For many people struggling with opioid use, a key to success in recovery is having support. Some are getting that support from an unlikely place: their health insurer.

Amanda Jean Andrade, who lives west of Boston in a halfway house for addiction recovery, has been drug- and alcohol-free since October. It’s the longest she’s been off such substances in a decade. She gives a lot of the credit for that to her case manager, Will — who works for her insurance company.

“Having Will is the best thing in the world for me,” Andrade says. “Because if I have the slightest issue with anything to do with my insurance that includes, like, prescriptions — even when I had a court issue — I know that I can call him.”

Andrade’s insurer is CeltiCare Health Plan, one of several health insurance companies in Massachusetts taking aggressive new steps to deal with the growing opioid epidemic. CeltiCare has about 50,000 members in the state, and mostly manages care for patients on Medicaid. To read more from DEBORAH BECKER.
