The largest prosecution of a home health-care agency in Virginia ended in guilty pleas from a Glen Allen woman today in federal court.

Rina Zavelsky, 40, a nurse, and her company, Renaissance Inc., pleaded guilty to one count of conspiracy to commit health-care fraud before U.S. District Judge Richard L. Williams.

They will be sentenced on Oct. 24. Zavelsky faces a maximum of 10 years in prison and a $250,000 fine. Renaissance faces a fine of up to $500,000.

As part of the plea agreement Zavelsky's husband -- physician Ilya Zavelsky, 46 -- was dismissed from the case. Their company provided respite care and other services to Russian-speaking communities in Virginia.

They were indicted earlier this year for conspiracy to commit health-care fraud and money laundering. In pleading guilty yesterday, Mrs. Zavelsky admitted she defrauded Medicaid by submitting false claims for payment.
