ICD-10-PCS Code for Thoracolumbar Vertebral Joint: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group XRGA includes procedures performed to join together portions of an articular body part rendering the articular body part immobile in the thoracolumbar vertebral joint. These ICD-10-PCS codes are used for inpatient documentation when fusion of thoracolumbar vertebral joints is performed to stabilize the spine or treat degenerative, traumatic, or deformity conditions. Accurate coding within the ICD-10-PCS XRGA group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Thoracolumbar Vertebral Joint Fusion Procedure Overview

This procedure group includes fusion operations that join together portions of thoracolumbar vertebral joints to render the articular body part immobile. The procedures target the joints of the thoracolumbar spine within the joints body system and typically use biological or mechanical means to achieve immobility. Accurate ICD-10-PCS coding of these fusion procedures is important for inpatient reimbursement because it documents the specific operation and anatomical site treated.

When to Use

Use a code from this group when a thoracolumbar vertebral joint fusion is performed during an inpatient encounter to stabilize the spine or relieve pain from joint pathology. These codes apply when the operation intentionally renders the articular body part immobile as the primary procedure.

Typical Clinical Scenarios

An elderly patient presents after a fall with progressive neurogenic claudication and imaging shows multilevel thoracolumbar instability with facet joint degeneration and spondylolisthesis causing foraminal stenosis. During an urgent inpatient fusion to stabilize the motion segment and relieve nerve compression, paired titanium cages are placed across the facet joints via an open approach to achieve arthrodesis and immediate mechanical stabilization. The primary intent is to render the involved thoracolumbar articular joints immobile to prevent further neurologic deterioration. Typical codes: XRGA0EA
A middle-aged patient with chronic mechanical back pain and radiographic evidence of degenerative disc disease and collapsed intervertebral height at a thoracolumbar level elects for definitive surgical stabilization after failing conservative therapy. In a planned inpatient procedure, a custom-made anatomically designed interbody fusion device is implanted using a percutaneous approach to achieve fusion of the thoracolumbar articular joint and restore segmental stability. The operation is intended to produce long-term immobilization of the affected joint to alleviate pain and correct segmental instability. Typical codes: XRGA3R7
A patient with prior open posterior thoracolumbar instrumentation develops persistent pain and evidence of pseudoarthrosis on imaging with continued motion at the fused level. In a revision inpatient operation, a custom-made anatomically designed interbody fusion device is placed via an open approach to re-establish solid fusion of the thoracolumbar articular joints and eliminate abnormal motion. The revision targets the same articular body part to render it immobile and promote durable arthrodesis. Typical codes: XRGA0R7
