Question: Then I did a lumbar decompression with posterior lumbar interbody fusion and posterior lateral transverse fusion with pedicular screws." How should I report this? Is the hemilaminectomy bundled with the fusion? Alabama Subscriber Answer: To report both, your physician must document he decompressed the spinal cord and/or nerve roots Report 63030 (Laminotomy [hemilaminectomy], with decompression of nerve root[s], including partial facetectomy, foraminotomy and/or excision of herniated intervertebral disc, including open and endoscopically-assisted approaches; 1 interspace, lumbar) for this part of the surgery. Be sure to append modifier 50 (Bilateral procedure) to indicate that the hemilaminectomy was bilateral. Next, report the posterior lumbar interbody fusion (PLIF), in which the vertebral endplates are separated and graft material inserted between them, using 22630 (Arthrodesis, posterior interbody technique, including laminectomy and/or discectomy to prepare interspace [other than for decompression], single interspace; lumbar). Report the posterior lateral transverse fusion using 22612 (Arthrodesis, posterior or posterolateral technique, single level; lumbar [with or without lateral transverse technique]). Attach modifier 51 (Multiple procedures) to 22612 since your physician performed both the PLIF and posterior lateral transverse fusion. Note: If he performed a two-level (i.e., three-segment) instrumentation attached at L4, L5, and S1, use +22842 (Posterior segmental instrumentation [e.g., pedicle fixation, dual rods with multiple hooks and subliminal wires]; 3 to 6 vertebral segments [List separately in addition to code for primary procedure]). If he placed the pedicle screws and attached the instrumentation at only two places, 22840 would be correct regardless of how many levels are between the endpoints. -- Reader Questions and You Be the Coder were reviewed by Heidi Stout, CPC, CCS-P, director of orthopedic coding services at The Coding Network LLC; and Bill Mallon, MD, orthopedic surgeon and medical director at Triangle Orthopaedic Associates in Durham, N.C.
