This site lists which and how much which University of Californias (UCs) cover and provide trans* related health services, such as hormones and SRS. Here they are copy/pasted for your convenience (last updated 2009 unless otherwise noted)
UC Berkeley [since 2009-2010 — lifetime max of $75,000 per student]
UC Davis [since 2009-2010 — lifetime max of $75,000 per student]
UC San Diego [since 2007-08 — up to $25,000 annually]
UC San Francisco [since 2008-09 — up to $30k annually]
UC Santa Barbara [since 2005-06 — amount unknown]
UC Santa Cruz [since 2008-09 — lifetime max of $75,000 per student]
This is just a brief list—the link contains more info about co-pays, deductibles, and more coverage. There is also a national list of campus that provide SRS and hormones (Emerson College, Emory University, Harvard University [top surgeries only; mastectomy and breast augmentation], New York University, Portland State, Stanford University, + the UCs).
I just wanted to post this list for trans* folks in the UC system who might not know about these services and may need them. I’ve also used the counseling services at UCLA (CAPS) and they are very queer/GSM-friendly. You can see a list of counselors at UCLA here.
