## Quick answer When you undergo a Permanent Change of Station (PCS), your TRICARE coverage doesn't "break," but you must update your address in DEERS immediately to ensure access to local care. Once moved, you have 90 days from the date of your move to change your TRICARE plan or find a new Primary Care Manager (PCM) under a Qualifying Life Event (QLE) rule.

## In detail A PCS is considered a Qualifying Life Event (QLE). This means you aren't stuck with your current plan if it doesn't work at your new duty station. However, your coverage does not automatically transfer; you must take proactive steps to maintain your benefits.

### 1. Update DEERS First Before calling a contractor or switching plans, you must update your address in the **Defense Enrollment Eligibility Reporting System (DEERS)**. If DEERS has your old address, your claims at the new location will likely be denied because the system thinks you are seeking "out of area" care.

### 2. Choose Your Path Based on Plan Your options depend on which plan you currently have and where you are moving.

* **TRICARE Prime (Including Select and Remote):** * If staying in a Prime Service Area (PSA), you must assign a new Primary Care Manager (PCM). * If moving to a remote area, you must switch to TRICARE Prime Remote. * **The 90-Day Rule:** You have 90 days from the date of your move to update your enrollment. If you miss this window, you may have to wait until the next Open Season. * **TRICARE Select:** * Your coverage follows you, but you need to find new network providers in your new region (East or West). * **TRICARE For Life (TFL):** * TFL is valid wherever Medicare is accepted. Ensure your address is updated in DEERS and with the Social Security Administration.

### 3. Regional Contractors (2026 Update) As of 2026, the TRICARE landscape is divided into two regions. If you move across the Mississippi River, you will likely change regional contractors: * **TRICARE East:** Managed by **Humana Military**. * **TRICARE West:** Managed by **TriWest Healthcare Alliance** (effective Jan 1, 2025).

Table: Action Items by Move Type

| Move Scenario | Primary Task | Plan Change? | | :--- | :--- | :--- | | **Within the same region** | Update DEERS & request new PCM | Usually No | | **Across regions (East to West)** | Update DEERS & enroll with TriWest | Transfer Enrollment | | **Stateside to Overseas** | Update DEERS & enroll in Prime Overseas | Yes (Contact International SOS) | | **Active Duty to Retirement (with PCS)** | Update status in DEERS & pay enrollment fees | Mandatory Enrollment Change |

### 4. Pharmacy Benefits Moving does not change your **Express Scripts** pharmacy benefit, but it may change your access to military pharmacies. If you use Home Delivery, update your shipping address in the Express Scripts portal immediately to avoid missing maintenance medications.

## Who this applies to * **Active Duty Service Members (ADSMs):** Must remain in Prime. They must coordinate with their new unit and regional contractor to assign a local military or civilian PCM. * **Active Duty Family Members (ADFMs):** Can choose between Prime and Select at the new location. A PCS allows them to switch between these plans outside of Open Season. * **TRICARE Reserve Select (TRS) Members:** Must update DEERS to ensure they are being billed correctly and have access to local network providers. * **Retirees:** If moving during retirement, a change of address is still a QLE, allowing for plan changes (e.g., switching from Select to Prime if a PSA is available at the new home).

Common scenarios

**The Cross-Country Move (East to West)** Staff Sergeant Miller moves from Fort Liberty, NC (East Region) to JBLM, WA (West Region) in 2026. After updating DEERS, he contacts **TriWest Healthcare Alliance** to enroll his family in TRICARE Prime. Because he is Active Duty, his 2026 out-of-pocket costs remain $0. His spouse, on TRICARE Select, now looks for West Region network providers to keep her 2026 copays at the lower network rate (e.g., ~$21–$38 for primary care depending on Group A/B status).

**The Overseas OCONUS Move** A Navy family moves from San Diego to Naples, Italy. They must contact **International SOS** to enroll in TRICARE Prime Overseas. Their care will now be managed by the local Military Treatment Facility (MTF), and they must follow specific TOP (TRICARE Overseas Program) rules for specialty referrals.

**The "Move to the Woods" (Remote)** An Army Recruiter moves to a rural town 60 miles from the nearest base. They switch from TRICARE Prime to **TRICARE Prime Remote**. They still pay $0 out-of-pocket in 2026, but their PCM is now a local civilian doctor instead of a military provider.

## Related terms * **Qualifying Life Event (QLE):** A specific change (like a PCS, marriage, or birth) that opens a 90-day window to change TRICARE enrollment. * **DEERS (Defense Enrollment Eligibility Reporting System):** The global database of uniformed service members and their families used to verify TRICARE eligibility. * **PCM (Primary Care Manager):** The doctor responsible for your basic care and referrals under Prime plans. * **Prime Service Area (PSA):** A geographic area where TRICARE Prime is offered, usually within 40 miles of a military hospital or clinic. * **T-5 Contract:** The current TRICARE contract (active as of 2025/2026) that transitioned the West region to TriWest Healthcare Alliance.
