About 22857: Single-level lumbar artificial disc replacement
Reports anterior placement of an artificial disc at one lumbar interspace after discectomy and endplate preparation, preserving motion rather than fusing the segment.
A spine surgeon, commonly an orthopedic spine surgeon or neurosurgeon, removes the lumbar disc through an anterior approach, prepares the vertebral endplates, and places an artificial disc prosthesis at one interspace. The operation is generally performed in a hospital or ambulatory surgery setting for selected patients with symptomatic lumbar degenerative disc disease. The work includes the discectomy, endplate preparation, and associated osteophyte removal described for the procedure.
Report 22857 for the primary lumbar interspace; use 22860 for each additional lumbar interspace when applicable. The operative report should identify the lumbar level, anterior approach, disc removal and endplate preparation, and prosthesis placement. CMS includes the day-before preoperative visit and 90 days of related postoperative care in the 90-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this single spinal interspace. Assistant-at-surgery payment may be made, co-surgeons are permitted, and team-surgery payment is not permitted.

22857 billing questions
When is 22860 reported with 22857?
Report 22857 for the primary lumbar interspace and 22860 for each additional lumbar interspace treated during the same operation. The documentation should identify the treated levels.
How is 22857 different from lumbar fusion?
22857 describes placement of an artificial disc after discectomy and endplate preparation. A lumbar fusion code such as 22558 describes arthrodesis rather than motion-preserving disc replacement.
Can modifier 50 be used for 22857?
No. The code represents treatment of one spinal interspace, not a paired body structure, and the CMS bilateral adjustment is unavailable.
What work is included in 22857?
The service includes disc removal, endplate preparation, and the associated osteophyte removal described for the procedure, along with placement of the artificial disc. Document these operative steps and the lumbar level.
What are the assistant and co-surgeon rules?
CMS allows assistant-at-surgery payment and permits co-surgeons for 22857. Team-surgery payment is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
