Every reasonable effort
Every reasonable effort means that we will make an initial request for evidence from your medical source or entity that maintains your medical source's evidence, and, at any time between 10 and 20 calendar days after the initial request, if the evidence has not been received, we will make one follow-up request to obtain the medical evidence necessary to make a determination. The medical source or entity that maintains your medical source's evidence will have a minimum of 10 calendar days from the date of our follow-up request to reply, unless our experience with that source indicates that a longer period is advisable in a particular case.
