Clinical Context
A 58-year-old male presents with progressive neck pain, right-sided radiculopathy into the upper extremity, and intermittent hand numbness despite 6–12 weeks of conservative management including physical therapy and epidural steroid injection. Imaging (cervical MRI) demonstrates a herniated C5–C6 disc with significant foraminal stenosis and nerve root compression. The spine surgeon elects to perform an anterior cervical discectomy and fusion with arthrodesis at C5–C6 and placement of interbody graft and anterior cervical plate. The patient is admitted from the ambulatory surgery center or hospital-based operating room, receives general anesthesia, intraoperative neuromonitoring as indicated, and postoperative monitoring in the PACU with discharge planning for home or inpatient admission based on comorbidities.
Clinical workflow steps:
-
Preoperative evaluation including history, focused neurologic exam, and review of prior imaging.
-
Informed consent and anesthesia evaluation.
-
Operative procedure: anterior cervical approach, incision in the anterior neck, discectomy at the target level, removal of osteophytes, decompression of the spinal cord and nerve root, placement of interbody device and bone graft, and anterior plate fixation; if fusion is performed for an additional vertebral level in the same encounter, 22552 applies for that additional level.
-
Intraoperative documentation of levels treated, implants used, estimated blood loss, and any intraoperative complications.
-
Postoperative care: PACU recovery, pain control, wound care instructions, and follow-up imaging and clinic visit scheduling.
Typical site of service: hospital operating room or ambulatory surgery center.
Service type: surgical, spine arthrodesis (anterior cervical fusion) operative service.
Coding Specifications
| Modifier | Description | When to Use |
|---|
22 | Increased procedural services | Use when the work or complexity of the fusion is substantially greater than typical and well documented (eg extensive additional dissection, prolonged time). |
23 | Unusual anesthesia | Use when general anesthesia is not used because of an unusual circumstance but procedure performed (rare for this code).
26 | Professional component | Use when only the physician professional component is billed separate from facility/technical component (typically not used for global surgical CPTs).
51 | Multiple procedures | Use when multiple distinct procedures are performed during the same operative session in addition to the fusion.
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned and documented.
53 | Discontinued procedure | Use when procedure is started but discontinued for extenuating circumstances.
62 | Two surgeons | Use when two surgeons work together as primary surgeons for a complex fusion and documentation supports co-surgery.
66 | Surgical team | Use when a surgical team (multiple qualified surgeons) is required and documented for the procedure.
77 | Data not provided | Data not provided in the input.
79 | Unrelated procedure/service by same physician during postoperative period | Use when an unrelated procedure is performed by the same surgeon during the global period.
80 | Assistant surgeon | Use when an assistant at surgery (eg general assistant) is required and billed.
81 | Minimum assistant surgeon | Use when a minimal assistant provides limited assistance and is billed.
82 | Assistant surgeon (when qualified resident not available) | Use when assistant is required because a qualified resident is not available.
AS | Physician assistant, nurse practitioner, or clinical nurse specialist service | Use when an advanced practice clinician performs the service under appropriate state law and payer rules (billed per payor guidance).
