Usually these are things that just require you to send in documentation--for example, copies of medical records for a condition/treatment you had in the past, so no need to go to the dr. again at this point. But your letter should have been pretty specific about what you need to do. My son had 3 remedials, 2 which didn't require a new appt. just copies of medical records. It was all spelled out in the letter--if yours wasn't, there should be a phone # of someone you can call with questions. I would advise you follow the directions ASAP as these things can take time to get waivered. Good luck!
