How did you manage continuity of care when changing insurance?

I was diagnosed with gastroparesis at Mayo in Arizona in August of last year. To be brief, after following all recommendations I got a GJ tube in May, which has at least stopped the weight loss, but am still severely nauseated daily.

Three months ago I started have severe muscle tension (fishing line tightness) on the right side of my body, along with pain and weakness in my right calf, which has since spread to all my limbs.

I’ve already received a clear MRI at a local facility, and am scheduled for more testing at Mayo in November, but my Cobra coverage is going to expire before then.

Everything we’ve been able to find on the health exchange marketplace puts anything out of state (Mayo) out of network. Does anyone know of/have recommendations for elsewhere to look for private coverage for an individual? It’s overwhelming to think of having to start care over somewhere else in state and start with new doctors in a totally different system.
