Federal authorities are on the hunt for a Fullerton woman who they say is involved in a scheme to defraud Medicare of millions of dollars. Ji Have Kim, 43, of Fullerton is the woman they are looking for.

Kim, a registered nurse worked for GreatCare Home Health Inc., a Los Angeles based home health care company. Authorities allege Kim prepared false forms for Medicare home health care patients and falsified nursing notes to look as though she was visiting the patients when she in fact was not.

The insurance fraud scheme first came to light when a former employee filed a whistle-blower lawsuit against the company and Hee Jung Mun, the owner, in 2010. In 2011, Kim pleaded guilty to conspiracy to commit health care fraud and was out of custody pending sentencing. Kim never showed up for sentencing. Mun was sentenced to 57 months in prison.
