About 22858: Second-level cervical disc replacement
Reports artificial disc replacement at a second cervical interspace during the same operative service as the primary cervical disc arthroplasty.
A spine surgeon reports this add-on when replacing a damaged cervical disc with an artificial disc at a second interspace during the operative service. The procedure involves an anterior approach, removal of the treated disc, and preparation of the space for the implant. Typical cases involve cervical degenerative disc disease associated with nerve-root or spinal-cord symptoms. The code identifies the second treated interspace, not another service at the first level.
Report 22858 only with the primary cervical disc arthroplasty code, 22856. The operative report should identify both treated cervical interspaces and document the disc replacement performed at each. Routine removal of the disc and preparation of its space are part of the arthroplasty service, not separately counted as another level. Under the CMS rule for this add-on, it is paid within the primary procedure’s global period and cannot be billed by itself.

22858 billing questions
Can 22858 be billed by itself?
No. It is an add-on for a second cervical interspace and must be reported with the primary cervical arthroplasty code, 22856.
When should 22856 be reported instead?
Use 22856 for the primary cervical disc arthroplasty at one interspace. Report 22858 when a second cervical interspace is also treated with disc replacement during the operative service.
How many units of 22858 should be reported?
The code identifies the second cervical interspace. The operative report should support the additional treated level; do not use units to represent work at the primary interspace.
Is disc removal separately reported for the additional level?
Disc removal and preparation of the space for the artificial disc are part of the arthroplasty service. 22858 represents the additional replacement level, not a separate discectomy.
What documentation supports 22858?
Document the cervical interspaces treated and the artificial disc replacement at the second interspace. The record should also support the primary arthroplasty reported with 22856.
