Can a medical facility deny treatment based on an anonymous accusation of substance abuse? Recently I sought treatment at my doctors clinic from an after hours service called 'express care'. I've seen express care doctors in the past, and while unpleasant, they are still nice to see during an asthma attack. While I was suffering from an asthma attack on this occasion, the nurses told me that I can't be seen, when I explained that I was currently having an asthma attack, they told me that it's ok to refuse anyone at any time for any reason. Their words, not mine. I went to the e.r. At the hospital across town (same corporation), they told me after almost 2 hours there during an asthma attack that I can't be treated because they received 'an anonymous call' alerting them that I 'like to abuse' my medications and therefore do not need to be treated. Needless to say I felt a lot of emotions including a great deal of anger and confusion. I believe I know who called the tip in to them, although have no evidence to support my suspicions. What I would like to know is this; can a medical facility legally turn me away based on an anonymous accusation, and what recourse do I have? Do I have Any rights in this instance? Can I press charges against this accuser, and naturally, do I have the right to the identity of the accuser?
