I would ask the Dr. what they are required to report under the Affordable Care act and what codes will be sent to your insurance provider. Tell him you have some concerns over HIPPA and disclosure.
Since alcoholism is self identified and in your past, your are not Alcohol dependent under DSM V, you are not lying here, you are just someone who does not drink. My rationale is pre-existing conditions can have an impact on life insurance and other insurance related issues. If you are not concerned with any of these then by all means simply be forthright with the Dr. - no reason to send him or her on a wild goose chase.
