Mario Roncal, who posed as a physician as part of a $19 million Medicare fraud scheme, draws 8 months of house arrest and must pony up the nearly $590,000 in restitution.

An accomplice in the largest Medicare fraud scheme in New Jersey history was sentenced yesterday to 8 months of house arrest and ordered to pony up nearly $590,000 in restitution, according to court documents.

Mario Roncal was a key part of the scheme designed by prominent New Jersey cardiologist Dr. Jose Katz, who was sentenced last week to 6½ years in prison and ordered to repay the $19 million in fraudulent reimbursements he reaped.

Katz was co-founder and CEO of a pair of cardiology and internal medicine businesses in New Jersey and New York, according to court documents.
