63047 with 22633 for Interbody Fusion?
Question:
We would like some coding insight from KZA. Can you report CPT code 63047 with 22633 if you append modifier 51 to CPT code 63047 if the documentation supports the work done beyond that required for interbody fusion?
Answer:
Thank you for asking KZA!
CPT 63047 should not be reported with CPT 22633 at the same level/interspace.
Add-on codes (63052 & 63053) exist for decompression at the same level or interspace with a posterior lumbar interbody fusion (22630-22634). Remember, this is for decompression beyond preparation of the interspaces for fusion.
63052 – Laminectomy, facetectomy, or foraminotomy (unilateral or bilateral with decompression of spinal cord, cauda equina and/or nerve root[s] [eg, spinal or lateral recess stenosis]), during posterior interbody arthrodesis, lumbar; single vertebral segment
63053 – Laminectomy, facetectomy, or foraminotomy (unilateral or bilateral with decompression of spinal cord, cauda equina and/or nerve root[s] [eg, spinal or lateral recess stenosis]), during posterior interbody arthrodesis, lumbar; each additional vertebral segment
In the submitted scenario, the appropriate code to report is CPT 63052 if your documentation supports additional decompression.
