If you should have a medical provider ask you this question tell them they do not have the authority to ask. Tell them to look at sect. 2717 of the Affordable Care Act ( obummer care). The info is in the in the Wellness and Prevention Programs. It states that it may not require the disclosure or collection of any information relating to... the presence or storage of a lawfully-possessed firearm or ammunition in the residence, or on the property of an individual: or the lawful use, possession, or storage of a firearm or ammunition by an individual.
Most people and darn few of our elected officials have read this Act, it is well over 2,000 pages and the biggest bunch of gobblygook I have ever tried to read.
