I’ve had that impression about LADA too, some people going years from initial “issues”, often leading to a T2 DX and then migrating to T1 over time. I haven’t seen that many kid histories of diabetes happening that way.
Re the codes, I agree that they have shortcomings but one that is really critical is that coverage follows codes in many cases. I don’t agree that T2 should be short supplied but they are.
My solution to that would be to make blood sugar testing a civil right. I don’t think anyone does it for fun and even an OCD can only test so much. Just let us test and see what happens. I don’t see it causing a public health crisis and I think that it would be a healthier way to approach testing and management of costs. The money insurers pay out could very well be saved to the system by relieving doctors from the hassle of writing stupid “letters of medical necessity” for their patients, insurers from having armies of nurses redlining test strips, etc. Put those resources into care, not the sort of “Crimson Mutual Assurance” scenarios this whole song-and-dance seems like to me.
