BOSTON — A Lynn woman who allegedly stole more than $490,000 from MassHealth by submitting fake travel reimbursements was released on personal recognizance Thursday, Attorney General Martha Coakley announced in a press release.

“An investigation revealed that from October 2003 to July 2012, (the defendant) fraudulently entered reimbursements credited to her family members into a MassHealth database,” Coakley said. “These fraudulent entries allegedly led to the Commonwealth issuing more than $490,000 in checks made payable to those family members. According to authorities, (the defendant) either deposited these checks into her bank account or the checks were cashed upon receipt.”

Marilyn Beltran, 42, of Lynn, was arraigned in Suffolk Superior Court on seven counts of presentation of false claims and larceny over $250.

MassHealth is a public health insurance program for low- to medium-income Massachusetts residents.

Beltran was a transportation specialist at Maximus, a private company contracted by the state to administer MassHealth’s transportation programs, Coakley said. Beltran’s main responsibility was to enter travel reimbursement information for patients who needed financial assistance to travel to medical appointments, Coakley said.

Maximus began an internal investigation and then referred their investigation to the attorney general’s office in July 2012.

Authorities also allege that Beltran’s longtime partner, Elui Matos, 43, and also of Lynn, participated in the scheme and cashed fraudulent checks he received from Beltran. He was indicted by a Suffolk County Grand Jury on charges of presentation of false claims and larceny over $250, according to officials. He is scheduled to be arraigned in Suffolk Superior Court on Jan. 31. Beltran is scheduled to return to court March 1.

Maximus has offered restitution for losses due to the actions of their former employee and has worked with MassHealth to “tighten internal controls to ensure this doesn’t occur again,” according to the press release.
