How long does a doctor have to give you your medical records?

The below answer is incorrect. The below is the Federal Rule for medical records (and most states have their own rules, many being around 3 years) - billing is not considered part of the medical record, this is specifically stated in both Federal and State rules. There is not a requirement for retaining billing information, most practices do not keep copies of billing information more than 90 days.

Seven years for adults, and childrens' charts need to be kept until they are twenty one. Although many offices have switched them over to an image on their hard drive in order to save space. Some saves your data in back up servers. But, wherever you may have any kind of medical record, be sure that you have your own records kept for yourself too.
