Clinical Context
A typical patient is a 45–60-year-old adult with symptomatic single-level degenerative disc disease or symptomatic disc herniation at a lumbar interspace who previously underwent or is undergoing a primary lumbar total disc arthroplasty at an adjacent interspace during the same operative session. The patient presents with chronic low back pain, axial mechanical pain unresponsive to conservative care (physical therapy, pain injections, medications) and imaging (MRI/CT) demonstrating disc degeneration or focal disc pathology appropriate for total disc replacement.
Preoperative workflow includes outpatient evaluation by a spine surgeon (orthopedic spine or neurosurgery), imaging review, informed consent discussing risks/benefits/alternatives, and medical clearance. On the day of surgery the patient undergoes general endotracheal anesthesia and is positioned supine. The surgeon performs an anterior retroperitoneal or transperitoneal abdominal approach to the lumbar spine, exposes the target disc space, excises the native disc, prepares vertebral endplates, and implants an artificial disc device at the second interspace. Intraoperative steps often include fluoroscopic confirmation of level and implant position. Postoperative workflow includes PACU recovery, early mobilization per surgeon protocol, and discharge planning with activity restrictions and outpatient follow-up for wound check and imaging as indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|
62 | Two surgeons | When two surgeons of different specialties perform distinct, necessary parts of the procedure (e.g., vascular surgeon for anterior access plus spine surgeon for implant). |
| 63 | Procedure performed on infants younger than 4 years | Not typically used for adult lumbar disc arthroplasty; applicable only if patient meets age criterion.
| 66 | Surgical team (e.g., multiple specialists) | When a surgical team approach is documented for complex cases requiring coordinated roles.
| 78 | Unplanned return to the operating room for a related procedure during the global period | When an unplanned takeback for a complication related to the implant occurs during the global period.
| 79 | (Not in provided list) | Data not available in the input.
| 50 | Bilateral procedure | Not applicable for single-level lumbar disc arthroplasty; reserved for bilateral anatomic structures when both sides are operated on.
| 52 | Reduced services | When the procedure is started but substantially reduced or less of the service is performed than described.
| 53 | Discontinued procedure | When the procedure is started but terminated due to extenuating circumstances, prior to completion.
| 54 | Surgical care only | When billing only for the surgical component and another provider bills for postoperative management.
| 55 | Postoperative management only | When billing only for the postoperative care (another billed the surgical service).
| 56 | Preoperative management only | When only preoperative care is billed by the reporting provider.
| 23 | Unusual anesthesia | When general anesthesia cannot be used and documentation supports use of a significantly different anesthesia technique considered unusual.
| 22 | Increased procedural services | When intraoperative work is substantially greater than usual and properly documented to support unusual effort.
| 73 | Discontinued outpatient hospital/ambulatory surgery center (ASC) procedure prior to anesthesia | When the planned outpatient procedure is cancelled before anesthesia administration.
| 80 | Assistant surgeon | When an assistant surgeon actively assists and documentation supports the assistant role.

Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|
M51.36 | Other intervertebral disc degeneration, lumbar region | Degenerative disc disease at the lumbar level is a primary indication for lumbar total disc arthroplasty. |
| M51.37 | Other intervertebral disc degeneration, lumbosacral region | Degeneration at the lumbosacral junction may be treated with disc arthroplasty when anatomy and indications permit.
| M51.26 | Intervertebral disc displacement, lumbar region | Symptomatic disc displacement (herniation) causing persistent pain or neurogenic symptoms may be an indication for disc replacement when conservative care fails.
| M51.27 | Intervertebral disc displacement, lumbosacral region | Displacement at lumbosacral level potentially treated with arthroplasty depending on pathology and patient selection.
| M54.5 | Low back pain | Common symptom prompting evaluation and possible surgical intervention including disc arthroplasty.
| M48.06 | Spinal stenosis, lumbar region | In selected patients with predominant disc disease and limited stenosis, disc arthroplasty may be considered as part of surgical strategy.
| M53.2X6 | Spinal instabilities, lumbar region | Segmental instability related to disc degeneration may be addressed by arthroplasty in appropriately selected cases.
| G89.29 | Other chronic pain | Chronic axial low back pain refractory to conservative measures is often present in candidates for disc arthroplasty.
