If you haven't been put into a managed care plan, and still truly have the open card, then the Natural Childbirth and Family clinic in North Portland will take your open card. They are nice folks, passionate about natural birth, very flexible and understanding about vaccines. They can ONLY accept the open card though, so if you're on a managed care plan now (or will be very soon), then they wouldn't work. But their website is here:http://www.naturalchildbirthclinic.com/
We are on OHP for another few months and were just placed with Columbia Medical Clinic (but when we moved to Portland we unfortunately couldn't keep our open card). They're relatively new, but they are accepting OHP patients right now. That said, I know NOTHING about them. The only reason I chose them (as opposed to the maybe 5 other clinics in the metro area that I also knew nothing about and who were accepting new OHP patients w/o an open card), was because their website mentions massage therapy and and acupuncture among their services, so I hope (and pray, and hope) that they will be slightly more open to our non-traditional approach to birth and everything since. DS is very selectively vaxed, and I'm a huge germ phobe, so we haven't been in for a visit yet. DS is healthy, and I'm not huge on well baby visits anyway (breastfeeding well, growing well, meeting milestones, no vaxes thank you, so what are they going to tell me really?). But now at least if DS gets sick I have someplace to take him. Their website is columbiaclinic.com, you might try calling them.
I think that Mt. Tabor Family Medical Clinic is also accepting OHP patients at this time. From what I understand they are very much the traditional medical services, party line kind of clinic. But that's pretty much what you're going to find if you are using your LO's OHP benefits.
If you find a doctor you want, and can afford out of pocket, then lie. They will see you if you don't have insurance, but won't see you if you have OHP (even if you can pay cash). It's crazy, but the way it was described to me, was that if they rendered you services, and then suddenly you decided, nope, sorry, not gonna pay, then they wouldn't be able to bill OHP, and wouldn't really be able to force you to pay because you have insurance.
Maddening, isn't it?
