Cardiologist admits to $19 million conspiracy

Prosecutors say he falsely diagnosed many of his patients, including patients with ordinary private health insurance as well as Medicare and Medicaid coverage, with coronary artery disease and debilitating angina so he could treat them unnecessarily, according to a document filed with the U.S. District Court in Newark, N.J.

The $19 million damages total includes only the amounts paid by Medicare and Medicaid. Authorities did not give an estimate of the losses incurred by private insurers in the court document.

They say he also prescribed treatment in cases in which doing so subjected the patients to risk of injury or death.

Katz is scheduled to be sentenced July 23.
