the amount of money you are charged depends on the state you live in. some states allow outrageous charges such as $3.00 a page and a retrieval fee of $20.
for the future, make a file for your husband and everytime he has a test, request a copy of the test results at the time the doctor reviews them with you either in person or by phone. you shouldnt be charged for these at that time. it will save you time and money in the future for disability reviews and any other entity that may need a copy of a particular medical record.
