What Is Aetna Mississippi?

Aetna is a nationwide health insurance provider that was founded in 1853 and began as an annuity fund for selling life insurance.³ It wasn’t until 46 years later, in 1899, that Aetna offered its first health insurance policy.³ In 2018, CVS completed its acquisition of Aetna, allowing the two companies to build an open healthcare model that is community-based.³

Today, approximately 39 million people nationwide rely on Aetna for health insurance.⁴ Aetna provides a variety of health insurance plans and services, including medical, pharmacy, and dental plans, Medicare plans, Medicaid services, behavioral health programs, and medical management plans.⁴

While Aetna Mississippi isn’t a formal name for Aetna plans offered in Mississippi, the term refers to Aetna plans that Mississippians may carry. Because Aetna offers plan options in every market—private, Marketplace, Medicare, and Medicaid—there are a variety of different plan types and coverages that may be available. Be sure to call the number on the back of your insurance card to verify your specific plan details and coverage.

Does Aetna Cover Rehab Treatment in Mississippi?

Under the federal healthcare law called the Affordable Care Act (ACA), most health plans in the United States, including Aetna Mississippi plans, must provide some level of coverage for what are considered to be essential health benefits (EHBs).⁵ Of the 10 EHBs, mental and behavioral health services are considered to be one of those.⁵

This means that services and treatment for mental and behavioral health disorders, including substance use disorder (SUD), must be covered in some capacity under your Aetna Mississippi plan.⁶ It is important to note that your plan may limit coverage to in-network providers and you may owe a deductible before coverage kicks in.

What Types of Substance Addiction Does Rehab Treatment Cover?

The extent of your Aetna Mississippi plan coverage for substance addiction treatment will vary based on the plan that you have. Despite this, your Aetna Mississippi plan should cover at least a portion of the cost of treatment for addiction to various substances, including alcohol, marijuana, opioids, heroin, cocaine, crystal meth, and prescription drugs. Be sure to check with an Aetna representative to learn more about your specific plan’s coverage details.

What Rehab Programs Does Aetna Mississippi Cover?

No two paths to recovery are the same, which means that no two rehab programs are the same. What’s more, because there are so many different types of Aetna Mississippi plans across the various markets, there’s no standardized length and limit of coverage for rehab programs. Despite this, there are a few common types of addiction treatment that your Aetna Mississippi plan may cover, including:^7,8

Medical detox: Detox occurs in a medically supervised setting to provide treatment for withdrawal symptoms as needed. Medical detox is performed to help rid the body of substances (e.g., drugs and/or alcohol).
Inpatient treatment programs: This type of program generally involves a patient staying overnight at a facility to receive around-the-clock care. This program can take a few days to a few months.
Outpatient programs: This type of program generally involves a patient visiting a facility 1 or 2 times per week to receive care and then returning home.
Intensive Outpatient Programs (IOPs): In an IOP, a patient receives more intensive care than a standardized outpatient program by attending a minimum number of hours of sessions each week but without staying overnight in a facility.
Partial Hospitalization Programs (PHPs): Also referred to as day programs, PHPs typically involve a patient attending a facility for 4–8 hours per day, multiple days per week to receive the medically supervised care they need without staying overnight.
Aftercare: Any type of ongoing or follow-up care (e.g., sober living) that’s received after rehab is completed is typically considered to be aftercare.

Does Aetna in MS Cover Mental Health and Dual Diagnosis Treatment?

Due to the ACA’s mandate, Aetna Mississippi plans should cover some, if not all, mental health and dual diagnosis options for treatment. When a patient has a diagnosis of at least two co-occurring disorders, such as anxiety, depression, post-traumatic stress disorder (PTSD), attention-deficit/hyperactivity disorder (ADHD), bipolar disorder, or trauma, and an SUD, it’s referred to as a dual diagnosis.⁹

According to the Substance Abuse and Mental Health Services Administration (SAMHSA), when a patient has both a mental health disorder and an SUD at the same time, it’s referred to as a co-occurring condition.⁹ Researchers estimate about 50% of those who experience a mental health disorder in their lifetime will also experience a substance use disorder, and vice versa.⁹ Because the conditions can exacerbate or influence each other, many recommend treating both conditions at once, which is called dual diagnosis treatment.⁹
