What 22870 covers

This add-on represents placement of an interspinous stabilization or distraction device at an additional lumbar segment. A spine surgeon, commonly an orthopedic spine surgeon or neurosurgeon, places the implant between adjacent spinous processes to provide stabilization or distraction. The procedure is performed without decompression at the treated level; the initial lumbar level is represented by the corresponding primary procedure. These implants are typically placed in an operating room for selected degenerative lumbar conditions.

Report one unit for each additional lumbar segment beyond the initial level, with the operative report identifying the treated levels and documenting device placement without decompression. Pair the code with the primary procedure for the initial level, typically 22869. CMS classifies 22870 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

22870 billing questions

When is 22870 reported instead of 22869?

22869 represents the initial lumbar segment treated without decompression. Use 22870 for each additional lumbar segment treated in the same manner.

Can 22870 be billed by itself?

No. It is an add-on code and must be reported with the primary procedure for the initial segment, typically 22869.

How many units should be reported?

Report one unit for each additional lumbar segment beyond the initial segment. The operative documentation should identify the levels treated.

How does 22870 differ from 22868?

22870 is for an additional segment treated without decompression. 22868 is the additional-segment code for the corresponding procedure performed with decompression.

What documentation supports 22870?

Document the additional lumbar level or levels, the placement of the interspinous stabilization device, and that decompression was not performed at those levels.
