Our opinion: If the state itself minimizes fraud in Medicaid, what hope is there of controlling its costs?The challenge for New York’s $62 billion Medicaid program has long been to root out waste, fraud and abuse. But what to do when it’s the state that’s perpetrating all three?Several current and former public employees allege that the state pressured them to make it look as if there was less fraud in the program than they were finding in an audit. As a result, close to $1 billion worth, or more, may have gone unaddressed. Talk about waste, fraud, and abuse of public trust.
