S900 – Basic units for anaesthesia - unlisted dental surgical procedure
OHIP Digestive System Surgical Procedures Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This fee code represents the basic units for an anaesthesia service rendered in conjunction with any unlisted dental surgical procedure performed by a dental or oral surgeon. The total anaesthetic fee is calculated by adding the 8 basic units to the applicable time units and multiplying the total by the anaesthesiologist unit fee. Refer to the General Preamble (, ) for detailed rules on calculating anaesthesia fees. Claims should be submitted with a 'C' suffix (e.g., S900C).
A pre-anaesthetic evaluation and post-anaesthetic follow-up are included elements of the service and should be documented.
The anaesthesiologist must indicate his/her starting and finishing times as part of the medical record, particularly if a replacement anaesthesiologist is involved.
