CPT code 63300: Vertebral resection, cervical, extradural, single segment2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 63300 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 63300 covers

This operation removes a cervical vertebral body through an extradural route to relieve pressure on the spinal cord or cervical nerve roots. A neurosurgeon or orthopedic spine surgeon typically performs it in an operating room, for example, to remove an extradural vertebral tumor that requires body resection. The decompression is part of the resection service.

Report 63300 for one cervical vertebral segment when the operative report supports extradural resection and neural decompression. Document the cervical segment, extradural route, extent of vertebral-body removal, and structures decompressed. Code 63308 is the add-on for each additional vertebral segment when applicable. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted. The anatomy is not reported bilaterally with modifier 50.
