In special cases where the attendance of more than one anesthetist is medically necessary, the benefit which may be claimed by each anesthetist shall be 100% of that listed for the procedure. The decision as to whether a second anesthetist is required for a procedure lies with the primary anesthetist. In cases where the primary anesthetist determines a second anesthetist is required, claims from both anesthetists must be submitted with text explaining the necessity for two anesthetists.
