Z298 – Examination under general anaesthetic of nasopharynx for malignant disease
OHIP Respiratory Surgical Procedures Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
This service covers an examination under general anaesthesia (EUGA) of the nasopharynx, which may include the oropharynx, oral cavity, and hypopharynx, for the evaluation of malignant disease. This procedure includes any biopsies performed during the examination. This is an Independent Operative Procedure (IOP), meaning it is subject to the specific pre- and post-operative care rules outlined on page of the Schedule of Benefits. It is explicitly not payable if rendered in conjunction with a tonsillectomy, adenoidectomy, or quadroscopy.
Since there is no basic unit value listed for an assistant ('Asst'), assistant services, when required, are claimed using M400B. This service is only eligible for payment upon authorization by a medical consultant following submission of a letter from the surgeon outlining the reason the assistant was required. The number of basic units is that listed under 'Anae' (6). See .
