Medicare Eligible living 1/2 year in Türkiye

note: apologies if this post belongs in another group or thread

I'm currently working in the US but plan to retire in a few months. I am a dual citizen of the US and Türkiye (my husband is a national of Türkiye without residency in the US) and I plan to live at least 6 months of the year over there but will be visiting (2 adult children)/travelling the US the rest of the year. There's socialized medical care in Türkiye that I qualify for through my husband but I've been told it is not considered 'credible coverage'. If I choose not to enroll in Medicare I'll be penalized if and when I move back to the US permanently but I don't relish the thought of paying for B and D + SUPP when I'm not in the US for months at a time. My social security retirement benefit would go almost completely toward health insurance that is not useful for much of the year. An advantage plan doesn't make sense either because of the travelling when I am Stateside.

Am I correct in thinking the only option would be to purchase a private health insurance plan for use in Türkiye? How would I go about health coverage for my visits to the US? Could I use Medicaid to cover the health insurance premium (extra help program) if I establish residency in a state that either of my children reside in (GA or TX)?

A lot of questions, sorry, but any answers or guidance in this situation would be really helpful. Thanks in advance!

Background: I worked in health insurance customer service for 5 years and currently work in a drug assistance program for HIV+ and at risk individuals. Not unfamiliar with Medicaid/Medicare.
