In Network Insurance Provider Information

Cornerstone Southern California is an affordable health care provider for all levels of alcohol and drug rehabilitation. We are known as one of the best treatment centers in the country, providing quality, ethical, clinically sound treatment for individuals, families and employers. Cornerstone Southern California uses In-Network providers with your insurance company to provide plan members with specific pre-negotiated rates.

“In-network” health care providers are providers who have contracted with your insurance company to accept certain negotiated rates. You will typically pay less with an in-network provider. The difference between and In-Network and out-of network providers is that the out of network plan is not contacted with a health insurance plan. So if you visit a physician within your network, your cost will be less then if you go with an out of network provider. Insurance companies will pay less or not pay at all in most cases with an out of network provider. PPO, POS, and HMO plans make use of provider networks. Indemnity plans typically do not. “Out-of-network” providers have not agreed to the discounted rates.

To get the best rates for yourself and your family, compare plans side by side, get health insurance quotes, apply online and search for affordable health insurance.

Our former clients say it best...

Dr. Stone, I am so grateful to your program and also your generosity. I was a hopeless addict who believed there was no way of getting clean. Thanks to my sister and Cornerstone staff, I recently took my 90 day chip in N.A. Thanks, my life has been changed.

~ Isaac C.

"This was the best foundation I could have asked for to be sober. My case manager was the Best!! She showed me your life can be exciting and sober."

~ Tina H.

It is the truly caring staff that makes Cornerstone the best rehab I have been to. The best part was finally getting my depression medications right, after many others tried for 2 years.

~ Jim V.
