At least 9 Indian medical professionals are among 90 people charged in the US in a massive healthcare fraud under which false claims to the tune of USD 295 million were submitted to public insurance provider.

A nationwide takedown by 'Medicare Fraud Strike Force' operations in eight cities resulted in charges against 91 defendants for their alleged participation in Medicare fraud schemes, the US Justice Department said today.

"The defendants charged in this takedown are accused of stealing precious taxpayer resources and defrauding Medicare -- jeopardising the integrity of our healthcare system and our nation's most critical healthcare programme for personal gain," Attorney General Eric Holder said.

In Chicago, owner of a clinic that provided chiropractic, medical and physical therapy services, Neelesh Patel was charged with 15 counts of healthcare fraud.

In Detroit, among those charged include Rehan Khan, Javed Rehman, Tausif Rahman, Janaki Chettiar, Jigar Patel, Hetal Barot and Srinivas Reddy. Ram Chand Ramrup, owner of an assisted living facility was charged in Florida.

The 91 defendants charged are accused of various healthcare fraud-related crimes, including conspiracy to defraud the Medicare programme and money laundering.

The charges are based on a variety of alleged fraud schemes involving various medical treatments and services such as home healthcare, physical and occupational therapy, mental health services, psychotherapy and durable medical equipment.

Collectively, the doctors, nurses, medical professionals, healthcare company owners are accused of conspiring to submit a total of approximately USD 295 million in fraudulent billing.

According to court documents, the defendants allegedly participated in schemes to submit claims to Medicare for treatments that were medically unnecessary and often never provided.

In several cases, patient recruiters and other co-conspirators were paid cash kickbacks in return for supplying information to providers, who then submitted fraudulent billing to Medicare for services that were unnecessary or never provided.

From Brooklyn to Miami to Los Angeles, the defendants allegedly treated the Medicare programme like a "personal piggy bank", Assistant Attorney General Lanny Breuer said.
