Z313 – Endoscopic transnasal ligation of the sphenopalatine artery for posterior epistaxis - unilateral
OHIP Psychiatric Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Performs an endoscopic transnasal ligation of the sphenopalatine artery to treat posterior epistaxis on one side. As an Independent Operative Procedure (IOP) indicated by the 'Z' prefix, specific rules for pre-operative assessments apply (see ). This service is marked with a '#' symbol, indicating that when performed in a hospital or ICHSC, the facility costs (premises, equipment, supplies, personnel) are funded through the hospital's global budget or other facility funding, and not by the physician fee (see ).
When to Use
- Use Z313 for the definitive surgical management of intractable posterior epistaxis via endoscopic ligation of the sphenopalatine artery.
- Use this code when the procedure is performed unilaterally; if performed bilaterally, Z313 is claimed for the first side and Z313 with the bilateral reduction rule (85% of the fee) applies to the second side.
Common Pitfalls
- Attempting to bill an assessment or consultation on the same day as Z313 is a common rejection; as an IOP, the pre-operative assessment is bundled into the surgical fee unless specific criteria for a separate visit are met.
- Billing for a surgical assistant (Z313B) will result in a rejection because there are no assigned basic units for an assistant in the Schedule of Benefits for this procedure.
Billing Tips
- Ensure the procedure is documented as a non-elective surgical intervention to qualify for after-hours premiums like E409 or E410 if performed outside standard operating hours.
- If the patient is under 16 years of age, remember to append the appropriate age-based premium (e.g., AGE_PREMIUM_UNDER_16_YEARS) to maximize the procedural fee.
