Can a person enroll in Oregon Health Plan if they are claimed as a dependent by someone else?

I am wondering if a person can enroll in Oregon Health Plan as an individual if they are claimed as a dependent by someone else. EDIT: assume the person is over 18 years old.

I am guessing the answer is no, but I can't find any definitive statement of that. I've looked at various web pages and documents, but I haven't found an answer. I have looked at the OHP application itself but they don't specifically address this question.

Thanks in advance for any insight you can give.
