CHARLES CITY --A Charles City man is accused of forging signatures to bill the state for fraudulent Medicaid payments for more than a year.

Michael Joseph Koster, 56, is charged with felony forgery, misdemeanor third-degree fraudulent practice and misdemeanor tampering with records.

Between Dec. 18, 2016, and Jan. 1, 2017, in Floyd County, Koster is accused of intentionally forging another person's signature on five respite notes, court documents said.

Each note was then submitted for payment of Medicaid-covered services, according to court documents. This was done without the knowledge or permission of the individual whose name was signed.

Court documents said Koster submitted documentation to bill the state for $748.24 in services he did not provide and created false records.

A Charles City police officer arrested Koster on a warrant during a Jan. 22 traffic stop.

Koster was released from the Floyd County Jail Jan. 23. He signed a promise to appear in Floyd County District Court Feb. 21.
