N163 – Morcellation procedure - multiple sutures
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
N163 is a surgical procedure listed in the Musculoskeletal System section of the Schedule. The service is eligible for payment to the primary surgeon (using suffix A). Surgical assistant services (suffix B) and anaesthesiologist services (suffix C) are also eligible for payment and are calculated by summing basic units and time-based units as detailed in the General Preamble (- for assistants, - for anaesthesiologists). Various premiums may apply, such as those for after-hours services (E409, E410), trauma cases (E420), and specific patient age groups.
When to Use
- Use N163 specifically for musculoskeletal morcellation procedures requiring multiple sutures when no other more specific surgical code applies.
- Use this code for the primary surgeon (suffix A) when performing the procedure in a hospital setting where the complexity of the morcellation and suturing meets the criteria for this specific fee.
Common Pitfalls
- Billing N163 in conjunction with other surgical codes for the same anatomical site without ensuring the services are not considered 'included' or 'incidental' under the General Preamble.
- Failing to document the specific necessity of the multiple sutures, which is a defining component of the N163 procedure description.
Billing Tips
- Ensure the surgical report clearly details the morcellation technique and the placement of multiple sutures to support the use of N163 over less specific musculoskeletal codes.
- Always verify if the procedure qualifies for age-based premiums or trauma premiums (E420) based on the patient's age and ISS score at the time of service.
