# CPT 64494

> Medicare paid $91.50 for CPT 64494 in the office (non-facility) setting and $51.17 in a facility under the Q4 2023 Physician Fee Schedule, effective October 2023. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2023, when it decreased 2.1%.

## What it is

The second facet joint level injected in the lumbar or sacral spine during the same session, again with imaging guidance. Facet pain rarely sits at a single segment, so physicians commonly treat two or three neighbouring levels in one visit; this entry covers the second of them. The technique is identical to the first-level injection - only the spinal segment differs.
