There are many different documents that you may wish to have in your arsenal when it comes to preparing for your future. One of these, for example, is referred to as a healthcare power of attorney which allows a trusted individual to make decisions on your behalf about your medical treatment if you become unable to do so on your own. Only medical powers are granted in this document rather than financial powers. However, you may want to also consider a HIPAA release. 
This is one of the most important documents to keep a copy of with all of your other estate planning materials. The health insurance portability and accountability act of 1996 outlines that medical records have to be kept confidential. It can also have unintended consequences, however. Without the legal ability to share medical records, it could be challenging for your family to get critical information about your treatment and medical condition if you become incapacitated.
A HIPAA release will allow your medical providers to give this information to your loved ones in the event that something happens to you. The documents you have set aside for health purposes may be beneficial to your family members if something unexpectedly happens to you. Although these are difficult topics to consider, thinking about them in advance can help you with a broad range of estate planning goals and needs.
