Ricky Alardo, a homeless alcoholic, swigs cheap vodka by day at his favorite corner in Washington Heights, then calls an ambulance to chauffeur him to the hospital for a free meal and a warm place to sleep, courtesy of taxpayers who fund his Medicaid benefits. For a chronic caller like Alardo -- who phones 911 four or five times a week -- the annual medical bill can be as high as $300,000. Over 13 years, the length of time he has been abusing the emergency room, he has cost the medical system an estimated $3.9 million.
