Sleep-deprived/induced EEG
    A sleep-deprived/induced EEG is an EEG recording (with or without video monitoring)
    performed after an overnight period of sleep deprivation of greater than 4 hours; or the
    administration of a sedative/hypnotic agent prior to the EEG recording for the purposes of sleep
    induction, and must include all of the following:
       a.at least 60 minutes of EEG recording time;
       b.a minimum of 16 channels of EEG; and
       c.recordings of at least two physiological parameters.

   EEG with time-locked video recording
     An EEG with time-locked video recording must include all of the following:
    a. at least 30 minutes of EEG recording time;
    b. a minimum of 16 channels of EEG;
    c. recordings of at least two physiological parameters; and

   Note:
   1.The amount payable for a sleep-deprived/induced EEG, or an EEG with time-locked video
     recording that does not meet the above requirements will be reduced to that for a routine
     EEG fees (i.e. G414 and G415/G418).
   2.G414 is not eligible for payment with G541.
   3.Only one of G415, G418, G543 or G496 are eligible for payment per day.

Repeat diagnostic study
                                    “Repeat diagnostic study” means an overnight diagnostic sleep study rendered:
                                   a. for the purpose of obtaining a second opinion at a different facility than the facility where the
                                      preceding study was rendered, provided that the following conditions are met:
                                             i.   prior to the repeat diagnostic study, the patient has been assessed by a physician who
                                                  practices sleep medicine at the different facility,
                                          [Commentary:
                                          The different facility requirement above applies to a repeat diagnostic study rendered at a
                                          hospital, a hospital off-site premise or an ICHSC.]
                                             ii. where the previous study was rendered at an ICHSC and the repeat diagnostic study is
                                                 rendered at a different ICHSC (the “different facility”) than the ICHSC where the
                                                 preceding study was rendered (the “first facility”), neither the owner nor the operator of
                                                 the different facility is, at the time the repeat study is rendered, an associate of the
                                                 owner or operator of the first facility, where “associate” has the same meaning as in the
                                                 Integrated Community Health Services Centres Act, 2023; or
                                          b. for one or more of the following purposes, after pre-study assessment by a physician
                                             practicing sleep medicine:
                                             i.   re-evaluation of a previous negative or inconclusive diagnostic sleep study as indicated
                                                  by persistent or progressive symptoms;
                                             ii. re-evaluation, other than primarily for Positive Airway Pressure therapy (PAP)
                                                 adjustment, of patients previously diagnosed with a primary sleep disorder in which
                                                 there has been symptom development suggesting another co-morbid sleep disorder; or
                                             iii. re-evaluation of patients with an established diagnosis of a sleep disorder other than a
                                                  sleep related breathing disorder who have significant symptom progression or non-
                                                  response to therapy.

                                          1.In the case of patients with previously diagnosed sleep related breathing disorders, although
                                            PAP treatment may be adjusted during a repeat study, a repeat study is not eligible for
                                            payment if rendered primarily for PAP treatment adjustment.
                                          2.Examples of sleep disorders other than a sleep related breathing disorder are Narcolepsy,
                                            Idiopathic hypersomnia and Periodic Limb Movement Disorder.]

                                          Subject to the prior approval requirements, an additional therapeutic study in excess of the

                                          Note:
                                          1.For payment purposes, repeat diagnostic studies or therapeutic studies for indications or in
                                            circumstances other than listed above, or in excess of the limits set out above require prior

                                            physician practicing sleep medicine, is not eligible for payment.
                                          3.A therapeutic study rendered without a pre-study assessment by a physician practicing sleep
                                            medicine is not eligible for payment except:
                                             a.For the therapeutic study that immediately follows an initial diagnostic or repeat
                                                diagnostic study where:
                                                 i. the time interval is such that it is unlikely the clinical circumstances of the patient has
                                                     changed; and
                                                 ii. the physician practicing sleep medicine has previously assessed the patient and
                                                     documented the applicable decisions with respect to the performance of the

                                             b.In exceptional circumstances where the physician can demonstrate to the ministry upon
                                                request that the CPSO standards are satisfied with the use of a clinical protocol or
                                                approved medical directive.

                                          1.An example of an exceptional circumstance may be where a patient is required to travel a
                                            long distance to a sleep facility and requires an initial diagnostic or repeat diagnostic study
                                            followed by a therapeutic study on a subsequent night. For payment purposes, a pre-study
                                            assessment by a physician practicing sleep medicine is not required provided the therapeutic
                                            study is rendered in accordance with a clinical protocol or medical directive that has been
                                            approved by an authority other than a physician affiliated with the sleep facility (e.g. a
                                            Medical Advisory Committee for a sleep clinic affiliated with a hospital). The physician should
                                            be prepared to provide any necessary supporting documentation to the ministry upon
                                            request.
                                          2.Prior approval, where required, will typically be dependent on the physician demonstrating
                                            that the study is generally accepted as necessary for the patient under the circumstances.
                                          3.Sleep studies that require prior approval also require a pre-study assessment by a physician
                                            practicing sleep medicine. It is this assessment upon which the request for prior approval is
                                            considered.
