Question:

I am a military medical retiree and also rated as TDIU but I don't get my retirement from the military. Why don't I get concurrent retirement disability pay?

I don't know why you aren't eligible for CRDP. Each case is different and there are any number of things that can hang you up.
 

You'll have to look at the rules here https://www.dfas.mil/retiredmilitary/disability/crdp/  and sort this out comparing to your own record. Good luck.
