Coding references
Neurosurgery: the codes and the rules.
Three tables for a neurosurgical practice, each one a coder can check against the 2025 CMS and ICD-10-CM files, and the notes that come up every week.
The tables.
The notes a coder repeats.
- Spine fusion codes are reported per level, with the interbody, instrumentation and bone-graft codes as add-ons on the same claim.
- The 90-day global on a craniotomy or fusion starts the day before surgery: the decision-for-surgery visit the day before needs modifier 57.
- Discectomy and fusion at the same level on the same day are bundled by NCCI edits; read the edit before adding modifier 59.
