Need advice: 'Obama Care' and an almost homeless freind.

My freind lives in a trailer out in my back yard. He has no source of income currently although he does under the table handiwork when and where he can find it. He is 60 years old, he has never had medical insurance. Furthermore he is very stubborn, (cranky old fart) and never takes advice from freinds.

A few days ago he was sitting on the dock of a nearby lake fishing. While fishing he left his feet in the water and they got horribly sunburnt. Predictably he refused any advice we had (get to an ER) and figured to tough out the burn.

The next day his feet swelled up to the point his ankles disappeared. The swelling is down but the blisters that covered the entire tops of both feet have ruptured. Both feet look horrible-he can not walk because of this. IMO he needs medical attention. He claims that he is ineligible for any medical attention.

I'll let this OP soak for a bit but what i hope for is advice. We live in Washington State. What resources can he actually take advantage of? Is there any coverage from the ACA that he can ask for? If so will he get charged for not signing up for it before all this happened to him?

Not seeking medical advice here, IMO he needs to get to a doctor and I want to present him with options. Thanks
