Single-level cervical total disc arthroplasty via anterior approach, including discectomy, endplate preparation, osteophytectomy for nerve root or spinal cord decompression, and microdissection — one interspace only.

Documentation requirements

What must appear in the operative or office note to support the claim.

Source · Editorial brief grounded in 6 cited references ↓

• Specify the exact interspace treated (e.g., C5-6) — 'cervical disc replacement' alone is insufficient for audit purposes
• Confirm anterior approach documented by name in the operative note
• Document discectomy with endplate preparation and any osteophytectomy performed for nerve root or spinal cord decompression
• Record the implant used: manufacturer, device name, lot/serial number, and size — required for ASC pass-through and commercial implant carve-out claims
• Include preoperative imaging (MRI or CT) demonstrating the pathology (degenerative disc disease, disc disruption, disc desiccation) with correlation to symptoms
• Document failed conservative management duration and modalities prior to surgery — most payers require 6 weeks minimum
• Note neurological examination findings pre- and postoperatively to support medical necessity
• If modifier 22 is applied, document specifically what increased the work beyond the standard procedure (e.g., significant scar tissue, anatomical anomaly, prolonged operative time with reason)

RVU & reimbursement

Component RVUs and Medicare national rate. Actual payment varies by GPCI locality.

Payment by site of service

Medicare pays different rates by setting. HOPD typically pays substantially more than ASC for the same procedure.

Common denial reasons

The recurring reasons claims for CPT 22856 get rejected.

Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓

• Missing or expired prior authorization — this is the top denial trigger for cervical arthroplasty at commercial payers
• Insufficient documentation of failed conservative care before surgery
• 22551 billed alongside 22856 — the discectomy and decompression are bundled into 22856 and cannot be separately reported
• 76000 (fluoroscopy) billed separately — fluoroscopy is included in all open spine surgical codes and is not separately reportable
• Multiple units of 22856 billed for a multilevel case instead of 22856 + add-on code +22858
• ICD-10 diagnosis code does not support cervical arthroplasty medical necessity (e.g., using a code for cervical sprain rather than degenerative disc disease or radiculopathy)
• Procedure performed on a patient outside payer-defined age or clinical criteria (some MACs and commercial payers have LCD/coverage policies restricting cervical arthroplasty to specific indications)
