N575 – Below conus - each level
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure falling under the Musculoskeletal System section of the Schedule of Benefits. As the specific description for `N575 was not provided, this entry is based on general rules applicable to surgical procedures found in the General Preamble.
Payment for this service is made to the surgeon (suffix A), assistant (suffix B), and anaesthesiologist (suffix C). The fees for assistant and anaesthesia services are calculated based on a combination of basic units assigned to the procedure and time units, as detailed in the Surgical Assistants' Services` () and Anaesthesiologists' Services () sections of the General Preamble.
Various premiums may be applicable, including age-based premiums for patients under 16 (), after-hours premiums for non-elective procedures (, , ), and a trauma premium for severely injured patients ().
When to Use
- Use N575 for surgical procedures involving the spinal column below the level of the conus medullaris when the procedure is defined on a per-level basis.
- Select N575 when performing distinct spinal interventions that require individual level-based billing rather than global spinal procedure codes.
Common Pitfalls
- Billing N575 in conjunction with N521 or N522, which are restricted and ineligible for payment when rendered with Spinal Surgical Procedures except for duroplasty (E382).
- Failing to document the specific spinal levels treated, which is required to justify the number of units billed for a per-level code like N575.
Billing Tips
- Ensure that if multiple levels are treated, the claim reflects the correct quantity of N575 services to avoid underpayment or rejection for missing level specificity.
- Always verify if the procedure qualifies for the acute spinal cord injury premium (E383) or spinal duroplasty (E382) to maximize the claim value when clinically indicated.
