Options for Male, 55, in CA

I am a 55 yo male in CA, currently taking levothroid (thyroid issue), lovastatin (cholesterol issue) and tamsulosin (urinary issue, no significant prostate enlarg*ment). During the past 12 years or so, I have had two routine "trigger finger" surgeries. I also have herniated disc issues.

I have been enrolled with Kaiser for approximately 20 years, though not continuously. On a recent self-pay visit to a doctor outside of Kaiser, he suggested that I transfer from Kaiser to Blue Cross Blue Shield or Aetna or another plan, as my experience with Kaiser has been less than entirely satisfactory and Kaiser does not cover/recognize the kind of non-traditional disc procedure I would like, to try to resolve the herniated disc issue (while Blue Cross, Aetna and several others apparently do).

This doctor told me that under the new Obama Administration guidelines, my pre-existing conditions would not prevent me from joining a new plan with Blue Cross, Aetna, etc.

I am wondering whether this is really so, whether I would really have the option of coverage through another plan, given my situation.

Any guidance would be appreciated.
