Explanation
Updated October 26, 2026
Neurocognitive testing of at least 46 minutes by a geriatrician, neurologist or psychiatrist, covering memory, attention, language and more.
What it covers
An extended specific neurocognitive assessment is an assessment of neurocognitive function, done personally by the physician, that tests memory, attention, language, visuospatial function and executive function (A58).
At least 46 minutes (consecutive or not) must be spent only on this service, including giving and scoring the tests, all on the same day. Acceptable batteries include the Toronto Cognitive Assessment (TorCA), or the BNA short form plus MoCA or plus FAB. MoCA, BNA-SF or FAB alone is not enough (A58).
