TRICARE Reserve Select vs. Your Employer Plan

The Activation Cliff — Why 30 Days Matters

The 30-day Title 10 threshold is the most consequential number in Reserve Component healthcare. Below it, you and your family stay on TRS (or your employer plan). At or above it, you all become eligible for active-duty TRICARE Prime — premium-free for the duration of the orders. TRS coverage automatically suspends while you are on those orders.

The cliff is a problem when orders get amended. A 29-day ADOS run that gets cut short to 25 days keeps you on TRS the whole time. A set of orders originally cut for 31 days that gets amended down to 28 days mid-period creates a paperwork mess. And reservists called up for short-duration orders below the threshold sometimes assume they get free TRICARE during that time — they do not.

Title 32 orders, state active duty, and IDT drill periods do not trigger the active-duty TRICARE benefit. See the Duty Status Decoder for the full status-by-status breakdown.

The Gotchas — Read Before You Enroll

• FEHB eligibility disqualifies you
  If you are eligible for the Federal Employees Health Benefits program — meaning you work for the federal government in a civilian role (including most full-time military technicians) — you cannot enroll in TRS. The statute (10 USC §1076d) specifically excludes FEHB-eligible reservists. This catches dual-status technicians off guard constantly.
• TAMP eligibility blocks TRS enrollment
  You cannot be enrolled in both TRS and the Transitional Assistance Management Program at the same time. TAMP gives you 180 days of premium-free coverage after qualifying separation from active duty. During TAMP you stay on TAMP. The TRS enrollment window opens after TAMP ends.
• The 60-day enrollment window is unforgiving
  After a qualifying life event (separating from active duty, losing other coverage, marriage, birth of a child), you have 60 days to enroll in TRS. Miss the window and you wait until the next qualifying event or the annual TRICARE Open Season. There are no retroactive enrollments.
• DEERS must be current
  Your reserve status must be reflected in DEERS before you can enroll. Newly affiliated reservists sometimes hit a 30+ day lag between drilling and DEERS recognition. Confirm via milConnect before relying on the 60-day window — the clock does not stop for system delays.
• Premiums pull monthly — failed payment terminates coverage
  You designate a bank account or credit card for monthly premium pulls during enrollment. If the payment fails (insufficient funds, expired card, closed account), coverage terminates. Reinstatement requires a new qualifying event or Open Season — not a phone call to the regional contractor. Verify your designated account is current any time you change banks.
• Pre-existing conditions are NOT excluded — but pregnancy planning matters
  TRS has no pre-existing condition exclusion. However, if you are pregnant when you enroll, prenatal and delivery costs follow standard TRS cost-share rules. Compare against your employer plan's maternity coverage carefully before switching — and confirm OB-GYN network status in the TRICARE contractor for your region.

The Activation Handoff — TRS Suspends, TAMP Picks Up

When you mobilize on a 30+ day Title 10 order, TRS suspends and active-duty TRICARE begins. You stop paying the TRS premium. Your family becomes eligible for the full active-duty benefit on the start date of your orders. (Verify enrollment status in milConnect — the systems don't always flip cleanly.)

When you demobilize, you typically qualify for the Transitional Assistance Management Program — 180 days of premium-free TRICARE after release from active duty, provided the triggering order was 30+ consecutive days. TAMP coverage is essentially the same benefit as active-duty TRICARE for that window.

Dental — Not Included, Not the Same

TRICARE Reserve Select does not include dental. Reservists and Guard members buy dental separately through the Federal Employees Dental and Vision Insurance Program (FEDVIP). The legacy TRICARE Dental Program (TDP) for National Guard and Reserve members was retired effective Dec 31, 2022; FEDVIP replaced it.

FEDVIP enrollment is handled through BENEFEDS, not milConnect. Open Season runs mid-November through mid-December. There's a separate vision plan in the same enrollment portal. If you're comparing TRS against an employer plan, make sure you're comparing apples to apples — your employer plan likely bundles dental and vision.

Methodology & Source Disclosure

Premium rates. TRS premiums are set annually by the Defense Health Agency and published at tricare.mil/Costs/HealthPlanCosts/TRS. This calculator uses the most recently published official rates at time of build — Calendar Year 2025: $53.92/mo member-only and $254.07/mo member-and-family. 2026 rates are typically published in late December of the prior year — verify before relying on these figures.

Cost-share modeling. TRS uses the TRICARE Select Group B network cost-share structure for most current enrollees (sponsors who entered service on/after Jan 1, 2018). Published Group B copays are $26 PCM, $51 specialist, $35 urgent care, $105 ER. For the gross-spend modeling above, we use a 15% effective cost-share rate, which roughly approximates the published copay schedule against typical billed amounts. Your actual cost-share will vary based on the mix of care you receive — this is a planning estimate, not a quote.

Deductibles & catastrophic cap. CY 2025 TRICARE Select Group B network values: $168 individual deductible, $336 family deductible, $1288 annual catastrophic cap. Premiums do not count toward the cap. Verify at tricare.mil/Costs/HealthPlanCosts/PlanCosts.

What this tool does not model: pharmacy copays, TRICARE Young Adult premiums for over-26 dependents, non-network provider costs (Point-of-Service option fees), pregnancy and maternity coverage differences, and the value of FEHB or employer HSA contributions.
