CareOregon Connect to Care

What is Connect to Care? And how can it help your patients?

We all know that Medicaid and the Oregon Health Plan (OHP) can be complicated, but we’re here to help make it easier for current and prospective members. How do we do that? With Connect to Care, CareOregon’s community outreach program.

You might have seen or heard of Connect to Care before, when it was called goMobile. But we changed the name so that it’s easier to understand what we’re all about – connecting people with the care they deserve.

Every month, Connect to Care comes out to the communities where your patients live, all over the Metro area – including Clackamas, Multnomah and Washington counties. We find out if they have Medicaid, and if they don’t, we can help them get signed up for it through the Oregon Health Plan. That means they can get physical health care, but also dental and mental health care, too.

And if they already have health insurance through OHP, we can help them manage their health care.

There are lots of things Connect to Care and our partners are here to help your patients with:
