What Clients Say About Cornerstone
What Are The Advantages of Cornerstone’s In-Network Status?
At Cornerstone, we’re a trusted in-network provider for many major insurance plans, offering several advantages to make your treatment more affordable and accessible:
- Pre-Approved by Insurance Companies: Your insurance recognizes Cornerstone as a top-tier provider for addiction treatment in Southern California.
- Lower Costs for You: Because we accept many insurance plans, your out-of-pocket costs (like deductibles and copays) are usually lower or even covered, depending on your plan.
- Transparent Billing Practices: We ensure ethical billing practices with rates agreed upon by your insurance company and our treatment Center.
- Priority Placement: Due to our longstanding relationships with insurers and our high success rates, Cornerstone is often given priority placement for your treatment.
- Joint Commission Accreditation: Cornerstone is accredited and thoroughly inspected every 3 years by the Joint Commission. Joint Commission accreditations and certifications are recognized nationwide as a symbol of quality that reflects an organization’s commitment to meeting exceptional performance standards. We maintain a preferred status with health insurers.
What Does “In-Network" Really Mean?
"In-network" treatment centers, like Cornerstone, have agreements with your insurance company to accept specific, negotiated rates, which means you'll generally pay less for your treatment. Out-of-network providers don't have these agreements, so your costs will usually be higher, and insurance may pay less or nothing at all. Choosing an in-network provider can save you money and help ensure smoother billing and coverage.
