I have a program on my computer called Code Manager published by the AMA. It is indispensable, I use it almost daily. It has CPT, ICD-9, CCI edits, and clinical vignettes that I use for appeals. Below is an example of a vignette regarding your question about 63047 reported with 22630:
January 2001 page 12
Question
The descriptors of codes 22554 and 22630 describe anterior (22554) or posterior (22630) interbody technique arthrodeses to include laminectomy, and/or diskectomy to prepare the interspace (other than for decompression). In what procedural circumstance would the 63001-63048 code(s) be reported in addition to code 22630? Similarly, in what procedural circumstance would code(s) 63075-63078 be reported in addition to code 22554?
AMA Comment
To report code 22630, Arthrodesis, posterior interbody technique, including laminectomy and/or diskectomy to prepare interspace (other than for decompression), single interspace; lumbar, in addition to code 63047-51, Laminectomy, facetectomy and foraminotomy (unilateral or bilateral with decompression of spinal cord, cauda equina and/or nerve root, [eg, spinal or lateral recess stenosis]), single vertebral segment; lumbar, again additional procedure(s) must have been performed. For example, in spinal procedures performed on patients having lateral lumbar stenosis, the surgeon may need to perform additional work above and beyond that described by the PLIF, including facetectomy(ies) and/or foraminotomy(ies), to adequately decompress the nerve roots. For the purpose of this example, code 63047-51 should be reported in addition to code 22630.
Hope this helps!
