Does Centene Insurance Cover Drug & Alcohol Rehab in Los Angeles?

Yes, Centene insurance generally covers drug and alcohol rehabilitation services, but the exact benefits depend on your plan type and the state where you live. Most Centene plans, including Medicaid Managed Care, Medicare Advantage, and Marketplace plans, include substance use disorder treatment as an essential health benefit under the Affordable Care Act. This means that coverage usually extends to a range of services such as medical detox, inpatient and residential rehab, outpatient programs, intensive outpatient programs, partial hospitalization programs, and medication-assisted treatment with medications like methadone, buprenorphine, or naltrexone combined with counseling or therapy.

The best way to know exactly what is covered is to review your plan’s Summary of Benefits and Coverage or Evidence of Coverage documents. You can also call the member services number on your insurance card to confirm coverage, network facilities, and prior authorization requirements.

What Rehab Treatments Does Centene Insurance Cover?

Centene insurance covers a wide range of treatments for drug and alcohol rehabilitation, although the specific services depend on your plan and state. In general, Centene provides coverage for both inpatient and outpatient care, medication-assisted treatment, and integrated programs that address co-occurring mental health conditions. These services are considered essential health benefits under the Affordable Care Act, which means most plans must include them.

The types of treatments that Centene typically covers include:

Medical detox in a supervised setting to help manage withdrawal symptoms safely.
Inpatient or residential rehab programs that provide 24/7 structured care and support.
Partial hospitalization programs (PHPs) that offer intensive daily therapy while allowing patients to return home each evening.
Intensive outpatient programs (IOPs) that involve several hours of therapy multiple times per week while living at home.
General outpatient treatment, including individual or group counseling and ongoing therapy.
Medication-assisted treatment (MAT) with FDA-approved medications such as methadone, buprenorphine, or naltrexone combined with counseling.
Dual diagnosis treatment that addresses both addiction and underlying mental health conditions at the same time.
Aftercare and continuing support services, such as follow-up therapy, relapse prevention, or sober living support, depending on the plan.

Most plans require prior authorization for inpatient rehab, residential treatment, partial hospitalization, or intensive outpatient care. Using in-network providers helps reduce costs, and mental health parity laws ensure that substance use disorder treatment must be covered at the same level as other medical services.

What Addictions Does Centene Cover?

Depending on your plan, Centene may provide coverage for the core treatment types across many substance categories, including:

Opioids (e.g., heroin, prescription painkillers) – covered via detox, rehab, outpatient, MAT
Alcohol – usually covered across detox, rehab, MAT, and therapy
Stimulants / Benzodiazepines / Prescription drugs – typically covered, especially in residential or outpatient settings
Multiple substances / polysubstance disorders – covered through integrated or dual-diagnosis programs

Coverage is service-based, not substance-specific: Centene covers treatment types (detox, inpatient/outpatient care, MAT, counseling) which apply to various addictions

Does Centene Cover Mental Health Treatment in Rehab?

Yes, Centene insurance plans, including those offered through its subsidiary Health Net in California, generally cover mental health and substance use disorder treatment (dual diagnosis treatment coverage), including rehabilitation services. These benefits are considered essential under the Affordable Care Act, so most plans comply with federal requirements for behavioral health coverage. Covered services typically include therapy sessions with psychologists, psychiatrists, or licensed counselors, inpatient and residential treatment programs, partial hospitalization programs, intensive outpatient programs, medication management, and aftercare or follow-up services.

How Long Can I Stay in Rehab With Centene Insurance?

The length of time you can stay in rehab with Centene insurance depends on your plan type, the level of care you need, and whether the treatment is considered medically necessary. Centene does not set one standard limit for all members. Instead, coverage is based on clinical assessments, ongoing progress in treatment, and recommendations from your healthcare provider.

In general, Centene may cover short-term programs as well as longer treatment depending on your needs. Some inpatient or residential rehab stays may last 30 days, while others can be extended to 60 or 90 days or even longer if deemed necessary. Outpatient programs such as intensive outpatient (IOP) or partial hospitalization (PHP) can last several weeks to several months, and standard outpatient therapy may be covered for ongoing care over an extended period. Medication-assisted treatment for opioid or alcohol use disorder can also be covered on a long-term basis when medically appropriate.

Most Centene plans require prior authorization for higher levels of care such as inpatient rehab, residential treatment, or partial hospitalization. This means your provider will need to submit documentation showing that the treatment is medically necessary. Continued coverage is often reviewed periodically, so your stay may be extended if you are showing progress and still require structured care.

Since coverage rules can vary by state and by plan, the best way to know how long Centene will cover your rehab stay is to review your plan’s Evidence of Coverage and contact member services. They can confirm the number of days approved initially and explain how extensions or continued care can be authorized.

When is it Time to go to Rehab?

Deciding when it’s time to go to rehab can be difficult, but there are several clear signs that professional treatment is necessary. If substance use or addictive behaviors are starting to interfere with daily life, health, or relationships, it may be time to seek help. Some indicators include:

Loss of control over use – You find it difficult to cut down or stop despite repeated attempts.
Health problems – Physical or mental health is being affected, such as liver issues, heart problems, depression, or anxiety.
Neglected responsibilities – Work, school, or family obligations are being missed or negatively impacted.
Relationship strain – Conflicts with loved ones, isolation, or broken relationships due to substance use.
Risky behaviors – Driving under the influence, unsafe sexual activity, or other dangerous actions.
Tolerance and withdrawal – Needing more of the substance to feel the same effect or experiencing withdrawal symptoms when not using.
Failed attempts to quit – Repeated unsuccessful efforts to stop using on your own.

Rehab is appropriate when professional help is needed to safely manage withdrawal, address underlying mental health issues, or provide structured therapy and support.

If you recognize several of these signs in yourself or a loved one, it is usually safer and more effective to seek treatment sooner rather than later. Early intervention improves outcomes, reduces health risks, and provides the tools to build long-term recovery.
