in the prone position in anticipation of a single-position prone transpsoas (PTP) surgery. An incision was made over the left flank, a finger was used to dissect into the retroperitoneal space, and the psoas muscle was identified. The disk space at L3-L4 was mapped out, and the diskectomy proceeded in a piecemeal fashion. Progressive trials were placed in the disk space, and appropriately sized grafts were selected. The implant was loaded with cellular allograft and inserted into the disk space. What is the appropriate code to capture the L3-L4 anterior lumbar interbody fusion via a lateral retroperitoneal transpsoas approach? ...

Article Overview
This short coding article focuses on a lumbar interbody fusion performed through a prone transpsoas approach and explains the coding context for the procedure. It is relevant to inpatient procedural coders, CDI staff, and reimbursement professionals who work with spine surgery documentation and ICD-10-PCS assignment. The content centers on the operative approach, the anatomic level involved, and the procedure documentation needed to support code selection.
Why This Topic Matters
Approach-specific spine fusion cases can be difficult to classify correctly from the operative note alone, especially when multiple access routes or positioning details are mentioned. Understanding the procedure context helps coders map documentation to the appropriate ICD-10-PCS reporting structure.
