@sungo me too.
I did change insurance for 2026 and it's been a LOT better for me. Not just in funding care, it's a smaller insurer based in my state and communication and customer service has been excellent. There a small $30 snafu and three people are working on it and providing status updates.
@sungo similar to @semifor, when my father was seeing many specialists, each wanting to only consider their own areas of expertise, his internal medicine physician coordinated all care. She was special, though. She'd been my doc previously, and I'd recommend her to my parents some years before.
As I age, I still have an internist, and also 7 or 8 specialists I see. As far as coordination goes, my rheumatologist always reaches out to the internist's clinic for recent lab results before ordering anything, every time I visit. He's the only one who appears to actively communicate with the internist about me. My cardiologist recently recommended a medication, and as I was seeing the internist later that day, he suggested I discuss it with the internist, as he didn't feel comfortable prescribing it without consultation. Everybody else? They do their own thing.
