Salvatore Scumace is under investigation into counterfeiting, extortion and violations of the Italian financial police, Guardia di Finanza said at a news conference.
Police have accused Scumace of being “a continual absentee” at the Pugliese Ciaccio hospital in Catanzaro since 2005.
Officials said Scumace had collected more than 538,000 euros ($ 648,000) to pay during his alleged omission campaign.
Police said Scumace and his six superiors were under investigation.
According to police, Scumace extorted his superiors to flee more than a decade and a half from missing work.
The officer checks attendance records, changing duties and receives statements from his colleagues and supervisors.
The lawsuit was discovered as part of a broader investigation into the absence of government employees.
Police told CNN that the Scumace investigation was concluded. He has not been arrested.
Scumace now has 20 days to present a conclusion or to be investigated, police told CNN. Prosecutors will then decide whether to ask for the indictment.
CNN has contacted Scumace’s legal representative, Luca de Munda, who said he did not speak to his clients and was therefore unable to comment.
His supervisor’s investigation was also concluded, police said, and no arrests were made.
