Wiki Critical Flicker Fusion Frequency Test

[nwillia3]

Does anyone know the cpt code for this test? I have searched for it. It is also know as flicker perimetry. Thanks in advance for your help.

As with many 'tests' a label is put on it so as to give others who read the chart later an idea of what is being 'tested' without having to resort to a wordy reexplanation. Never heard of this 'test' and not billable as far as I know within pages 470-475 of CPT 2012. (Ophthalmology testing within Medicine Section) An example of this is the Shirmer 'test' for dry eye/epiphoria-look it up on Wikipedia; it is an example of non-billable 'test' in ophthalmology.
