Rehab Centers for Serious Mental Illness and Addiction in Los Angeles

What counts as a serious mental illness, and how is it treated alongside substance use?

A serious mental illness is a condition such as schizophrenia, bipolar disorder or major depression that substantially limits daily life, work or relationships. Many other mental health conditions don’t reach that level of impairment. Co-occurring care means one coordinated plan, with psychiatric care and substance use care delivered together rather than in separate places.

Levels of care listed in Los Angeles run from medically supervised detox and residential treatment to partial hospitalization and intensive outpatient care. The city’s dual diagnosis listings cover co-occurring conditions more broadly.

Los Angeles programs for this term are mostly urban: 74 percent sit in urban areas, and 89 percent lie within 25 miles of the coast, a median of 11.2 miles away. Hollywood Burbank is the most common nearest airport, and the median distance to the nearest airport is 9.8 miles. The Los Angeles River is the river most often within reach.

Where do adults with serious mental illness get public care in Los Angeles County?

Adults in Los Angeles usually enter public mental health care through the Los Angeles County Department of Mental Health, whose 24/7 Help Line is (800) 854-7771. Public substance use treatment runs through the county Department of Public Health’s Substance Abuse Prevention and Control division. That division lists its Substance Abuse Service Helpline as 1.844.804.7500 and offers a Service & Bed Availability Tool for finding open beds. Asking either line for an assessment is a reasonable first step. Statewide, the California Department of Health Care Services licenses residential and outpatient substance use providers.

Does Medi-Cal cover serious mental illness and substance use care?

Medi-Cal, California’s Medicaid program, pays for substance use treatment through county-contracted Drug Medi-Cal providers rather than through a single list of plans. Managed care plans in Los Angeles County include L.A. Care Health Plan, Health Net Community Solutions, Kaiser Permanente and PHC California. Ask the county Help Line how mental health services are handled under your plan, and confirm payment with each program. More on Medicaid-accepting rehab is available.

Will a Los Angeles program continue my psychiatric medications?

Some programs continue psychiatric medications through admission and others don’t, so ask before you go. Useful questions include whether staff will continue antipsychotics, mood stabilizers and long-acting injectables, and whether medications for opioid or alcohol use disorder are offered. Also ask who prescribes on site and how the team coordinates with your current psychiatrist. Discharge planning matters too, including peer support specialists, supported housing referrals and links to community treatment teams.

What crisis help is available in Los Angeles?

For a mental health crisis, call or text 988, or call the county Help Line at (800) 854-7771. The Help Line can send Field Intervention Teams for in-person support. Call 911 if anyone is in immediate danger. California’s SB 43 has been in effect in Los Angeles County since January 2026. The law adds severe substance use disorder to the grave disability standard under the state’s involuntary treatment law.
