Whether you’re active duty, a retiree, or a family member, knowing your Tricare region ensures you get the care you need, when you need it.

With Tricare’s system divided into specific regions, each offering a unique set of providers and resources, pinpointing your exact coverage area might seem daunting. But don’t worry, you’re not alone in this quest. This guide is designed to simplify the process, helping you identify your Tricare region quickly and effortlessly. So, let’s dive in and unravel the mystery together, ensuring your healthcare journey is as smooth and stress-free as possible.

Understanding Tricare Regions

Identifying your Tricare region is a crucial step in accessing the healthcare benefits and services tailored to your military status. The Tricare system is divided into specific geographical areas, each designed to serve members based on their location. These regions are defined as East, West, and Overseas.

East and West Regions

  • East Region: Managed by Humana Military, the East region encompasses a substantial portion of the United States, including areas such as the District of Columbia, Delaware, Pennsylvania, Maryland, and West Virginia. If you reside in any of these areas, you are part of the East region.
  • West Region: Health Net Federal Services is the contractor for the West region. It covers states like California, Colorado, Alaska, and Arizona. Living in any of these states means you’re in the West region.

Both these regions aim to provide seamless healthcare services, ensuring beneficiaries receive efficient care.

  • Overseas Region: This is meant for active-duty service members, retirees, and their families living outside the United States. The Overseas region covers Europe, Asia, Africa, and other parts not included in the East or West regions. Participation in this region offers comprehensive coverage and support during international assignments.

Knowing your region helps in understanding the specific processes, healthcare providers, and resources available to you. For example, each region has distinct customer service contact information and online portals for managing appointments, accessing health records, and contacting support.

By accurately determining your Tricare region, you’ll streamline your healthcare experience, ensuring you’re utilizing the services and benefits most relevant to your location. Keep these regional distinctions in mind whenever you need health services, support, or information specific to your Tricare coverage.

Identifying Your Tricare Region

Determining your Tricare region is crucial for leveraging the healthcare services and benefits tailored to your military status and location. This section guides you through the steps to identify whether you belong to the East, West, or Overseas Tricare region.

Verify Your Address

Start by confirming your current address is updated in DEERS (Defense Enrollment Eligibility Reporting System). Your Tricare region depends on your official residence. Log into the DEERS system online or contact a local military ID card office for assistance.

Use the Tricare Plan Finder Tool

Tricare provides a Plan Finder tool on its official website. Inputting your zip code and beneficiary category, the tool indicates your Tricare region and available plans. This tool is especially useful if you reside in the U.S.

Consult the Regional Maps

Tricare’s official website hosts detailed maps dividing the U.S. into East and West regions. These maps outline which states fall under Humana Military (East) and Health Net Federal Services (West). If living in the U.S., locate your state on these maps to discern your region.

Determine Overseas Eligibility

If you reside or are stationed outside the United States, you’re likely part of the Overseas region. The Overseas region encompasses all locations outside the U.S., offering specific plans for individuals and families living internationally.

Contact Tricare Support

When in doubt, reaching out directly to Tricare support can clarify your region status. They offer dedicated lines for each region and an Overseas assistance line. Provide your location or intended move, and they’ll confirm your Tricare region.

Identifying your Tricare region, whether it’s East, West, or Overseas, empowers you to access the right healthcare services and benefits. This knowledge simplifies navigating Tricare’s system, ensuring you and your family receive optimal care wherever you are stationed.

Different Types of Tricare Plans and Their Regional Availability

Having established the importance of identifying your Tricare region, it’s equally crucial to explore the different types of Tricare plans and their availability across these regions. Tricare plans are tailored to meet various healthcare needs, taking into account factors like age, location, and military status. Here, you’ll navigate through the primary Tricare plans, focusing on their regional distribution, ensuring you’re well-informed about the options accessible in the East, West, and Overseas regions.

Prime Options

  • Tricare Prime: Available in all regions, this plan requires enrollment and offers care through military hospitals and clinics, with assigned primary care managers.
  • Tricare Prime Remote: Designed for members in remote areas of the U.S., it’s available in both East and West regions but not overseas.
  • Tricare Prime Overseas: Exclusively for members living overseas, ensuring comprehensive coverage outside the U.S.

