1. The time that has elapsed since the last change was made in the customary charge
This involves finding out how long it has been since the last change, and if the physician or supplier has had a change in customary charge for the service in the past two or three years. The more time that has elapsed since the last change, the stronger the case is for recognizing the current change.
Where the physician or supplier states not previously increase fees because of the government’s request for restraint in this regard, and the carrier can verify this through its claims records and/or information furnished by the physician or other person, it may take this factor into account in determining whether unusual circumstances are present in a particular case.
