E384C1/C2 screw fixation

OHIP Surgical Assists Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits

Posterior spinal arthrodesis of / using screw fixation (transarticular, pedicle, or lateral mass). This procedure is performed with instrumentation by the same surgeon and is claimed in addition to a primary procedure such as N509, N510, N560, N561, or N572.

When to Use

  • Use as an add-on code when performing posterior spinal arthrodesis of C1/C2 with screw fixation (transarticular, pedicle, or lateral mass) during a primary procedure such as N509, N510, N560, N561, or N572.
  • Use when specifically performing the C1/C2 fixation component of a more extensive cervical spinal fusion procedure.

Common Pitfalls

  • Claiming E384 as a standalone procedure; it is strictly an add-on and will be rejected if not billed with one of the specified primary codes.
  • Incorrectly billing E370 in conjunction with E384, which will trigger an automatic reduction of E370 to the lower-valued E366.
  • Attempting to claim E366, E371, or E377 for the C1/C2 level itself; these codes are reserved for additional levels beyond the primary E384 fixation.

Billing Tips

  • Ensure the primary procedure (e.g., N509) and the add-on E384 are submitted on the same claim to avoid rejection.
  • When fusing additional levels beyond C1/C2, select the appropriate add-on (E366 for standard levels, E371 for occiput, or E377 for cervico-thoracic junction) to ensure correct reimbursement.
