Cervical stenosis with myelopathy / cervical radiculopathy

Posterior cervical laminectomy [C3-C6 / specify levels] [with / without] instrumented fusion
[***, MD/DO]
[Resident/Fellow/PA name]
General endotracheal
Patient presents with [cervical myelopathy / multilevel radiculopathy] refractory to conservative management. MRI demonstrates [multilevel stenosis / OPLL / hypertrophied ligamentum flavum] at [C3-C6 / specify]. T2 signal change in cord at [level]. Cervical alignment [lordotic / neutral / kyphotic — fusion required if kyphotic]. [SSEP/MEP] baselines established. Risks including infection, CSF leak, neurological deterioration, C5 nerve root palsy (5-11% incidence with laminectomy+fusion), hardware failure, adjacent segment disease, and post-laminectomy kyphosis (if fusion not performed) discussed. Consent obtained.
Midline posterior approach to the cervical spine. Laminae identified from [C3-C6]. Ligamentum flavum hypertrophied at [levels]. Dura decompressed after laminectomy. Pulsatile dural movement confirmed at completion.
The patient was positioned prone in Mayfield 3-pin fixation after induction. Neuromonitoring baselines recorded. Lateral fluoroscopy confirmed appropriate cervical alignment. The posterior neck was prepped and draped in sterile fashion.
A midline longitudinal incision was made from [C2 to C7]. Subperiosteal dissection of the paraspinal muscles was carried bilaterally to the lateral masses. Self-retaining retractors placed. Fluoroscopy confirmed levels. The spinous processes were removed with Leksell rongeur. The laminae were thinned with a high-speed drill and removed using Kerrison rongeurs bilaterally from [C3-C6]. Ligamentum flavum was sharply removed. The dura was decompressed and pulsatile motion confirmed.
[Bilateral foraminotomies were performed at [C5-6 / levels] using 2-mm Kerrison rongeur to address foraminal stenosis.]
[For instrumented fusion:] Lateral mass screws were placed bilaterally at [C3-C6] using the An technique. Rod cut to length and secured. Bone graft applied to decorticated lateral masses. Fluoroscopic confirmation of hardware position.
The wound was irrigated copiously. Muscle and fascia closed in layers. Skin closed with staples. Cervical collar applied. Patient tolerated the procedure well.

Laminoplasty (open-door or French-door)
Motion-preserving alternative. Requires lordotic or neutral alignment — contraindicated with >13 degrees of kyphosis or significant preoperative axial neck pain. Open-door (Hirabayashi) technique: lamina completely cut on open side, greenstick fracture hinge on contralateral side (one hinge). French-door (Kurokawa) technique: midline spinous process split with bilateral hinges at the lamina-facet junction (two hinges). Document which technique, hinge side for open-door, opening size, mini-plate fixation, and whether graft placed in the gutter.
Laminotomy/foraminotomy only
For single-level foraminal stenosis causing radiculopathy, without global central stenosis. Document hemilaminotomy, medial facetectomy extent, and nerve root decompression confirmed.
Charting Tips
- Note ligamentum flavum removal and dural pulsatility as markers of adequate decompression
- Document cervical alignment: lordotic alignment maintained (laminoplasty and laminectomy-alone require lordosis; fusion locks in alignment, good or bad)
- If fusion added, document lateral mass screw technique (An, Magerl, or Roy-Camille — specify which) and rod construct; document bilateral vs. unilateral
- Document neuromonitoring baseline and any intraoperative signal changes — MEP/SSEP changes require immediate documentation and response protocol
- C5 palsy (5-11% with laminectomy+fusion): document baseline deltoid and biceps strength preoperatively; any new postoperative weakness should be charted against this baseline
Documentation & Reimbursement Considerations
- Report Posterior Cervical Laminectomy as the primary service when it is the definitive operation performed.
- When posterior fusion is added, bill the fusion code in addition to the decompression code. They are not bundled.
- 90-day global period: physical therapy, collar management, and routine wound checks are bundled. Any MEP/SSEP changes must be documented in real time in the operative note.