Standard and Extra Options

  • Tricare Select: Replacing Standard and Extra, Select offers increased flexibility in choosing healthcare providers. It’s available in the East, West, and Overseas regions.
  • Tricare For Life: Serving as supplementary insurance to Medicare, it’s available worldwide, ensuring continuous healthcare coverage for eligible beneficiaries.
  • Tricare Young Adult: Extends coverage for adult children up to age 26, available in all regions, subject to specific eligibility criteria.

By aligning your healthcare needs with the right plan and your Tricare region, you’ll optimize your benefits and streamline your healthcare experience.

How Your Tricare Region Affects Your Healthcare Benefits

Knowing your Tricare region plays a crucial role in determining the healthcare benefits available to you. This knowledge ensures you make the most of the Tricare programs tailored to regions such as East, West, and Overseas. Each region not only offers unique plans like Tricare Prime, Tricare Select, and Tricare For Life but also dictates the specific procedures for accessing care and services.

Network of Providers

The availability and choice of healthcare providers differ by region. For instance, the East and West regions have distinct networks of civilian healthcare professionals who are in-network for Tricare. Consequently, if you reside in the East region, you’ll have access to a different set of providers than those in the West, impacting where and how you receive medical care.

Coverage for Services and Benefits

Your region determines the coverage specifics for various medical services and benefits. While some services are universally available across all Tricare regions, others may have regional restrictions or require additional steps for approval. Understanding these nuances can prevent unexpected out-of-pocket expenses.

Referral and Authorization Processes

The process for referrals and authorizations for specialist care varies by region. For example, Tricare Prime enrollees typically require referrals to see specialists. The specific requirements for obtaining these referrals can differ between the East, West, and Overseas regions, influencing the speed and ease with which you can access specialized care.

Cost Differences

Premiums, copayments, and cost-shares vary across Tricare regions. This variation impacts your healthcare budget, making it essential to be aware of the costs associated with your particular region. Knowing these details helps in financial planning for healthcare expenses.

Navigating the intricacies of Tricare regions ensures you leverage the healthcare benefits to your advantage. By understanding the differences in network providers, coverage, processes for referrals, and cost implications, you’re better equipped to make informed decisions about your healthcare.

Tips for Navigating Tricare Regions When Moving

Moving can complicate your Tricare coverage due to regional differences in plans and providers. To ensure a smooth transition, it’s essential to proactively manage your Tricare benefits. Here are actionable tips tailored to navigating Tricare regions effectively:

  1. Update DEERS Promptly: Your first step is updating your address in the Defense Enrollment Eligibility Reporting System (DEERS) immediately after moving. A current address in DEERS helps you avoid lapses in coverage and ensures you receive correspondence from Tricare.
  2. Explore Tricare Plan Options: Investigate Tricare plans available in your new region before moving. Plans like Tricare Prime, Tricare Select, and others may have different providers and rules in your new region. Knowing your options helps you choose the best plan based on your family’s healthcare needs.
  3. Contact Tricare Regional Office: Reach out to the Tricare regional office in your new location for assistance. They can guide you through the transition, help with plan enrollment, and answer any region-specific questions.
  4. Research Healthcare Providers: Once you’ve chosen a new Tricare plan, research healthcare providers in the new region who are within the Tricare network. Establishing care with new providers ensures continued access to healthcare services without interruption.
  5. Consider Transitional Health Care Plans: If you or a family member is undergoing treatment that cannot be interrupted, ask about transitional healthcare plans like Tricare Transitional Assistance Management Program (TAMP) that may provide continued coverage during your move.
  6. Keep Important Documents Accessible: Keep copies of medical records, prescriptions, and any ongoing treatment plans easily accessible during the move. Sharing these with your new healthcare providers will help maintain continuity of care.

Navigating Tricare regions efficiently requires planning and communication. By taking these steps, you ensure your healthcare coverage transitions smoothly with your move, allowing you to focus on settling into your new home without healthcare worries.


Understanding your Tricare region is crucial for maximizing your healthcare benefits. By following the steps outlined, you’re equipped to navigate the complexities of Tricare regions with ease. Remember, keeping DEERS updated, exploring your plan options, and staying in touch with your regional office are key to ensuring your healthcare needs are met, especially when transitioning to a new location. Armed with this knowledge, you can make informed decisions about your healthcare, allowing you to focus on what truly matters—your well-being and that of your family.
