So what does “in-network” really mean for substance abuse treatment?

“In-network” substance abuse treatment 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 an 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.  “Out-of-network” providers have not agreed to the discounted rates.

Treatment centers that are often out-of-network (failing to meet Joint Commission certification and a lack of credibility or relationships with insurance providers) can offer “no-cost” substance abuse treatment but then go on to use questionable billing practices that can create a financial headache for patients who need to be focusing on their recovery. 

How do you know if your insurance provider is in-network? 

The first thing you will need to do is go directly to the carrier’s website and search the provider directory. Entering in the doctor’s name and the zip code. If your doctor’s name shows on the website, that’s a good indication they accept your plan and they are in your plan’s network.

Further, our accreditation the Joint Commission will often get approval for your treatment from insurance companies who are not on our list.

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.
