I am retired military, and have been very careful to keep track of my own records. I usually ask my doctors to give me copies.
Most doctors willingly hand over the information, but some steadfastly refuse.
I say that the records are about me, and I'm entitled to a copy. Both sets of laws generally operate in your favor and give you legal access to your medical records. Federal regulations adopted by the Department of Defense require your medical records to be disclosed to you under ordinary circumstances. The records themselves are the property of the government, but the information must provided when you request it. Even if disclosure could be harmful, DoD regulations require the medical records be forwarded to any other physician you specify.
