TriWest Insurance Coverage for Veteran Drug & Alcohol Rehab

Veterans that have VA healthcare benefits, have a TRICARE plan, or qualify for using the VA Community Care Network may be eligible to seek care through the TriWest Healthcare Alliance. TriWest has helped veterans of all walks of life obtain quality healthcare services, including those for mental health disorders or substance use disorders (SUDs) for years.

What is TriWest?

Since 1996, TriWest Healthcare Alliance has been administering the Department of Defense’s TRICARE program and the Department of Veterans Affairs (VA) Community Care Network in regions 4 and 5 (the western United States and Alaska).1 TriWest serves the health care needs of military and veteran communities. With a network of 700,000 health care professionals, veterans can rest assured that they’ll receive quality care through their TriWest plans.2

TriWest vs TRICARE vs VA Benefits: What’s the Difference?

You may see the terms TriWest, TRICARE, and VA Benefits thrown around and wonder what the difference is. It can be confusing and complex to navigate the programs available to you as a veteran. To help you understand the differences, here’s a brief explanation of each program:

  • VA Benefits: VA health benefits are available to most veterans, and cover a variety of standard health benefits, including annual checkups and treatment as well as specialist appointments, like care for substance use disorders (SUDs).4 VA health benefits provide vets with access to quality care, but many vets opt to use VA benefits in conjunction with other insurance, such as TRICARE plans or private plans.
  • TRICARE: Active-duty service members, veterans, and their dependents are eligible to enroll in a variety of different TRICARE plans, which provide coverage for standard health services (like VA benefits), as well as coverage for mental health services.5 You have to enroll in a TRICARE plan to receive coverage.
  • TriWest: TriWest is the third-party administrator of the VA’s Community Care Network for regions 4 and 5 of the United States. It is a network of providers who work with the CCN, where those who cannot receive quality care through VA facilities can receive care. TRICARE plans are accepted at TriWest facilities, as are VA health benefits.

Does TriWest Cover Rehab Treatment?

Because TriWest is not an insurance plan, it cannot provide coverage for rehab. However, as a network, it does provide rehab services, and those with VA health benefits, TRICARE plans, Medicare, Medicaid, private health plans, and federal Marketplace plans can use those benefits to receive rehab through TriWest. This means that if you’re an active-duty service member or a veteran who is seeking rehab for your mental health, substance use, or co-occurring disorder through the TriWest network, you will likely receive coverage in some capacity with your health plan.6 It’s recommended that you verify your benefits and coverage prior to seeking treatment to avoid any surprise medical costs or bills.

What Mental Health & Substance Abuse Treatment Does TriWest Cover?

TriWest provides a wide variety of mental health, behavioral health, and substance use disorder (SUD) treatment options. Many of these services may be covered in some capacity under your VA health benefits, TRICARE, or other health plan type. It’s important that you call the VA or your insurance provider to learn more about your health benefits and what levels of coverage you have.

Some common services that are provided through TriWest Healthcare Alliance include:7

  • Online/telehealth Services: Healthcare services from the comfort of your home via a video chat or phone call.
  • Inpatient Treatment: Healthcare services obtained at a hospital or rehab facility where you’ll stay overnight. This gives you the opportunity to focus entirely on your sobriety.
  • Detoxification: Specialized healthcare service where a patient is cared for while they detoxify their body of any substances in their system. This ensures any potentially harmful side effects of withdrawal are managed.
  • Outpatient Rehab: Healthcare services obtained at a facility where you don’t have to stay overnight. A variety of behavioral therapies may be used depending your individual needs.

Does TriWest Cover Medications?

If medication is prescribed for the treatment of a substance use disorder (SUD) through the TriWest network of providers, it may be covered at some level under your health insurance.8, “Prescriptions” The following medications are typically prescribed in medication-assisted treatment (MAT) for SUDs:8

  • Naloxone: In cases of confirmed or suspected opioid overdose, this medication is administered to reverse the overdose’s effects.8
  • Buprenorphine: This medication is used to reduce someone’s dependency on opioids and lessen withdrawal effects. As a partial opioid antagonist, it also is used to reduce abuse potential in the future.8
  • Suboxone: This medication is a combination of naloxone and buprenorphine, and can be used to reverse overdose symptoms and reduce or prevent withdrawal symptoms.8
  • Methadone: This medication works to block opioid effects and reduce opioid cravings, and is classified as a full opioid antagonist.8
  • Naltrexone: This medication is another full opioid antagonist, working to reduce opioid cravings and block the effects of opioid medications.8

Please note that list is not exhaustive, and other medications could be administered at a TriWest facility, depending on the situation.

What Does TriWest Not Cover?

TriWest isn’t a health plan, so there is not a list of services that it doesn’t cover. However, it’s important to note that VA health benefits or TRICARE plans typically don’t provide coverage for unproven treatments for mental health disorders, like aversion therapy.9
