You can read the whole thing here [PDF]. Here are the highlights:
The administration is pushing for doctors and mental health professionals to involved.
PRESERVE THE RIGHTS OF HEALTH CARE PROVIDERS TO PROTECT THEIR PATIENTS AND COMMUNITIES FROM GUN VIOLENCE: We should never ask doctors and other health care providers to turn a blind eye to the risks posed by guns in the wrong hands.
Clarify that no federal law prevents health care providers from warning law enforcement authorities about threats of violence: Doctors and other mental health professionals play an important role in protecting the safety of their patients and the broader community by reporting direct and credible threats of violence to the authorities. But there is public confusion about whether federal law prohibits such reports about threats of violence. The Department of Health and Human Services is issuing a letter to health care providers clarifying that no federal law prohibits these reports in any way.
Protect the rights of health care providers to talk to their patients about gun safety: Doctors and other health care providers also need to be able to ask about firearms in their patients’ homes and safe storage of those firearms, especially if their patients show signs of certain mental illnesses or if they have a young child or mentally ill family member at home. Some have incorrectly claimed that language in the Affordable Care Act prohibits doctors from asking their patients about guns and gun safety. Medical groups also continue to fight against state laws attempting to ban doctors from asking these questions. The Administration will issue guidance clarifying that the Affordable Care Act does not prohibit or otherwise regulate communication between doctors and patients, including about firearms.
In the second paragraph Obama is parsing words. As we noted earlier, Senate amendment 3276, Sec. 2716, part c. to the Affordable Care Act (Obamacare) says:
(1) WELLNESS AND PREVENTION PROGRAMS- A wellness and health promotion activity implemented under subsection (a)(1)(D) may not require the disclosure or collection of any information relating to–`(A) the presence or storage of a lawfully-possessed firearm or ammunition in the residence or on the property of an individual; or`(B) the lawful use, possession, or storage of a firearm or ammunition by an individual.`(2) LIMITATION ON DATA COLLECTION- None of the authorities provided to the Secretary under the Patient Protection and Affordable Care Act or an amendment made by that Act shall be construed to authorize or may be used for the collection of any information relating to–`(A) the lawful ownership or possession of a firearm or ammunition;`(B) the lawful use of a firearm or ammunition; or`(C) the lawful storage of a firearm or ammunition.`(3) LIMITATION ON DATABASES OR DATA BANKS- None of the authorities provided to the Secretary under the Patient Protection and Affordable Care Act or an amendment made by that Act shall be construed to authorize or may be used to maintain records of individual ownership or possession of a firearm or ammunition.`(4) LIMITATION ON DETERMINATION OF PREMIUM RATES OR ELIGIBILITY FOR HEALTH INSURANCE- A premium rate may not be increased, health insurance coverage may not be denied, and a discount, rebate, or reward offered for participation in a wellness program may not be reduced or withheld under any health benefit plan issued pursuant to or in accordance with the Patient Protection and Affordable Care Act or an amendment made by that Act on the basis of, or on reliance upon–`(A) the lawful ownership or possession of a firearm or ammunition; or`(B) the lawful use or storage of a firearm or ammunition.`(5) LIMITATION ON DATA COLLECTION REQUIREMENTS FOR INDIVIDUALS- No individual shall be required to disclose any information under any data collection activity authorized under the Patient Protection and Affordable Care Act or an amendment made by that Act relating to–`(A) the lawful ownership or possession of a firearm or ammunition; or`(B) the lawful use, possession, or storage of a firearm or ammunition.’.
So while your doctor can ask, you don’t have to answer, and if they were to report data about your lawfully owned guns or ammunition they would be breaking the law and could (potentially) be exposed to lawsuits.
