About 61783: Computer-assisted spinal surgical navigation
Reports computer-assisted navigation used to guide spinal surgery, such as instrument placement during a fusion or other image-guided spinal operation.
This add-on captures computer-assisted navigation used during an operation on the spine. The surgeon uses imaging and a navigation system to orient instruments to spinal anatomy during procedures such as fusion, deformity correction, or surgery involving a spinal lesion. Orthopedic spine surgeons and neurosurgeons typically perform these operations in a hospital operating room. The navigation service supports the primary operation; it is not the spinal operation itself.
Report 61783 only with an eligible primary procedure, not by itself. The operative record should establish that computer-assisted navigation was used and describe its role in guiding the spinal procedure. It is paid within the primary procedure's global period, so it is not separately reported as a later postoperative service. For example, navigation used during a lumbar fusion may support reporting this add-on with the fusion procedure when coding requirements are met.

61783 billing questions
Can 61783 be reported by itself?
No. It is an add-on for computer-assisted navigation during a primary spinal procedure and must be reported with that procedure.
How is 61783 different from 61781 and 61782?
61783 is for navigation during spinal surgery. Codes 61781 and 61782 describe navigation for cranial procedures, with the distinction based on the cranial surgical context.
What documentation supports 61783?
The operative report should show that computer-assisted navigation was used during the spinal operation and explain how it guided the procedure.
Is 61783 separately reportable after the operation?
No. CMS treats it as an add-on paid within the primary procedure's global period; it is not a separate postoperative service.
Is 61783 the code for the spinal fusion itself?
No. The fusion or other spinal operation is reported with its own primary procedure code; 61783 represents the navigation service used during that operation.
