Frequently Asked Questions

Does Corona Regional Medical Center accept Medicaid?

How do I start treatment at Corona Regional Medical Center?
Call the facility directly at (951) 737-4343 for an intake assessment. Our free 24/7 helpline (+1 (205) 973-2878) can also help you compare programs, verify insurance, and navigate options. No physician referral is required.
Is treatment confidential?
Yes. Federal law (42 CFR Part 2) provides strict confidentiality protections for substance use treatment records — stricter than HIPAA. Records cannot be disclosed without written consent, even to family, employers, or law enforcement.
What happens when you call? (general intake process)

Most treatment centers follow a 4-step intake: (1) confidential assessment — substance history, mental health, insurance, preferences (protected by 42 CFR Part 2); (2) insurance verification — facility contacts your plan to confirm coverage and out-of-pocket costs; (3) level-of-care recommendation — clinical staff match you to detox, residential, PHP, IOP, or outpatient based on severity; (4) admission typically within 24–48 hours. Timing varies by facility and bed availability.
