Opioid crackdown involves scores of US doctors

More than 160 have been charged with fraud

Scores of doctors in the US, along with nurses and pharmacists, have been charged with healthcare fraud in a co-ordinated operation across the country.

Last week, the US Department of Justice announced charges against 601 healthcare workers, including 162 doctors, for their role in the systemic fraud that resulted in more than US$2 billion in losses.
