A former Delaware County podiatrist was sentenced Tuesday to eight years in federal prison after pleading guilty to nearly $5 million in health-care fraud, an amount he must now pay back.

The U.S. Attorney's Office in Philadelphia said Stephen A. Monaco, of A Foot Above Podiatry in Havertown, submitted fraudulent bills to Medicare and Medicaid for that amount for podiatric procedures that were not performed or ones that were not medically necessary between January 2008 and Oct. 31, 2014.

Monaco, 59, pleaded guilty in August to one count of health-care fraud.

On Tuesday, U.S. District Judge Juan R. Sánchez ordered Monaco to serve three years' supervised release and to pay $4,960,295 in restitution, in addition to sentencing him to 97 months behind bars for defrauding Medicare and Medicaid.

Monaco was one of 301 people charged last year in a nationwide Medicare-fraud bust spanning 36 federal districts and involving about $900 million in fraudulent payments.
